hi billynoah, according to your submitted system data there should be 3 inactive extensions present - not sure why they are not showing up. i this case i'd just refresh firefox which should most likely address the issue...

It turns out the extensions in question are not in the tab that Firefox took me initially. They are in the "unsupported" tab as shown in the attached screenshot.

But why are these showing up as unsigned/unsupported? I went to the add-ons page for Chrome Logger @ https://addons.mozilla.org/en-US/firefox/addon/chromelogger/ and tried to re-install and got this error:

"Download failed. Please check your connection."

This extension was working fine a few days ago but somehow broke on this latest update. But unless something changed with Mozilla's signing mechanism I'm sure it was as signed add-on, as is Adobe Reader.

Any suggestions on how to fix this? Why is addons.mozilla.org throwing that error when I try to re-install?

Never mind, apparently it's a bug. More info here:
