Its a very helpful addon during developing but it loads a blank screen in Ubuntu 16.04 and Firefox quantum 61.0.1.

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.

Amazing tool! I love Ethereum. But please don't use this tool if you don't understand how important it is too keep your passphrase safe. No-one can help you if you lose your keys (and that is the whole point).

It is freezzing up. Can not do any transactions

Very practical to use, as for security I had doubts, shortly after I made my registration, a transaction of USD $ 3,996.65 appeared asking for my confirmation of shipment with my balance being USD $ 0.00000.
But I rejected the transaction and even tried 3 more times. So I give 5 stars to be able to confirm or reject a transaction whatever.

Best wallet there is!

okay

太难用了
