Ad Block Plus won't install. All steps are normal, and firefox reboots after installation steps are followed, except there is no ABP stop sign or any other signs that ABP is functional. No error messages appear.
Help! I am so used to ads being blocked that I can't tolerate them!
I preemptively removed extension.cache, extension.ini, and extension.rdt, no help.
Firefox version 3.5.5 (.NET CLR 1.1.4322)
Ad Block 1.1.1
Windows XP Pro Version 5.1.2600 SP3 Language 1033
Norton Internet Security Antivirus Active
I first noticed the problem at my home page http://my.earthlink.net
The only Add-ons are Adblock Plus, Java Quick Starter, and Microsoft .NET Framework Assistant 1.1
