for anyone who is interested, "status-4-evar" has been updated, so that it now is compatible with FF 25:
»
addons.mozilla.org/en-US ··· -4-evar/before it had been updated, i had installed the latest beta version, since the regular version wasn't compatible with FF 25.. i uninstalled the beta vesion and installed the new regular version, but it didn't work! so i uninstalled the new version and reinstalled the beta version, but it didn't work! so i uninstalled it and tried "resetting" all of the settings for "status-4-evar", in FF's "about:config", and then reinstalling it, and then it worked! so i uninstalled the beta version, reset the settings for "status-4-ever", in FF's "about:config", then reinstalled the new version, and it worked!
the trick was to go into FF's "about:config" and "reset" all of the settings, there, for "status-4-evar", after having uninstalled the beta version.. maybe others, who haven't installed the beta version, won't have to go through the same thing..
