I've been trying out the nightly versions of 57 and it's really fast. Would recommend people try out the Beta.

Is Tree Style Tab working on it? I've disabled updates until further notice.

It mostly does now, I think: https://github.com/piroor/treestyletab/issues/1224

It's apparently coming along [1], but I don't think they're done quite yet

Tree Style Tab is the killer feature for me and some of my scientist coworkers. If this disappears or doesn’t work, I’ll probably use Chrome.

Which would be a shame, now that Firefox is (IMHO) better than Chrome, once again :)

Are you kidding? It's like "Blackberry is better than iPhone once again, finally losing the keyboard".

The main and only distinctive feature of Firefox was programmability (XUL, XPCOM), and now it's gone. There are forks like PaleMoon and Waterfox though but for how long.

Firefox had to take that app-platform niche (thanks to XUL, XPCOM) that now occupies Electron, but failed on that chasing after Chrome.

No, it’s not like that at all. Firefox’s performance, memory usage, and UI all far outstrip Chrome’s in my browsing now; I don’t see any reason to use Chrome apart from the usual cross-browser testing, and it’s been that way for a year (?) now.

(And Firefox “forks” have always been a very good way to be behind on security patches to no benefit.)

I have switched from Tree Style Tabs to the Test Pilot vertical tab extension (I don't remember the exact name) plus the about:config option that makes them always small, plus a few lines of userChrome.css to make the close button larger, like it was in one of the first versions. I recommend it.

It was called Tab Center, but now the experiment has ended. Is there a way to install the extension now?

Plus, there's that recent Webkit-based browser with vertical tabs as it's main feature. It was covered here on HN a few days ago.

What is it????

Vivaldi, maybe? But I don't think it has nested tabs.

Not sure if parent means this, but Vivaldi can do vertical tabs. But no idea if that is as powerful/flexible as Tree Style Tabs on Firefox. Probably not...

I wrote https://cretz.github.io/doogie/ and did a show hn a few days ago. It's chromium based though, not webkit.

Just in case you missed if above, there is a preview version of Tree Style Tab that's compatible with Firefox 57.

Edit: Actually, not a preview versions. TST just published an update and now it works on Firefox 57: https://addons.mozilla.org/en-US/firefox/addon/tree-style-ta...

Is there a Tree Style Tabs extension for chrome? I thought it was only possible in FF.

Yes, thankfully there's a nightly build[1].

Until there's a stable/signed release you have to allow unsigned extensions; set `xpinstall.signatures.required` to false.

To hide the default tab bar I needed to put the following in ~/.mozilla/firefox/xyz123-profile-here/chrome/userChrome.css

    #TabsToolbar > * {
      visibility: collapse;
    }

Some features, like autohide, aren't available with the new web extensions model, but otherwise works the same as pre-57 versions of TST.

> set `xpinstall.signatures.required` to false

This seems to only work in the Nightly and Developer channel, not with the Beta channel. Is that correct?

On developer edition here, no idea about Beta. Does the `about:config` option to disable signatures exist in your FF?

If so, make sure you grab the correct artifact to import[1]

It works now on Firefox Developer Edition 57.0b3 (64-bit), macOS High Sierra. It took me a while to figure out that one needs to activate it by clicking one of the icons at the top.

Edit: This was a really bad idea because upgrading to 57 destroyed my sessionstore.js. None of the backups were up-to-date for some reason. Be careful and make backups!

I'm just about to upgrade from 55 to either the Beta or Developer edition and was worried about this so thanks for the heads up! I probably would have anyways but now I'll be extra sure to back up my profiles first.

I think, that is correct, yeah.

DevEdition is nowadays essentially just Beta with slightly different defaults (and that option compiled in), so you could just use that.

If you really do specifically want Beta, then Mozilla also supplies Unbranded Builds with that option compiled in: https://wiki.mozilla.org/Add-ons/Extension_Signing#Unbranded...

Thank you so much! I've been searching for a way to hide the top bar for a while now.

A better modification is this:

    #TabsToolbar > * {
      visibility: collapse;
    }
    
    #TabsToolbar {
      margin-bottom: -21px !important;
    }

You can also re-enable the title bar under hamburger menu > Customize > "Title Bar" at the bottom left.

Me too. I felt numb with shock for a while after upgrading to 55.0 :D

Downgraded to 54.0 as fast as I could.

https://addons.mozilla.org/en-US/firefox/addon/tree-style-ta...

yep. I don't know if it will cleanly update; so it may lose your settings.

(Webextension ports have to spend one release in "hybrid" mode where they'r a webextension wrapped in a legacy extension shell to port settings correctly)

In addition to nightly builds of TST, there's also an alternative called Tab Tree that works with 57 and is available right from the official Add-ons site:

https://addons.mozilla.org/en-US/firefox/addon/tab-tree/

Yes! I updated at work and it didn't, but by the time I came home they'd released an update and it works here :).

The top bar doesn't auto-hide yet, the API for that will be in a future release apparently.

It’s been working great in the latest Firefox developer edition.
