Memory leaking under Firefox

[poorbug]

1. I run npm run dev and visit localhost:3000 with Firefox(53.0.3 (64-bit)). Everything works fine so far.
2. I open the Inspector and wait about ten seconds. Then it starts leaking.

I am trying to find out what's wrong but still not found.

Latest news:
opening http://localhost:3001/dist/main-ed4a12b31ee841067274.js in Firefox caused same problem.
And I get lost. 😩

can you take a look at your redux devtool output? I had discovered some unusual behavior recently that may be related to your issue

Hi, @PhilNorfleet

Thanks for your reply.
Been busy these days. I've checked the redux devtool, but nothing strange found.

More information about this issue:

1. Just happens under npm run dev ( works fine in production)
2. Just happens under Firefox inspector ( works fine under Firebug)
3. Memory leaking until Firefox crash

How to reproduce this:

1. npm run dev
2. visit localhost:3000 in Firefox
3. open Inspector
4. wait for 30 seconds
