Whenever I try to print something a whole buncg of the same tab opens up and after a minute, ther are like 400 tabs open and i can't even see what is wrong.
Whenever I print something or try to open a file, thousands of tabs with the same file open up rapidly.

this thread had some insight, ultimately the user uninstalled and reinstalled and it corrected the problem. Cor-el's response might help too:

You get tabs opening endlessly if you select the Firefox program to handle a file When you get an "Open with" dialog.

Sounds that the builtin Firefox PDF Viewer is disabled or otherwise isn't working. You can check the action for Portable Document Format (PDF) in "Options/Preferences application -> General: Applications" and make sure it is "Preview in Firefox".
Does this link open a blank PDF Viewer window?
