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.

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. :-)

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.

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

Does not work as it does in chrome desktop, cannot find login page for my etherwallet, no clue given where to lok for getting started

Doesn't open

I used to manage my wallets in Brave with MetaMask plugin. Everything is fine. However, I failed to test MetaMask for Firefox on Ubuntu 18 LTS because after clicking on "CONTINUE" (Welcome to MetaMask Beta dialog) MetaMask just disappears without any notification/alert.

Seems that MetaMask beta doesn't work at all or crash. Please check.

It is freezzing up. Can not do any transactions

On 07/12/2018 my laptop displayed a notice that my "computer is slow to respond" and asked if I would like to "disable all add-ons or extensions" [I am paraphrasing here]. I agreed to this, in order to speed up the computer.
I thought I would be able to reload MetaMask using my seed words. However, when I reinstalled MetaMask and entered my seed words and my password, things got confusing. Eventually, I was able to access the account using my password, but none of my ETH or tokens showed up.

I was able to access MetaMask but, when I enter my Password [which I never changed during this process] all I get is an account having no ETH or tokens.

MyEtherWallet shows all my ETH and tokens but, they are no longer connected to my MetaMask add-on/extension.

Until this account-recovery problem appeared, I was completely OK with MetaMask. But, the recovery process leaves me unhappy and the potential [or real] loss of my ETH and tokens makes me poorer.

cant click on icon. cant access funds

installed metamask ext on firefox. fox icon comes up in tool bar but when I click it, a large window pops up but there is no dialogue in the window. what am I doing wrong. Do I have something setup wrong in windows xp? HELP!!!!
Is it possible the following is not working?
The extension injects the Ethereum web3 API into every website's javascript context, so that dapps can read from the bloc

Пропал доступ к аккаунту. При вводе секретной фразы захожу и вижу пустой аккаунт и нулевой баланс хотя в списке токенов показываются монеты которые были на старом профиле. Моя почта lifarolegg@gmail.com
