I totally changed my building from VC6 to VC7 and get some optimization of my version. And the rich text editing bug (Gmail) is also removed.
I did a speed test just now. This build is much faster than my PR10 and is very close to W-B build which is with Gecko 1.8a2. However, I havn't figuered out why some people have difficulty in running this one right now. But I think I would stick with VC7 now since it has a big speed improvements when building.
However, I still kept the previous chrome, that means the previous RSS bug still there, I will try to solve that one later.
