HI i switched to opera as i find firefox not good anymore and google chrome uses way to much resources, i would like to bring up the issue that Opera is chromium based browser and all of my chrome extensions work except norton toolbar and identity safe and safe search, i have norton provided by comcast, and would love to use the extensions and my password vault threw extension and such just like on chrome. Not sure what the big deal is as it is chromium based and able to use chrome extensions. please bring it to Opera thanks and have a great day.
