All downloads on firefox open as "file://" links
I am currently using Ubuntu 24.04. I recently switched from the snap ubuntu package to using the firefox APT package. However, I've noticed this really weird issue. Whenever I download a file, it always seems to have the "file://" link or mime type.
Say for example I download an mp4 video, trying to open it via firefox results in a dialog asking me to "select which application i want to open this file link in"
I have tried refreshing firefox, and tried completely removing it from my operating system (a search of my entirety of / showed no traces of anything relating to firefox), but even after a clean install, the issue persisted.
The only way I found that can fix this issue is by using firefox nightly, or using the firefox flatpak. And I'd prefer to not use either.
I was monitoring the browser console, and upon clicking on the file in the downloads list, It seems that firefox gets this error:
Uncaught (in promise) TypeError: defaultButton is undefined
_setInitialFocusIfNeeded chrome://global/content/elements/dialog.js:318 _postLoadInit chrome://global/content/elements/dialog.js:332 connectedCallback chrome://global/content/elements/dialog.js:149
dialog.js:318:9
This error does not occur on firefox nightly.
I believe I have troubleshooted this as much as possible on my end, and I'm unsure of what to do about this. Could I please get a bit of help?
