How did you actually installed that BF Heroes updater plugin? For Wine IE7/IE8 install (winetricks ie8 flash), the ActiveX control part failed, it never installed. For Wine FF3/FF4 install (winetricks firefox3 flash), the plugin (xpi) was downloaded and browser restarted (which ought to install/load the new plugin) but it ended up downloading plugin again.
For instructions on how I did it, see the test result I just submitted to AppDB (is pending review right now).
Is there any way to install that game without any browser plugin mess?
Yes, see above. But you'll still need the plugin to start the game. Btw, Flash is unnecessary.
