Dear Mozilla Geeks—

As practically every other Firefox user, my bookmarks evolved into a lengthy file system that uses folders to segregate categories of bookmarks.

That is, it used to have this feature.

After the last update all or most of the bookmarks (I can't tell by scrolling down the long list) are devoid of their organizing folders. This puts a great deal of information beyond easy reach. In Mozilla Help topics one is advised to click on the library icon in the toolbar ... only there is no such icon on my copy of Developer's Edition.

Can someone suggest a method or methods to recover the folders?

Some passwords have been lost as well.

Yours Sincerely,

Glen

Firefox randomly crashes – JSON file keeps reappearing

Hi everyone, I've been experiencing a persistent issue where my Firefox (Windows 10) randomly crashes or closes. I recently noticed that this always happens when a JSON file appears in the following directory: C:\Program Files\Mozilla Firefox\distribution The strange thing is that this file shouldn't even be there, as this is my personal computer and it is not managed by any organization. I have already tried deleting or renaming the file, but after a seemingly random period, it gets recreated automatically. Here’s what I have tried so far, without success: - Deleting/renaming the file - Checking the registry at HKEY_LOCAL_MACHINE\Software\Policies\Mozilla\Firefox (but the "Mozilla" folder does not exist there) - I have never used any third-party antivirus software (only Windows Defender) Does anyone have an idea where this file might be coming from or how I can prevent it from being recreated? I’m not very tech-savvy, so I would greatly appreciate simple explanations or step-by-step instructions. Thanks in advance for any help!

I have just opened MS Teams on my Firefox 137.0 on my WIndows 11 and I get a blank screen. NOthing happens. I see that by looking in Edge the format of MS Teams layout has completely changed. I imagine that there's a setting to change to enable teams to work but how can I find it?

Export logins (passwords) creates a csv file that can't be password protected

I am evaluating a password manager application and exported my FF passwords and imported them into the app. For testing I removed all of the passwords from FF. I want to password protect the csv file rather than delete it in case I need to import the passwords back into FF. When I go to File/Info, the "Protect Workbook" option is greyed out. When I go to the "Review" tab, the option to "Protect Workbook" is available, not the "Unprotect" option, so the workbook is not protected. If I click on the "Share" folder on the right side of the ribbon, there is no "More" option. In Windows Explorer the file is on my desktop, not OneDrive - Personal. I right clicked on the file, selected "Give access to" and took the option to remove access. The File/Info option is still greyed out. How can I password protect this file or how can I export it in a format that can be imported later?

I have a laptop that died last week. I just got onto a new device, and would like to restore my Firefox settings from that previous device. So, I downloaded firefox, signed in to sync my bookmarks and extensions... and the old device does not appear in my synced devices list. Is there anything I can do to recover my account data? I know it was synced as recently as a few days ago. The device is completely bricked and I will not be able to log in on it anymore. Is there anything to be done?

Opening the Firefox window

When I first open Firefox from the icon in my taskbar the opening window says the following:

'Unable to connect Firefox can’t establish a connection to the server at 0.0.0.4. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.'

However this is only the first window, after that I can open a new tab in the same window without any problems.

I have uninstalled and reinstalled Firefox without avail. Can anyone help please?

My webmail is not loading. https://webmail.everyone.net/#/login It keeps spinning and never loads (so I can see the boxes to put in my u/p).

  • I've deleted the cookies and cache but that doesn't solve the problem.
  • I always keep current with FF updates.
  • The problem is only on my computer. No problem on my husband's computer.
  • No problem in Edge or Chrome.

What next?

All my other browsers work fine but since April 4, 2025 Firefox won’t work at all. Websites won’t load. I have tried to clear my cache & cookies, I have checked my connection settings, I have checked for malware, I have turned off all my extensions and I have completely restarted my computer several times now, nothing has worked. I also did trouble shoot mode & reinstalled Firefox (though I will admit I maybe didn’t do this step properly). I refreshed Firefox. Why is it not working? What happened? I don’t know what to do as I don’t want to lose all my bookmarks and passwords that I have yet to move over to my password manager. Please help.
