I finally got around to picking up a Pi2 a week ago. I installed Ice Weasel so I could have access to a couple of Firefox plugins I don't like to live without. IW has worked fine for this entire time, but today it has dramatically slowed down to the point where it is unusable. The stock browser still works fine, so that is not it. I also have my eye on the CPU Usage Monitor and it doesn't get above 30% while trying to do things in IW.
Has anyone else experienced Ice Weasel on a Pi2 running just fine for a week and then screeching to a complete halt?
