Cristian, what are the STR?
This looks a lot to me like we're tearing down the plugin instance from within the timer (it could also be calling a timer on a dead instance, but I'd expect that to normally crash earlier in the method) . The comment "Make sure we still have an instance and the timer is still alive" is scary. We should almost certainly be protecting against plugin teardown using a PluginDestructionGuard at the top of PluginTimerCallback. Do we have a good way of verifying hunches like that?
(In reply to Scoobidiver from comment #4) > Cristian, what are the STR? I was able to reproduce this crash always with the following STR, but I cannot anymore now on latest Nightly, Aurora or Beta builds. STR: 1. Open Fennec 2. Go to http://www.adobe.com/software/flash/about/ 3. Tap to activate flash plugin 4. Wait Expected result: No crash should occur. Actual result: This crash will occur. On the latest builds, instead of this crash, I will get some libflashplayer.so crashes. -- Device: Galaxy Nexus OS: Android 4.0.4
It's now #3 top crasher in 15.0b6.
I am always able to reproduce this crash on the latest Nightly by following these STR: 1. Go to http://goo.gl/j3xAP (http://www.digisport.ro/Sport/FOTBAL/Competitii/Liga+1/fc+vaslui+steaua+live+text+video) 2. Tap on any video to enable the flash plug in 3. Tap on the Reader Mode icon from URL Bar Expected result: The page should be displayed in Reader Mode correctly.

Snorp - do you have the time to look into this? If not, please hand this off to blassey to reassign.

Please nominate for Aurora/Beta approval this week, once comfortable with the landed change.
No crashes since 9/9 build it looks like, which doesn't include my fix. Still, seems to be good now.

It's not fully fixed because there are one crash in 18.0a1/20120919 and another in 17.0a2/20120920.
