It was super slow (thought I think that applies to CLI Codex too), it wasn't outputting any text explaining what it was trying to achieve, and it started off down a path that made no sense. Claude Code in Zed has some rough edges but it's at least usable.
In terms of GUI agents, Cursor is still a lot nicer experience, IMO. Though I do still prefer just using Claude Code cli, personally.
Imagine you have an AI button. When you click it, the locally running LLM gets a copy of the web site in the context window, and you get to ask it a prompt, e.g. "summarize this".
Imagine the browser asks you at some point, whether you want to hear about new features. The buttons offered to you are "FUCK OFF AND NEVER, EVER BOTHER ME AGAIN", "Please show me a summary once a month", "Show timely, non-modal notifications at appropriate times".
Imagine you choose the second option, and at some point, it offers you a feature described as follows: "On search engine result pages and social media sites, use a local LLM to identify headlines, classify them as clickbait-or-not, and for clickbait headlines, automatically fetch the article in an incognito session, and add a small overlay with a non-clickbait version of the title". Would you enable it?
They basically already have this feature: https://support.mozilla.org/en-US/kb/use-link-previews-firef...
