I have 3 computers (2 desktops, 1 laptop). I want to permanently delete approx 300 unused/unneeded passwords. I deleted them from computer #1, then logged out of Firefox. The new count was 346 passwords.

I went to the second computer, deleted approx the same number from computer #2. The new count was 324 passwords I returned to computer # 1 and logged back into Firefox.

Within a short time, computer #1 is at 759 passwords, and computer 2 is at 691 passwords.

How do I get the deletions to be permanent? It's the second pass at doing this and I'm FRUSTRATED.

I logged into my account on my mobile browser, and was able to see all my passwords and saved data that I had on my computer. I ended up signing by accident and when I logged back in all my passwords and bookmarks where gone. How can I restore them??

Many questions and answers I see regarding the sync function. I would like to know the depth of what Firefox does. I have multiple PC's and an Android. What is the depth of sync for extensions? Is it possible to have mirror images of the entire Firefox setup duplicated? It would be spectacular to move from one PC to the other and find that Firefox has the exact same setup.

I sync Firefox between my desktop and Android. After I set up the syncing, I updated the login credentials for all of the websites I visit. I did this through my desktop. When I check my saved passwords on my Android, it shows all of the updated credentials. However, it also shows credentials that I had deleted. I do not show the outdated credentials on my desktop.

I tried uninstalling Firefox on my Android, restarting the device, then reinstalling it, but the problem persists. I could go through the credentials one-by-one, but that's literally hundreds of credentials to sort through, which would take a long time.

Any idea what's wrong and how to fix it?
