Mozilla 15 is Released, And Finally Fixes Memory Leak!
Now, this IS great news! Mozilla has fixed their memory issue, finally!
“Mozilla has released Firefox 15 for PCs, smartphones, and tablets. The most standout features are a completely silent background updater (like Chrome), significant memory footprint improvements, a built-in PDF reader, better SPDY protocol support, and a new native UI for Firefox Mobile on Android tablets.
Mozilla debuted an early version of the background updater in Firefox 12, but it still harried the user with various pop-ups. With Firefox 15, the browser now downloads and applies updates in the background, and then switches to the new version the next time you open the browser — just like Google Chrome.
The Firefox add-on memory leak has finally been fixed. For almost as long as I can remember, the only surefire way to reduce Firefox’s bloated memory footprint was to close it down. In theory, closing tabs should have the same effect — forcing add-ons to relinquish their memory allocations — but until now it hasn’t. Your mileage will vary, depending on which add-ons you use, but in general you should notice quite a big reduction.
The built-in PDF reader, provided by PDF.js, is turned off by default but can be turned on by visiting about:config and setting pdfjs.disabled to false. After some preliminary testing, it seems about as capable as Chrome’s built-in PDF reader, but a bit slower.”
