about:bookrect - Bad URL
Bookmark Tab 4.2.1 + Firefox 45.0.2
Thank you

When you run browser - bad
Refresh the page - it is started
This only occurs at start

chrome://bookrect/content/index.html
the empty window with settings "Bookmark Tab" opens

hi serzh,

thank you for your message, your feedback is highly appreciated. i am having trouble reproducing this error though, have you tried uninstalling and then reinstalling the addon?

thanks again - coderect

edit: since you provided more information by know, i might know what the problem is. when firefox is started, it does apparently not immediately allowed extensions to add custom urls. you can therefore try and use this one instead: chrome://bookrect/content/index.html
