Firefox browser closes when launching pdf
Whenever I click on a pdf file (either from browsing my file system or clicking on pdf link in the browser, Firefox crashes - all open instances of Firefox close.
As a workaround, I have to right-click on the file (if file explorer) and choose open with Adobe Acrobat. If there's a link to a pdf on the Internet, I have to right-click and choose Save link as - and then save the file locally.
Why can't firefox open a pdf file?
