I installed Firefox on my new computer. It imported setting from Chrome. That's not what I wanted at all. Now, I can't get rid of that information that was imported because it synced. How do I get rid of this data permanently? I have Firefox on my old computer but I don't want to connect online for fear it will sync and contaminate my other Firefox installations. How do I clean out my online profile?

Hello, I use Firefox on two desktop computers and one mobile device. Firefox is being slow on one desktop, so I want to "refresh" it. The [page] says that extensions and search engines will be removed... but will they be restored by Firefox Sync from the other desktop computer? Or will sync also remove extensions on the other computer? Thanks

Dear Mozilla Firefox Support,

I am seeking clarification and assistance regarding saved login details that appear in my Firefox browser, both on my laptop.

The situation is as follows:

At some point in the past, I mus thave attempted to access the Plenty of Fish (POF) dating site via the app on my iPhone. Alhtough not presently active, my iCloud account shows a history of the app being downloaded, and stored in the cloud.

I do not recall ever completing an account setup or using the service, but when I check Firefox on my laptop, I can see a username and password saved under Privacy & Security settings for POF.

I am trying to understand whether these saved credentials could have been synced between my iPhone and my laptop at the time of the attempted registration, meaning that they were stored automatically even if I did not intentionally log in on my laptop.

My specific questions are:

Do the Firefox saved logins on my laptop and my iPhone interlink automatically if Firefox Sync is enabled? (i.e., would login data entered on my phone app/browser be stored in the Firefox passwords list on my laptop?)

Is it possible to determine whether the saved username/password for POF was stored via the iPhone app/browser rather than being typed directly on the laptop?

I belive that if login attempts fail due to a non-existent or corrupted username/password, Firefox still store the login attempt details (username and password) even if the login itself did not succeed, can you confirm this? Is there a way of telling which it was failed/sucessful

This is a sensitive and personal matter, and I would greatly appreciate your guidance and any clarification on how Firefox may have stored or synced these details.

Thank you for your support.

Kind regards, A

This " List all tabs" drop down icon does not exist in customize toolbar items. I am trying to open a closed tab group.

Also, I am trying to sync tab groups between computers? Can this be done?

Firefox abruptly factory reset itself after I turned my computer off and back on again. All of my themes, extensions, and bookmarks are gone. My phone, which was connected, is still normal and has my full search history+bookmarks.

How do I fix my computer?

I am moving from an old (2013) Dell PC to a brand new Windows 11 machine. All of my passwords, credit card numbers, contact info and log-in information for websites are stored in Firefox. I would like to preserve those settings when I upgrade to my new computer and do not know how to do that. Please advise.

Hi, I've been using the latest Firefox version on 2 MacBook Pros, and the bookmark favicons are lost when syncing to other devices. They remain on the host device, but are not transferred to the synced device. This is my first attempt at syncing anything in Firefox, so I don’t have any previous settings/files that could be interfering.

Also, “Tabs from other devices” in the Firefox View window lists all of the tabs grouped together, and there are hundreds in the list. How can they be grouped by window (the same way that they appear in the browser), and is there a way to have them sync directly in the windows (w/ fwd/back history in tact) so that each browser appears identically when switching from one device to another?

Thanks

Hello,

I recently got a laptop to make my work more flexible and wanted to transfer/sync my Mozilla Firefox data from my desktop PC. I logged into my Mozilla account and synced the laptop with Firefox on my desktop, but it doesn’t open the tabs that are currently open on my desktop.

My question is: is there a way to open all tabs at once, or do I have to open each one individually?

Thank you in advance for your help.

Kind regards.
