About:config in Firefox changes list?
I changed one too many settings in about:config in the latest version of firefox, and now I am getting lag on opening multiple tabs. The lag is short but noticeable, and I don't like it.
My questions are
1) Is there any way to undo specific boolean/integer changes, is there a record kept of what's changed in the last 3 months Of course, I like some of the changes, but not all of them. Once I see a list of changes made, I will remember which specific changes messed up my browsing.
2) How do I go back to default settings in about:config?
thanks
