Extension Technology Services installs ad blocking software for the Google Chrome web browser on all Extension computers by default.  This browser extension, uBlock Origin attempts to keep you safe from malicious websites, popups, and makes the web much more readable by blocking a significant amount of advertisements.  Sometimes however it can cause certain web pages to not load or cause certain elements of a web page to not work as intended.

You can see how many items on a specific web page are being blocked by looking at the browser extension's icon at the top of the browser.

This extension can be disabled on a per web page basis if you believe it may be causing an issue by clicking on the icon and hitting the button at the top of the pop up. 

Once you hit the pictured button you can reload the web page by clicking the new button that pops up beside it.

This will reload the web page without uBlock Origin enabled and will allow you to access anything it may of been blocking.
