Today, when opening Firefox, it ran an update (to Ver. 151.0.2) and crashed. It attempted to restart, but instead ended up creating an "Old Firefox Data" folder on my desktop. How can I easily reinstall my previous setup from this data?

I have logged into TinyURL.com MANY times using Firefox. Now, I get a Cloudflare Validation Error when trying to do so (see attached screenshot/snip).

This was done in Troubleshooting mode, but is the same in standard mode, though I have no extensions enabled. I've tried turning Protection Tracking off; no luck. - We use ZoneAlarm, but the Web Secure functions are all disabled. - I have the same issue on 2 PC's, one Windows 10 and the other Windows 11, 64-bit. - I'm on FF release 150.0.2 - 64-bit, and both Windows installs are fully updated and kept that way. - I've reached out to TinyURL in hopes of resolving the issue. They suggested many of the above steps but not resolved this issue. - HOWEVER, I've found that login via Google Chrome IS seamless - no issues.

What is it with Firefox that it's having issues with the Cloudflare "Human" check? I've checked the Cloudflare site; all conditions are good, and this very setup passed the "Turnstile" check.

FF is my #1 preferred browser, so please look into this. I see that others have posted similar issues over multiple years here (but a search of support articles didn't find one . . .)

Thanks,

Hello, I have been experiencing tab crashes while watching MSNOW at 4pm eastern. These have also occurred in troubleshooting mode. I have submitted the error codes and pasted the most recent five here. I also received an error code which to the best of memory stated to possibly reinstall firefox. Any assistance would be appreciated. Regards Bruce Caress

i keep having to sign in to every website. bbc sounds, iplayer, amazon prime ITVX etc as if i using it for first time, have had many laptops and browsers inc firefox and this is first time i have had to sign in again and again and again..........can i fix this or do i have to get google chrome cos its annoying and unnecessary. thanks for your time

the resolution offered to my earlier question about removal of logo did not help and the youtube video also did not help. What am I doing wrong? Please consider me a tech 'idiot'.

Hi, I realized the other day when I went to use firefox that my bookmarks and history were all missing from firefox. I first tried to see if it was a profile issue like listed here: https://support.mozilla.org/en-US/kb/recover-lost-or-missing-bookmarks but even though it had another profile my history and bookmarks weren't in the other other profile either. Next I tried the next method on the page where it says you can go to manage bookmarks then once in your library you can click restore to fix it but it refuses to bring up any files or folders when I do this. Also the library is totally empty and there's none of the previous shortcuts that show up from your most common pages when you open the new tabs, but when I opened firefox the first time it had the tabs I was previously on when I opened it like the previous session. My computer is very old and sometimes doesn't like to open new applications but a web browser or folder is basic enough that I've never really had issues with it other than slowness.

I apologize for the stupid question and greatly appreciate your patience. Thank you very much for any help in advance.

Bonjour, Quand je suis connecté à mon compte Mozilla, je ne vois pas apparaître l’icône VPN en haut à droite, et je ne la vois pas non plus dans la personnalisation de la barre d'outil. Merci pour votre aide. Cordialement

Hello,

In Firefox (up to date), the “module” (right-click) that allows for direct translation is great, and I want to thank you for it.

However, do you plan to keep the “Windows 98-style” stamp-like format of the dialog box that opens for much longer? In 2026, on 27-inch screens, it’s honestly very annoying—even if you can zoom in just a tiny bit, it’s a pointless step and not ergonomic at all! It’s the little details like this that make us look elsewhere!

Thank you in advance for your understanding!
