What are the absolutely mandatory extensions or apps you find yourself making use of in Web3 that you did not in Web2?

As for myself?
Foxclocks
foxclocks.org/extension-help

It has been an absolute brainsaver when coordinating chats or meetings with coworkers and acquaintances around the world.

As an extension that can live in your primary Toolbar or as an independent toolbar which can be placed at either the top or bottom of the page, you choose which time zones or Cities you would like to have quick access to.

Next time you need to know whether a coworker in Australia is likely to be awake to discuss something, just activate Foxclocks from your extension bar to see what time it is there without the need for all the math.

Super useful extension!

What apps or tools have ya'll found useful in your Web3 journeys? I would love to hear about them!
