I greatly appreciate the dedication and skill of the developer, yet this add-on grealty lacks in documentation.

Having disabled the chronicle in firefox there was no add-on icon and no error message whatsoever. I wasn't even aware there should be one and could not set up the new tab url.

I already quit on Firefox out of sheer frustration, but the next day I realized BY CHANCE that the error was in disabling the chronicle.

Sorry to be blunt, but software without documentation is a job half done. If you really want to help others, tell them how to use that nice add-on of yours.
