Hey there Chop
Not Cleo here either, but much like yourself...I went to Mozilla a few days ago. Very cool so far...and haven't noticed the issues you describe. It does sometimes kinda squish text on pages together...dont' know what's up with that...but it' s no deal breaker either.
Sure do like the extra security of not being quite so vulnerable to all the nasties on the net.
So far...

from this porn slinger!
And the Mozilla mail client is great! So far, I actually like it better than the browser...good stuff all around =)
Hope you get your issues fixed up soon...
