you have removed ALL my bookmarks every time I reboot Firefox. This is intolerable!!!!!!! You have cost me 24 hours of insufferable time trying to reinstall my hundreds of bookmarks.

Hmm. We’re having trouble finding that site.

We can’t connect to the server at data.digital.costco.com.

I cannot connect with my on-line banking site. When I try, I get the message "Bad Request--Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. I am able to access the site using another browser, so there cannot be a problem with the site itself. This situation has only existed since Firefox did an update. So, the problem must lie with Firefox. If it is not fixed, then I fear that I will have to discontinue using Firefox as my online browser. Please have someone from technical support contact me. [edited email from community support forum]

I am using Dashlane for password protection. I have purchased The Nord VPN and now Nord wants to install NordPass seemingly for password protection. I don't want that so what do I do now?

I seem to have been using Firefox for so long, that I’ve forgotten some of the basics. I have two Apple systems. An M1, 2020 MacBook Pro and an Intel Mac Mini. Due to issues with the MacBook Pro I needed to reformat it and am slowly adding all my applications. When I added Firefox, logged in and entered the confirmation code and synced my settings none of my extensions appeared in the menu bar (please see the screenshot as to how they appear on the Mac Mini). So the question I have is what do I need to do to get them there on the MacBook Pro.

When I log in as admin to my wordpress website, firefox gets stuck in an endless reload loop.

Sometimes if I clear the browser history or open a private window, I can successfully log in and load a page - once. The page seems to load normally but there are 409 errors shown for many of the files in the developer tools.

If I reload the page again, it goes back to the endless loop.

This started when I installed a wordpress caching plugin, but the problem is specific to firefox, so I don't really know whether firefox or the plugin is actually responsible.

How could firefox be getting 409 errors when other browsers get normal 200 responses for the same resources?

Why is firefox triggering this reload loop, and is there a way I can stop it?

I have two Mac systems, a 2018 Intel Mac Mini, and an M1 2020 MacBook Pro, both running Sonoma 14.7.6. On the Mac Mini, Firefox opens to the familar "Recommended Stories". On the MacBook Pro Firefox opens to a long list of items I'm not the least bit interested in. How do I get the MacBook Pro back to nothing but the "Recommended Stories"? I don't want/need NHL, NFL, NBA,Television, MLB, Pro Soccer, Education, Food, Health, Parenting, etc., etc., etc.

Issue Summary: When disconnecting from a corporate Cisco AnyConnect VPN on macOS, Firefox completely loses its internet connection and throws network errors. Other browsers (Chrome, Safari, Edge) continue working perfectly on the home network. Standard troubleshooting steps—like clearing Firefox's DNS cache, changing proxy settings to "No Proxy", turning off DNS over HTTPS (DoH), and flushing system DNS—do not resolve the issue.

Root Cause: Cisco AnyConnect locks low-level socket configurations and routing rules within the active Firefox user profile (prefs.js). Even after the VPN is disconnected, Firefox remains bound to the dead corporate pipeline, a behavior that standard settings menus cannot override.

Proven Solution: The only way to clear the corrupt VPN socket locks is to completely reset the internal profile architecture:Open Firefox, type about:support into the address bar, and press Enter.Look at the top right of the page and click the "Refresh Firefox..." button. Accept the prompt. Firefox will close, securely back up your bookmarks/passwords, generate a fresh profile, and restart.Internet access will instantly return to normal. (Note: You will just need to reinstall your extensions afterward).

When I opened my Firefox browser this morning, all of my bookmarks were gone, the ones in the bookmark menu and the ones on the toolbar. I am unable to get any bookmark to save.

Here is the site I desperately need to click around on. I can't access more than the homepage via Firefox (laptop), Safari (my laptop and iPhone) or Microsoft Edge (my husband's laptop). For the links on the page, I get an error message every time. And I have disarmed as many cautionary protections as possible. Yet other people seem to be able to use the site like a roller rink.

Ideas?

Thanks.
