UPDATE: I have found through a long process of trial and error that it was the Google Personalised Homepage (google.com/ig) screwing up the Firefox search box focus. Presumably it's still a bug in Firefox, as it shouldn't happen, but it's something to do with how Google uses Javascript to steal focus for its in-page search box. I created a version of the Google homepage saved locally to disk in which I removed the steal-focus Javascript code. Unfortunately of course, that means I can only have a static Google search page as my homepage which means I lose the benefits of the nice Google personalised homepage. But it's a lesser price to pay in order to have the Firefox keyboard shortcuts working as they should.
Anyone else having a problem with Firefox 3 for Mac having multiple fields at once 'focused', making it impossible to copy/clear/type new data into the contents of the field?
I make extensive use of the CMD+F (find within page), CMD+L (location bar) and CMD+K (web search) shortcuts in Firefox. But since the release of Firefox 3.0 for Mac, Firefox frequently gets confused about which field should be 'focused' (the field that is active at the time.)
