Cannot open pdf file with Firefox 11.0

Firefox automatically upgrades the version I am using. Since it was recently upgraded I cannot open pdf files. Am faced with a blank page. I went through some of the suggestions on these pages and when I opened the Tools window, there is a warning:

Firefox PDF Plugin for Mac OS X is incompatible with Firefox 11!

Is there a way around it? Or is it time to say goodbye to Firefox and move to Safari?

I had the same problem. Go to Tools>Add-Ons>Plug-Ins, and disable Adobe Acrobat plug in. Once I did that, my PDFs opened in Preview again.

When Firefox updates, it turns off add-ons that are not compatible with the new version. In addition, add-ons that may have been automatically installed by other programs without your knowledge (third party add- ons) have been disabled. For more info about re-enabling add-ons, see the link below. http://support.mozilla.org/en-US/kb/Add-ons%20are%20disabled%20after%20updating%20Firefox#os=android&browser=m10

Yes, as posted above.

There have been problems reported with the latest Adobe Reader update on Mac.

See [/questions/925119] You can disable the Adobe Reader plugin in Firefox and use the Adobe Reader program or Preview instead.

Thank you so much! (Until the next upgrade. I think that Adobe is sending me "reminders to upgrade..)
