Ask HN: What Firefox/Chrome extensions do you use?

No one mentioned <i>Xmarks</i> (almost all browsers) to sync bookmarks and tabs between browsers<p><i>OneNumber</i> (chrome) which checks for Gmail, GReader, GVoice and wave for updates.<p>Then I would recommend <i>Boomerang for Gmail</i> (both FF and Chrome) that allows you to postpone an email to send to whenever you want.<p><i>Google Dictionary</i> (chrome): double click a word and it shows you the definition - really unobtrusive<p><i>Lazarus:Form recovery</i> (chrome) - if you were typing some text in a textArea/field and the browser crashes it can easily put the text back in when you open the page again.<p><i>Rapportive for Gmail</i> (chrome, but i thinks it also works in FF) - shows you details about senders, social networking accounts, etc<p><i>Stop Autoplay for Youtube</i> (chrome) - great if you like to open many videos in tabs and dont want to hear them play all at the same time

Chrome: JSONView &#38; XML Tree are awesome. I also use Rapportive w/ Gmail.<p>Firefox: Firebug, YSlow &#38; Web Developer toolbar for development. I also use ForecastFox for weather and occasionally S3Fox to check something on S3.

Adblock - After using it for a while, it becomes impossible to NOT use it, and still retain focus. Every page contains something that is fighting for your attention when it's not in use.<p>Firebug - Incredible client-side development tool.<p>Show anchors - Reveals anchors (&#60;a&#62; tag) in the page, making it easy to make more precise links into pages.<p>Tamper data - Makes it possible to modify browser requests before submitting them to the server. Great addition to Firebug as a development tool.

I used to have a lot more extensions installed on Firefox, but right now all I actually use is:<p>AdBlock Plus, Download Statusbar, and Tab Scope.<p>Although one personal 'hack' almost counts: I moved the bookmark toolbar up next to the system menu, to use up all that space and give me quick access to all the sites I read. I have about 14 folders up there, and the Readability bookmarklet. I'm nervous about FF4 because I don't know where I'll be able to put my bookmarks...

Chromium:<p>Adblock + Browser Button for Adblock (obvious...)<p>Chromium Wheel Smooth Scroller (similar to iPhone kinetic scrolling)<p>Google Mail Checker Plus (obvious)<p>Instachrome (integration with Instapaper)<p>iReader (similar to Safari Reader)<p>Pinboard Tools (integration with Pinboard bookmarks service)<p>Reader Plus (changes the default theme of Google Reader among other customizations)<p>Redgur (shows all imgur stored images present on a page)<p>RSS Subscription Extension (obvious)<p>Search Preview for Google (website previews on search results)<p>Send using Gmail (mail_to integration with Gmail)<p>Stylish (similar to Greasemonkey but for CSS styling)

Adblock<p>builtwith - tries to tell you what tech sites use under the hood<p>delicious bookmarkts - official<p>docs PDF/powerpoint viewer - opens PDF links with google docs viewer instead of adobe<p>eye dropper<p>goo.gl url shortener<p>gmail checker plus<p>ireader - reading format<p>lastpass<p>linkpush - saves link for opening on android (has an app on anroid you open to get that link)<p>measureit! - measure pixels between stuff<p>rss subscription extension - adds fireefox like detection for RSS feeeds<p>stayfocusd - 30 mins of HN/facebook etc a day

I use several Firefox addons, most of them have been already mentioned. However, one of my favourite addons has not been mentioned:<p>Quieturl<p>This addon transforms urls that are plain text into clickable anchors. Very very handy, I couldn't browse without it now.

AdThwart (never fails) : <a href="https://chrome.google.com/extensions/detail/cfhdojbkjhnklbpkdaibdccddilifddb" rel="nofollow">https://chrome.google.com/extensions/detail/cfhdojbkjhnklbpk...</a><p>AutoPagerize (awesome) : <a href="https://chrome.google.com/extensions/detail/igiofjhpmpihnifddepnpngfjhkfenbp" rel="nofollow">https://chrome.google.com/extensions/detail/igiofjhpmpihnifd...</a><p>Google Translate (v handy) : <a href="https://chrome.google.com/extensions/detail/aapbdbdomjkkjkaonfhkkikfgjllcleb" rel="nofollow">https://chrome.google.com/extensions/detail/aapbdbdomjkkjkao...</a><p>Shareaholic (mainly for the instant short goo.gl urls) : <a href="https://chrome.google.com/extensions/detail/aapbdbdomjkkjkaonfhkkikfgjllcleb" rel="nofollow">https://chrome.google.com/extensions/detail/aapbdbdomjkkjkao...</a><p>Smooth Gestures (speeds things up) : <a href="https://chrome.google.com/extensions/detail/lfkgmnnajiljnolcgolmmgnecgldgeld" rel="nofollow">https://chrome.google.com/extensions/detail/lfkgmnnajiljnolc...</a><p>Smooth Scroll (easier on the eyes) : <a href="https://chrome.google.com/extensions/detail/cccpiddacjljmfbbgeimpelpndgpoknn" rel="nofollow">https://chrome.google.com/extensions/detail/cccpiddacjljmfbb...</a><p>These could all come standard in my view and most people would appreciate it.

Chrome (main browser) Extensions:<p>* AdBlock<p>* Firebug Lite for Google Chrome<p>* Minimalistic Google Reader<p>* RSS Subscription Extension (by Google)<p>--<p>Firefox (for development, where some extensions in Chrome aren't available) Add-Ons:<p>* Firebug<p>* JSONView<p>* Live HTTP Headers<p>* Modify Headers<p>* Page Speed<p>* User Agent Switcher<p>* Web Developer Toolbar<p>* YSlow<p>--<p>I also have a folder of bookmarklets on my toolbar in Chrome:<p>* Google Analytics: Last Week<p>* Huffduffer: Add<p>* Instapaper: Add<p>* Pinboard: Add<p>* Twitter: Remove @mentions<p>* Readability<p>* Inject jQuery

I forget what it is called, and am on my mobile now, but I use one which loads the next paginated page below the one you are viewing, so hacker news becomes one long page for me. only loads the next age when you get down the page. love it.<p>also one to tweet the page I am viewing. I use twitter as more of an annotated favorites/bookmark list than anything else: twitter.com/liamjford

I think I'm the only person that doesn't use adblock.<p>Anyways on chrome: ireader, google reader "note in reader", hckr news (never noticed what it does though), and delicious. Using the dev channel build of chrome.<p>On FF: Treeview, someone on hn suggested it to me and I'm really hoping something similar comes to chrome. I'd use firefox more but still experience it memory leaking/crashing too much.

Firefox:<p>Wappalyzer <a href="http://wappalyzer.com" rel="nofollow">http://wappalyzer.com</a><p>Adlock Plus <a href="http://adblockplus.org/en/" rel="nofollow">http://adblockplus.org/en/</a><p>Flashblock <a href="http://flashblock.mozdev.org/" rel="nofollow">http://flashblock.mozdev.org/</a><p>NoScript <a href="http://noscript.net/" rel="nofollow">http://noscript.net/</a><p>Firebug <a href="http://getfirebug.com/" rel="nofollow">http://getfirebug.com/</a>

Firefox: - Firebug (my life wouldn't be same (or sane) without it) - Remove cookies for site (one click to remove all cookies for current domain, essential when developing cookie based sites) - FireGestures (lets you go back, reload, close tabs, etc. by preconfigured right click gestures - a feature invented by Opera I believe, I can't browse without it) - AdBlockPlus (I hate to admit this but a news site I visit frequently is so loaded with flash ads that my machine almost becomes unresponsive upon visiting)<p>Chrome: I try to find the same extensions as for Firefox but: - Firebug lite was missing the "Net" panel last time I checked - I haven't found a gestures addon that doesn't suck - I haven't found a remove cookies for site add-on<p>So migrating to Chrome has been quite hard for me.<p>PS. Yes, I'm a web developer

Firefox: Adblock, Flashblock, Leechblock, Firefox Sync, Tab Kit, Copy Plain Text.<p>Edit: oh, also Readability.

NoScript, possibly the best thing about FF.<p>Firebug, pretty handy.<p>Tamper Data, for viewing HTTP headers and tampering with them.<p>ShowIP, shows the current website's IP.<p>leetkey, great for text transformations, various encoders/decoders.<p>Screengrab, for taking screenshots.<p>Scrapbook Plus, for archiving pages (can also do some light crawling with it)<p>Mozilla Archive Format, also for archiving pages.<p>Delicious Bookmarks, for bookmarks.<p>AppTab, to make tabs sticky.<p>OptimizeGoogle, to make Google searching better.<p>UnPlug, for downloading embedded content.<p>DownThemAll, for downloading things.<p>HTTPS-Everywhere, redirects to HTTPS versions of certain websites.<p>ErrorZilla Plus, makes error pages more useful.<p>Those are the best ones, I use various other extensions depending on what I'm doing. I have a few addons deactivated at any given time.

Firefox:<p>Web Developer Toolbar, Firebug, DownThemAll!, ColorZilla<p>Frankly, all I ever use Firefox for anymore is testing/development and big or multifile downloads (DownThemAll! is kind enough to autosuspend and resume with the often wonky wifi I'm usually connected to).<p>Chrome:<p>Web Developer Toolbar, Readability, Flash Blocker<p>The version of the Web Developer Toolbar for Chrome is extremely limited, but it fills a few holes in the built-in developer tools. I'd love to have a download manager comparable to DownThemAll! for Firefox, but the Chrome API prevents most of the features I like from being implemented. Oh, well.

I don't use Chrome (privacy issues), but for Firefox,<p>* Flashblock<p>* Greasemonkey<p>* Firebug<p>* It'sAllText (which allows the use of an external editor)<p>* A few mostly inconsequential ones, like IdentFavicon, etc.<p>I find that flashblock takes care of most of my ad-blocking needs, and the rest I can do with a local DNS server. The re-emergence of badly behaved Javascript (Remember when all we had to worry about was scrolling/blinking text and alert() boxes? Those were the days.) is what prompted me to install Greasemonkey; I've got a little script that wipes iframes and kills window.XMLHttpRequest, for example

I have a lot, but Ultimate Chrome Flag is my favorite.<p>The reason it's my favorite is because it displays in the URL bar the pagerank of the site I'm on. It's like an instant credibility check whenever I'm browsing or reading an article. In fact, browsing without it (say on my phone or in my newsreader) now feels like an incomplete experience.<p>My favorite extensions in Firefox are tied, Firebug and the Web Developer Toolbar. I'm sure if either got a full-fledged extension in Chrome, it'd probably be my new favorite extension.

Firefox.<p>It turned out I couldn't live without Ubiquity. Still under development, although officially it's on hiatus.<p>The Add-On Compatibility Reporter, so I can run edge versions of extensions.<p>Firemacs (for sensible Emacs bindings)<p>TabKit (tabs on left side and tree style, with grouping and so on) and Ctrl-Tab (LRU tab switching, plus thumbnailed tab display and switch to tab by name-typing). All other tab organization systems pale in comparison.<p>And the rest: NoScript * Firebug * Web Developer Toolbar * Greasemonkey * IETab * Vacuum Places DB <i>

Gmail Checker (Official one by Google)<p>Rapportive<p>Chrome 2 Phone<p>Google Voice<p>Lastpass<p>Google Reader<p>Craigslist Comprehensive Cleanup<p>Craigslist Preview<p>Facebook Photo Zoom<p>Extension Gallery Inspector (Invaluable if you want to know what an extension is going to do BEFORE you install)<p>TackyNotes (I should note that I don't really use this, I just have it installed because I wrote it. I suppose the fact that I don't use it is a good indicator of why I've lost interest in developing it. They say it's best to write software to fix a problem you have or someone else has and I think that kind of missed the mark.)

Chrome dev channel:<p>AdBlock<p>Aviary Screen Capture<p>Awesome Screenshot - (to capture the whole page)<p>Better Facebook Fixer<p>Chromey Calculator<p>DayHiker - For Google calendar. Check schedule and tasks from toolbar.<p>Docs PDF/PowerPoint Viewer (by Google)<p>Forecastfox Weather<p>Gmail Notes (Beta) - Add notes to conversations in Gmail and save these notes to Google Docs.<p>Gmail StrikeThrough - Enable StrikeThrough in Gmail or Google Apps Mail.<p>Gmail Unread Message Count in Favicon<p>Google Calendar Dynamic Icon - Changes the number on the Google Calendar favicon to reflect the current date<p>Google Chrome to Phone Extension<p>Google Mail Checker Plus<p>Google Voice (by Google<p>Graph Your Inbox - Visualize your Gmail data.<p>Novell Moonlight<p>Rapportive - (Disabled)<p>Speed Dial<p>Tab Sugar

Firefox: Firebug, Pagespeed for finding slowdowns in my pages. WebRank toolbar for when I'm too lazy to open Market Samurai.<p>Chrome: Eyedropper for stealing a color. Nofollow eyes to make sure my pages aren't wasting pagerank. SEOQuake for when I'm too lazy to open firefox/MS. Ultimate Chrome Flag. I like seeing ips/locations/etc. Chromed Bird for my twitter accounts that are for business.

AdBlock, FlashBlock, Readability and Instapaper. The web is an obnoxious assault on the senses. There is some useful stuff in between all those flashing billboards and neon lights so I block all of the distractions that I can. I wish there was a SocialNewsBlock plugin to get rid of all of those damn buttons everyone puts on their sites, too.

On chrome i use:<p>* Notscript (blocks javascript, not as good as noscript for firefox but imho still good)<p>* Adblock<p>* Navigate on paste (load webpage with middle click on linux)<p>* Type ahead find (just start typing to search)<p>* android2cloud (send urls from your mobile phone to your browser)<p>For Firefox:<p>* TabMixPlus (Multiple rows for tabs)<p>* NoScript (JavaScript blocker)<p>* AdBlock Plus<p>* FoxyProxy (easy managable proxys)<p>* AutoAuth (automatically submits saved http basic authentication dialogs)<p>* Locationbar² (easy access to url segments)<p>* Firebug

I use many of the ones people have mentioned here, but in Firefox. Can't switch to Chrome because it doesn't have a good implementation of two of my favorite add-ons:<p>Stumbleupon - for whenever I need a distraction that even HN can't fullfil<p>Colorzilla - For getting colors of web pages; use this about a dozen times a day

Vimperator - make Firefox more like Vim

Just the important ones:<p>BetterPrivacy (LSO Cookie Remover)<p>Firebug (+ Firecookie)<p>Hackbar<p>NoScript<p>Tree Style Tab<p>Web Developer Toolbar<p>All of which have no (satisfactory) Chrome equivalent and thus prevent me from switching ;)

The only one I use that hasn't been mentioned here yet is Venkman (JavaScript Debugger) for FireFox.

For Safari:<p><i>Gmail Checker</i> - Adds an icon to the toolbar with a badge of how many new emails I have.<p><i>Helvetify</i> - Forces Helvetica Neue as the font for all websites.<p><i>Facebook Photo Zoom</i> - Zooms photo thumbnails on Facebook so you don't have to reload the whole page when you want to see a photo.

On Chrome:<p>Adblock, RSS Subscriber (puts an RSS icon on the location bar where relevant and allows you to subscribe to the feed).<p>I also wrote my own delicious extension to easily add bookmarks into delicious.<p>On Firefox: Firebug, Adblock<p>I basically only use firefox these days for debugging web apps.

What is the FF extension called that lets you type to search the addons you have and also lets you see a text list of all the addons you have (enabled and disabled). I used to have it but I switched computers...

Since I like a fast, non-cluttered, browser I have only one addon installed in Chrome. "No More Tabs" protects me of opening 40+ tabs and telling myself all the time "Don't close it, you might need it again!"

Firebug<p>Greasemonkey<p>S3Fox<p>ColorZilla<p>DownloadHelper<p>Vacuum Places<p>... and a shameless plug for Compass, a Firefox/Chrome/Safari add-on I wrote that adds a "table of contents" to various e-commerce sites to help you find stuff faster. Search for "compass" on the various extension galleries if you're interested.

AdBlock Plus, ColorfulTabs, Downthemall, FaviconizeTab, Favicon Picker 3, Greasemonkey, Greasefire, IdentFavicon (obviously, I am into icons), Quickpagezoom, TabRenamizer

Different at work and at home. Of the ones not already mentioned here my favorite is Add Bookmark Here. Adds some very simple functionality that is sorely missing.

AdBlock Plus and FlashBlock. Mostly to avoid distractions.<p>I also occasionally use Helvetireader: <a href="http://helvetireader.com/" rel="nofollow">http://helvetireader.com/</a>

I use lasttab in Firefox to get LRU tab switching. Until chrome gets it (and don't make me change my ctrl-tab muscle memory) I'm not switching.
