OS: Win10 x64 Pro v2004
Resposively 0.7.0
Hey there,
I just installed latest version of Responsively (first time user) and I'm unable to install React Dev Tools:

Redux DevTools have been installed just fine.
I can confirm that this is happening
@jjavierdguezas am also able to reproduce, getting this error
Error occurred in handler for 'install-extension': Error: Invalid header: Does not start with Cr24

Any reason why this is only happening for this extension? 馃
@jjavierdguezas Great find! Looks like a fix went in electron-devtools-installer v3.1.1 yesterday. I'll upgrade the version. 馃憤
@Nightliss This will go live in next week's release.
Warnings loading extension at /Users/XXXXX : Unrecognized manifest key 'browser_action'. Unrecognized manifest key 'minimum_chrome_version'. Unrecognized manifest key 'update_url'. Cannot load extension with file or directory name _metadata. Filenames starting with "_" are reserved for use by the system.
v: 3.1.1
@tpikachu These are warning because those fields in manifest are not recognized by electron, but the extension should still work fine.
