I upgraded to the Firefox 4 browser a few days ago. The text formatting in the rich text box formats correctly. When the message is posted there are no paragraph spacing, therefore the message reads as one continuous entry. The spell checker does not work; the following message occurs. An Unexpected Error has occurred. Sorry, your request failed. A notification has been sent to the development team for investigation. Exception ID: 139B9045. Please click the Back button on your browser.
I’ve submitted your issue to our community support.
At present, Firefox 4 is not supported by Lithium. So, the only option for now is to use a different version browser. Firefox 4 should be supported in one of our next updates. There is currently no timeline for the next update, however.
Thanks for the feedback.
