I'm on the beta channel and was running v43 up until last friday, when I decided to upgrade to v45. After that I can no longer copy/paste from Firefox to any other application, including Firefox itself. Apparently I can't seem to drag and drop content into Firefox as well. I googled around and found many people were having issues as of v44, but their problem usually consisted of being unable to copy/paste from Firefox to some other applications, and they were told v45 would fix it (maybe it has for those external programs, but the issue remains for me).

Is anyone having the same issue?
