FF4 is pretty bad. Numerous issues since upgrading. Actually had to use IE to get to help site. Why did you do this to us?

Question Very unhappy with FF4. Since upgrading, having trouble loading pages with error message: XML Parsing Error: undefined entity Location: jar:file:///C:/Users/AppData/Roaming/Mozilla/Firefox/Profiles/1wiseqnz.default/extensions/[email protected]/chrome/speedtest.jar!/content/netError.xhtml Line Number 392, Column 33: Have used firefox for a long time and may switch browsers if can't correct this promptly. Having read other posts, sounds like it should still be in beta!

That appears to be a problem with an Extension that you have installed; something to do with "speedtest".

Try disabling or removing that extension in Add-ons > Extensions, then restart Firefox.
If Firefox will not start because of the error, try starting in Firefox Safe Mode and disable or un-install the extension while in Safe Mode, the re-start Firefox using the desktop icon:
