Firefox bug: no message when no MetaMask installed

[evdmx]

Describe the bug
When using firefox, connect a wallet button does nothing. Regardless of whether you are logged in on Metamask or not.. Understand we may not be compatible with Firefox but there should at least be a message at the top of the screen for a good user journey. Or a message that appears when trying to connect wallet. Similar with Safari too.

To Reproduce
Steps to reproduce the behavior:

1. Open Firefox
2. Click connect wallet.

Expected behavior
Should be a message to tell user to switch to a compatible browser, most sites have this at the beginning of journey or at

This issue is intermittent. I believe it occurs when not having the metamask extension installed and after installing it remains unless you open a new tab or window on the dashboard. Perhaps a simple message telling users they need to install Metamask and then to refresh or reload dashboard once installed.

we need to check why there is no message in firefox.
