As Pablo has mentioned, some extensions do not work in 64 bits version ‎of WB. There are some extensions already exist to be uploaded to 64 bits ‎version, but some don't work in that version.‎
I would like to know if there is a way to convert 32-bit-extensions to 64 ‎bits. ‎
‎ Many thanks in advance.‎

All official WB extension(s) have already been ported over from 32-bit to 64-bit. All other extensions should (user made) should work in both.
