We really should have the extension developers look at this and see if there's anything they can do on their end.
Chatting with Tomcat on IRC he mentioned that you, sicking, suggested we run the extension with various parts disabled to find what the leaky area is (a la binary search). We do not have a debug build of Firefox and we're unable to produce the leak report Tomcat showed when he opened the bug. Even though we develop the extension, I don't know if we're the right people to address the problem as we're lacking the tools, and possibly knowledge, to do so. Let us know how we can help. You're most welcome to download and give the extension a try from www.webvisum.com - tomcat mentioned that he simply installed it and went to his googlemail account to produce the report above. Thanks
Not blocking, but wanted if it's something on our end.
