I have Firefox installed on a Windows 11 desktop. The profile is missing, yet Firefox is working fine, and I see all of my bookmarks, etc.

I have windows set to show hidden files.

When I try to run %APPDATA%\Mozilla\Firefox\Profiles\ it tells me that the location is unavailable.

I cannot find the profile anywhere in file explorer, despite multiple tries to search for it.

If I go to Help > Troubleshooting Information, I see a "Location is not available" message, shown in the attached image.

I could uninstall and reinstall Firefox, but I'd prefer to solve this because the exact same thing is happening to my Thunderbird profile. It doesn't exist anywhere, yet I can see all of my emails and it appears to be working properly. I only found this problem because I wanted to backup my emails but was unable to.

Both of these profiles must exist somewhere, but I've tried everything to find them. Please help me fix this in Firefox, and then if I have a fix here I'll try to apply it to Thunderbird, where I have a lot of emails I'd hate to lose.

I requested my Pocket export three times in June '25 and have received nothing. (Most recent request on 24th June '25, ID: 25174602-3e81-421e-a30d-71ff91dd2d66

I have also contacted Mozilla Support using the contact form twice to raise this issue and didn't receive any confirmation of those support requests to my email address.

The only possible explanation that I can think of is that maybe there has been a problem at the time when Mozilla acquired Pocket and I linked my Pocket account with my Mozilla account. I had previously used a different email address for my Pocket account prior to 2017. I currently have two email addresses (primary and secondary) associated with my Mozilla account but none of these email addresses are showing up in my Pocket settings, only my username. My Mozilla account is the only place where I can see my email addresses listed in my account details but I can't understand why I didn't get the confirmation emails to my Mozilla Support requests.

I used Pocket extensively for work so I really need to get the export. I'd really appreciate some help, thank you.

My windows10 laptop was destroyed, but I was able to retrieve the hard drive with all data in tack. I am currently using a new laptop loaded with Windows 11. I've been trying to find the bookmarks on my old hard drive to copy on a usb to reload on my new laptop with no success. HELP

Following a restart, Firefox has installed this icon on my desktop: "Linguistic handbook feeds backup.opml", with the Firefox picture.

All it does it is take one to a browser page opening the file on my C drive, and saying blankly: Firefox Live Bookmarks. (Incidentally I cannot see this file listed anywhere under Mozilla in Programs or Programs , so I suppose it is nested in something else.)

I assume I can delete this without damaging Firefox for all eternity, but I am curious to know how it got onto my desktop.

I assume the "linguistic handbook" is not actually what it says but something to do with the many languages Firefox is translated into, yes ? - or does it really deal with catenatives, anaphora, kernel clauses, retorts (et al.) used as a test of auxiliary status, or whatever ?

hi. i used only Firefox from Mozilla. can i delete this folder safetly? ~/library/application support/mozilla/native messaging host/com.apple.passwordmanager.json

How can I backup bookmarks saved in folders on the bookmarks toolbar? I want to keep the bookmarks in their respective folders. When I attempted to back up bookmarks they were all just dumped out into one large list, essentially a large pile that is no longer usefully organized.

After a problem with his Internet connection, a friend is now unable to open Firefox. At first the message was that ‘… this tag has crashed.’ Now the message is that it cannot find something with a .dll at the end. I suggested to simply uninstall and then reinstall Firefox, which would also ensure that he has the latest version. However, he has no backup of his bookmarks.

I was, therefore, wondering whether it is possible to access the bookmarks somewhere else on the computer, in order to back them up before the uninstall/reinstall procedure.

Many thanks.
