Yes, I can still see the problem, and on all themes I've tried. The content fonts look normal compared to the same pages in Epiphany, though it's possible I changed the Firefox font settings at the time I reported this bug.
I'm attaching a screenshot that shows the difference in interface font between Firefox (left) and Epiphany (right). ** Attachment added: "Screenshot" http://librarian.launchpad.net/5820121/firefox%20bold.png -- Font in firefox is bold since upgrade https://launchpad.net/bugs/70299 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
