Is MetaMask safe?

I've been hearing a lot about MetaMask recently, and I'm considering using it to manage my cryptocurrencies. But before I do, I have to ask: is MetaMask really safe? I've read some reviews that praise its security features, but there are also some concerns raised about potential vulnerabilities. I'm not a tech expert, so I'm a bit worried about my funds' safety. Can you give me a breakdown of MetaMask's security measures and any potential risks I should be aware of? I'd like to have a clear understanding before I decide to use it.
