FF62 upgrade : search engines override, french dictionnary and language pack lost.

Illustration ( gif )

Status changed to 'Confirmed' because the bug affects multiple users.

Hi!

On my 16.04.1, only the French dictionary got lost.

It is not limited to just French dictionaries.
All additional dictionaries I had (English (GB), Dutch (NL) and French) are no longer present after the update, just English (US) remains.

Reinstalling the Hunspell libraries did not solve the issue.

I do not see the same behaviour with the language packs though, they are still there and have been updated nicely.

Search engines do not come back either, only once after the update. Could it be that this happened to you because you manually (re)installed the language pack?

I've got the same behavior under 16.04

« Reinstalling the Hunspell libraries did not solve the issue »

I only had to take care once regarding dictionary and language pack to fix that part of issue.

Whereas whatever I try about search engines list is always « reset » and reordered to a default state I don't like at each re-launch.

The search engines that always come back are located in :

/usr/lib/firefox/distribution/searchplugins/locale/

sub-folders fr and en-*

They are

- amazon.fr|com ( yes, both )
- duckduckgo.fr
- google.fr

Our custom search engines reappearing between search engine cache rebuilds is not a new issue, but it's being made worse by a new bug (https://bugzilla.mozilla.org/show_bug.cgi?id=1489820) which is causing a cache rebuild to happen on every restart rather than after app upgrades (and is also responsible for making some en-US search engines appear for non en-US users).

I've found some other issues with our search defaults as well. I'll have some updates for this tomorrow.

And the dictionary problem is a regression from https://hg.mozilla.org/mozilla-central/rev/8810007550b1

Thanks for explanations and your time !

I believe that Firefox is using the Hunspell system libraries for the dictionaries, so there should not be a need to install the individual dictionary add-ons separately.

Please correct me if I'm wrong.

  * Fix LP: #1791789: Mark distribution search engines as read-only, so that

This should be fixed now. Some of you may still have duplicate Amazon engines enabled after the upgrade (a US one and a locale-specific one). You can remove the duplicate one manually, but we may push out a further update to do this automatically if we can come up with a way to do that which isn't too risky.

I can confirm that the dictionaries are back again, using the Hunspell libraries, and no need to have them installed as separate add-ons.

The search engines did not come back again either.

Is the problem back ? Or is it a wrong setting on my system ?
