Firefox Community Forum

It is about Master Password. Before the updates, users need to enter the password before they can continue using Firefox. After several updates it turns into Primary Password which doesn't work the way before. It now allows user to close the password input box and they can continue using the browser. I found this out after my nephew uses my PC and he uses Firefox and I noticed he was able to gain access on my browser. Lots of opened Tabs has been closed out. How can I bring back the old Master Password function which allows you to basically lock your Firefox? The new function Primary Password is a downgrade security feature.

When I try to login to Facebook I can't and a screen appears with

"Sorry! Something went wrong :(

This happens even in Troubleshooting Mode …

Exactly the same issue with DuckDuckGo browser but no difficulties with Safari where I can login to Facebook as usual …

I apologize for repeating the question, but I wanted to write about the system requirements for the computer. Where can I find this information, and if something has changed, what are the system requirements for the computer?

I just replaced my Win 10 desktop with a new Win 11 desktop. I downloaded Firefox OK, but my bookmarks are no longer there, of course. I was told that there was some way to recover them to this machine, but I didn't get any details how. In fact, the person implied they would just appear when I downloaded Firefox to the new machine. Of course, this didn't happen. Firefox did appear to recognize me (got a "welcome back, by the way" message near the top of the page). Can I somehow recover my old bookmarks to this machine?

Please create a new version of the browser app that supports the ability to use FileSystemAPI on directories, this is essential for working with a BeatBuddy project and SD cards that are saved on my computer using the online editor.

This morning (08/28/25), I updated my browser to v142.0.1 (64-bit), and Facebook as well as other sites have been affected to the point that I can't even see contents now!!!!!!!

I (God forbid) opened the same sites in Edge, and there's no problem viewing them on Edge.

Is there a way that I can roll back this latest update, because I had no problems until this morning. I'm running a Win 10 Pro OS.

The master password really needs a timeout setting unknown to me my computer was hacked I fell asleep with my Firefox browser open and they logged into my bank account the only reason I caught it was because I got a email stating I had logged in my bank account I was lucky I caught it fast and changed my bank password and removed the virus. Yes I know I should of logged off but I got side tracked and fell asleep. The timeout option on password managers are universal except for the Firefox password manager.

Hello Mozilla Support Team,

I recently noticed a file named Newtab@mozilla.org.xpi on my system and wanted to confirm its purpose. My Firefox browser is working normally, and I have not observed any suspicious behavior, but I want to make sure this file is legitimate and part of Firefox’s features.

Could you please clarify if this file is a standard component of Firefox, especially related to the new tab page functionality?

Thank you for your help!

Best regards.

Mozilla Firefox began to crash all the time; crashes happen almost every ten minutes, and it happens with every site. It still lasts about for several weeks. I tried to reinstall Firefox; I updated my drivers for my computer; I cleared cash and history in the settings; I tried to delete some files from Firefox's folder. All these things did not help. The crashes may happen with any site, and it can happen any time. I have no problem with memory shortage. My system consists of Ryzen 7 5800x, Radeon RX 7800 XT and G.Skill Flare X (for AMD) DDR4 2x16Gb.

I AM SENDING TWO SCREENSHOTS IN ORDER FOR YOU TO SEE WHY I AM SAYING GOOD BYE TO FIREFOX OVER 4000 OF RESOURCES AS YOU CAN SEE AND FIREFOX HAD 4 TABS OPEN ALL OF THEN JUST OPENED UP SO THEY WERE NOT YET CONNECTED TO ANY WEBPAGE.

I CANNOT SPEND HOURS TRYING TO FIX THIS

SO I AM MOVING TO ANOTHER BROWSER

I JUST WANTED TO SAY CIAO

Trying to redeem an Amazon Gift card to my Amazon account and it is asking me for my PIN for Firefox/Mozilla which I don't have...won't take my password or my Microsoft PIN. Now what?
