hey @javiergarciavera I tried reproducing your bug on Firefox but without success. I’m on the main branch. Here’s a video link. Can I ask for confirmation?

After importing an ERC1155 NFT on Sepolia using MM in Firefox, NFT Modal still doesnt close automatically. Doesnt look to be present in Chrome/Brave when replicating. No issues with ERC721 NFTs
