I've seen this on multiple computers of widely different ages of hardware, I haven't checked on a windows PC but on multiple linux (ubuntu and linux mint) systems with up-to-date copies of firefox ESR I've found the whole browser freezes when you open a long (several hundred pages) PDF file. The task bar at the top keeps working, however even if you close the tab where the pdf was all other tabs you have open are just wide below wherever you had managed to scroll to before the crash happened. The reload button is clickable but tabs don't actually reload. Links in pages are not clickable and buttons on pages act as if they aren't even seeing you hover over them. I've found no fix except closing firefox and reopening all your tabs except the one which had the big pdf in it. This has not just happened with one file but with many pdf files found online.

Can anyone suggest a fix, or confirm that they've seen this too?

Thanks

I can't say that I've seen it, but don't you have the option to force PDF files to open not within Firefox itself, but in whatever PDF reader you have set as your default on your system?

 

I've done this in Firefox on some of my systems before.  This is the most recent version of the instructions I can find:  https://support.mozilla.org/en-US/kb/disable-built-pdf-viewer-and-use-another-viewer

 

It's a workaround if you actually like viewing PDFs in the browser.  In my case, I hate dealing with them there and routinely make this particular tweak.

I do like viewing pdfs in the browser, but this has got so bothersome now that I've applied the workaround anyway. I'm viewing them with linux mint's "document viewer" now.
