Using your browser for first time today using two popular websites that are used daily (theglobeandmail.com and theweathernetwork.com) that Malwarebytes deemed these unsafe quoting 192.178.192.132.443 - they are now blocked and don't understand why these websites would have any problems. Can your team help rectify this problem please. E. Scholten [redacted email from community support forum]

Firefox becomes noticeably slower after I have been using it for some time. Pages may take longer to load, tabs sometimes become unresponsive for a few seconds, and switching between multiple tabs can feel delayed.

I have already tried restarting Firefox and closing unnecessary tabs, but the issue can return after continued use. I would like to know what could be causing this performance problem and which troubleshooting steps I should try.

Could extensions, cached data, memory usage, or hardware acceleration be responsible? What Firefox settings or diagnostic information should I check to identify the cause?

Unable to load https://fingtrainer.com as of yesterday. Been downloading the flingtrainer for single player games for a long time now and there is no issue. Try to disable/change enhanced tacking, dns, site were included in exceptions and reinstalling firefox does nothing. While the learn more link provide image solutions, none of them does anything and the disable button for the enhanced tracking is not working. Other browser like opera gx is able to load without any issue. Please assist with a solution or kindly revert the settings.

Server Not Found

Firefox can’t connect to the server at flingtrainer.com. Did you mean to go to www.flingtrainer.com? What can you do about it?

   Check to make sure you’ve typed the website address correctly and try again in a few moments.
   Check your network connection.
   Check that Firefox has permission to access the web (you might be connected but behind a firewall).

I have used Firefox for years. Have a backup computer that has Windows 10. It defaults to Bing. I hate Bing! VERY much want to use Firefox for Windows 10. Please, if you can, just email me a link to download Firefox that will work on Windows 10. That is all that I need. My two email addresses are: [edited] OR [edited from community support forum]. Either address will work (both are for same account). Thank you so much for your help! LOVE Firefox!

I have webpage (Home Assistant instance) on my local network on which I would like to use microphone (for Assistant functionality). Page is completely local, i.e. not visible from Internet. My issue is I can't force Firefox to allow microphone access on this page. I've tried messing with media.devices.insecure.enabled config, but it didn't help. Is there any way to add such page to some whitelist to allow microphone access? From what I gathered Chromium-based browser provides "--unsafely-treat-insecure-origin-as-secure=..." option but I didn't find anything similar for Firefox. I know I could expose my server to outside network and get SSL certificate (from Lets Encrypt) to make it work, but exposing server to Internet just to get local microphone access somehow doesn't feel like a more secure solution. I could probably also issue self-singed certificate but dealing with that also seems at least annoying.

My Firefox created a new profile and reset everything. I was able to go back and locate my bookmarks and restore them, but my menu bar is reset, my history and saved passwords etc are all gone.

Firefox version: 153.0.4 / Windows 11 25H2 26200.9168

Attached are images showing the performance settings and the active extensions in case any of them proves to be responsible for the problem.

Yesterday I noticed a horizontal screen tear when scrolling down through sites like X(Twitter), YouTube, GMail, Reddit etc. I immediately checked my performance options and they were deselected. I activated them again, but this did not solve the problem, I also tried to active some layers in about:config but those were already activated. Checked Nvidia settings too, vsync is on, Edge is not affected, Chrome is not affected, even installed Waterfox to see if only Firefox-based browsers are affected, but that one was OK too.

Last resort was to refresh the Firefox installation from the uninstall utility. After the refresh and all settings/extensions got auto-reinstalled, the screen tear got fixed. I left the PC running over night and when I accessed Firefox again this morning, the screen tear problem was back. However, now, the performance options are disabled, and if I try to enable them and restart Firefox, the options get disabled again.

Would really appreciate it if anyone could provide a solution that does not involve refreshing Firefox daily.

the password logins are confusing.disturbing and stifling my project,i need to log in to Carprog Online but your password page wont allow me therefore delaying my time in

I can't download some pdfs, notably my bank statements. I CAN download some pdfs. Eg, I can download my car manual (although it's a process of downloading it to my Google Drive). However, trying to download my bank statements, Firefox gives me no options at all, and, indeed, I get an error message. Yet I CAN download my bank statements using Google Chrome! I've carefully checked all my Firefox settings, but nothing seems to address this problem. I've spoken to my bank, and they don't know why I can't download them either. When I try to download the statements, I get a screen saying it can't give me a 'Preview' (see attached screenshot), but there's a 'Download button. When I click that I get a white screen with the 'error' message:

"No API key found in request. request_id: d52e0732a3d10a75b1ec58534845c15c"

(2nd attached screenshot.)

I have asked about this before on this forum, but to no avail.

YouTube videos are playing choppily in Firefox. The video frequently stutters/freezes or does not play smoothly, even when the same videos work normally in another browser. I have restarted Firefox and my device, but the problem continues. I would like help identifying whether the cause is hardware acceleration, Firefox extensions, graphics drivers, or another Firefox setting, and I would appreciate step-by-step troubleshooting instructions.

Please provide clear, step-by-step troubleshooting instructions to identify the cause of the problem and explain how to fix it. If possible, include the Firefox settings I should check and any tests I can perform to determine whether extensions, hardware acceleration, graphics drivers, or network settings are responsible.
