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.
