Good to remove all extension preferences on uninstall?

Unread post by moonbat » 2021-06-12, 03:10

Is this a good practice?
I've added a cleanup routine to my extensions by hooking into AddonManager.jsm so that if uninstallation is confirmed it will delete its own preferences. On the one hand, good to clean up and reduce clutter in about:config. On the other hand, in case the user reinstalls the extension, their settings will remain as they are (an example is when you replace DownThemAll with its fork GetEmAll - since it uses the same preferences, all your settings and download history continue as they are).

Depends. Sometimes it is trivial just a pref or two I'd leave it but if it were like a dozen or more you could serialize it to json or something and shove it in a profile folder and just leave a lastVersion pref in there and then expand it back out if they reinstall it. Sort of what ABPrime does.

Really it is up to you but I can say with absolute certainly it is a solid.. Maybe.
