Screenshots

Desktop:

• macOS Mojave 10.14.6
• Chrome 83.0.4103.106 (Official Build) (64-bit)

Additional context
The Agent app requires Frame, which conflicts with Metamask, making it impossible to keep using Metamask.
Disabling Frame extension and reloading the page makes Metamask work again. Enabling and reloading breaks Metamask.

This is also related to #1389, where we don't detect a non-Metamask injected provider very well. In this case, if you have the Frame extension enabled, that first panel should show something like Frame (extension).

However, it should be noted that if you want to use the Frame extension, you should also disable Metamask. Only one injected provider should be active at a time.

Hi @sohkai, if it is implemented like you suggested, it would look like the following, i.e. Frame and Frame (Extension) would show up and clicking on any of them would connect Frame. Wouldn't it be preferable to hide one of these buttons?

[sohkai]

Yes, true—we could hide the button for the extension in that case!
