How to use unlighthouse without Chrome

[mbnoimi]

I'm unable to run Unlighthouse in my Linux Mint 21.2 machine. I suspect -as mentioned below- this issue related to Chrome path.

I don't use Chrome and I wont. Can I use Unlighthouse without Chrome?

Hi @mbnoimi

You need Chrome installed to run Lighthouse. In v0.7.0 I've added a fallback option for it to download a chromium binary for you and use that if you're missing Chrome.

Will close for now but let me know if you have any issue with that.
