new firefox update today plus windows update - get message "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." Have tried to restore - no luck. Other bookmarks - empty.

Lost all bookmarks

I was wondering if there are any fix for this glitch I am encountering in this website https://currently.att.yahoo.com/ | I get the log out successful when I try to sign in, this is site is working fine in other browsers but I want to use firefox for it.

I recently received a note from firefox tat I had done something wrong and that is why I lost y bookmark option. I em wondering what exactly it was that I did wrong. I EM IN THE PROCESS OF UPGRADING MY COMPUTER TO WINDOWS 11. I hope you can help me with this issue. If not, I will not take you with me on my new computer.

Dear Sir or Madam,

My name is Michael Staudt and I would like to get support form you in the following matter. For about one week now I get some strange, reappearing sites mentioned in my chronic – even though I have never opened these addresses in tabs myself. Please see the addresses (CAUTION PLEASE) and the screen shot attached.

and an omious new tab with the address: „http://127.0.0.1:42842/lp?u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“

I tried to search the internet for „syscsrv“ as a potential thread and I have found some entries in forums of people who seem to have the same issue. However, in the forums there were no solutions for the issue mentioned. Are these two addresses potentially dangerous/ malicious or are these potentially firefox bugs?

Thank you for your help.

Yours sincerely, Michael Staudt

When File Explorer of Windows 11 25H2 tries to access and open an icon-file in the FF (144-64bit) profile's 'shortcutcache' folder, explorer gets Access Denied. The account running Firefox has admin rights.

Looking to the ACL of the profile folder containing the folder 'shortcutcache' show no reason for the blocking. Trying this with a new profile did not help.

TWO STEP VERIFICATION AUTOMATICALLY FORCED ON ONE OF MY COMPUTERS

AND FIREFOX DOES NOT "REMEMBER" WHEN SIGNED IN EVEN THOUGH CHECKED AT SIGNIN

WHEN I VIEW MY SETTINGS,,,,TWO STEP COMES BACK AS DISABLED.....BUT THATS INACCURATE ?? HOW CAN I DISABLE THE FORCED TWOSTEM FEATURE ON THIS SINGLE COMPUTER ??

Trying to use the PWA features. Firefox 144.0 and windows 11.

Clicking the "Add to task bar" button, which makes the PWA window, but if I close the windows it removes the PWA app.

If I manually pin the PWA app to the taskbar, it just becomes a generic firefox bookmark. It seems i'm also not getting a windows pop up related to this when looking at video guides.

Unsure whats blocking it if any has seen before
