Where did you get Firefox from? What security software are you running?

Searched for mozilla firefox on google and clicked the first link

Just as a test, download 105.0.3, Beta, Dev, or Nightly from Mozilla and see what happens. Make sure to manually install in a different directory.

As a guy with almost zero IT knowledge, can you please clarify what you meant for different directory?

Please don't give up on me. I installed nightly. i think it's, as you asked, in a different directory. What do i do now?

Cool. Are you getting the same message about Enterprise? For a person with no IT skills, you provide a lot good information from the start! We need more users like you,  ;-))

I didn't get the message about enterprise with nightly.

Great. If you don't want to use the bleeding edge browser (Nightly), you can download the current version 105.0.3 from that same link. Do you have data in that enterprise controlled browser?

I uninstalled and reinstalled firefox and i am not getting the enterprise message anymore. Thanks for the help.

Using Firefox from Mozilla right?

Mark it as resolved if you have no further questions. Also, I suggest you run more than one version of Firefox as a backup if you have bookmarks and logins saved. see old screenshot

Thanks for the help. And yes i'm using mozilla firefox
