Sidebery – A Firefox extension for managing tabs and bookmarks in sidebar

I was really enjoying tree tabs and panels of the Arc browser [0] but decided to rollback to firefox so I could have something cross platform. Sidebery lets me do nested tab groups, tab panels, plus its got my bookmarks as a panel too. Performance so far is really good, with ~50 tabs anyway.<p>Only trouble is I had to go to relatively great lengths to hide my horizontal tabs: enable userChrome stylesheets, go to about:support to find my Profile folder, create a chrome folder, create a userChrome.css file and paste contents from [1], and restart. So now I have only the side bar of tree tabs, and a hot key to hide&#x2F;show.

I also use both Tab Stash and Sidebery. Tab Stash is really more for long-lasting &#x2F; bookmarked tabs &#x2F; handling various contexts in my mind and work to get back later. Sidebery on the other hand helps me manage what I currently have in mind and to juggle Multi-Account Containers in neat sections.<p>That said, I&#x27;ve actually ended up using just Tab Stash because yeah, having too much on your Sidebery tree gets messy and now you have to deal with two sets of stashes, and yeah, unlike Tab Stash, Sidebery doesn&#x27;t let you group them up into sections.<p>My only complaint with Tab Stash? I wish it retained which Multi-Account Container was used when it stashed a tab. It&#x27;d be perfect if it did that.<p>On a sidenote, I love that Sidebery lets me scroll through the tabs via scroll wheel. It&#x27;s a thing I missed since I switched to a Mac because last time I checked, you could scroll through tabs on FF Linux but strangely it&#x27;s not something you can do on Mac.

More and more browsers have sidebar (vertical) tabs natively these days:<p>* Orion (mac only) - <a href="https:&#x2F;&#x2F;browser.kagi.com&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;browser.kagi.com&#x2F;</a><p>* Brave (mac, windows, linux) - <a href="https:&#x2F;&#x2F;brave.com&#x2F;download&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;brave.com&#x2F;download&#x2F;</a> (right click any tab and then Use vertical tabs)<p>* Arc (ugh) - <a href="https:&#x2F;&#x2F;arc.net" rel="nofollow noreferrer">https:&#x2F;&#x2F;arc.net</a>

I’ve tried to switch from Tree Style Tabs to Sidebery twice now but it just isn’t reliable enough: losing my tabs on browser restart was an instant uninstall.

Sideberry also let’s you create ‘Tab Panels’ to sort tabs into different groupings. Panels can be thought of as separate windows for trees of tabs, but all within the same Firefox maim window. I use it when I’m researching a topic and want to sort tabs into subtopics. Works quite well.<p>It also meshes well with Firefox Containers, another favorite Firefox feature of mine.

Sounds like the kinda Readme that would really benefit from a picture

I&#x27;m a recent vertical tabs convert (in particular, tab trees). After just a week, it&#x27;s very hard to live without it—especially at work, where I have a bajillion tabs open at any time, and I don&#x27;t feel comfortable installing extensions that can read my bookmarks!

There&#x27;s also Grasshopper<p><a href="https:&#x2F;&#x2F;addons.mozilla.org&#x2F;en-US&#x2F;firefox&#x2F;addon&#x2F;grasshopper-urls&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;addons.mozilla.org&#x2F;en-US&#x2F;firefox&#x2F;addon&#x2F;grasshopper-u...</a>

Tab Stash is way cooler than this. I found Sidebery to be much faster&#x2F;efficient than most of the tab extensions, but I love that I can group tabs and &#x27;offload&#x27;&#x2F;archive them with Tab Stash. The only thing missing from Tab Stash was the ability to see which tab is playing audio. I installed the Sound Control extension to list tabs playing audio for that.<p>What&#x27;s missing from EVERY tab extension is I just want the ability to show tabs in a tree view, like an ASCII art tree. They all do this indented, css-styled BS that doesn&#x27;t look more compact or better. I just want an ASCII tree.<p>Anyway, look at Tab Stash for another alternative.

Nice! Can&#x27;t help but mention Simple Tab Groups [0], that basically solved all my issues with tabs. Absolutely wonderful plugin which just must be in every self-respecting browser.<p>[0] <a href="https:&#x2F;&#x2F;addons.mozilla.org&#x2F;ru&#x2F;firefox&#x2F;addon&#x2F;simple-tab-groups&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;addons.mozilla.org&#x2F;ru&#x2F;firefox&#x2F;addon&#x2F;simple-tab-group...</a>

I tried Sidebery, because my preferred sidebar extension, &quot;Vertical Tabs&quot;, has been deleted now.<p>Sidebery appealed because it combines bookmarks and tabs, something that was easy with XUL addons before Firefox Quantum. (I used &quot;Vertical tabs (simplified)&quot;, &quot;Flat Bookmarks&quot;, and &quot;Unified Sidebar&quot; and they all worked together seamlessly. Not since Firefox 57 though: all gone now.)<p>In the early versions, Sidebery was very unstable and both crashed frequently itself and sometimes took the browser with it.<p>It seems better now.<p>But I can&#x27;t drag a tab out of a window to make a window of its own, and I can&#x27;t drag tabs from one window to another. Those are <i>sine qua non</i> features for me: mandatory, and I can&#x27;t use sidebar tabs without them.

Does anyone have any tips&#x2F;tricks they use with Sidebery? Tangentially related, but I love using Firefox’s multi-account containers to access different AWS accounts at the same time (managed with Sidebery!).

In TST I right-click to “delete tabs below this one” all the time. In sidebery I don’t think there is a way to do this?

There&#x27;s also Tab Center Reborn with the ability to style it with CSS (eg I have my tabs most-recent-at-the-top)

Do you have screenshots?

For Tree Style Tabs there is TST Bookmarks Subpanel, so you can see bookmarks and open tabs at the same time.

Sideberry is a cool extension that I used for quite some time when FF was my primary browser. I have since switched to Vivaldi which has similar feature built in which works pretty well too.

I use Tree Style Tab extension in combination with Simple Tab Groups extension. Allows having multiple side panel tab trees I can switch between.

Does Sideberry sync its groups and configurations between Firefox instances running on different computers?

Can I migrate from TST to Sidebery without losing all my tabs with their tree structures?

Haha. This submission is here due to the Firefox-Chromium thread in the front page.

Tabs on the side are a hugely important part of my workflow. I don&#x27;t know how top-tabs people get through their days!<p>Some browsers have side-tabs built in, but their implementation and&#x2F;or UI is poor.<p>Other browsers can&#x27;t do side-tabs at all, even with extensions.<p>Firefox is the only browser that allows extensions to do tabs on the side properly.<p>And I&#x27;ve tried all of the extensions. Sidebery is the best presently, and the best so far.

Best firefox upgrade I&#x27;ve done lately is disabling all their &quot;Enhanced Tracking Protection&quot; features. Those are better done by adblock&#x2F;ublock extensions and disabling them significantly improved the responsiveness and speed of the browser.
