After Firefox has been running for a few days my Debian 12.5 gets really slow. The mouse jerks when it works at all. It takes a minute or two for wndows to close or top. At the moment, Firefox has 19 processes running. Memory is half full, and swap is about 10% used. When I kill Firefox and restart, things go back to normal for a few hours.
What alternatives that aren't such pigs do you recommend?
