easy to use and fits my daily work routine perfectly

On a brand new Windows 11 Home Laptop in Firefox 140.0.2, it will take a screenshot, but will NOT save it as a picture and apparently, or if it does, I can't find it anywhere. I'm having to use the Copy to Clipboard option, which adds HOURS to the project I am working on. Might be able to figure out what is wrong with this "thing" but I do NOT want to spend a year or two trying to get a Masters in coding just to fix something that someone else can't do right in the first place.

JUST SAY NO!!!!! TO BAD EXTENTIONS!!!!!!!
