Firefox Community Forum

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.

I'm trying to use Firefox to fill out my tax forms, but while I can save them and view them with Firefox, they're blank when I open them with Adobe or print them. This is, to say the least, NOT USEFUL. What is happening?!?? I'm using Win10 and the latest version of Firefox, and I tried it on an old Mac with the latest version of Firefox as well.

Hi Mozilla Support,

Platform: MacBook Pro, Mac OS 12.7.6 Browser: Firefox 141.0 Tab Session Manager installed and configured

I had approx 150 tabs open. Closed Firefox in an orderly controlled manner.. Restarted machine.. Opened Firefox.. It failed to restore my tabs after restarting.

Selected from Firefox menu -> History -> Recently Closed Tabs (greyed out). Tried everything, but cannot get the tabs back. I shall be grateful for any help and advice.

Thanks and kind regards.

I tried all trouble shooting modes listed in help and reported a possible broken site. None fixed my problem so I reset Firefox and still get the following message when I try to log into my tmrs.com; Unable to connect Firefox can’t establish a connection to the server at www.tmrs.org. I have had this issue before and reported it as a broken site but am having the issue again with this and some other websites. Thank you

I've been having this issue with the Google page for a while. I use it as my homepage and every time I open it, dark mode doesn't work or even my language settings, unless I F5 several times. Other browsers like Edge, Chrome and Brave work fine. I'm only having this issue with Firefox. I tried uninstalling all plugins but it didn't help.

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!
