Another user said this, but I'm going to echo it -- Firefox opened up the LLM chat sidebar one time. I closed it. It's stayed closed. It hasn't asked me to open it again. I don't understand the hatred for something you can just _not use_. People will use it if they want to. Firefox also has a very tiny market share in comparison to other browsers.
I need things I don’t want to use to not appear in the UI.
I don’t fill my house with tools and products I don’t want and I’m not willing to have them on my computer screen either.
