I can't tweet directly, either. I can tweet via some 3rd parties, though. eg www.tweetburner.com and www.tweetmeme.com.

Yeah I used Plurk for a bit to try to post to both. I am on IE with Twitter now with some improvement

There apparently is a Twitter fail due to the new firefox update according to the help site.

The new Firefox doesn't work on my OS, which I suppose is now a mixed blessing!

Yeah... they need to stop adding new versions of FF and just fix the one they have.

Suddenly I'm able to tweet using Firefox again! Yay!

Oo I'll have to give it a try
