Firefox Community Forum

I enjoy Firefox and use it on all platforms. In the last week it has been difficult to browse if I leave the app for more than a few seconds. I have found that in Task manager, the Firefox processes go to efficiency mode. Once that happens I cannot bring the browser back active. How can I turn off efficiency mode for Firefox? Thanks.

Hello! Yesterday (03/16/2025) I received a message that the ChatZilla add-on to Firefox will be disabled on the next restart of FireFox. The message indicates that the extension could not be "verified".

I am using a VERY old computer for ChatZilla only: Windows XP Firefox 48.0.2 ChatZilla 0.9.92

I don't care about the age and inability to update any of the software, but I need to continue to use ChatZilla on this platform.

I have used ChatZilla on this machine for a very long time and do need to continue. Is there any way that I can make this work without having ChatZilla automatically disabled at the next restart of Firefox?

I used to be able to make my own settings in Bing, but since the last update my settings are no longer stored. Each time I change them, when I open a new tab the BIng defaults are used. How do I get Firefox to accept my Bing preferences?

I've been attempting to test a game project on Firefox (my main browser), but when I connect a controller, the inputs get jumbled and are incomplete, compared to the inputs working on other browsers fine such as Chrome.

Specs: I use windows 10 on a desktop computer and laptop. Latest version of Firefox (and Chrome) on both. I have a PS5 Dualsense controller, connected to the computer via an offbrand USB-C cable.

When opening up this site: https://hardwaretester.com/gamepad and connecting the controller, I see a different view on Firefox and Chrome. When using it on Firefox, the controller monitor is invisible and only a couple parameters are shown. In addition, the parameters that update are assigned to the wrong things (such as hitting the home button registering as hitting "up" on the d-pad).

Meanwhile on Chrome, I can open up the site and the controller monitor fully loads, as well as the inputs being lined up properly.

You can see this visually in the attached screenshots. This phenomenon also shows up on other controller testers.

I'm using a web-based game engine that supports exporting, and the same symptoms show up when testing the game out on both browsers, and the issue is also present when the game is exported. I've been working with the engine developer trying to tackle this bug so any help would be greatly appreciated!

I'd like to install the latest version of Firefox without overwriting or disabling my existing installed version.

Is this possible? If so, how?

Thanks

How do I disable the signature verification for addons I downloaded myself and have used quite successfully for years with no problems until this new idiot rollout of settings I for some reason cannot disable? Do I just roll back to the last version or do I have to make changes in the config or is there a way to just delete entire requirement?

Hello, I have many PCs in my home. Office, Kitchen, Lounge, Bedroom, Man-Cave etc etc etc. I do most of my work on my main PC, but I move around a bit. So I would like to be able to copy My entire Firefox Nightly Build across all my PCs. I have about 16 profiles set up for various jobs. I have seen a few posts that tell me to copy the User/appdata/roaming/firefox folder from one pc to another, but after trying this I ended up with nothing. Is there a simple folder selection I can sync across my network? Thanks Col
