So I noticed the version of Firefox i've been using with Flash Builder 4.5 is increasingly crashing my plugin when in debug mode which is hugely annoying and needless to say makes stepping thru a debug session a not so fun experience.
In case anyone else is interested what i did to fix this is simple:
(Use this at your own discretion im harmless if this blows your computer up :P)
- In your url bar type in "about:config" without the quotes.
- Locate the search field at the top of the document and enter: "dom.ipc.plugins.timeoutSecs" without the quotes.
- Double click on that item and set its value to what ever you'd like to increase the amount of time before it considers a plugin hung. 4 NOTE: if you change that value to -1 it should never time out.
