IonMonkey, Retina Support Make for a Faster, Sharper Firefox
If you’d like to switch to Firefox’s beta channel, just head over to the beta downloads page.
There are quite a few new features for web developers in this release, including support for the CSS 3 @supports rule I wrote about yesterday. Firefox 18 also supports the latest CSS 3 Flexible Box Model syntax, though it’s disabled, ahem, out of the box. To test out your Flexbox layout in Firefox 18, open up
about:config and search for “flexbox.”
Developers working on nice shiny new Mac laptops will be happy to hear that Firefox beta now supports Retina Displays.
The security-conscious have cause to celebrate as well: Firefox 18 has, at long last, landed a setting to disable insecure content on secure websites. It’s off by default since it would probably break a lot of websites (mixing HTTP and HTTPS content on the same page is, sadly, quite common), but if you’d like to give it a try, head to
about:config and search for “mixed” which will bring up the relevant options.
For more details on everything that’s new in Firefox beta, be sure to read through Mozilla’s release notes. If you’d rather not use beta-quality software for your everyday browsing, you’ll need to wait until second week of January when Firefox 18 is scheduled to arrive.
