On one hand you can say my website is compatible with FF 17.0, 18.0, 19.0, 20.0, 21.0, 22.0, 23.0, 24.0, 25.0 but this seems somehow redundant. On the other hand if you just say my website is compatible to FF, there might be a version down the road on which it may not work that well. So my question is what is the best way to formally reveal that your website is compatible with most versions of Chrome, FF, IE, etc. while at the same time imply that there might be some versions with which it is not compatible. How do you do that?
You can say that "My website is compatible with all modern web browsers. However, It may not support the older versions."
