Firefox CPU usage 100%
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:18.104.22.168) Gecko/20061204 Firefox/22.214.171.124 Build Identifier: 126.96.36.199 Firefox starts hogging the CPU with nearly 100% usage if connect-disconnect-connect your internet connection Reproducible: Always Steps to Reproduce: 1. You are in some domain with connected to a wireless/LAN 2. Open Firefox and browse some sites in tabs 3. change you internet connection i.e. disconnect and connect to another wireless/LAN domain Actual Results: Firefox starts hogging the CPU with nearly 100% usage with the new connection Expected Results: Firefox should re-connect all the websites using the new wireless/LAN connection and behave normally as it was doing in the last connection If I restart Firefox, it starts running fine
This might make sense with what I've seen of Firefox hangs with 100% of CPU. It occurs frequently when using Neopets.com on several tabs. The occurrence today happened when someone else was using our internet connection to the point that when Neopets page tried to update, the connection was unavailable. It hung for a bit, then finally returned, still using 100% cpu, and the only way to get the CPU to go down once it's that high is to restart Firefox.
