If you’re going to stay on a version then you’re probably better off on Firefox ESR as the current version will keep on getting security fixes until the middle of next year (by which time hopefully the features you’re missing will have come back).

I doubt it.

What is worse about it in your opinion? I was pleasantly surprised with how well it worked, and in fact the old extension had bugs for me where hiding the tab bar wouldn’t work properly.

No native context menus.

I'm of the other opinion. The legacy one was inferior, a couple bugs here and there, but usable. The new one removed the bugs I was having, and appears to be snappier. I just wish I could move the new tab button from the bottom to the top. Code doesn't look too hard, so I'll probably add a PR myself

Same for me, there’s no VimFX or Keysnail equivalent. I’ll just stay on firefox 57-0a1 (that’s an old alpha release, where (strangely) VimFX and the good old Tree Style Tab still work) for a long time.

What problems do you have with the new version?

- Open a new window: the tabs are not there by default - You need a css hack to hide the standard bar - There’s an ugly title thingy at the top of the tab pane

> Open a new window: the tabs are not there by default

It's not ideal but not a showstopper for me. I mostly use one window, where the toolbar is restored by default, and when I open a new window I got used to clicking the toolbar button (which I moved to the left) or pressing F1.

> You need a css hack to hide the standard bar

> There’s an ugly title thingy at the top of the tab pane

I just copied the "css hack" once and forgot. The last item is solved the same way. For those who don't know:

Inside the profile folder (with a name like "xxxxxxxx.default"), create a folder called "chrome", and a file inside called "userChrome.css" with the following content:

    #TabsToolbar, #sidebar-header {visibility: collapse !important;}
    #TabsToolbar {margin-bottom: -21px !important;}

IMHO It's quick enough to do and I believe this won't be needed in a few months.

Thanks! Here's how I did it on macOS:

1. Go to about:support in Firefox URL bar.

2. the address is in "Profile Folder" row.

Thanks! I didn't know that. It seems to be like that in other OSes too. I've tried to edit my previous comment but I was just over the time limit.

Brilliant! Thank you!

it's uber slow

What OS, CPU, etc? It's pretty fast to me.

MacOS Sierra, 3.1 Ghz Intel i7, 16GB of DDR3, SSD, ...

I have no idea why it's so slow.

It's uber slow for me too. Similar specs. Several hundred millisecond tab switches with a clean profile. Typing into slack is like typing into an SSH session over a bad dialup connection. Adding Tree Style Tabs kept my CPU over 20% and my fans running permanently. Maybe it's faster for people on Windows or Linux, but on macOS it's a major regression.

Sooooo did you make a donation to the author so that they actually have a reason to spend some of their personal time on improving it beyond the initial porting effort? I mean, they have a life they need to live and time they need to allocate too, right? If it's and indispensable add-on, you can probably part with a few bucks to help get it improved to the level you need, rather than the level the author felt was appropriate.

the author of TST is refusing donations AFAIK. He also said a lot of blockages came from Firefox and not from himself. I find it a bit sad that Firefox is not making TST a prime feature of Firefox. Are no Firefox developers using TST? I find that surprising.

It's possible most of them are now using the combination of tab containers and the "snooze tabs" extension, rather than trees. A test pilot feature that lets you mark tabs as "I don't want to see you until tonight/tomorrow morning/the weekend/next week/etc". It really cuts down on the need to keep 100+ tabs open (you just silo the tabs based on their role, then snooze all the ones you don't want to lose but don't need in the slightest right now either).

I've tried the snooze things for other things and I just ended up snoozing things again and again. Nowadays it's typical to have 10-20+ tabs open at all time that you're going to need during the day. That's already too much for tabs on top
