Forgetting Addons

[BWille]

Hi,

I am running Mozilla 122.0.1, british englisch 64bit Linux under Mint 21.3 Cinnamon. Since the last version it "forgets" installed Addons like Ecosia or Zotero Connector or Inoreader. Some addons like Bitwarden or Cookie Autodelete are retained.

I cannot imagine a likely mistake on my part. Any hints?

Like you I cannot install Zotero connector on Firefox and have been obliged to use Chrome.
