See a restaurant’s Google reviews without leaving the food-delivery page. A simple wish became a public Firefox add-on—in one continuing DeepSeek conversation.
The request was to put real Google reviews beside each restaurant on the live e-food list. The agent inspected the page and discovered its existing Google Places library. No new review backend or developer-owned API key was needed.
The first working review panel was reported about three minutes after the request. Live checks then caught a wrong branch of a restaurant chain. Reading the restaurant’s own page supplied the branch information needed for a better match.
“It has to work on Mozilla too.” A userscript was not the final answer: extra installation tools were rejected. The same conversation produced a standalone Firefox extension, its package, icons, listing and privacy text.
A request for less code cut an approximately 25.9 KB script to 10.4 KB. Actual visual feedback fixed awkward chips and navigation behaviour. A further correction replaced case-by-case patches with structural card discovery and general name-and-branch ranking.
Mozilla validation required a manifest correction. The owner handled account sign-in and two-factor authentication; the agent handled packaging and submission. A signed self-distribution release came first. Review took longer than the agent initially promised.
The public Firefox listing became available. The published signed file was downloaded and checked, and its extension loaded in a clean Firefox Developer Edition profile without disabling signature checks. The work could now leave the development conversation.
The first useful overlay appeared in minutes. Firefox adaptation, refinement and release followed. Much of the later elapsed time was Mozilla review—not six days of continuous coding. The agent also overpromised signing speed and needed its owner to stop unhelpful status polling.
Basis of this account. Original conversation reviewed from its first product request through publication, selected execution results, both signed packages, and the complete published overlay source. No raw chat or private account information is published. This is a dated account, not a live status feed.
