We're installing 64-bit Windows Operating Systems (XP, Vista, 7, & 8) onto our hard drives for class along with software and my professor is requiring that all of the software we install be 64-bit as well (if possible). Chrome and Firefox still don't have an official [stable] 64-bit version available, so we've been allowed to use unofficial versions since we all agreed (including my professor) that Internet Explorer is crap--64 bit or otherwise.
We came to the consensus that we are all going to use Firefox-based browsers for consistency sake. They all pretty much look the same as Firefox and each other so Most people are using Waterfox or Pale Moon and a few people have Firefox Nightly* for some reason .__.
Personally, I went with Pale Moon because it runs faster (at least for me) and I don't like how Waterfox tries to trick you into installing the AVG Toolbar crap. I actually really like Pale Moon and have started using it at home since I have Windows 7 64-bit on my laptop. It's also portable which is nice I downloaded Waterfox at home too so I could do a more thorough comparison and for me it is only slightly faster than Firefox, but not nearly as fast as Pale Moon.
So, do you use a 64-bit browser or know of any others (Firefox derived or otherwise)?
