In addition, when I visit my site at InternetTvDotCom some of my widgets aren't visible such as Twitter and Sharebar widgets, and my rotating tag cloud widget isn't rotating anymore when using my Mozilla browser.
Now when I use my IE and Safari browsers everything works fine and appears normal.
I've disabled, refreshed and updated all plugins, including changed themes using WP default theme, cleaned my computer (ran security software, cleared recent history, cache, etc.). I also uploaded WP 3.1 manually, followed other posts, articles, and instruction to remedy the problem but nothing seems to work.
I have many other WordPress blogs that use different themes and none of them are experiencing any problems in Mozilla.
Any ideas or solution will be greatly appreciated...
