<i>duplicate of [/questions/1486143] thread</i> Dear Sir, Firefox is not working with Rabby Wallet and Metamask extensions. It does no pop-up the window to see the transaction and sign it. Firefox 134.0.1 (64-bit). Windows 10 Home. On Metamask at least I can click on the pinned extension and see the window. However it´s not the expected behavior, because it should open the pop-up automatically. With Rabby wallet it is impossible to proceed, even clicking on the extension icon. Please fix it asap.
