I felt like this should be posted since this is such a huge update to Firefox's browser. Posting this in Hot Deals because something this good should probably cost money. Thanks Mozilla for not charging us for thousands of hours of coding.
They completely re-wrote the code to Firefox to make it memory efficient. You can enable hardware acceleration within the settings option to run multiple instances of firefox (like Chrome does) which causes it to perform so much better.
Since many of us view Slickdeals from a desktop web browser I highly suggest you manually update your Firefox browser. It is so much better. Firefox was driving me crazy from all of the slowdowns and crashes. So far this is comparable to the Chrome browser.
Just wanted to give everyone a heads-up. My firefox browser didn't automatically update. I had to push the update through to get it.
