Login & Content Encoding Error! Not Happy!

As per the subject, I log in using my browser Mozilla Firefox 3.5.2 I receive the above error, seen here: [URL= http://img193.imageshack.us/i/contentencodingerrorfir.jpg/][IMG] http://img193.imageshack.us/img193/8717/contentencodingerrorfir.th.jpg[/IMG][/URL]


It happens everytime with this browser, I can't seem to figure out why. I've been using the laptop for the last week or so with the same version of firefox, same add-ons etc, everything the same all but the error, which I didn't receive whilst away. Now I come back, jump on the desktop machine and get comfortable, log into Zoho and voila: Error! :oO If it's worth mentioning, I've tried to use the zoho 'beta' plugin, but this isn't working, I've also uninstalled and tried the non beta plugin without any success.
