Firefox Community Forum

About two weeks ago, Firefox started randomly hanging and would stop responding. It wouldn't let me close the program and I always have to restart my system to resolve the problem. Sometimes it only takes a few minutes after restart before it hangs, other times it will be fine for hours.

I've tried multiple solutions I've found online, carefully following instructions: clearing cookies and cache, disabling all extensions, refreshing firefox, creating a new profile, deleting specific files within the Profiles folder, etc.

I've yet to make it more than four hours without the program hanging.

Any assistance or suggestions are greatly appreciated.

When I launch Firefox in Troubleshoot Mode and try to open the Settings page (about:preferences) right away, Firefox becomes unresponsive. This issue does not occur when Troubleshoot Mode is off.

I'm using Firefox 140.0.4 on macOS Sequoia 15.5.

Greetings...

I have noticed in my Windows 10 Task Manager that Firefox has an excessive number of processes active when Firefox is started with only one empty tab. By excessive, I found eleven (11) Firefox processes today, and I have yet to even start using Firefox.

I have only a simple Theme enabled and no Extensions enabled in my Firefox. I have tried deselection of the "Use recommended performance settings" but this does not appear to help. Disablement of my Theme increased the number of Firefox processes.

Any idea how I can significantly reduce the number of Firefox processes that appear in my Task Manager when I use Firefox? I really prefer to use Firefox as my go-to web browser, but lately it has become troublesome at times.

Thank you in advance for your help with the above problem. Take care...
