MetaMask has not performed in a manner that has been beneficial. My reason is because it has not yet delivered on the promises that it had stated prior to install, i.e. it had not delivered on the promise of things. I have been the one doing all of the work while the extension has done nothing further than make ethereum and smart contracts more difficult and complicated.
My suggestion is do not make promises that are not fulfilled and to have the extension developer take some amphetamine so that he wakes up and does his job.
I like things that actually produce results that I expect of them.

Have a nice day. :-)

Excellent new breakthrough

This is the very good.

This review is not about how well it does or doesn't work. It's just to get your ATTENTION!
Something just doesn't add up.
How can there be 416 5-Star reviews-- when there are only 182 reviews for this add-on?
Maybe there is a logical explanation, but I can't guess what it is.........
If you can't trust those numbers, how can you trust anything else?
I disabled it.

good

is ok

amazing

Je l'utilise régulièrement depuis plus d'1 an. Une des applications les plus sécurisées, c'est mon avis. Très simple d'utilisation, très pratique, transparente . Je n'ai jamais eu de soucis majeur. Je suis confiant envers l'équipe de développeur et je peux sans risque conseiller cette application

Adress given by MetaMask app is NOT my eth wallet what resulted in losting my eth's. BE AWARE and double check.

Incontournable
