Check your Firefox version (in the “About Firefox” window) and look for “(32-bit)” or “(64-bit)” after the version number:

If you’re running 64-bit Windows ( here’s how to check), your Firefox may already be 64-bit. Linux and macOS users, fret not, you already enjoy a Firefox that’s optimized for 64-bit. Also, with the jump from 32 to 64 bits, a security feature called Address Space Layout Randomization (ASLR) works better to protect you from attackers. Here’s the key thing to know: 64-bit applications can access more memory and are less likely to crash than 32-bit applications. What’s the difference between 32-bit and 64-bit? How much less? In our tests so far, 64-bit Firefox reduced crashes by 39% on machines with 4GB of RAM or more. That means you get a more secure version of Firefox, one that also crashes a whole lot less. you guys really pood the scrooch on this one.Users on 64-bit Windows who download Firefox can get our 64-bit version by default. I won't be using your browser again until you fix this pile of burnt hufflepuff pubes, because right now it's about as enticing as a bathtub full of half-chewed twizzlers. considering that it's only purpose is to access the internet, that's pretty crummy.so get it together. you took away every perk, you made it harder to use, and you eliminated it's ability to access, oh, i don't know, about half of the internet. I don't know what you guys were thinking, but man, i've never seen an app get this much worse in a single update before.

does your page use javascript anywhere, like millions of websites do because it's gourd-dame universal and everybody uses it? nope, java is disabled. wanna open a page via a link in a 3rd party app? forget it, never gonna happen. half of the pages i try to visit won't load. you took away the thing that made is special and made it a really extra rump-humping crappy browser. Huge update, tons of changes, some i think were actually pretty cool, although it's a different browser now, which makes it sort of hard to use right off the bat.but jeez louise, basically no add-ons.NO ADD-ONS? what the bloody fark!? that was like half the point of firefox, bros! that was what got people excited about using it! You took away the thing that made it special and made it into just another browser.well, almost.
