Me too. Firefox 95.0.2 in Mate fully updated. I have had this problem
before but it always sorted itself out later.

Hi all,
After the recent upgrade of Firefox (and Thunderbird) in oldoldstable
(Mate desktop), Firefox always asks me to be default browser, even
though I have set it as default in Mate's default applications, and
respond to that asking by click on 'dont ask me again'.
Furthermore, Thunderbird is also set as a default email client.
However, if I click on a weblink in Thunderbird mail, another
Thunderbird session opens (instead opening Firefox). And when I close
both software, and return to Mate control panel to check again for
default applications ... voila ... Thunderbird seems as magically
selected for both mail client and web browser there!
How to prevent that misbehaviour? All worked well with previous
versions of Firefox and Thunderbird. What went wrong with new versions?
