That's not what I meant.
It's fine if filter changes don't affect scripts already shown.
(Of course it would be nice if you could change filters to show/hide all scripts compiled/executed since the extension was opened, but capturing all scripts would be problematic. Especially capturing of all internal scripts (chrome:// etc.) has the potential to freeze Firefox.)
Besides this way you can "stop" capturing events from one site (by adding it to the exclusions) and you are still able to keep the captured scripts in the list.
(Pause capturing stops capturing on all sites which can be an advantage, but sometimes you just want to stop capturing on one site. In this case the exclusion list is more useful.)
What I meant was, that changing of the exclusion list can trigger the bug mentioned in viewtopic.php?f=5&t=4103
* "Number of calls" keeps increasing
* "Average execution time" goes crazy
* Both values should not change (i.e. stay at the value displayed when pressing pause)
