I'm using the stock uBlock or AdBlock, and in addition, I have LastPass & Google Docs extensions enabled in Chrome. I usually have 4-5 tabs open, where two are always gmail and google calendar.\r\n\r\nNow, gmail has slowed down to almost a halt! Every click and typing event doesn't give me feedback for a second or two. CPU usage varies from 60% to 90%. If I disable uBlock, everything goes back to normal. Please let me know what I can do to help you find the cause."},"comment":{"url":"https://api.github.com/repos/gorhill/uBlock/issues/comments/77000231","html_url":"https://github.com/gorhill/uBlock/issues/911#issuecomment-77000231","issue_url":"https://api.github.com/repos/gorhill/uBlock/issues/911","id":77000231,"user":{"login":"1ny","id":841540,"avatar_url":"https://avatars.githubusercontent.com/u/841540?v=3","gravatar_id":"","url":"https://api.github.com/users/1ny","html_url":"https://github.com/1ny","followers_url":"https://api.github.com/users/1ny/followers","following_url":"https://api.github.com/users/1ny/following{/other_user}","gists_url":"https://api.github.com/users/1ny/gists{/gist_id}","starred_url":"https://api.github.com/users/1ny/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/1ny/subscriptions","organizations_url":"https://api.github.com/users/1ny/orgs","repos_url":"https://api.github.com/users/1ny/repos","events_url":"https://api.github.com/users/1ny/events{/privacy}","received_events_url":"https://api.github.com/users/1ny/received_events","type":"User","site_admin":false},"created_at":"2015-03-03T18:07:09Z","updated_at":"2015-03-03T18:07:09Z","body":"Browser: \r\nVersion 40.0.2214.115 (64-bit)\r\n\r\nActive Filter lists:\r\n My filters‎: 0 used out of 0\r\n µBlock filters‎: 133 used out of 133\r\n µBlock filters – Privacy‎: 2 used out of 2\r\n EasyList‎ (adblockplus.org): 55,707 used out of 55,737\r\n Peter Lowe’s Ad server list‎ (yoyo.org): 2,405 used out of 2,447\r\n EasyPrivacy‎ (adblockplus.org): 10,292 used out of 10,293\r\n Malware Domain List‎ (malwaredomainlist.com): 1,350 used out of 1,350\r\n Malware domains‎: 21,747 used out of 21,850\r\n Malware domains (long-lived)‎: 7 used out of 3,367\r\n\r\nCustom filters: None\r\n\r\nSettings: All default\r\n\r\nI have re-enabled uBlock to reproduce the error and give you details from Chrome's Task Manager.
