User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0 (Beta/Release) Build ID: 20130910160258 Steps to reproduce: I will produce a simple test case when available, but here is my scenario: 1. a position:fixed overlay div has simple css transform/transition applied to it, transition is triggered by adding a class or :target. 2. when such div has only background-color or linear-gradient, the transform appear to be smooth. 3. when radial gradient is applied, firefox appear to skip frames a lot during transition. (Firefox on Windows or WebKit/Blink browser on Android does not experience such issue. My device is Samsung Galaxy Note 2, tested using both Firefox 25 stable and Firefox 26 beta) Actual results: transition appear to be laggy Expected results: transtion should be smooth.
Are you able to reproduce with Nightly (http://nightly.mozilla.org)? And yes, a test-case is much appreciated.

I am seeing some odd behavior on Firefox 28, checked it on an android G2 phone. The radial version is jittery and moves the text oddly across the screen.
