Rated 3 out of 5 stars

Latest update made conflict via All-in-One Sidebar add-on. This error message shows up when I close SimilarWeb - Sites Recommendation add-on by clicking on any button on the sidebar:

TypeError: mainWindow.document.getElementById("sidebarclose-button") is nul

Please fix it!

This review is for a previous version of the add-on (1.1.5).
