Duplicate entries in Add-Ons list? (Firefox 17 on Windows 8)

I'm not sure why, but I seem to have duplicate entries in the Firefox Add-Ons list.

They are:

Software: FF Version 17.0.1 on Windows 8 (Windows Updates are current).

Hardware: Dell XPS 8500 Desktop, Intel® Core™ i7-3770 3.4 GHz with 1 GB NVIDIA GeForce GT 620 Graphics

Try to delete the pluginreg.dat file in the Firefox Profile Folder and maybe addons.sqlite as well to reset the plugin registry databases.

You can also try to delete the addons.sqlite file.

You can use this button to go to the Firefox profile folder:

Thank you. I tried that and still have the same duplicate entries. Also, I have Flashblock and Noscript installed, but neither of them show up in the list. Can you suggest any other possible solution? Thanks.

Here's what I'm seeing.

You can see from the description that the plugin have different purposes, so although they have the same version number, they are different.

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.

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.

You can also see that path in the pluginreg.dat file.

I was having another issue where I could not see anything in the list of Extensions, although I knew there were many. I unlinked this device from sync and did a reset, then re-synced. Things seem to be working now.
