I'm running Firefox and I won't ever go back to IE.. Nor have I ever had any of those issues with the lost posts. Good thing about Firefox is the spell checking.. Like if I misspell a word Firefox automatically underlines the misspell with a red line, exactly like MS Word. Then I right click on it and it brings up a list of words that match my spelling... I love the way the history comes up site by site, my bookmarks are super easy, most everything on the toolbars are drag 'n' drop, I have ad blocker ( 0 flash ad's), so many different options that are easily to execute..
You guys need to make Firefox your default browser..
