How do You remove an incompatiable extension from your computer that's been disabled by Firefox (Smart Printing Button 1.0) but can't find it on the hard drive?

I was cleaning up my Add-Ons, etc. and noticed that if the extension, Smart Printing Button 1.0 is disabled b/c it isn't compatible with my current version of FF 18.0.1, why not uninstall it and move on? I searched for answers on how to do that, but have been coming up empty. I searched my C Drive for the HP program Web Printing (as suggested by HP forums) and found nada, I'm thinking I might have deleted it (not uninstalled it properly) as I felt I didn't need it and now the extension remains. How do I remove the Smart Printing Button 1.0 extension listed on Firefox's extension list given the current situation???

That extension is likely to have been installed globally and is found via a registry scan.

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:

You may need to remove that extension manually.

The hardest part of doing that might be figuring out which folder that extension is in, if you have a large number of extensions installed.

~~~iamjayakumars~~~ - I have already tried to do that prior to posting my question, I'm sorry for not detailing that I had. There is no option to remove this extension, none (like say my Yahoo browser plus extension), it simply says (with a yellow triangle above the extension's name) SmartPrintingButton is incompatible with Firefox 18.0.1. No where within that shaded box is there a way of clicking remove, or disable, FF has already disabled it for me.

~~~the-edmeister~~~ - I followed the steps from that link prior to posting this question as well, again, I apologize for not saying that I tried that option as well. When I found the folder labelled Extensions, there were only two listed, and either was listed as one being related to the HP Smart Printing Button.

I don't want to try and make the extension compatible, I just want to delete it from my computer &/or as a listed extension that FF recognizes. It appears (the program, Smart Printing) is no where on my hard drive , or any other sub-folders. How might I be able to fix this? Also I went to HP and I reinstalled Smart Print (it's an add-on for I think Bing's toolbar), uninstalled it and still nothing. There seems to be no way of even trying to Remove it from FF extension. I will try to reinstall Bing Toolbar( it has ready been uninstalled), then reinstall the HP Smart Print add-on, then uninstall both and see what happens next.

Thanks guys for the help:-)

Hi Cor-el,
