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.

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.

The welcome addition of Tab Groups I just noticed on updating my Firefox, however looking through help and documentation, it's not clear to me if Tab Groups syncrhonise across devices (or at least desktop devices) as like recently added to Chrome. Wished to check if this is case

My Macbook Pro's Firefox has a convenient bookmark toolbar, my Mac Air's FireFox does not. Can I find a setting on the latter to restore my settings from the former?

Hi,

Today when I powered on my pc and opened up firefox all tabs were lost.

I have the option to retain tabs when opened up enabled.

I could not find them anywhere, so I had to search opened tabs from the other synced devices and click on each of them, and create again all the tab groups.

This is a big problem if randomly all the tabs can get lost, am I doing something wrong?

Another thing : I thought that when I create groups of tabs, and save them I coul retrieve them across all my synced devices, but the other devices can not see those groups, is this a normal behaviour?

Thank you

How do I automatically open all current Firefox tabs from one laptop onto a new computer? I just set-up Firefox app on a new laptop computer, and want to automatically reopen all the tabs that I have open on the old computer onto the new one?

How do I do this without going individual tab by tab?

Thank you for your help.
