Firefox Support Forum

I have been using Firefox for over a decade. My doctors systems use MyChart for communication with patients. All of a sudden, it takes minutes to load ANY and EVERY page. Their IT says it is Firefox is not compatible with MyChart. Why all of a sudden is it not compatible??? I don't want to use Edge or Chrome....especially edge.

Prompting window for primary password failed to show up after this upgrade.

1. when I opened Firefox, it did not show up. 2. when I opened about:logins, it did not show up but alerted that I should enter primary password to access passwords. There was a "Log in" button after the alert, but nothing happened after I clicked that. 3. I can't access any of my password unless I remove Primary password.

Any idea?

Windows 11 system info:

Edition Windows 11 Pro Version 23H2 Installed on ‎17/‎06/‎2023 OS build 22631.3672 Experience Windows Feature Experience Pack 1000.22700.1009.0

I get the message: "Uh oh, we couldn't load this page at the moment. Thank you for your patience as we work on this. Please try going back to the home page or logging out" when trying to login to a patient portal site. I have previously logged into this site on numerous occasions and I can login using Safari. I've cleared the cache, cookies and history, rebooted Firefox and even threw in a few chants for good measure - nothing helped! I've not changed settings recently either. I'm at a loss, can you please help? Thank you, Edouard Cantin.

For several months I have been experiencing very frequent tab crashes and overall freezes in Firefox. I have tried removing all extensions and starting in safe mode, but nothing has solved it. I have reinstalled Firefox and updated all of my drivers. There doesn't seem to be any pattern to what causes the crashes and freezes. They can happen any time and on any website. They happen around 5 times an hour. I do not know how to troubleshoot any further.

This has been a problem for a while, currently on Firefox 126.0 and Nvidia 550.78. I can work around the problem by forcing webrender to use software mode.

When using HW accelerated webrender with my Nvidia graphics card everything works fine until the PC wakes from sleep, then graphics are broken and Firefox needs restarting. Most noticeable for me is when looking at Grafana graphs they will look like random lines, and my Frigate NVR snapshots only display some of the time.

Is there anywhere in Firefox that will show a log of any error messages to do with the graphics card? I would like to try and fix the problem rather than disabling HW acceleration, but with no logs to look at that is impossible. No other programs seem to have a problem with resuming from sleep, and no error messages are shown in any of the system logs.

Didn't have this problem before but after a couple days ago, I didn't know what changes happened to my computer but most of the program wouldn't work except I have to run it as administrator. The download problem occurred when suddenly my FF always froze no matter if I closed it or not. So I just refresh my FF and copy my profile from the old backup data that FF generated and just pasted all of them on my new profile. The problem is that after I tries to download warcraft 3 maps from google drive, the download always occurs as failed. I don't have this problem when I tried it with Edge. Running FF as admin doesn't worked either. Neither as when I run FF as refresh without any extension. Downloading stuffs with IDM (Internet Download Manager) does not have any problems. Just now, I try to download a .xlsx files from my workplace websites. After I click on the download or the file itself, nothing occurs as if nothing happened. This is giving me a headaches so I came here to give it a try if anyone can help me fix this problem.

Hello,

I am experiencing an issue related to the Vanguard anti-cheat system used by Riot Games, specifically in relation to League of Legends. After installing the game and Vanguard, I am unable to open Firefox. When I try to launch Firefox, nothing happens. However, if I change the name of the firefox.exe file, I can start Firefox on a different profile, but it only works for a short period before becoming unresponsive. None of the options or tabs respond after that.

Could you please provide assistance on how to resolve this issue?

Thank you.

i cant get firefox to open main page no matter what i try. Ive download it a few times and then it ask me to no let it fix it i did and then it still wont open.use firefox more than any site. ty if you can help.

Hello everyone! I have a really nasty problem (for almost 3 years now) that I just can't get a handle on (and I don't know the root cause 100% either). Here's my situation:

• We have a self-check-in terminal (kiosk) that is used in hotels
• The terminal runs a web app in FF full-screen kiosk mode (-kiosk flag)
• 99% of the time everything works fine and without any problems
• Sometimes though, the problem occurs that the entire browser content no longer responds to touch events
• My app continues to run, we see the visual feedback from the touch monitor, but Firefox no longer responds to anything
• If you connect via AnyDesk (our remote maintenance tool), you can click with the mouse
• Even the DevTools don't respond to touch interactions
• As I said, everything is fine via mouse interaction (remote)

What I have already tried:

• Disable hardware acceleration
• Browser restart every day at 4:00AM (so far so good, but it still happens sometimes in between of these restart windows)
• Set the widget.windows.window_occlusion_tracking.enabled to "disabled" - I read that the problem could be related to that

Does anyone know the problem and can help me? It's really critical for our business, as the guest cannot interact with the device and only a browser restart helps.

One more thing: I saw today that a second Firefox.exe process was running. After killing it, it worked again. What kind of process could it be that is affecting the main app so much?

THANK YOU

This pops up every few hours. Sometimes it pops up invisible but steals focus from the main window. How can this be disabled?

I tried all methods that have been mentioned everywhere on the Internet, including policy.json, Group Policy on Windows, etc. Nothing disables this nagging yet.

I have installed firefox in my laptop for years. after latest update, firefox runs just fine only for the 1st time, then after closing the app / restarting the laptop, firefox keep giving error (attached) I have tried to refresh, run troubleshoot mode, uninstall and reinstall again at one point I was able to recreate the issue only after reinstalling firefox 126.0.1 portable version and then syncing to the profile ( run ok for 1st time, then it broke down after closing it) The problem also seems repeatable using firefox 115 protable Now, I tried to reinstall the portable version from scratch, it keeps hitting same error from 1st run

I have also double check the firewall and antivirus to make its not blocking All other browsers works just fine

How can I check what is being loaded on my computer with my browser Firefox when I start up Firefox. It takes too long for my homepage to load compared to other browsers. Can someone help so I can determine what is being loaded when I start up my browser Firefox? Thank you.
