Hop-over to FireFox

"Regular" Mozilla browser starts to annoy me - sometimes I have problems with rendering correctly some websites (like eBay for example: two days ago I tried to change my e-mail contact address and, at some point, eBay required me to type in some number, generated to avoid bots as a GIF and it did not get displayed!). Besides, with all those extensions/plugins available more often for FireFox, it looks that it's "bleeding edge" software (like all my machine is!).
