It's excellent, but it stopped working. Normally, this isn't a reason for a 1-star rating, but... It seems the dev isn't active on the GitHub, which indicates (perhaps) that an update isn't coming soon
Thank you for your feedback, there is a new version 4.1.0 that fix the issues with the last version of Firefox (modal & icon shortcut has been disabled). You still can translate using the "new tab" functionality. Please make sure the update the addon to the last version.
