see here:

Also having the same issue. Won't load on the sample github.io pages either.
Is there a way to lock out updates?
I really would rather stay with a stable version and not be "pushed" updates
I just checked out 2.1.0, and built the extension and installed as a unpacked extension for now.
ok tx.. I'll wait for the fix
@zalmoxisus: What do you think on having some sort of different channels (stable vs "canary") for the extension? Maybe publish the _canary_ one as unlisted so that anyone searching through the chrome web store doesn't install a not stable version.
That way we could have feedback, from people who actively follow this project and opt-in for it, if there was some breaking changes. 馃挱
... broken here too. Built and running 2.10
Saving a the time of others who may need to build this. Here is a zip of the unpacked build of 2.10
Also experiencing this problem (v2.2.0.2). Console has the following error (possibly related to #147):

Looks like a typo in App.js
localStorage.getItem('monitor' + monitorPosition])
------------------------------------------------^
But I've also had some issues with the remotedev-app package when trying to build this version of the redux-devtools-extension. For one it's failing linting on prepublish
Same here - breaking ...
ouch 4 hours later... found this issue :-(
@nickw444 the build only work in external window not in the chrome dev panel. is that chrome thing for unpacked extentions?

Sorry about that.
@tomchentw fixed it in #151 also added ESLint prebuilt tasks to avoid such cases.
2.2.0.3 is published on Chrome Store and should be available in about an hour.
@born2net,
Is there a way to lock out updates?
Yes, you can clone this repository and build it.
@yarcub,

Extensions from Chrome store are autoupdated by Chrome automatically. There's a way to make a new release available only for a randomly selected amount of people, to get the feedback, which should help in such cases. Though much better would be to have good tests here, so I wouldn't have to check manually every PR.
@zalmoxisus again thanks for all your work
