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

i sign up on this a few months ago and put some tokens in it and now when l push on the foxes head just a blank square comes on. my info and tokens are gone. where did they go?

I cannot log in, the plugin closes when I click on the password.

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

太复杂，没下载明白

it is not working. Just insert the password and I can not do anything...

too confusing... maybe this is easier to use than it seems but the tutorial just confused me and I have experience with sending bitcoin and ether already. A Noob will never understand this

Sir, can I use metamask on my samsung j3 Android phone??? Please reply to mdshifur17@gmail.com
