I was ready to ask you about details and then my Firefox on i7 froze as well. What a horrible website, it makes gazillions requests to github simultaneously. Perfect example of Javascript abuse worthy a simple static page to me.
Ah, so I won't bother allowing js then if it's going to crash my browser. Thanks for the heads up you two.
ublock block count is 94 on my machine. Seems pretty high for a .gov site.
