updated Mac with Firefox version 4.0 and now I can't get into my work web site. It allows me to login to the web page but then instead of sending me to the page where I select my application I get an error message.

I have never had a problem like this with previous versions of Firefox - just 4.0.

Error message:

          The page isn't redirecting properly. Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies.

To see whether this problem is caused by the new HTML5 parser feature in Firefox 4, you can turn it off like this:

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the filter box, type or paste html5 and pause while the list is filtered

(3) Double-click html5.parser.enable to toggle it to false (it will turn bold).

Then return to your work site and reload the page.

Does that make any difference? If so, you can leave it that way. If not, you might as well switch it back (double-click that preference again to toggle it back to true.)

If not, and you need to roll back, here's the process:

First, I recommend backing up your Firefox settings in case something goes wrong. See Backing up your information. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)

Next, download and save Firefox 3.6 to your desktop for future installation. http://www.mozilla.com/firefox/all-older

Close Firefox 4.

You could install Firefox 3.6 over it (many have reported success) or you could uninstall Firefox first. If you uninstall, do not remove your personal data and settings, just the program.

Unless you have installed an incompatible add-on, Firefox 3.6 should pick up where you left off. If there are serious issues, please post back with details.

Note: I haven't actually tried this myself!
