ReactJS chrome extension installed but not showing up

Question

Anyone know why the ReactJS Chrome browser extension isn\'t showing for mein dev tools? It\'s installed, at one point it was working.

I\'m using chrome Version 39.0.2171

Answer 1

Restarting Chrome after installation seems to help, apart from the other answers.

I couldn't find any info on that step in the Chrome Web Store or when clicking on the plugin, so just leaving it here.
