I am using Firefox on a Mac Mini, previously on Monterey but now on Sonoma.

Since about a month ago, any update of Firefox would cause a crash on start up, and the last working version is 118. The latest version of 121 has not fixed this problem.

Firefox would crash after a few seconds after starting up the app. I have attempted the following:

• Creating a new profile or "Refresh Firefox": same crash.
• Disabling extensions: same crash.
• Troubleshoot mode: does not crash, but does not fix anything under normal mode.
• Removing files related to Firefox before a clean install: same crash. I only deleted ~/Library/Application Support/Firefox and the app bundle – not sure if anything else could help.
• Creating a new macOS user, and install Firefox: does not crash.

I am almost ok with wiping my profile just to be able to use Firefox again, but apparently I do not know the correct files to wipe.

Greetings Firefox Community

As I long time user and supporter (have donated and even got a shirt to show!) I have never had any issues with my beloved FF. If anything minor had happened, I would always find a quick fix on the community forums.

This one is an odd ball: for a while now Firefox forgets all saved passwords but only after a cold reboot (not a restart or sleep).

It's my elderly mum's laptop, which I manage for her using a remote desktop app. It's a fairly new Asus Vivobook with Win11, fully updated and free from viruses and hacks as we have installed paid versions of both Malwarebytes and HitmanPro.Alert. My Windows desktop runs exactly the same OS and those two security software, and my FF never ever forgets anything! The only difference is that her Windows and FF are set to the Italian language while mine is English.

After trying a "refresh", I exported her passwords and bookmarks and took the drastic step of completely wiping FF and even removing profiles. Reinstalled the latest x64 version and the problem is still happening.

Had a good look at both security software to ensure there was no funny setting to cause that to occur, fact is the laptop also runs Chrome and Edge with all the same saved passwords yet those two pesky browsers never forget anything!

Personally, I'd much prefer for her to continue to use FF rather than the other two, so I am shouting out for HELP, please! Hope someone has seen this and/or knows how to fix it.

Many thanks in advance and Merry Christmas to all! Cheers Paul Perth - Australia

Dear friends,

Firefox on Linux does not allow entries in forms that are called up in IFRAME. It works perfectly on Android.

Does anyone know why this is the case? Uwe

Firefox 127.0 (64-Bit)

why are some of my YouTube videos not showing up at all in FIREFOX? also says I don't have access to "community tab" on Youtube which I do. None of these problems with GOOGLE CHROME - why is Firefox being so glitchy? its become a terrible browser.

A strange new requester appeared in Firefox today. I do not think that I clicked on anything without noticing. I was just watching a Youtube video and the requester appeared when I was moving the cursor down across the screen. The requester items would not respond, and the requester could not be closed. I had to quit Firefox and restart to get rid of it. See attached screen capture.

Hi, I have a macbook air using the sonoma os 14.2.1 with firefox 121.0 installed.

I searched sites within firefox then pinned them. When I closed firefox then turned off the mac then restarted it again then calked up firefox from the dock, all the pins were gone. I have firefox settings set to remember open tabs.

How can I keep the pinned tabs after restarting the macbook?

Cheers

On eBay, on the orders page, near the top of the list is a checkbox which when checked should cause the entire list of orders to all become checked, allowing a single operation to apply to the entire list of checked orders. Checking this box is not causing the list of orders to become checked. It works in Firefox private mode.

The problem is not being caused by any of the extensions - it persists after disabling every extension.

Windows 10, FF 121.0.1 (64-bit)

I've recently installed "OneTab" extension and right after this my firefox stopped rendering (meaning it shows in the doc as if it is running, but there is no application that can be found on the screen)

I've read articles about problems with extensions so I deleted the whole firefox folder in the "username/library/application support" as I couldn't find anything connected to the onetab extension.

I've also reinstalled firefox both from brew and by downloading from the official site of mozilla. Of course, I've restarted the system a couple of times.

Help will be appreciated. Thanks in advance.

My system is macOS Sonoma 14.2.1

In English, the meaning of this error is: Title: Configuration error Content: Failed to read configuration file. Please contact your system administrator.

I had this error for a long time. But it's not too serious. Just hit ok and I can use all the recovery tabs as before without any problems. But every time I open windows and open the browser, this message appears. I feel very uncomfortable and tired without knowing why. Even reinstalling the browser didn't fix the problem, I tried it before and lost my favorite browser theme. And 1 more thing if someone can explain. If it can't read the configuration file, how can I still use the browser? What does that configuration file do?

This message only appears when I have not opened the Firefox browser on my computer. If I already have the tab, I can open another firefox browser without that message appearing. Only when I close all tabs. Open it again and it will appear. And click ok to use normally.

from 89338383 sites just google sites have this problem. And nothing work. is so annoying ill uninstall firefox and this browser forever. 9/10 times wana go on google or yt Secure conection preblem is making me mad its an firfox account bug not the visited site have problems.

I restarted my computer today and downloaded a new version of Firefox. When I started it up again everything was gone... all Tabs, history, and bookmarks. This is a sad loss as I have been organizing my life with Firefox for over 10 years. Is there any going back and getting my firefox restored?

If I go to Safelite and start scheduling an appointment, navigating through that set of webpages will cause my computer to green screen/crash. The landing page at https://safelite.com asks for a zip code, and submitting that form puts you into the scheduling flow; after entering some details about a vehicle, I can click back and continue a few times (less than ten) to make my computer crash. I was able to reproduce the issue in troubleshooting mode. I also tried the same steps in Chrome, but it did not produce a crash.

This computer has had an issue with crashing in this manner for a while now, but this is the first thing I've noticed consistently causes a crash. I'm not expecting a solution, but I am hoping to close in on the issue; whether or not Firefox is the source here is questionable, but it does seem highly entangled.

I have been running "Ancestry.com" on Firefox" for a number of years without any issues. The last few weeks if I open Ancestry to a window that shows a family tree the window freezes and I get a notice that says "This window is slowing down your browser" and it gives me a button with a "Stop" option. When I click the button the window unfreezes for one click and freezes again. This only happens in a "tree" window, the rest of the application works OK. I have done many of the troubleshooting steps, renew refresh, clear cache etc. with no improvement. I checked with "Ancestry" the recommend Firefox or Chrome. Trying Chrome there was no problem. My preference is Firefox as Chrome is to invasive.

I am running Windows 10 (up to date), an Asus Z87 Plus motherboard, an intel core i7-4770K cpu and a EVGA GTX 650 Ti Boost gpu with all drivers up to date. I have Firefox set as my default browser.

Please advise - Thank You John H ( jrhop@hvc.rr.com)

I am using Firefox 122.0.1, Windows 11 with all latest updates. Recently my HP Laptop has been slow to respond. I rebooted and opened task manager. I started Firefox and it was using about 1500 MB of memory. I closed some tabs to try to recover some memory. However, Firefox kept taking more, more and more. After 15 minutes, it was at 10,000 MB and climbing, and my system was using 99% of memory. I don't believe Firefox did this in the past and this is clearly not working properly. Any ideas?

Hello !

I am trying out a Linux (Fedora 39) with enhanced privacy (hardened firefox with the user.js from Arkenfox). My problem is the following : When I quit a video that was in full screen with Esc. the inner window dedicated to the webpage resizes to a smaller one such as the one seen in the screenshot.

I fixed that by going into troubleshoot mode and the window went back to its original size and then reactivated my extensions but the same problem appeared when following the process aforementioned.

Any idea what could be causing this ?

Best regards,

Not sure the best way to describe the issue, but it seems like Firefox is not able to or doesn't clear memory when streaming Hulu for a while. It just slowly accumulates memory usage and eventually just hits a point where the tab crashes and doesn't continue until you close and reopen the site.

Is there a way to mitigate this or is it a known issue where it can't clear memory?

I have 32GBs of ram (about half occupied system wide), but Firefox appears to cap out globally between 7 and 8GBs, then Hulu freezes, forcing me to close the tab and go back to its home page.
