Can't Install on Firefox 8.0 Rated 1 out of 5 stars

It says that it's compatible with firefox 8.0 but when I try to install it it says it's not compatible with Firefox 8.0 what the heck?

This review is for a previous version of the add-on (0.9.87). 

That is not a ChatZilla problem, it's a Firefox/addons.mozilla.org problem! In this case, addons.mozilla.org has been having uptime issues the past two days and this can prevent Firefox getting the compatibility information correctly.
