Is the asset store down? Is it infected/compromised?
Today the asset store does not load any the information. It stays white. I use noscript and firefox. I noticed all these new URL’s attached to unity. Was the website hijacked or is it now just full of adds and content hosted on these places?
For example: heatmap.it, bizographics.com, newrelic.com. These are data miners. doubleclick.net is malware or a google PUP which acts like malware. Did unity add these by choice and now block access to anything unless you allow all this tracking or is the store infected?
The reason for it not being loaded on Firefox is because Firefox is blocking parts of page that track your browsing. I am not sure what triggered this suddenly today (maybe an update to asset store page).
You can enable browsing in Firefox by going to the top left corner of the address bar, and you should see a “shield” icon (immediately next to the “Back” arrow button). Click on it and say disable protection for this session and you should be able to browse asset store without any problems.
