For example, using Firefox for comparison, I have 3 windows open, 7 tabs in total and: [wmcdonald@fedora ~ ]$ ps -ef | grep [f]irefox | wc -l 22 You could go try and figure out what each of those threads is doing with strace or core dumps, maybe go read through some of the upstream project lists and/or issues? Other than 'why are there loads of these' is there a problem? pstree might give you more of an inkling as to how they're being created/consumed.
