The new Firefox closes .swfs during while working in the debugger in swf's. It would be cool to have integrated a feature that switches the config value of firefox to a reasonably long time while debugging and sets it back after the debugging process stopped: Example: 1) I have dom.ipc.plugins.timeoutSecs in about:config of firefox set to 10 2) I start my debugging process in FDT 3) FDT sets the variable of about:config to -1 4) I stop debugging my .swf 5) FDT returns to the original value I had before last time's fdt debugging.
