HI, could your security software be blocking anything ?

Have you tried Firefox in Safe Mode ?

In Firefox Safe mode these changes are effective:

  • all extensions are disabled (about:addons)
  • default theme is used (no persona)
  • userChrome.css and userContent.css are ignored (chrome folder)
  • default toolbar layout is used (file: localstore-safe.rdf)
  • Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
  • hardware acceleration is disabled (Options > Advanced > General)
  • plugins are not affected
  • preferences are not affected

TEST''''is issue still there ?

As the next step will possibly be a Refresh.

With a Legacy extension this message would suggest that the extension's XPI file needs to be unpacked. I don't know whether this still applies to WebExtensions. Dictionaries are another example of a file that needs to be unpacked.
