I had filed this question earlier in stack overflow but couldn't get an answer.

Please check the link out as it contains pictures to show you what really is going on. To summarize, I am using svg blur filter in an image like the following:

<svg id="blurjs-10">

  <filter id="blur10px">
     <feGaussianBlur stdDeviation="10" in="SourceGraphic">


In "firefox on windows" the blur quality with the above code is really really bad. To improve this I used filterRes tag. It works better but not completely solved. Chrome, safari and even IE10 display blur nicely.

If you want more examples:

If the photo opens in a modal, the background is blurred. If not try clicking the "open picture in modal" button at the bottom menu bar.

The blurred background looks really ugly in windows firefox. However in chrome, safari the background blur is really elegant.
