Actually, there are 2 things which you can do about it!
I found a URL for FF88.0.1 by playing around a bit with the standard download URL:
https://download-installer.cdn.mozilla.net/pub/firefox/releases/88.0.1/win64/en-GB/Firefox%20Setup%2088.0.1.exe
Of course this is the D/L link for Windows, but for your platform, you can copy the default download link and then replace latest
in the link with 88.0.1
.
If you cannot download or install the previous version, or if you want to keep up to date with bugfixes, then you can (at least for now!) do this:
- Open the
about:config
url - search for
proton
- Change the value of
browser.proton.enabled
tofalse
!
And there you go, the old UI is back. (At least until the dev team rips it out…
Like you, I really hate the new look. I hate those floating disconnected tabs.
