File upload functionality in Firefox doesn't work properly

My System data:

I'm using Firefox as my main and default browser. The problem is that the uploading functionality stops working after some time. When I reinstall Firefox, it works properly for a while, allowing me to upload files or photos. However, after some time, it stops working for an unknown reason. When I click a button to open the file selection interface, it simply doesn't open. I need to fully uninstall and reinstall Firefox again, which is extremely annoying.

I want to know the real problem to avoid it and not have to reinstall the browser. It happens every 20 to 30 days.
