Quick & precise technology lookup, which greatly enhances my work. It quickly gives me accurate information about tech stuff I need, saving me time.

Works as expected, can't ask for anything more.

This is a neat tool but the "access every page you ever visit" permission seems unnecessary and intrusive, and it slows Firefox to an unusable crawl over time.

It also seems disingenuous that the AMO listing never mentions anything about half the functionality being pay-walled behind a separate subscription service. As a matter of fact, the listing may just be the most pathetic one I've ever seen on here. The entire description and about section consist of 1 measly sentence, all the links lazily point to the homepage for their company website, and there's 1 single screenshot from some ancient version that in no way resembles the current bloated and complicated interface.

Frankly, this listing should be reported as deceptive.

Very useful and functional addon. Easy to use

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.
