[Bug 1026869] Re: Firefox accepts dictionaries and spell check entries from every which spell check backend, leaving problems with defaults and the language selector enables this behavior

[Reuben Thomas]

In fact, the situation appears to be more complicated, and points to a
race condition of some sort.

Having fixed the problem, I thought I'd try a theory about what causes
it. So, I removed the dictionary and restarted Firefox. However, my
spelling language was still correctly set to en-GB.

Further, I can no longer reproduce the problem in a fresh profile, which
of course does not have the dictionary installed.

I should stress that the only thing I changed in any of this was my
Firefox profile; I did not add, remove or otherwise alter any Ubuntu
package.

Hence, I really can't see what could have fixed the problem (since it
has gone from being reproducible with a fresh profile to not being
reproducible with a fresh profile), and I wonder whether there may be a
race condition; not least, because the code that scans for dictionaries
runs asynchronously.

Bug description:
  I've been searching for the solution to this bug for a long time.

  Firefox's spell-check, despite my locale being en-US, sets itself to
  en-GB, en-ZA or something en_US, which isn't even correct.

  The problem, it seems, is that Firefox uses whatever spell-checking
  backends you have installed - aspell, myspell, and hunspell. The
  result is that Firefox chooses, en-GB as the default spell checker
  more-often than not. So I uninstalled myspell, hunspell, and a package
  called firefox-locale-en and now everything is correct - only one
  spell checker is installed in Firefox.

  The language selector, however, always prompts to reinstall these
  backends whenever it is loaded.

  This Firefox add-on can assist, it gives you a list of dictionaries
  installed: https://addons.mozilla.org/en-US/firefox/addon/dictionary-
