Clicking links anywhere opens a new firefox browser

So I had ubuntu 20.04 and installed the budgie desktop.

Now when I open any links from slack/others it opens in a new firefox window but where im not logged in, no cookies etc. Does it mean I have two separate installations of firefox?

Check if you have the snap version of firefox installed as well as the deb version

snap list

There wasnt any in snap list but after a restart it did not happen again.
