This is Adobe Reader plugin's problem. I believe it's caused by the "Allow
speculative background downloading" or the "Allow fast view" preference in Adobe
Reader and it doesn't properly stop when you Back out of a PDF file before it's
finished, causing Firefox to hang.

I don't think its an issue with Adobe. I am using Firefox 0.92 and this problem
occurs on each and every instance a PDF is loaded in the firefox browser. Not
only you can't back out, you can't even close the browser window. You have to
kill the process.
