Created attachment 67140 [details] Screenshots with comments Reaching "Features" from "Home" everything looks fine, but clicking "3.5 Features" in second link bar the second green link bar with "Writer Calc Impress Draw Base Math Extensions Templates 3.5 Features 3.6 Features" bedomes a little too long with my seamonkey 2.11. Problem not visible reaching page with 50% Zoom With 200% Zoom I observe a different problem, The bar " Home ... Security" exceeds the rest of the page contents at it's right end. The "3.5 Features" problem appears in the same way as written above.
works as designed. The navigation contents get resized to some degree by removing the padding between the elements if the text doesn't fit at the default fontsize using javascript. If the browser reports wrong dimensions in javascript, this won't work. If at the minimal padding the menu still doesn't fit, it is centered on screen, exceeding the left & right margins. If you're using a larger-than-default fontsize in your browser, the text needs more space and the problem is more likely to occur. If you change zoom when the page is already loaded, the resizing/rescaling won't be applied all over again. It is only done on document load. So if you want to compare the effect at different zoom levels, you have to reload the page after changing the zoom-factor. So this is worksforme/works as designed when it comes to the visual appearance for the case that the menu just contains too many long entries. As your report only contains a "this is how it currently is", but no "this is how it should be", I'm closing the bug as worksforme.
