Yahoo as the default search engine didn't help, either.

Firefox is about to shoot itself in the foot again. Soon, all old add-ons will stop working, as Firefox tries to get add-on developers to change to their new WebExtensions API. (Which is almost, but not quite, compatible with Google's add-on format.) Many developers are not bothering, and will drop Firefox.

[gnicholas]

Yep, I'll be limping along on the "old" version of Firefox so that I can use Tree Style Tabs, which can't be made compatible with the new extension framework. And my startup may or may not update our own Firefox extension this year. We're waiting to see how things shake out — how many people update to the latest version of Firefox, or whether folks are tied to the old version because they have so many legacy extensions.

https://addons.mozilla.org/en-US/firefox/addon/tree-tabs/ use the new extension api AFAIK. Seems you have to go through some hoops to hide the regular tabbar though.

[jhasse]

Unfortunately it draws its own context menu which looks very ugly, doesn't behave native and interferes with dom.event.contextmenu.enabled=false.

Well if you decide to stick with an older version of Firefox, you might just as well stick with PaleMoon instead. At least it's still getting some new features and security fixes.

[gnicholas]

Would love more details!

Fork of tree style tabs for Pale Moon

https://github.com/oinkin/treestyletab

[Endy]

I suggest that you switch over to development for Pale Moon. There are lots of positives behind it, and all that I've heard is that they have no plan at the moment to switch over to WebExtensions.

[richardboegli]

I second switching to Pale Moon.

Someone has forked Tree Style Tabs so that it works with latest Pale Moon.

[mavendependency]

The testpilot program from mozilla has a beta test for sidebar tabs. This is still not tree, but can be a decent alternative if you need tree style tabs to reclaim screen real-estate.

[thristian]

The sidebar tabs testpilot extension is also not a WebExtension, so it will stop working at the same time as TreeStyleTabs.

Tab Center Redux <https://addons.mozilla.org/en-US/firefox/addon/tab-center-re... is a fork of the testpilot extension that is a WebExtension, so it works fine in Firefox Nightly. It's naturally more limited than the original extension, though: it can't hide the top tab-bar, it has to draw its own context-menu, it can't be shown at the same time as any other sidebar, etc.

It's still nicer than the top tab-bar for those of us with a bunch of tabs open, though.

[vetinari]

Tab Center (the extension for sidebar tabs from testpilot) is already down, with no replacement. For existing users, it will stop working with FF56.

[kodablah]

Yup, I fear for the future of tree style tabs. So much so, I am developing an alternative browser that embeds Chromium but has a tree-style tab interface from Qt [0] (disclaimer, nowhere near ready yet).

Looks interesting!

It was the only choice.

Set your User-Agent to Firefox or IE Edge and Windows OS. You'll soon see "install chrome" pop ups/banners/warnings that take up a portion of the screen all over Google properties.

At that point why not just self-uninstall?

Out of non-Google search engines, Yahoo makes most sense even if they got no money from the deal. Maybe DuckDuckGo but unfortunately it's still not as good.

Regarding extensions, it's better this way because nobody is bothering with current API. Most new extensions are chrome-only.

[bigbugbag]

yahoo as the default search engine is the same as google as the default search engine. It is a matter of money and selling to the highest bidder, though the move away from google was probably motivated by chrome marketshare.

This is a US only move, in the EU it's still google and mozilla got a truckload of criticism for this.

[unknown2374]

They do need to make money in some way, ever since Google didn't renew their contract with Mozilla (which iirc was 98% of their revenue back in the day) after Chrome started taking off.

[kibwen]

Mozilla actually moved to Yahoo not because Google refused to renew their contract, but because Yahoo was flush with cash and desperate to gain any foothold at all in search engine share (which they did, briefly; a friend of mine at Google had the job of getting Firefox users to switch their default search back to Google). Yahoo just offered better terms than Google at the time.

[bigbugbag]

It's mozilla who didn't renew with google in the US, because yahoo needed to appear better for negotiating their price tag and made a better offer.
