Mozilla & Gecko clones Mozilla Firefox has been listening to recent memory complains, and as a side effect tested the browser's scalability to the extreme with memshrink's improvements. The results are shocking: For 150 tabs open using the test script, Firefox nightly takes 6 min 14 on the test system, uses 2GB and stays responsive. For the same test, Chrome takes 28 min 55 and is unusable during loading. An optimized version of the script has been made for Chrome as an attempt to work-around Chrome's limitations and got an improved loading time of 27 min 58, while using 5GB of memory.

That is all very well and good but it still doesn't address the fact that non-Windows users are treated like second class citizens; high CPU utilisation


Huh? Without more specifics I can't reply to that. But most Firefox developers use non-Windows platforms, I'd say by decreasing order it's Mac, then Linux, then Windows. So when they profile and optimize stuff, more often than not it's on Mac or Linux.

lack of NPAPI pepper extensions (which leads to craptastic Flash performance when compared to the plugin running with Safari)


I actually don't know what these are but the main guy working on NPAPI is full time on Mac... so I don't think it's an afterthought. File a bug maybe?

then there is responsiveness issues


Specifics?

lack of hardware acceleration


On Mac there has been compositing acceleration since Firefox 4. Content acceleration is not yet available on Mac as there is no Direct2D equivalent there. Direct2D means that on Windows, the hard work is already done for us, that's why Windows got content acceleration first.

On Linux, there's been XRender content acceleration for a long time, but it's not always great. Compositing acceleration is still disabled by default as due to texture_from_pixmap weirdness it's harder there than on other platforms, but there's a good chance to finally have it on by default in Firefox 9. Content acceleration by OpenGL is still not available for same reasons as on Mac.

Content acceleration on Mac and Linux is on the radar, follow the Azure project. Whenever it gets either a OpenGL or Skia backend, that will give us that.
