I've been running Firefox with no problems on my Windows 7 64 Bit Enterprise system.
Then, an update is installed and it no longer loads (something about versions incompatible). I suspected an add-on had caused this so I uninstalled Firefox, deleted all folders relating to Firefox and reinstalled Firefox 3.5.10 from scratch. No I get an error saying:
'The procedure entry point js_NextActiveContext could not be located in the dynamic link library js3259.dll'
Any ideas on how to get this working again?
