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.
