Memory consumption seems to grow linearly with time. The issue is not present in safe mode, but is present when ublock origin is enabled. It is also present when all of my other add-ons are disabled, meaning that it is an issue with ublock origin.\r\n\r\n### One or more specific URLs where the issue occurs\r\nhttp://www.meteomedia.com/mensuel/canada/quebec/quebec\r\n\r\n### Screenshot in which the issue can be seen\r\nhttp://i.imgur.com/IURu0vC.png\r\n\r\n### Steps for anyone to reproduce the issue\r\n1. Open the URL above\r\n2.

This is the case here:\r\n\r\n![a](https://cloud.githubusercontent.com/assets/585534/13552253/303c9e56-e329-11e5-90d6-a9b8f481b054.png)\r\n\r\nThe script `http://s1.twnmm.com/js/fr_ca/r1309011/modernizr/dfpad/s_code/adb_dil/adobe_audience_manager` on the page keeps creating and adding `script` tag elements to the `head` section. Blocking this script solves the issue.\r\n\r\nIt's a filter list issue, report to filter list maintainers. I did not investigate the other site, but sure it is a similar filter list issue -- sites misbehaving as a result of blocking is not uncommon, the proper step is to report to filter list maintainers."}}
