this message comes up everytime I log into firefox so how can I fix it please?
Does that happen in Firefox safe mode? Maybe an extension is causing it?
This problem is here
Where do you see that error?
UniversalXPConnect is no longer supported in current Firefox releases, so if you visit a web page that uses it then this won't work anymore. Extensions don't need this and shouldn't cause this error because they already run code with chrome privileges.
i'm getting the same error too every time i open up firefox on my laptop windows 7 and i keep getting this.
Error: TypeError: netscape.security.PrivilegeManager is undefined
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
Как только обновил браузер стало появляться это окно всегда при запуске мозилы - фаерфокс: приложение: Java Script Error: TypeError: netscape.security.PrivilegeManager is undefined
Что это значит и что делать?
As posted above, the security manager is no longer supported in current Firefox versions, so if a web page or possibly an extension is still using this to perform actions that require chrome privileges then it is no longer possible to get this privilege.
Only extensions will be able to perform such actions.
Go to Tools: Add-ons: Click on disable AVG Security toolbar
I have disabled the AVG toolbar which has stopped the error message but I can't get into my Hotmail page, I get the message :"We can't connect to Hotmail right now, try again later". Also I bookmarked the TV Guide and now can only see the evening programmes for the current day - I can't view earlier times or following days. Please help - a simply as possible as I am a senior and not very computer savvy,
