[SOLVED] Flash hangs Firefox 3.6 or 3.7(on XP and linux)

Ok, I've figured out what's going on.

Basically, it's what I suspected all along. Firefox developers have started to add the code for process isolation for Plugins to Firefox 3.6. but it's not working properly yet. Whenever this process loads,however, the browser freezes.

First go to Tools , Add-ons , then Plugins and disable flash plugins ( including Shockwave for Director).

Then go type about:config in Firefox url bar, go past the warnings. Do Filter search "ipc" not quotes . You should see something like this:

For XP:
dom.ipc.plugins.enabled;false
dom.ipc.plugins.enabled.npswf32.dll;true
dom.ipc.plugins.enabled.nptest.dll;true
dom.ipc.plugins.timeoutSecs;10

For Linux:
dom.ipc.plugins.enabled;false
dom.ipc.plugins.enabled.libflashplayer.so;true
dom.ipc.plugins.enabled.libnptest.so;true
dom.ipc.plugins.timeoutSecs;10

To turn off the flash process isolation, change the second line: for XP (npswf32.dll) or for Linux (libflashplayer.so) to false and restart the browser. Then re-enable flash and the browser should be able to load flash pages and play flash video as usual.

For Firefox 3.7 (Minefield) users add second line: According to which OS you have.In about:config ,right click ,create new boolean, paste or type(second line above) and set to false restart the browser. Then re-enable flash and the browser should be able to load flash pages and play flash video as usual.
