Firefox Support Forum

Have used Firefox for decades and suddenly it is having problems. If I surf around and have a few tabs open, some of them might crash. Firefox tries to restore them and sometimes it works and sometimes they just crash again immediately. I can go to Amazon and the page won't load completely so I can't do anything. If I try and close Firefox it won't close, it is frozen. And often, pages just load very slowly even though my internet connection is strong. This just started about a month or so ago. I have refreshed Firefox, updated it, and checked the systems on my computer. All my internal diagnostics returned "no issues." So it has to be the program.

When downloading a file in Facebook Messenger, Firefox changes file extension to .pdf. My case was .docx file but looking for help found people have problem with other formats, even non document saving as .pdf.

Not asking for help, just reporting problem

I was able to use it normally before, but when I downloaded a file, the browser froze, so I used Task Manager to terminate Firefox and reopened it, and then I encountered this situation.

When I open the "Downloads" in Firefox, the browser hangs and prompts unresponsive. I have tried the troubleshooting mode, but it did not work, the problem still exists. I also tried to "Refresh Firefox", but this did not solve the problem either. I also tried to delete places.sqlite, but it was also ineffective. Then I created a new user profile, but the same situation occurred. I also tried to uninstall Firefox, delete AppData/Local/Mozilla and AppData/Roaming/Mozilla, and then reinstall it, but it also couldn't solve this problem. I've had this problem on both 126 and 125.
