The long term goal is to eventually convert everything to JavaScript which will work everywhere but that is not going to happen until after the donation goal is met and that is coming at a very slow rate.
The following 3 options on Windows will continue to work.
I recommend option #1.
- If you have the current version of MS Edge (you can download it from https://www.microsoft.com/en-us/edge ) then
- click "..." from the top right-hand corner of the browser
- click "Settings"
- click "Default browser" from the left hand menu
- change "Allow sites to be reloaded in Internet Explorer mode" to "allow"
- right click any RU tab in Edge and select "Reload tab in Internet Explorer Mode"
- toggle the option to "Open this page in IE next time".
- click "done".
- If you have slightly older version of MS Edge then
- click "..." from the top right-hand corner of the browser
- click "More Tools"
- choose "Open with Internet Explorer".
- This old version of FireFox will continue to work.
