Firefox-Hilfeforum

When I cut and paste text into the chat edit window in the discord website app, the text I am pasting appears twice. This started happening within the last month. I am using Firefox 78.0.1. This does not happen in chromium, for example, nor in pasting info to other applications. I am running the latest Linux Mint OS as well.

I tried sharing my screen with audio to my friends in Discord and Google Meet, but my friends couldn't hear anything from my pc besides my mic. I tried sharing a tab in Mozilla and the entire screen, both doesn't work for me.
