Comment 8 for bug 720446

It does seem to have returned with a bit more significance though would like to note do see a difference between an older updated install and a fresh 04/08 install which behaves better

Also I'm not sure that the increase of RSS when INITIALLY using the various is not unexpected - dash, .places, Alt+F2, searches in these, the dropdowns, ect. and possibly the global menu ( a bump of about 30 -40 %), seems reasonable that it would

After that though there still appears to be a small per use increase that can build over time, though have not logged long enough to see if it 'caps out' or will continue ad infinitum
