Crashes when deleting browser history Firefox Deletes 300 links each time It then removes 300 links in 20 seconds It takes a maximum of 600 links in two 30-second episodes, for a total of 1 minute to remove It takes 3 minutes to reach 900 links It takes 30 minutes to reach 2000 links The more links I select to delete, the longer it takes I think 60,000 links take a week to remove And when the CPU is removed it becomes 100% and the browser responds with an error message: "not responding"
