I use Ubuntu 21.10 Linux, Mate Desktop, and Firefox web browser. I have eight workspaces and have Firefox in the 2nd. However today it started following me to whatever workspace I switch to covering up what I'm trying to access. I thought maybe it was the upgrade to 96.0.1, so backed out to 96.0.0, but still the same behavior.

I wasn't sure if it was Firefox or Mate that got hosed, so I tried Chrome. Chrome stays put but all my passwords, bookmarks, etc, are in Firefox. Anybody know how to make Firefox stay anchored to one workspace?
