DevTools saved me, love them.

in macOS, Usage of CPU is too HIGH and memory leak

57.0.1 (64-bit)
Can't install because I need at least version 54 of Firefox.

Thanks for guys creating such a great tools

I want to like this one because its needed in React development! I think it has a memory leak or something it was using 10Gb of ram! i thought my computer was going to catch fire! haha Maybe i am doing something wrong. Firefox version: 56.0.2, OSX Sierra 10.12.6

I don't have experience working with react dev tools in older version of FF, but in 57 the extension is pretty slow and laggy compared to Chrome. Especially when working on some larger project.

Nice

Great timesaver when developing/debugging React projects. Thanks for adding e10s support in the latest version!
