Steps to reproduce:

1. Create a clean profile, install latest NoScript and uBlock Origin
2. Disable e10s (not reproducible in e10s mode), restart browser
3. Open this: http://geektimes.ru/company/audiomania/blog/266146/
4. In NoScript click "Allow all this page", refresh page
5. Open network console, see how 5th or so request goes to: https://vk.com/js/api/openapi.js?63
6. In uBlock Origin, create this filter: ||vk.com$third-party
7. Refresh that tab, see how no requests to vk.com are made -- this is expected
8. Open NoScript options, go to Advanced, HTTPS, Behavior, Force, and put vk.com there
9. Refresh that tab, see how a request to vk.com is made -- this must not happen, request must be blocked
