Hello:

When I signed into my computer this morning, a pop-up asked me if I wanted Firefox to update. I let it do that, and then a pop-up came up letting choose among some photos and art for a desktop background. It even let me upload a photo of mine. I chose one of yours, now I can't change to any other photo I have on my computer. Please help.

Thank you,

Cynthia M.

You have invited me to download a new version of Firefox.

So What do I do with my existing Firefox?

If I don't like it, can I go back?

Please let me know.

I need to speak with someone. Firefox was updated on May 23. I have been away and can not use new version. I can not get access to aol account. I want my old Firefox back

If I have to restart my computers when I am in the middle of working because Firefox won't work unless I do, I will find another browser. And yes, I have it set to only update when the computer is not being used, but obviously that does work. Maybe give me the option to set a time to restart?! Like the middle of the night as opposed to the middle of a working day!!!!!!!!!!!!!!!!! Really???????????

My C hard drive is almost full. How can I get Firefox to run from the D drive? I tried copying the files there but it would not run. Do I need to edit something in the Registry? I'm using (for as long as I can) Win 10 on a Dell desktop. Latest version of Firefox is installed.

Thanks for any assistance.

Today, when I went onto Vanguard, at the top of page it said my browser is not supported. However, Firefox says it is "up to date." It had already been changed to 115.24.0esr, as my macbook uses 10.13.6 High Sierra. Firefox says I am good and supported until August 1, 2025, but I am still getting the non-support message on the Vanguard site. Who is right?

Just updated to 139.0.1 and got a surprise. My New Tab Favorites Icons now have Push Pins in their upper left corners, leaving less space for the icons, so of course my icons are now smaller than before. Why do the people maintaining the system at Mozilla keep messing with the New Tabs? Last time, they thought they needed to include a large image of the Firefox icon, again shrinking the remaining screen real estate for my icons. That got fixed. Now they decided each favorite icon needs a rather large push pin to indicate that it belongs there. Somebody thought this would be a good idea? Why can't they just leave it alone?

I'm posting two screenshot images of my New Tab screen. You will know which is before and which is after.

So today I allowed an upgrade of FireFox to version 115.24.0.esr (64bit).

Now both extensions fail... uBlock Origin AND Proton Pass These were last updated May 27th and May 19th.

uBlock Origin manages to "pop up" a blank sub window.

Proton Pass starts an infinite loop displaying, then erasing itself and re-displaying:

Welcome to Proton Pass An error occurred while resuming your session Retry (button) Sign Out

Is there a way to go back to a previous version of FireFox?

Yesterday (Sat 5/31), I woke up to the 139.0.1 update, along with a new behavior that Firefox will hang (and require a Force Quit) any time I click a pinned extension that opens a drop-down interface (e.g. 1Password, Adblock Plus, Pocket).

I've tried disabling all extensions and bringing single ones back (as well as disabling Pocket via about:config) - the result: any extension that opens a dropdown causes the hang, and any extension that runs without opening a dropdown works just fine, regardless of the combination of extensions that are enabled/disabled at the time.

I tried opening Troubleshoot Mode (although it's of little use since my problem seems rooted in extension behavior) - the first several times I tried, it ALSO caused a hang, but now I'm able to turn it on & off without an issue (though the page rendering is wonky within it - I imagine that's just a Troubleshoot Mode thing?). For whatever it's worth, I think the change that preceded it starting to open without hanging was my disabling this [setting] (though it didn't cause any change in the original behavior, which was my initial goal).

I'm running macOS 14.6.1 if it's of any use. Thanks for any troubleshooting ideas!

So I just noticed after downloading the new update to Firefox, version 139.0.1 that something new came up in my task manager called Crashhelper. Never seen this before. Closed it down and it seemed to have no issues shutting down at least. I haven't had Firefox crash in recent months, so I'm assuming that this cropping up might be a glitch of some kind? I looked this up to see if anyone else had this issue, and it seems someone on Reddit did encounter this, on Linux, and another on Windows also seems to have run into it. How do we stop this from coming up whenever we start up the browser?
