Firefox Community Forum

I am using Firefox on my MacOS Tahoe. There is a persistent annoying issue where whenever I close (physically fold) my laptop screen and reopen it, Firefox will be frozen. It will be frozen in the sense that I am unable to interact with any tabs or anything until I manually quit Firefox and reopen it (which automatically reopens all my tabs), making it usable again. This doesn't happen every time I close and reopen my Mac, but it definitely happens the majority of the time and makes the browser hard to use.

I've attached a screenshot of what a new window looks like when Firefox is frozen. It looks just like a Firefox window when unfocused.

Notes:

• It doesn't entirely freeze Firefox. In fact, I can "switch" to a different tab by clicking on the tab and then shutting and reopening my laptop again. The new tab will show on reopening but Firefox will still be frozen. This process can be repeated.
• I can pretty consistently replicate the bug by shutting my laptop, waiting 10 seconds, and reopening it. This will almost always result in the freeze.
• The bug still happens if I'm not focused on the Firefox window but on a different app.
• The bug doesn't seem to happen if I just lock my screen but don't shut it closed.

Things I've tried that haven't fixed it:

• Updating my OS.
• Restarting my laptop.
• Disabling hardware acceleration.
• Disabling themes and extensions.
• Deleting and reinstalling Firefox, including deleting the user data in the "Library/Application Support" folder.

Let me know if there's any more information I can provide or fixes I can try. Also let me know if I should go ahead and file a Firefox bug report for this. Thank you.

I keep getting this message when I try to sign in on Firefox. Chrome let's me sign on but i much prefer Firefox. Any suggestion? {

Recently google's advanced search page changed from how it's been displayed for years -- seemingly only on firefox. And I hate the change. It still displays as always on DuckDuckGo and Safari. Firefox is my preferred browser, but I use goodle advanced search myriad times every day and this is changed version is such a PITA that it's approaching being a dealbreaker for me. Sure, I'd like to know wth happened and why, but really I just want google advanced search to return to my preferred display. (It does not just look different, it performs differently, in little ways that matter a lot to me over the multiple times I use it. Be glad to elucidate if it matters.) First attached image is what I'm now getting on ff. Second attached image is what I used to get on ff, and still get on DDG and Safari, and would like back on ff. Please help.

I recently lost all my data on my computer and after logging into my account, I couldn't retrieve my firefox data. I searched everywhere on my browser and couldn't find nothing to fix this.

I have a new computer and I want to sync my Firefox account but the Sign In button next to Sync and save data options are missing from the browsers in both devices.

How do I fix this issue?

Hi, I've been trying to access academic articles through my university library online database. My browser often directs the shibboleth authentication to the sign-in page of my previous university, not to my current ones. An example is provided below: the first link gets automatically changed to the send one. How can I stop the browser from doing this, so that I can log in through my current university account? Thanks very much!

I continued to try using the code you sent via email several times and even though it appeared to. accept the password it still rejects your code. I have tried both caps and lower case characters but it still rejects the login

We have two computers in our house -- one connection. From my computer I sent something to my daughter, the second computer in our house. For some reason, my whole Facebook account transferred to her computer ad she is unable to use her own Facebook account. We have no idea how this happened. Can anyone help? Thank you . .

I am running macos 15.7.2.

Bought a faster external drive *named EXT3* and I copied my Firefox Profiles from EXT2 *previous External* to EXT3

I have added the location for the profile in /Users/username/Library/Application Support/Firefox/profiles.ini

So far so good, but when EXT2 is NOT mounted the profile won't start, but only when EXT2 is MOUNTED then the profile will start.

Also connectivity is broken then, with that I mean I can't open any sites, not even a local one.

When I look in About:profiles I see that the profile in EXT3 is active and in use.

Any idea what is going on?

Ps:

macos: 15.7.2 Firefox Version:140.5.0 ESR

I get an error message when trying to login to the Social Security website with Firefox. Works with Chrome. The problem just started. Here is the error message.

I used to be able to ask a question on Firefox and get an answer. Now when I ask for information all I get is advertisements pertaining to the question I am asking.

Hi, I'm running Firefox 145 on a MacBook Air, with MacOS 12.7.6 (Monterey). When I try to add a bookmark to an existing folder on the Bookmarks Toolbar, it will not show up. It does show up if I go to the hamburger menu, and then Bookmarks/Recent Bookmarks, but not from the Toolbar. This is true for any folder on the Toolbar. I do not have this problem with Firefox 145 on Linux Mint Cinnamon. Is this a bug or a feature? Please advise, and thanks.
