The extension or a website the javascript code is injected to by metamask tried to connect to shapeshift.io which is rated "poor" by talosintelligence.com. The connection request is made approx. 60,000 times a day. The rejected connection request is not reported to the end user. The issue attracted attension to the network administration in our LAN.

Its very complicated and doesn't explain or give good directions

I really don't understand what is wrong with this extension. At first I thought it wouldn't work with Firefox Nightly or Dev etc. So I installed the stable version of Firefox with the latest update and this extension still doesn't open. It works the very first time after install and I can restore my wallet with my mneumonic phrase but, after that, it never works again. It causes more grief and is a waste of time, plenty of other serves offering very similar if not, much simpler and safer options.

This is just perfect!

Awesome

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.
