When I click on any link in a Thunderbird email message I get the error message:

Firefox.exe – Entry Point Not found The procedure entry point ?DllBlocklist_Initialize@@YAXXZ could not be located in the dynamic link library T:\PQligP sFuvy (X86)\pJPpSox HneiCFv\GwCMqTQ.Oqt.

I tried uninstalling Firefox 27 completely and reinstalling it, and the error is still there. When I uninstall V27 and install the older V26 the error disappears. Id there an issue with V27 trying to work with links from Thunderbird?

I am on a laptop running Windows 8.1 with all current downloads.

Thanks for the reply - as best as I can tell it seems to be some kind of incompatibility between Thunderbird V24.3.0 and Firefox V27. If I install Firefox V26 then everything works as it should. I haven't tried installing a previous version of Thunderbird to see if that makes a difference.

Following up on this issue: I downloaded and installed V28 yesterday and everything seems to be working as it's supposed to work. I don't know what changed, but thunderbird links didn't work with V27 or V27.1 but work fine with V28 so I'm happy!
