Mozilla/5.0 (Android; Linux armv71; rv2.2a1pre) Gecko/20110405 Firefox/4.2a1pre Fennec/4.1a1pre Device: Droid 2 OS: Android 2.2 1. install yesterday's nightly and install the Firefox for android from the market 2. launch only the nightly (verify that only fennec nightly is launched) 3. update the nightly and restart when asked via the notification 4. check the processes to see which version(s) are active Expected: Only the nightly Actual: both the nightly and the Firefox for android from the market are started. Note: 1. I was wondering why I was checkerboarding so much, part of the reason it turns out is because Firefox release was started as well. 2. I'm not sure how many people would be running both on the same device.

How are you checking in step 4?

through the use of ddms. I'm closing this out as a dup of bug 540007
