I recently moved over from Windows, and I apologize if this is a stupid question but I read the manual, tried searching various terms, and could not find anything that helped me.
I don't know how to switch focus in Ubuntu. For example when I click something to download from Firefox, and the pop up comes up asking if I want to save the file, I can't get my mouse to be active on the new window. I try clicking the top of the new window, I tried clicking on the top of the active window then the top of the new window, I pop up the dash and then put it away.
I've tried Ctrl+Alt+F2 then Ctrl+Alt+F7 because someone with a similar problem solved it by doing that each time but it doesn't work. I just Alt+F4 the browser then push tab until the save button is highlighted then push enter, but its not a solution that is practical.
I tried reading the manual, Ubuntu desktop tutorial, YouTube videos for complete beginners, and the YouTube video user's mouse works fine while mine does not, even if I mimic his exact actions.
I reinstalled Ubuntu and followed everything the guy did for searching files and my mouse does not work like his does. I'm sure the solution is really simple but I've spent 2 hours a day for the past 2 days Googling on a separate computer and I can't find a solution and its stressing me out. Please help.
