If anyone already uses Sideberry (and I assume TST will work as well) on Firefox and doesn't want to download an additional extension or doesn't want something quite this powerful, I wrote <a href="https://textmark.netlify.app/" rel="nofollow">https://textmark.netlify.app/</a> a week or two ago, and I've been using it as a bookmark replacement.<p>Sideberry allows selecting arbitrary groups of tabs and copying them to the clipboard as an indented list of tabs. The site I put up will reopen those tabs, preserving the order and parent-child relationships between pages. It also uses `rel=noopener` to avoid a security risk I've noticed with similar sites in the past with parent-child page references. And it has no advertising and absolutely zero user tracking (aside from Netflify serverside logs that I can't turn off), since it's a project I made for myself and costs me nothing to run.<p>Also, the entire source (minus the favicon) is in one page, so if you want to self-host it yourself for extra protection, just view-source and copy and paste. It'll work on any static web host.<p>I've found this to be a hugely beneficial replacement for bookmarking. Bookmarks are too slow and cumbersome for me, so I end up not really using them. It's also annoying to enter descriptions for bookmarks, and I don't like that all of my bookmarks need to be in the browser at the same time. This allows me to copy tabs out to separate files (I use org-mode to sort everything). And then I just keep this site pinned and use it to reopen tabs later if I context-switch. It's the closest I've ever come to being able to actually manage my browser sessions and stop my tabs from growing out of control into the thousands.<p>I was going to wait to Open Source it and write up a better explanation of the workflow I use before sharing it, but it's appropriate to share it here. It's not nearly as powerful as what TabFS is talking about (and I'm very interested to look into TabFS more, since I've been thinking about roughly the same problem, and this looks like a potentially quite powerful setup), but it's a small system that has made a big impact for me over the past week or so, and since I was already using Sideberry it doesn't require me to install anything new or open any additional attack vectors.
