Is MetaMask risky?

I'm hearing a lot about MetaMask these days, and I'm really curious about it. But before I dive in, I want to know: is MetaMask risky? I've read about the convenience it offers in managing cryptocurrency, but I'm also aware of the potential risks involved in this space. Could you please give me a breakdown of the potential risks associated with using MetaMask? I'd like to understand things like security vulnerabilities, the risks of losing access to my wallet, and any other concerns I should be aware of. Thank you for your help in clarifying this for me.
