Comment laisser le téléchargement de ce module accessible à toutes versions de Firefox si il ne fonctionne pas avec les version antérieure à v.58 !
Il faut le découvrir en parcourant les commentaires, lorsque, après son installation, on recherche la raison du dysfonctionnement !

Cette version ne fonctionne plus du tout pour ma configuration... Dommage.

Works great when up-to-date. Weirdly, I downloaded it first via Firefox addons and it didn't work. But after that, I went to the website, login and it said there were an new version of the addon. I updated and now it's working fine!

Doesn't work with firefox 58.0.2. By pressing Login button, it does nothing. Even with developer's proposed solution below, it doesn't work. Site is logged in but plugin is logged out and when I am pressing login with the credentials it says "Too many login attemps, please login to site to bypass"

Not much to tell. It just plain doesn't work. I installed the newest version today and nothing - it's like it isn't even there. Using Firefox 53.0.3 (I cannot upgrade FF because of the new way they treat plugins and addons - most of my plugins/addons don't work at all under Firefox's new setup.).

Edit in response to developer reply: Thanks for your reply, but I'm not going to lose 20+ plugins just for one. 57+ kills almost all my other plugins. I sure do wish I had access to prior versions of your plugin.

Working perfectly! Thanks!

For a long time, this add-on was ok. But now, despite you said, it doesn't work at all.
