User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:85.0) Gecko/20100101 Firefox/85.0

Steps to reproduce:

  1. Disable all search-engines (remove the blue ticks in this example screenshot
  2. Set browser-language from german to english or english to german
  3. click "apply and restart"

Actual results:

search-engines are reactivated in that menu from that screenshot...

Expected results:

Changing the browser-language should definitely not mess with the user's search-engine customization.

Component: Untriaged → Search

Only appears to reset the entire search-engine customization if user did not tick any single search engine:
If user only leaves "Google" entry in that list (removes all others), and ticks that one blue, this bug appears to not occur.

Component: Search → Untriaged

This only affects the one-click enable/disable, removing the engine in the UI works correctly.

Marking this as depending on bug 1650874 where we're working towards a rewrite of the search preferences UI, that may remove the separate option.

Is this the same as or related to bug 1628405?

It is very loosely related, it is a different preference stored in a different place.

It has been this way for a long time - the preference that stores this is a comma-separated list of values (

We should migrate it into the search settings and have it as a flag on the search engine object. It'd also make it better as then all the data would be stored together.
