The installation page tells me persistently: "This add-on requires a newer version of Firefox (at least version 55.0). You are using Firefox 47.0." but I already have version 61

Do you have Firefox 47.0 running in the background when you start Firefox 61.0?

If not, then it is very likely that your Firefox profile has become corrupted. Creating a new Firefox profile should resolve this problem.
