I'm using Firefox 88.0-2 installed on Debian 10 using snap. When i try to upload any file it just doesn't show the file selection window. When i try to download any file it shows the window where it asks what you want to do with this file but doesn't download it when i select the save option. I tried changing the download location, clearing the download history, clearing the settings of firefox handles different types of files and also resetting firefox. Also firefox creates a folder 'firefox.tmp' in downloads folder on my machine. Even if delete it, it gets created again when i start firefox. Anyone else facing this issue or any idea how to tackle it ?
