As discussed on dev-platform, the rough plan is to add CSS filter support to Moz2D. We will provide a (SIMD-accelerated) CPU path, and backends can overwrite that with backend-specific fast paths. The layers system will get a separate GL-based path for the same effects. This is a meta bug to track the work.
I assume you mean the CSS filters as defined in the W3C Filter Effects draft like "filter: blur(5px);", right? Sebastian  https://dvcs.w3.org/hg/FXTF/raw-file/tip/filters/index.html#FilterProperty
Both those and SVG filters, really.
Why does that always happen :( ^
Is there any timeline/forecast for adding these css filters? Chrome/Safari/Webkit supports them since ages ago and they are much needed by so many developers around the world
Several people are actively working on this. Did you wish to join in and help them?
i wish i had the technical skills to help as i would for sure do it, i appreciate very much the generosity of everybody working on this, i will for sure be looking to help in testing this when it comes out, best wishes
Now that bug 1057180 is fixed, marking the META bug fixed.
