Hello!

Thanks for reaching out to us! Can you send us more details regarding your Firefox version, and which filter list you are using when you experience the page jerking issue? We will run a few test on our end and get back to you with a resolution. Also Yandex is a known circumventor of our ad blocking efforts. Our circumvention team is working on combating this. You'll also start to see an overall decrease in circumvention with the latest release. We are certainly happy to troubleshoot further with you, please reach out to us via support@adblockplus.org. We look forward to your follow up!

Thanks
Shannon
