Metamask + Trezor pop up window automatically closes without signing

[ChooChooCC]

When the pop up window shows up for me to sign transactions (the part where there is a green circle waiting to load), the window automatically closes before I can sign anything, and in my metamask activity it says "Failed, send X coin".

Which OS are you using?
Which browser are you using?

[ChooChooCC]

Mac and brave. The workaround I found is to downgrade to firmware 2.3.0, and reset the metamask and clear my browser cache, now it works with the older version.

[prusnak]

Brave is not supported. Please, try if this works in Chrome.

I also use the brave browser and had problems confirming a certain transaction for weeks for the same reason.

Then it worked. I used the Trezor suite (beta version) for this.

And now it does not work AGAIN.
What could be the reason for this?

The problem: the metaMask wallet I use is connected to the BraveBrowser. I can NOT open this particular wallet anywhere else because of Trezor, as I do not have the private key! :(

so I urgently need your help for this problem

@prusnak it's also broken in Chrome. I'm also a Brave user, but I just tried connecting the Trezor to Metamask in Chrome so that I can test, but the popup closes immediately before signing, and then the metamask page is stuck on the "Looking for your Trezor" screen

Im using:
OS: MacOS 10.15.7
Hardware Wallet: Trezor 1.10.0
Browser: Chrome Version 91.0.4472.77 (Official Build) (x86_64)
MetaMask Version 9.5.5

issue at Metamask:
MetaMask/metamask-extension#10896

@bradwbradw do you have any popup blocker installed like Adblock, privacy Badger etc?

[bradwbradw]

hey @szymonlesisz , I just disabled adblock, and turned off "pops up and redirects allowed" in chrome, restarted Chrome and tried again, but the problem still persists. This time, i did see the error "Device call in progress" in the metamask UI

[prusnak]

@bradwbradw Please, try the same thing in the Incognito mode of Chrome.

[szymonlesisz]

could you pls describe what you are doing step by step, bc. im not able to reproduce the issue.
From what i understand you are able to "connect hardware wallet" but you are not able to "sign transaction", is that right?
are you trying to send regular ETH or ERC20 token?

[bradwbradw]

I am unable to connect the hardware wallet again after I had removed it while trying to work around the issue. @prusnak When I click on "connect hardware wallet" in incognito mode, it just opens up a new window with the `chrome-extension://.../home.html#new-account/connect` url in regular Chrome, and the same problem happens. @szymonlesisz for steps, go to: MetaMask/metamask-extension#10896 (comment)

[szymonlesisz]

i guess this will require additional debugging so i need to ask you to do the following:

1. go to chrome://extensions/
2. disable MetaMask extension
3. enable "developer mode" (top right corner)
4. enable MetaMask, now you should see additional option "inspect views", click on "background.html"
   
5. in opened console write: window.__TREZOR_CONNECT_SRC='https://connect.trezor.io/8/'; This will enable additional logs from trezor-connect.
   
6. try to "connect hardaware wallet", you should see a lot of logs like:
   
7. right-clik on the logs and "save as", then DM me the result (szymon.lesisz@satoshilabs.com) dont worry it should not contain any private data at this point

[bradwbradw]

alright, I DM'd you the logs.

Does anyone know a workaround to this issue? Because, in the mean time, Trezor no longer works with MetaMask. Pop-up window always unexpectedly closes before allowing me to do anything on Trezor. That's the huge impediment as it prevents me from interacting with any DeFi app. Again, on Polygon, issue still persits. I'm not keen at all at moving my funds on MM. Thank you.

@faxotherapy the workaround I found is that I downgraded the firmware 2.3.0 (for model T) and it works. I have been using this firmware version for a few month and it works fine.

[bradwbradw]

Using a Trezor One firmware v1.10.0, I'm able to use it with Metamask on Windows 10 Firefox, but not at all on Mac Catalina (Chrome or Firefox) I also tend to change networks frequently too, between Matic, Binance Smart Chain, Fantom and Eth. I don't know if this has anything to do with the problem.
