Firefox used to start in a second on my Windows 10 PC. But lately it now takes about 10-20 secunds to start (on 143 beta). Is there any reason why it takes so much longer to start now? Is there any setting og tweak I can do to get it to start faster?

Since this week's update of Firefox Developer edition when the browser is restarted tabs do not load until I reset the browser.

I suspect an add-on but have not been able to determine which one.

This is happening on multiple (3) physical computers.

I just started a new work role and haven't been able to find the time to troubleshooting of the issue myself.

This has been very disrupting and stressful.

Hi whenever I use my Google account to sign into websites (Google, ebay, YouTube, & anyother sites,) Firefox will become unresponsive, the window containing the tab i was using becomes unresponsive, sort of. - I can't click any open Firefox Tabs, - the red 'Close' radio button is greyed-out, so I can't close any tabs or the window - right-click is unresponsive, so i can't close tabs that way, but Command-W closes the tabs normally, but the others are still unresponsive.

- i can open a new Firefox window (with &/or without Tabs,) which works normally.

- & unrelated, but earlier, Firefox was running really slowly, Youtube videos were slowed down, but audio was normal, and scrolling was slow.

Sorry for my language.

The latest versions of Firefox 141 (and 142 beta 1) do not allow the Windows taskbar to appear when I move the mouse to the bottom of the screen. This happens on Windows 10 with the auto-hide taskbar setting enabled. In previous Firefox versions, this worked fine (except for one older version where it briefly broke). I’m not running Firefox in fullscreen mode, and I have no modifications or themes that could interfere. I tested this on a fresh, clean installation of Firefox — the issue still occurs. After downgrading to versions 140 and 139, everything works correctly again. Interestingly, I also tested the Firefox 141 Release Candidate Build 1 from here: 🔗 https://ftp.mozilla.org/pub/firefox/candidates/141.0-candidates/ In that version, the issue only occurred in private browsing mode. Could someone please help me resolve this or confirm it as a bug? Thanks in advance!
