Shortly after installing FF29.0 I noticed that the bookmarks menu from the 'Menu Bar' - NOT the new one that appears on the right of the screen - was not working correctly: specifically, when right-clicking on a bookmark to look for 'Open in a New tab' all the options were greyed out and I now realize that this occurs after exiting the 'Customize' screen, which effect I have consistently duplicated several times now; to restore functionality I have on each occasion had to close and re-open Firefox. This error does not appear to occur with the new bookmark menu that is associated with the bookmark icon at the top right of the screen. Has anyone else noticed this error? (Personally, I prefer the bookmark menu from the menu bar, which incidentally I find easier to read than the new one and I like menu bars anyway.) Many thanks.
