Firefox 3.5 Screws Up Color Management

Earlier I noted how Firefox 3 has support for color management and can show your photos like you meant them to be seen on a profiled monitor. I was also excited that Firefox 3.5 would turn on this color management by default. I just upgraded to Firefox 3.5 this morning, and color management is indeed on, but Firefox has screwed up color rendition. Colors now look horrible because of a bug that wasn't fixed in the final release, and unlike in Firefox 3, there is no setting available to make things look right. The best you can do is set gfx.color_management.mode to 0 in about:config to turn off color management altogether.

On top of that, Google Gears doesn't work anymore on Firefox 3.5. A terrible start for a new version. Now, how can I downgrade...?
