Firefox Community Forum

When trying to launch the browser from a network folder, I encounter the errors shown in the screenshots. If I launch the browser on one computer, everything is ok, but if I need to launch it on at least the second one, I encounter this error until I close the browser on the first one. I don’t know what could have happened, because I didn’t touch the configuration and everything worked fine for us last year. Nothing was updated or changed. Firefox Portable ini file configuration:

When I play games like classic.minecraft.net or krunker.io, the pointer speed is very slow. So I would like to know if there is a way to change the pointer speed of firefox.

Running Linux-Mint on my laptop. Trying to run an epson ET-2400 ink jet Printer. Need Driver for printer. I have seen some information about software that needs to be added to "talk" to the printer but I cannot find it now. Please someone help.

I am trying to hide the AI results on Google search, but I can only find instructions for Chrome. I prefer to use Firefox, but I loathe the AI results. Is there any way I can go back to the way it was before on Firefox?

Thank you for your help.

      Please apply the Firefox online database to all United States of America computer software to allow transfers of data from forthright log in partners such as native Asia citizens that migrate or travel into the United States of America districts. the United Nations Council and the Whitehouse will be contacted by me personally to insure this operation of trust will happen as i expect as Majority shareholder of funding to Mozilla, Dell, Google, Microsoft, Apple, Etc.

Thank you, Dr. Martin Rivera Perez Gonzales II

This issue came up in early April 2025.

Programs other than Firefox (e.g. Edge, Media Player) behave normally: when playing sound, if nothing is plugged into the 3.5 mm jack, the sound comes from the desktop's external speakers; and when an audio device (speakers or headphones) is plugged into the 3.5 mm jack, the sound instead comes from that device.

Where as Firefox will play using the internal speakers as expected, but when a device is plugged into the 3.5 mm jack, no sound signal goes to that device.

It seems then that the hardware is okay, and the problem must lie within Firefox, or within a Windows setting that is very specific to Firefox.

The sudden onset earlier this month may point to either a Firefox update, or (less likely) a Windows update.

I paid for the adblock premium and now youtube is not even skipping the ads, they just play and firefox doesnt seem to be blocking anything. it was actually better before i paid anything, this feels very scammy. wth is happening?
