Heads up on Firefox extensions - Linux

[Grumpus]

Looks like some of the items in about:config have been changed back to support storage of extensions.
This causes the loss of any data which supported the extensions.
For Privacy Badger it does not accept the storage.js file which worked with Firefox 79
Culprits to check in about:config
extensions.webextensions.ExtensionStorageIDB.enabled
You could have multiples of this one:
extensions.webextensions.ExtensionStorageIDB.migrated.extension name or number, T or False
You may also need to check : both need to be true for userChrome to work
extensions.webextensions.userScripts.enabled
toolkit.legacyUserProfileCustomizations.stylesheets

Thanks for that.

Does that mean my Privacy Badger version 2020.8.25, last updated today isn't working properly in my Firefox 82.0a1, or okay since it probably updated after 82.0a1 was released?

I haven't noticed any problems.

@WaltS48 - in updating three different systems there were differences with each one for Firefox 80.
All three systems have the same settings, same extensions and same themes.
On Linux Mint Mate 19.3 after the normal preliminary removes and setting checks, no problems but settings had been changed for extensions.
It was necessary to import the data for NoScript and there were additional data bases in the profile which had not been there before, deleted.
Linux Mint Cinnamon 19.3, after the normal preliminary removes and setting checks, no problems, apparently no changes, no additional databases.
Linux Mint Mate 2020, update from 79 made changes to the extensions storage items and other settings in about:config.
Privacy Badger would not import the storage.js settings from the previous version, gave can't open file panel, this also for the 19.3 Mate.
Still have one more older system to do the update/install but it seems the age of the Firefox may have something to do with it, long time standard settings not affected possibly.
Followed an established delete, modify format on all systems before opening Firefox.
Modifying (editing) various json files in the /usr/lib folders and in the profiles.
