Unable to install Ad Block Plus

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

Microsoft .NET Framework Assistant 1.1 has been known to cause a lot of problems and sometime certain anti-virus software can cause issues too. First thing to do is remove the Microsoft .NET Framework Assistant 1.1, if that does not help try disabling your anti-virus.

Uninstalled Microsoft .NET addon - no help. Norton Internet Security has been on this computer working well with add block for some time - I doubt that it's the culprit

Please use method 2 listed in http://support.microsoft.com/kb/963707 when uninstalling .Net Framework Assistant - it won't really uninstall otherwise.

Did you disable Norton Antivirus or the add-on that it installed? I would suggest you do the latter.

I tried to follow the steps in the web link for uninstalling the .Net Framework Assistant, but there is no {20a82645-c095-46ed-80e3-08825760534b} subkey. I followed the rest of the steps in the article that remove microsoftdotnet and dotnetassistantextension

I disabled, then deleted the Norton Internet Security add-ons.

The results are still the same. ABP appears to install, but there is no ABP stop sign to the right of the search box, or ABP content.

Curiously, Tools - Add-Ons displays add block plus as an add-on, with no ABP stop sign icon, and clicking Options locks up the computer.

Clicking Options doesn't lock up anything - it displays an invisible (non-existing) modal dialog, you can close it by pressing Alt+F4. It's the same issue as in viewtopic.php?f=1&t=4742 then and I have no idea what is causing it.

I was having the same problem, tried all the fixes I could locate online, but to no avail. I finally reloaded this version from download.com and it cleared up the problem. http://download.cnet.com/Adblock-Plus/3 ... 29692.html

That version is ancient, released almost three years ago...

I've been having continuous problems installing Firefox add-ons since I upgraded to Firefox 3. I don't recall which forum I read this in, but a suggestion was made to uninstall Ask Toolbar. I finally tried this, and voila! Ten extensions that repeatedly had this message in the add-ons menu: "this add-on will install when Firefox restarts", immediately and miraculously, installed . These included Adblock Plus, No Script, McAfee Site Advisor, Yahoo Toolbar, and Real Player Browser Record Plugin, to name a few. I can't believe such a simple thing could solve such an annoying problem.

After a little searching, I must give credit where credit is due. I found this solution on Bright Hub, on the following page: http://www.brighthub.com/computing/smb-security/articles/90065.aspx
