In order to uninstall a possibly unwanted extension, please do the following:

1. From the Firefox window click the Firefox button at the top left and select Add-ons, or, if the Firefox button is not shown, click the Tools menu and click Add-ons.
2. Once the Add-on Manager has opened in a new tab, click the Extensions button on the left side of the window.
3. You should now see a list of your installed extensions on the right side together with buttons on the right side of each extension.
4. To remove an extension from Firefox, simply click the Remove button. You should see a message that informs you about the successful removal of the add-on.
5. Note that some add-ons require a Firefox restart to be removed completely. To perform a Firefox restart after the add-on removal, click the Restart now link in the message.

You can find further information about uninstalling extensions in the following articles:

Your system details list shows two Flash plugins, one a very old Flash 9.0 version that you should remove

• Shockwave Flash 11.5 r502
• Shockwave Flash 9.0 r45

You can set the plugin.expose_full_path pref to true on the about:config page to see the full path of plugins on the about:plugins page.

• http://kb.mozillazine.org/Issues_related_to_plugins#Identifying_installed_plugins

It is best not to leave that pref set to true as it exposes that full path to web servers via the navigator.plugins object, so reset that pref to false after you are done with the about:plugins page.

Want to hold off on this post, but don't know how to back out of this response. I want to try Cor-el's suggestions.

I'll let your know what happens.

So I got rid of web2pdf by closing out the add-on. That uninstalled the add-on, but I still can't print out any pdfs. I removed Shockwave Flash 11.5 r502, couldn't find Shockwave Flash 9.0 r45, and didn't understand the Mozilla page on plug-ins.

"Adobe PDF Properties" tells me my PDF printer is working properly, but when I attempt to print a PDF, I get a pop-up window that informs me of an "error printing PDF." If I try again, the popup window tells me that my "Adobe PDF" is in "error status" until I remove the queued document.

I never had this problem before I downloaded print 2pdf, and now that I've uninstalled it, the problem remains.

How do I regain my Adobe PDF function? Any steps I can take to set my system back to its original operational state? Would reloading my Adobe CS3 solve the problem? Is there anything I should/can do before I resort to that (a very timely process)?
