Never built an extension, Claude made them a Firefox chats organizer
An unwieldy pile of Claude chats sent the writer looking for an organizer extension, but the only one they found was Chrome-only. Claude built one from scratch for Firefox instead.

“I've never really used JavaScript, let alone created a Firefox extension before, but in a few minutes I was iterating on one, figuring out how I wanted it to work with Claude, and now I have a very nice and featureful chats organizer.”
Spotted: found in the wild. Details are as reported by the source above and have not been independently verified.
What they did
Facing an increasing, hard-to-navigate number of Claude chats, the writer looked for an extension to organize them, but only found one built for Chrome, and they use Firefox. They had Claude look at porting it, and Claude suggested building an extension from scratch instead.
How it went
Despite never having really used JavaScript or built a Firefox extension before, the writer was iterating on one within a few minutes and ended up with what they call a very nice and featureful chats organizer.
Try it yourself with Claude
I want a browser extension to organize and search my growing list of chat conversations. I've never built an extension before, so design it from scratch, explain the pieces as we go, and let's iterate until it works the way I want.
A starting prompt written by Agents in the Wild. Fill in the [brackets], and check what the agent does before it sends, pays for or deletes anything.
Apple's built-in capture can't record the Mac's system audio, OBS felt clunky and Kap seemed untrustworthy. So they asked Claude to build a native app that did exactly what they needed. It took 4 minutes.
Mood, food, habits and sleep, logged daily for months. A Hermes agent writes end-of-day reports (they miss a lot), but asking Claude for correlations surfaced a pattern they'd never noticed.
It built the game from his description and kept adding his ideas. Then the file got too big, edits broke in a loop, and the parent had to step in: split the code into several files.
Alarms and reminders are easy to ignore. Claude built a Twilio script that calls before important appointments, reads out the message, and won't stop until they confirm. Set up in plain English.
Linux config files are where switching gets painful. Claude helped them pick Fedora, answered every setup question and had Claude Code write the scripts they'd never have bothered with.
