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. ** Bug watch added: Mozilla Bugzilla #1489820 https://bugzilla.mozilla.org/show_bug.cgi?id=1489820 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1791789 Title: FF62 upgrade : search engines override, french dictionnary and language pack lost.
