I'm wondering if, because of the emphasis on Javascript in the later versions of vB, along with the added mods that also include Javascript files, if the loading issues is simply with javascript execution. If this is the case, I may start slowly removing some features/javascript code that are not essential.
Give 10.53 a try I'm using the latest FF 3.6.3 and haven't experienced a loading problem like yours.
