big mistake, I tried to downgrade back from the latest update

more options

So, after this latest updatr.. I didn't like the settings or no how idea to change them. I thought I could just downgrade to the last version I had... I think it's 99 back to 99.0.2 from what I looked up.. Long story short I don't know how to recover anything and all my passwords and don't even know how to get into my Mozilla account now. Please have mercy as I'm not the most computer literate but im.not completely inadequate. I would really appreciate some help.

Firefox has downgrade protection that prompts you to create a new profile when you install an older version: If you try to launch a Firefox installation with a profile that was last used in a more recent version, you'll see a warning that using an older version of Firefox can corrupt profile data such as bookmarks and browsing history:

I'm guessing that happened and you clicked the [Create New Profile] button to start Firefox with a new profile. Your user data is most likely still available in the other profile so try this: 1. Update Firefox to the latest version 2. After the update, follow the instructions here: Recover user data missing after Firefox update
