Firefox Community Forum

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.

Hi guys, Had Firefox as network default browser for decades. Now I have a problem with my DNS pihole filter, firefox just goes around it. I've read countless articles on how to stop this, I've tried DoH 0 and DoH 5, I've placed a file policies.json in a distribution folder. I've tied everything I can find on the net. Nothing and I do mean nothing, had the slightest effect. Firefox goes around whatever I try.

I've spent many, many hours on this please tell me how to kill this, I'm forced to use another browser at the moment, which is painful.

version 142.0.1 64bit W11.

Thank you Bob.

please fix.

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.

This problem, annoynace, has become overwhelming of late. It appears everytime a have a FF version download, this problem increases. Any help advice would be appreciated. Dan

I just received a toast from a sidebar app. Unsolicited notifications are the fastest way to get me to dump your app. I recommend Mozilla implement user-level control to disable notifications from sidebar apps. In theory, Mozilla is already supposed to be respecting my preferences on notifications. I have authorized notifications from only one website, and it wasn't the one for which I received this notification. There's a disconnect there.

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

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.
