HTML5 Canvas Image Data Extraction




Wordpress LScache Plugin: HTML5 Canvas Image Data Extraction

Last Updated on: Wed, 15 Apr 2026 00:00:02
Hi, Why is Litespeed Cache Plugin trying to extract HTML5 Canvas Image Data? When TOR users access a website running Litespeed Cache Firefox browser shows a pop up altering the user that the website is trying to extract HTML5 Canvas data. Screenshot of the pop up can be seen here https://i.imgur.com/vlZYtCe.png Is it possible to turn this behavior off in Litespeed Cache plugin? Thank you. I have further narrowed down and the exact option that is causing this is Image Lazy Loading option in Litespeed Cache Plugin. Settings > Media > Lazy Load Image (On/Off) Is it possible to have Lazy Load Images turned on and NOT have it try to extract HTML5 Canvas Image Data? Thank you. Hi @odeskumair, yes our Lazy Loading plugin will use canvas at current version. We are going to improve this feature for supporting TOR soon, will let you know when its ready. Hi @odeskumair, Our lazyloading feature upgraded, please update to our latest version v2.8. Thanks, Stanley Many thanks guys. It is fixed.
