Everything I Try To Download Fails

more options

I've not been able to download anything on Firefox for about 3-4 weeks now. Every time I try to it immediately fails with no explanation given. The only type of download that works is "Save Image As..." Even trying to download a picture with a download button instead of right clicking nets an immediate fail. I feel like I've done everything to try and troubleshoot it myself, but nothing seems to be working.

I've restarted my computer, ran Firefox in troubleshoot mode, refreshed and reinstalled it, checked for viruses and malware, tried both nightly and ESR versions, tried running them as admin, logged out of my Firefox profile, cleared my cookies and cache, changed and reset the download folder, ran a repair for Visual C++, and reset my windows security settings. I'm honestly surprised nothing has worked.

The only thing that I know I haven't tried yet it refreshing my entire computer, but that's my very far last resort because I'm able to download files just fine on Microsoft Edge. Only the Firefox applications have given me any problems, so if I were to refresh my computer and have the problem still not be solved somehow I'd be deleting everything to get nowhere.

If anyone has any other ideas to try that be very much appreciated.

I solved my problem! I ended up reinstalling windows to try and solve a different issue I was having and that ended up fixing Firefox. I still don't know what the original cause was, but I can download files again.

This sounds very similar to https://bugzilla.mozilla.org/show_bug.cgi?id=1900521 - could you check the permissions on your "Temp" folder, and if they do not allow you write access, does giving your Windows user account write access resolve the issue?

My system, admin, and my user account still have write permissions. I also recently used the TAKEOWN command on my entire drive so I thought that might've given it to me, but it unfortunately still hasn't solved the issue.
