"This extension violates the Chrome Web Store policy."

[Dentorol]

This extension seems to be removed from the chrome web store. Can you fix it, please?

[darktrojan]

Indeed. I have no intention of fixing it though. See this issue on another extension for more.

The workaround for this is easy though; even I can do it. You put Chrome in "developer mode", then go to the extensions page and manually "turn on" Newtabtools with the button that "developer mode" enables the browser to have. The problem now has changed though. There are errors reported (aside from the "violation" of Chrome Store rules message) that I can't fix. If anyone knows of a solution, please, please share with us. NTT is close to extinction unfortunately, due to this conflict with the browser. I miss having it and try to find workarounds every day.
These are the current errors I see:

Unrecognized manifest key 'applications'.

You're on the master branch. Switch to the chrome branch.

You're on the master branch. Switch to the chrome branch.

How do I do that?? The question is in the wrong location, I gather. If I knew what the difference was or how to find it, I'd go there. The question is the same regardless. Please someone post material here to correct the problems we encounter with this add-on. It appears now that there is only interest in helping or promoting use of newtabtools by technicians, and it is not intended for use by non-technical workers who need the collection of links in the browser and not tech tasks to perform. Thanks.
