Works great

works great and solved my problem in no time.
How about the updates? Some website requires the last version of a specific browser, otherwise they complain and stop loading the page.

Great extension. For some unknown reasons, and with Firefox ESR 52, I could not read some websites videos, with messages telling me to update my browser... This addon is a perfect workaround. Thanks.

Exactly what I was looking for. It allows me to use Firefox as another browser for sites (and only for those sites) that require IE or Chrome.

Firefox disabled this extension because according to him it is obsolete, but why Firefox does not do its own business???

Excellente extension

work well

It really works! I loved it..
