Question Local Backup for OPPO phone

[Fred V1]

If I, let's say, clear the app data of downloaded browsers like Firefox, will local backup on my OPPO device (or a similar backup app or any local back up of certain devices however it works) restore the session (app data) that was backed up?

I would assume that if the backup is in a different app, not related to or created by any of the browsers specifically, that whatever you do the browser apps will not affect these backups. I would go on to assume that the backups are not encrypted in any special way that once the browser was reset it couldn't recognize a backup for the same app and restore it.

I asked Google and Gemini agrees,

Yes, it's generally possible to reset a browser app and still recover a backup, especially if you've been using cloud synchronization or have backed up your browser data to a file. After resetting, you can often restore your data by signing back into your account or restoring the backup file. [1, 2]

Google Search

Not sure what else we can say or do, really you'll just have to try it, maybe on the browser you care the least about, and see for yourself.

Best wishes and good luck.
