I recently turned on an old computer that I hadn't used in a while which had Firefox on it and was still logged in to my Mozilla account (but it was locked out of the account and needed me to manually log in again to access all the features). Before I did so I wanted to clear the old bookmarks on my old computer's Firefox so these wouldn't get added to my Mozilla account when I synchronized it, so I deleted them thinking only the bookmarks on my old computer's old Firefox would be deleted. But when I went on my laptop's Firefox to synchronize and make sure my Mozilla account was up to date all of my bookmarks were gone on this device as well, and now I can't seem to get them back - is there any way to retrieve these just deleted bookmarks? They took years to add, from many websites that I don't know the names of, and upon which I completely relied on the bookmarks to use.

Although I have disabled all relevant "sync" settings in Firefox, the browser is still syncing tabs across my MacBookAir and my iMac.

To make matters worse, tabs in Chrome and Safari sync to Firefox tabs across devices as well. The sync occurs in both directions.

I am not logged into Chrome or my gmail account.

Specs: MacBookAir: early 2015/ OS v. 12.7 (Monterey) iMac: Retina 4K, 21.5-inch, 2017 / OS 12.6.8 (Monterey)

Things I've tried:

• Turning off syncing in Firefox on both devices.
• Signing out of Firefox from both devices.
• Disabling "sync open tabs" via Firefox preferences
• Renaming devices from within Firefox Sync. (The name always reverts to the previous one.)
• Reinstalling Firefox
• Deleting cache from both Firefox and Chrome.
• Restarting

Images are from toolbar on iMac when Firefox is open on both computers. Any help would be most appreciated! Thanks!

I want to be able to close Firefox and have all cookies and site data removed - but I want to keep my history.

Checking the box to do just this in 'Privacy & Security' will delete cookies when I close Firefox - but all the site data remains. Under 'History' I have 'use custom settings' enabled, as well as 'remember browsing and download history'. I've tried various permutations of this, but can't get it to do what Firefox says it will.

Being able to do this is one of the main reason I want to use Firefox, but it doesn't seem to work. I have to manually delete both cookies and site data.

Any suggestions to try to delete cookies and site data when Firefox closes, but remember history?

All of a sudden when I go into Firefox and type in the web browser it comes up on left hand side of the screen and is so small that it is impossible to read. It has never done this before

I would like to stop the default behavior of firefox displaying in the tab that contains my GMail how many unread GMail messages there are -- in other words to delete "(9)" from the attached photo and never have the count displayed -- if it could instead simply say "Inbox - xxx@gmail.com"

I've just downloaded the latest Firefox version and it won't load my Cornell email - adfs.ad.cornell.edu. I'm using a Macbook Pro. I can download the website on my iPhone.How do I get my email back?

Hi,

I am using the Firefox Multi-Account Containers addon with Firefox 116.0.2 (on apple silicon). I use the containers to isolate sessions from different websites. I have a container for my Instagram session. However, when I open a private browsing window and go to instagram, I find that I am already logged in. I thought private browsing windows were completely new and blank.

How is it possible that my instagram session is available in private browsing?

Thanks in advance

Because of my work I have to use a specific car rental company but recently I am unable to log in to my account on their website via Firefox. Safari, which I prefer not to use, is no problem but if I try to log in using Firefox it gets stalled on the spinning wheel. I have an ad blocked but I had already turned it off for accessing that particular site, I think I just got a browser update, it just doesn't want to log in. Anyone have any ideas? I'm on a Macbook, OS 12.4. Firefox says it's up to date, version 102.0.1

For some reason, many homepages looks wrong when I'm using firefox from my laptop (mac). I don't know why and can't find any ways to make it better. Can anyone help me?

Here's a photo showing the wrong looks at www.saluki.se

I have two profiles on one computer and I want to use these profiles in different languages for web pages (one in English and one in my native language). If I sign-in the two profiles using one common Firefox account, this seems to be impossible: a change of the language setting in one profile immediately reflects into the other profile. Is there a way to disable the sync of language? I want histories and bookmarks to be synced across the profiles and thus I want to use the same account. Thank you.

Dear help team,

First of all, thank you for your efforts to help this community. I've been using Firefox for about a decade and this is my first question, I believe.

I recently got a new Macbook. I've installed Firefox to it (my primary browser) and want to sync Firefox to it. I have Firefox on my iMac and my iPhone. However, my password is from 2014 and I can't seem to remember it no matter how many times I try. If I choose a new password, it gives me a warning that I will lose my account information, including my bookmarks, add-ons, history, etc. I really don't want to lose that info! I have spent a long time personalizing my Firefox.

Pleeeease tell me there's some other way to sync Firefox to my new laptop (when I can't remember my super old password).

Thanks in advance for your help! Best, Jason

After installing the addon FoxyProxy and Wappalyzer , its ui language was broken! if i copy those text form the ui and paste it anywhere it shows the correct text. other extensions dosn't have that problem. How to fix this?

I'm not entirely sure what's happened, but I can describe it. My Macbook Air crashed for reasons unknown, and upon rebooting it, I attempted to open Firefox, but was met with the message "A copy of firefox is already open". I found some old guide on using Terminal to discover two different profiles for Firefox. After restarting my computer, I accessed my Firefox tabs from before, but now when I open links from my email account, they default to opening up a new Firefox window, one where it seems my bookmarks don't exist. How do I remove the second profile without losing my bookmarks?

Hi there. I'm using Firefox on a windows and linux laptop with the same settings and version (98.02). On windows the Autofill Credit Cards settings show up, but on linux they don't. I already checked this question https://support.mozilla.org/en-US/questions/1305626 and applied all settings in about:config that were suggested there. I have no clue, why the two operating systems differ in that way.

Many of my bookmarks are corrupted. They point to other websites, not the bookmarked one. Has anyone else had this problem? Is there a fix? Thanks for any info/advice. George
