Very useful and functional addon. Easy to use

Export function doesn't work (appears to work, then fails in the download list). Apparently it wasn't working in the same way two years ago. Can we get a fix or a way to just copy the data to the clipboard?

Funciona perfectamente. Me resulta muy útil.

Provides basic functionality for free, but requires a $10/mo subscription for business contacts and stats displays. However, you can turn to the open source FOCA software to do a better job.

It works, but costs me ~100MB memory at start and eventually ~800MB and I found this after using it for more than 2 years.

It's amazing.

Great and really useful extension, but it really slows down the loading times of pages (have had this for quite some time now, and I have reported it before if I recall correctly), and thus I sadly cannot leave it enabled.
