OK, the issue must be related to the browser. Once again, I've hit a period where I can't make long posts in
Firefox, but I just tested it in Explorer and it has no problems.

Blast... I hate Explorer... oh well.
All very peculiar. It would appear not merely to be Firefox, but you+Firefox?
I don't mean that in any nasty way - just that no one else seems to be getting the problem you describe.
I mainly use SeaMonkey, but I do occasionally use Firefox (3.0.3) with a selection of extensions (AdBlock Plus + Element hiding, BBCodeXtra, Greasemonkey, Image Zoom, Live HTTP Headers, NoScript, Ubuntu, Web Developer) and plugins. I've noticed no problems.
I know there were some complaints about Firefox 3 being flaky, at odd points, but I don't see where that matches up with what you describe.
I wonder... if there are extensions that you can't live without, you could have a shot at using Seamonkey (
http://www.seamonkey-project.org/ ), just to verify if you are get the same problems (after all, the underlying engine will be the same).
===================
And finally, just to be sure, I've posted this using my Firefox.
