For some reason Firefox runs extremely slow when loading my website BKIndustries.net it works fine on my other two sites wholesaleselfdefense.net and wholesalemartialarts.net and Its next to impossible to get into admin control (sometimes has to load for 15 minutes to get in)
However in Internet explorer it will load the site just fine 99% of the time and get into admin controls just fine.
I have exactly the same problem in IE8 and FireFox 3.6. No idea what causes it, but sometimes it lasts for a few days. Chrome is the only browser I've found so far that never seems to have this problem. Cleaning the cache works, but not every time.
I tried to go to your sites, it works fine with IE8 and FF3.6.2 Perhaps you are behind a proxy. Firefox sometimes has issues with proxy under windows server domain.
Well doing that seems to make sure the page loads, but not only does it still go slow (although no longer in minutes) with it set to true but it makes nearly all other websites go slow as well.
