Maybe you have a very powerful CPU. In my tests on a i5-2500k CPU usage jumped from 0-3% to 8-10% usage, so I wasn't sure first.\r\n\r\nInstall the non-fixed version of CTR, set tab appearance to \"Curved tabs (Fx default)\", open task manager and look at CPU usage of Firefox. Then enable \"Squared tabs\" and compare the values in Task manager."}}
