Metamask-extension: Metamask is blank in Firefox 79.0

[belgacoin]

Hello,
Browser details:

• MacOS 10.14.6 (Mojave) on Macbook Air (2014)
• Browser: Firefox 79.0
• MetaMask Version: 8.0.7 (last updated: August 12, 2020)

So, I guess after its update, my Metamask wallet went blank.

Apparently, back when I wrote down the seed words, there must have been some mistake because when restoring the wallet on another computer, an unknown address with 0 funds was showed. I guess, I mixed up something I don't know.

Thanks for the report!

How long did you wait for the popup to render? It can sometimes be slow to initialize, and unfortunately it does just show as a blank white rectangle sometimes while initialization is ongoing. At most I've seen it take a second or so locally, but it might be slower in some cases, and of course it depends on your device.

I did try briefly to reproduce this issue locally but could not.

Hi, I did leave it open for long enough time. It might be related to the update. Meanwhile I could restore it on Brave browser since Ive found the correct seed.

Same here. Restarted browser. Disabled uBlock Origin. Same "blank" window.

• Windows 10
• Browser: Firefox 79.0
• MetaMask Version: 8.0.7 (last updated: August 12, 2020)

Update: I've removed Metamask from FireFox and re-installed it. Seems to have fixed the blank issue.

same issue.
scary. firefox 80.0, ubuntu.
reinstalling didn't fix. works in chromium but I'd rather use FF.
some stuck txes earlier in the day, canceled using https://cancel-ethereum-transactions.web.app/ and custom nonce.. no issues after this... but later on, blank.

Thanks for letting us know! Could you please contact support? You can do so here: https://metamask.zendesk.com/hc/en-us/requests/new

Unfortunately we have been unable to reproduce this problem, but getting state logs should help. It would be greatly appreciated if you could contact support and submit state logs; they can walk you through the steps to get logs in this scenario.

[tschubotz]

@Gudahtt I had to already reset my Metamask since I needed it. So I assume the state logs are gone?
I'll Metamask contact support via Zendesk in case it happens again though.

[Gudahtt]

@tschubotz Yes, that is correct, the state logs would be gone after reinstalling. Thanks anyway!

[Incedis]

Thought I would add my 2cents.
Issue is fixed (at least for me) after latest update of Firefox (82.0.2-3), literally minutes ago.
What a pain not to have acces to Metamask.
PS: I am running Linux, Fedora 33. Fresh up to date.

@Gudahtt I just now ran into the issue again - blank Metamask. Reaching out to the support link now.

[tschubotz]

@Gudahtt my support request id on the Metamask Zendesk is 68274.

[tschubotz]

@Gudahtt your colleague suggest reinstalling the extension. I just thought that you guys wanted to take a look at the state logs?

[Gudahtt]

Thanks @tschubotz! The error you sent us was helpful. We got some information from another user as well, so I have a few new leads to investigate.

For everyone in the thread, can you remember what you were doing when this first happened? I haven't seen any reports yet that included that detail. I know these instances happened a while back so you probably don't recall, but if you do (or if you see it again), any additional context might help!

@Gudahtt I actually didn't send you guys any of my logs, yet. Upon logState(true) I get the error Uncaught TypeError: window.getCleanAppState is not a function. And I have yet to hear back from your colleague about this one.

I'd like to reset my Metamask soon since having to switch browsers now constantly is taking a toll on my productivity.

I'm not 100% sure anymore, but I think in my case, it happened after a browser-restart, i.e. I actually wanted to log back in to my Metamask. I don't remember the last (Metamask) action I did before that browser restart though.

Yep, this is what I meant! This tells us that something failed very early in the initialization code. This is interesting, and different from a few other reports we've seen, so we may be looking at multiple distinct bugs here.
