The script blocker that I use shows that "vk-analytics.com" tries to load on every page I open, even google.com, duckduckgo.com, etc. I updated to the latest version of Firefox but that didn't help. I downloaded another browser "Opera" and added a script blocker extension on it. That script does not try to load on any page that I open in Opera. What is causing this to happen in Firefox. If you navigate to vk-analytics.com you are redirected to vk.com, apparently a popular European social website.

Thank you Anna! Looks like YouTube Adblock was loading the script. I disabled it and it stopped.

Hi washicd, can you post the unique ID of that extension so the Add-ons team can consider blocking it? The easiest place to find it is on the Troubleshooting Information page. Either:

  • "3-bar" menu button > "?" Help > Troubleshooting Information
  • (menu bar) Help > Troubleshooting Information
  • type or paste about:support in the address bar and press Enter

Scroll down past "Application Basics" and "Firefox Features" to "Extensions". Then you can select the relevant portion of the table for that extension (or the entire table) -- not the entire page, please, that's too much information. Then you can copy using either Ctrl+c or right-click > Copy and then paste it into a reply. It will be a bit messy, but we're used it.

cor-el, thanks for that! I updated that flash plugin. Also, I searched for "vk-analytics" on one of the page sources while noscript was disabled and didn't find anything. I see from your post that it wasn't quite so obvious. Thanks again!
