Rated 5 out of 5 stars
Best add-on ever!
Unfortunately after updating to version 1.2.0 it's not possible to login to router FRITZ!box 7270 anymore, a click results in no action. Reinstalling version 1.1.9 fixed the problem. Firefox version 46.0.1 64-bit.
Edit: Fixed via version 1.2.1
How about 1.2.1? https://addons.mozilla.org/en-US/firefox/addon/secure-login/versions
