No problem, I did not have a lot of a time so did not browse the other topics.
Could the default engines be unloaded from a specific .dll in the main folder?
They must be 'stored' somewhere?
I already deleted the default browser application - didn't work - it might be an app to check the browser is default but whatever its gone and FF still works without it.
Edit: I also deleted everything in the features folder (Form Autofill, DOH Rollout, and the Web-Compat junk - but these also re-enable unless you delete them)
Furthermore I could just begin to delete certain files in the main folder and see if the search engines disappear.
If I brake Firefox then I will just re-install, so I do not mind experimenting - everything is backed up.
So I might delete random stuff tomorrow and see if (by trial and error) I can hit the jackpot.... could be fun!
As for CCleaner they could just omit them because technically they are not your typical extensions - because you cannot turn them off, delete them and they do not show in the extensions section of FF but of course this kinda defeats the point - WHERE ARE THE DEFAULT SEARCH ENGINES!? lol
Cheers.
UPDATE: Partial success with editing the extensions-preferences.json, extensions.json and extensions-settings.json files all in your default profile folder.
It seems that even the slightest edit of extensions.json removes the list of engines but it also removes everything else (all but the openH264 codec thingy). My add-ons such as uBlock are still in FF but i can no longer edit them via CCleaner... so getting closer to a temporary fix!
p.s I set the above files to read-only to prevent Firefox from resetting them, though I am not sure if it does this but did not take the risk at this point.
