Pros and cons

Attribute	ChatGPT Work	Firefox
Pros	Handles multi-step work across email, calendar and files, not just chat Runs in the cloud, so scheduled tasks don't need your computer on No separate subscription if you already pay for ChatGPT Asks before consequential actions, and you can redirect it mid-task Hands back finished documents, decks and spreadsheets	Every AI feature is optional and free One switch blocks all AI, and stays off through updates Open source, from a non-profit-owned company Use the chatbot you already pay for Link previews run on your own computer
Cons	Long tasks burn through credits quickly, especially on Plus Long or complex jobs still go wrong and need checking Reads a lot of your email, calendar and chat, which some teams won't accept Only one Gmail account at a time for now	Smart Window is only in the US, Canada and France, and still beta No agent that clicks through sites or fills in forms The sidebar is just the chatbot's website in a panel Smart Window needs a Mozilla account and has daily limits A Smart Window bug pulled in browsing from before people opted in, since fixed

Who each one is for

Attribute	ChatGPT Work	Firefox
Best for	Sorting inbox and calendar admin across connected apps Weekly reports and reviews on a schedule Research that ends in a finished document or deck Repetitive web jobs like comparing suppliers or filling in forms Prep notes before meetings and calls	Keeping AI out of the browser entirely Using your own ChatGPT or Claude in a sidebar Summarising and tidying lots of open tabs (US, Canada, France) A browser not owned by an ad or AI company
