Problem with new version 1.5.4 Rated 4 out of 5 stars

I have a conflict with the extension "Toolbar Buttons 0.6.0.8" (click button "bookmarks menu")
When choosing any bookmark menu is doubling all!
Please fix. In the previous version everything was ok.

This review is for a previous version of the add-on (1.5.4).

This occurs only with Ctrl-click (not middle-click) and was a known issue listed on the Stay-Open Menu website. I have added a mention of this to the release notes. It was working properly with the previous version of Toolbar Buttons. Fix is on to-do list.
