same on my imac: this url will eat up a whole lot of memory: https://elements.polymer-project.org/guides/flex-layout
The only viable option is then to force quit firefox and restart it later, and close the tab containing the https://elements.polymer- project.org/guides/flex-layout url. My guess it that it has to do with shadowDom polyfill from polymer. Implementing the shadow dom in firefox would probably be the right thing to do. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1540566 Title: excessive memory usage when opening https://elements.polymer- project.org/ Status in firefox package in Ubuntu: Confirmed Bug description: When I open specifically https://elements.polymer-project.org/ and https://elements.polymer-project.org/guides/flex-layout, Firefox keeps on eating memory until system hangs.
