My desktop icon has disappeared. It is still on the taskbar and in Start Menu (Windows10), also listed in programs on control panel. However I can not find it in Program files and have not been able to reinstall the desktop icon. Can you help me? Leslie Booth ([edited email from public support forum])

I'm 84 and know little about computers - when I try to get into e-mail it says "program running but not responding" How do I correct this? Please help. Since I can't open my e-mails you can't reach me. Phone: [edited phone# from public community support forum]

After a recent Firefox updated 11/17/2025 I went to try and use Firefox as my default browser I realized that all my bookmarks that I saved for I can't remember how long a very long time (years) I lost it all and I don't have any backups bcuz I never had to make any and now after a new update I have zero bookmarks left I am very disappointed and angry at the same time bcuz if I put so much efforts on doing something I expect to know that what I did won't just get completely erased so I just wanna get that point across Firefox was my favorite web browser now I'm not so sure anymore anyway my email address is as follows [edited email from public community support forum]

Hi,

This is the first time I have reset my PC after switching to FireFox.

As far as i was aware, I had an account that allowed syncing.

Anyhow, I've logged into what I had thought was my account, yet it is empty.

Is it possible to have multiple accounts from the same email address?

If i provide my email address, can someone check to see what the issue is?

I'm 99.999% sure I have the correct email address.

I am trying to preserve my POCKET data before it all goes away. Mozilla responded to my email requesting data but when I opened the link I got this message that "the provided token has expired : despite it being less than 24 hours. Plus a lot of other characters meaningless to me. What can I do now?

This XML file does not appear to have any style information associated with it. The document tree is shown below. <Error> ExpiredToken <Message>The provided token has expired.</Message> <Token-0>

Have an old list of bookmarks that was imported from an old pc running widows vista to a new HP machine that shows as a firefox document on the desktop, List is outdated and needs to be edited with deletion of some of the old listings but can't figure out how to do that ???? Any help appreciated. E mail ([edited email from public community support forum]) best for response. Thanks Ed Scott

I bought a new computer 7-1-25 and I wanted to contact you about problems with your update, but it rejected my Acct Key - and when I looked at the email I got with the acct key it said Windows 10 - which tells me someone hacked my old acct because I have Windows 11 as of 7-1-25!

It seems the only option to sync info between the Mac and iPhone is everything.

My Mac has Thousands!!! of bookmarks. And a long History.

I want less than a fraction of that info on my iPhone.

How can I be super-selective in what is synced?

I have lost all of my bookmarks, bookmark tool bar after Firefox's last update. I have spent the last day trying to recover what has been lost but I am having no luck in getting everything back in place. I have tirelessly gone over all your possible remedies and get no results. I can't even send a message to Mozilla through their help messaging system. My only recourse appears to start using another web browser. If I can't talk to someone who can help guide me through a mess I did not cause, then I am forced to find another company that is responsive to my problems. Call me at [edited] or write me at [edited] if you want to keep me as a user of your service. Regards Mark Hannah

I found a folder on my desktop entitled Old Firefox data. It contains a folder entitled 3h0lsis5.default-release. It's almost 900 MB. Do I need this folder? Or can I delete it? Thanks in advance.

I installed last update and all my current tabs are gone!!! Ancient ones turned up! How do I get back my tabs. Need for a book I'm working on.

Plus my history now has my individual gmail emails in it? That I do not want.

Lastly it's synced with my phone tabs, which I don't want either. This is an unwanted, new addition.

Please advise. If I go to prior version, will it fix above issues? Very upset.

Thank you.

with the new function of Tab Groups i was wondering if it is possible, or can be added in the future, to sync existing Tab Groups to all or specific devices in order to access created groups on my private Macbook to my work Windows Firefox.

thanx for any reply

I have tried all of the recommended ideas in the articles about reloading bookmarks and nothing has worked.
