As Firefox is my pdf browser, when I click on a pdf it keeps opening the file, in an infinite loop, opening tab after tab after tab....
I think my one sentence does it. I am using Firefox as my pdf browser. I click on a file in Explorer, then it keeps opening the file continually in Firefox. If I catch it in time, I can close firefox. If not, I cannot even use the Task Manager. I have to hold the off button until my machine turns off. Thank you for any thoughts on this. I believe it is a bug. WR/~ David

Is the builtin Firefox PDF Viewer enabled ?

Hi David,
This usually happens because you chose Firefox as the program to always use for a particular action, such as opening a certain type of file.
See this article for more information: Firefox repeatedly opens empty tabs or windows after you click on a link
Make sure that you haven't disabled the builtin Firefox PDF Viewer and that the action for Portable Document Format (PDF) is set to "Preview in Firefox".
- Options/Preferences -> General -> Applications

Thank you for responses, cor-el and RobertJ! I was able to get firefox to always prompt me. Unfortunately the loop continues to open tabs when I select "open" with Firefox. When I select "Cancel", none of the tabs have opened my PDF.
Also, I have deleted the "handlers.json" file, restarted Firefox and even restarted my computer. This reset did not change how firefox continually loops in this situation.
I have a one week old (i.e. new) machine running in Windows 10 Pro - version 1909.
Again, thank you.

This seems to have done the trick, cor-el. Thank you.
Of course Firefox updated to v 74.0 right when I was checking this, so I may never know if Mozilla repaired this, or if I did. But in either case, I appear to be great now!
