It seems that one of the open source browsers is the best bet at the moment, including Pale Moon.
YOU MUST DECONTAMINATE PALE MOON. IT REPORTS TO WEBSITES THAT IT IS MOZILLA (Firefox). BUT THE FIX IS SIMPLE:
1. Create a new tab.
2. Type "about:config" into the Address Bar as if it were an internet site (URL).
3. Type "compatMode" into the Search box that will appear right below the Address Bar.
4. On the line general.useragent.compatMode.firefox there are three settings: user set, boolean, true. Click on "true" and it will change to false.
5. Close the tab.
