After installing Windows 8.1 Addons won't install in TB 24.3.0
I had Windows 7 and had installed ProfiledSwitcher without any problems. I then got a new computer with WIndows 8, which I upgraded to 8.1 recently. I noticed that I didn't have any addons, so I downloaded ProfileSwitcher, went to "Install from File", clicked on it, then clicked on "Install". When I do it hangs. If I look in the Extensions, it says installing, but nothing happens. I tried another addon (Contact Tabs) and the same thing happens. I have tried a number of times, but they both just hang. I have searched for help here and have googled for an answer, but can't find anything. I can live without the ProfileSwitcher, but it worked well in Win 7.

It is possible that there is a problem with the file(s) that store the extensions registry.
Delete the extensions.* files (e.g. extensions.json, extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry.
New files will be created when required.

If you see disabled or not compatible extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left end of the Search Bar to check if there is a compatibility update available.
If this hasn't helped then also delete the addons.json and addons.sqlite files.

try typing the add-ons names into the search box in the add-on manager (It is on the top right) and installing through that route, just to see if it works better. It is also the "preferred" installation method
Thanks for the reply. I did and it says it "could not find any matching add-ons."
I had closed and reopened Thunderbird and the Add-On mgr did not show Profile Switcher. I had closed it again and opened it and Profile Switcher was there. I clicked on the install and again as before it hangs and does not install.

Thanks! I deleted the extensions in the extension folder as well as those mentioned above and it now installed ProfileSwitcher. Thanks again!!!
