Another former Tree Style Tabs user, now on Sideberry with no regrets.

I am excited that FireFox is working this in by default so I don't have to keep fiddling with userChrome.css to get rid of the top tab bar.

Looks like we won't have nesting in Firefox's implementation which made it kinda pointless to me.

So they've copied Edge's poor implementation of vertical tabs. Blech.

Hey, look on the bright side: maybe chromium will get vertical tabs soon!

I've added commands to Tridactyl that expand/collapse the tabs I'm on in Tree Style Tabs, using their javascript API. Does Sidebery have anything like that?

Started using Sideberry over a year ago and have not looked back since. Very good stuff.

Can't agree more, have been using sidebery for about a month now, and even completely dropped chromium which I ran beside firefox for the last years to only running firefox with sideberry and container-tabs now.

I've been using vertical tabs (first TreeStyleTabs, now Sideberry for the last ~6 months) and I'm in the same boat.

Chrome is faster, snappier and works better on more websites I commonly use, but the fact that I cannot have "vertical tabs as trees" ruins the entire browser experience for me, so it's basically the only reason I use Firefox for the last decade or something.

Add NoScript and Firefox will be much faster than Chrome. It will make you aware of how much untrusted code poorly developed sites expect you to run on their behalf.

Well, turn off JavaScript in Chrome and you back to Chrome being faster. Turning off JS is obviously not a solution when the complaint is that (assuming the same amount of work) Chrome is faster for some JS.

NoScript doesn't turn off javascript. It allows you to selectively disable some scripts while whitelisting others. You can't use much of the modern web without JS but you can neuter the dozens of trackers and ad bloat some sites insist on running on your computer.

I'm well aware of what NoScript does, I'm already using it. It seems you're missing the point of the comparison.

Running uBlock Origin in “Medium mode” [1] also does wonders (= blocking 3p-scripts and frames). It’s interesting to see how many websites work in this mode, and the amount of crap you’re not seeing. Websites load so much faster. And, you can then (permanently, or not) easily whitelist some specific domains like content providers, etc. while browsing.

I switched to sideberry a while back, and yeah - very much agreed, it's leagues ahead of others in terms of base experience breadth (container tabs and whatnot are fully integrated) and customization options.

Their wiki also has a very simple and effective userChrome.css tweak to hide the top tab bar when the side panel is open. That's a rather crucial vertical space savings on a small laptop.

Sidebery is amazing. I have been using it for more than a year now and I love it.

How do panes scale for many groups? Can you manage 20, 30 panes? Or does it become annoying at this amount?

Sidebery is nice, but it's missing an API allowing other addons to interact with it. This is a big benefit of Tree Style Tabs, especially as you can even exploit it as a user.

I have 20 panes and it works fine.

How have I not heard about this in the bajillion times I whined about tab groups?

I kinda dislike that Firefox only have one good option that involves completely hiding each group currently not in use, but it functioned ith their tab containers which made it worth the hassle.

If this does too, I'm switching permanently

I use Sidebery, and I added some custom userChrome.css to have the sidebar collapse to only take up 36px, and expand on hover, absolutely love using it
