Firefox Quantum Update

[alankchan]

Please update your plugin for compatibility to Firefox Quantum. Yours is the last plugin in my legacy extensions list left to be compatible with the new Firefox version.

Not an ideal replacement, but you could use a bookmarklet similar to the following:
javascript:(function(){ var link = document.createElement('a'); if (typeof link.download === 'string') { document.body.appendChild(link); link.download = document.baseURI.split('/').pop().split('#')[0].split('?')[0]; link.href = document.baseURI; link.click(); document.body.removeChild(link);} else { location.replace(uri);}})();
