A problem with Firefox 3 and WordPress 2.5.1: When typing into the main body of a post in the visual (rich) editor, hitting the apostrophe will bring up the Firefox Quick Find box above the status bar. With this problem, it is not possible to type the apostrophe character into the post text box. This bug does not occur in other types of text boxes or in the non-rich editor.
I have tried every fix listed in the Firefox Knowledge Base and online. Nothing works. In the past this has been a known issue in Firefox except that it occurred in all types of text boxes rather than just one kind. Not only that, but a handful of solutions existed. I tried them all and had no success at fixing the problem.
In short, this renders useless the editing box for posts in WordPress.
Any ideas for fixes?
