I recommend this extension! It is basically equivalent to MS Edge Vertical Tabs.

Love it - Mellowtel

works well, i can now see my tabs in full screen without having to move my mouse all the way up.

An incredible idea; but could be look a little cleaner and definitely optimised a better, it seems to take up way more memory than other extensions of it's kind. Speaking of similar extensions, Sidebery has a much nicer UI, is less ram-intensive, and has extra supporting-features.

I like the idea but it flickers like mad if you resize it to a small with.

Also there is now an annoying scrolling marquee along the bottom new tab button where it says "Shift-drag will create a link or a bookmark at the place the tab is dropped too". I cannot see a way to turn this off and it's extremely distracting having it moving in the corner of my vision all the time so I will have to disable this extension for now.

works as expected.

there's a youtube video by EasyOSX where he explains how to hide the Top Bar so. I recommend watching that short video if you want to only have the sidebar showing and hide the top completely.

Hoping firefox natively adds this feature soon!

does not translate the block selected on the page.

Might be useful but looks like trash. Uninstalled immediately

As a person habitually having 829 open tabs I have found this invaluable to quickly get my tab-mania under control. Love.

If unnecessary complexity as a concept were condensed into code, it would be this obtuse add-on. People like it for the same reason they like VS Code, it has an ecosystem of easily bolted in plugins to geek out over but they aren't adding very much (honestly most should have just been options bolted into the original project) and if willing to use userchrome.js still (yes it can still easily be done, more easily than porting a *.uc.js script to an add-on with either manifest version. Looking beyond the first Google result will not cause you to develop a fatal illness so maybe try it sometime, Reddit hivemind drones!) the whole functionality of this flying spaghetti monster of code can be accomplished in less than 80 lines of JS. The Floorp fork of Firefox implements (and finally effectively fixed their implementation to be usable) this functionality, is not so garish by default (it naturally integrates into the browser style and needs no extra ugly CSS selectors specific to it, what a concept!) and doesn't turn into the hot mess of TST's bad implementation of tag nesting (God forbid you try to rearrange those tabs with a mouse without becoming enraged, tried on Linux and macOS, fickle and badly implemented trash on both ) and doesn't have the "Tree Style Tabs" pendejo banner at the top with the unnecessary close icon (if they don't want it in the sidebar, they probably will just remove the add-on altogether, duh).

I know the hivemind loves this extension and so I will get some virtue signaling indignant outrage for saying this extension is garbage so the brave outraging voice of the people can feel like part of the smart crowd for 5 nanoseconds... but its garbage.

The shortcut to select text word by word has been broken by the new feature released on 4.0.16 (2024.6.9). Please enable a config settings to disable this.

ETA: A fix has been pushed and it is making its way to production: https://github.com/piroor/treestyletab/issues/3575
