Why is Firefox 9 incompatible with Adobe Acrobat?
When the Acrobat 10 plugin is enabled, Firefox menus don't work properly -- they disappear when dropping down, they oscillate, or just the outline is visible without the menu items. Disabling the Acrobat plugin immediately fixes the errors.
This happened once before when an older version of FF was first released.
