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 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.

Hi everyone,

Firefox on my desktop has been crashing frequently, sometimes shortly after opening it and other times while browsing normally. There doesn't seem to be one specific website or action that consistently causes the crash.

I've already tried restarting Firefox and my computer, but the problem keeps coming back.

Has anyone experienced frequent Firefox desktop crashes recently? I'd appreciate any suggestions on what I should check first, especially regarding extensions, hardware acceleration, crash reports, or corrupted profile data.

I'm happy to provide my Firefox version, Windows version, and crash report details if needed.

Thanks in advance for any help!

I sometimes sell items on sites such as eBay. When I try to copy and paste the picture (from my Photos) is just a weird symbol. If I go to a different computer it works! If I go to a different browser it works! When I open a weather App the radar is all washed out with different colors. What's the issue?

I have used Facebook in my Firefox browser for several years. Then all of a sudden, Facebook will load, then it will not load and yesterday and today, it won't load at all. I have to go over to Chrome to get on my Facebook. Please fix whatever is preventing me from using Facebook on Firefox.

I have paid for and used Mozilla VPN for some years, The app has now disappeared from my Mac Book and when I try to reload it from the website it states "error" and will not reload.
