64-Bit Firefox, Why Use It?

Out of curiosity, how does a 64 bit web browser benefit the user? I remember seeing a 64 bit version of internet explorer 10 & 11 a few years ago, but I always used 32 bit since I had issues with 64 bit not working.

Better performance, and support for more memory usage by web apps. Mostly not a big deal, which is one reason why 64-bit browsers haven't taken the world by storm just yet. Another hindrance is backwards compatibility with plugins.

lol. I did hear roomors that Microsoft was going to make a 128bit OS soon, I guess it's so awsome that nobody is ready for that level of awsomeness yet. 😛

Thanks for your answer Sakkura, I didn't know that 32 bit on software was still memory limited. I thought that was an OS only issue.
