Firefox shutting down by itself when opening up a PDF file with Adobe Acrobat DC

Lately I've been seeing Firefox apparently shut down all on it's own. Most times it would happen right after opening up a PDF attachment in our Yahoo webmail email with Adobe DC. I thought that by clearing the cache and history this would fix it. It did not. The only thing that seemed to work was to open up the PDF using a browser instead of Adobe. I thought that it might be an isolated case since it was only happening on the office computer. I was using a different computer this morning and it happened on this computer as well.

I ran Firefox in 'troubleshoot mode' and it didn't make any difference. The only thing that seemed to make a difference was to open up the PDFs in a browser instead of Adobe Acrobat DC?

Hi Greg, some other users have reported that their Yahoo mailbox or open message tab closes when they open an attachment. I'm not sure what is causing that and haven't gone into Yahoo recently.

Does it help to open an additional tab (Ctrl+T) beforehand so when your main tab closes, you can use of these methods to restore the closed tab without having to restart Firefox:

  • Right-click an existing tab > Reopen closed tab
  • Ctrl+Shift+T
  • menu button > History > Recently closed tabs

Hi Greg, I've tested this out a bit more and posted comments in a newer thread:

(Your thread will expire in a few weeks, so you might want to continue in the new one in case this isn't solved soon.)
