Fantastic addon!! There are a couple minor issues i'd like to report to help make it even more perfect

- When enabling the "Use larger text and menu items" option, the text of the active tab is off centered. Picture for reference: i.imgur.com/dOTqF58.png

- Some CSS codes don't seem to be working, especially the hover color codes. For example, I'm using the following

/* Active tab item, hovered */
.activetab:hover .opti_menutext {
color: #FF0532;
}

and the hover/highlight color is still the default purple instead of red

Finally, if possible I'd love an option to hide to close button on each tab for a cleaner look, or at least to change the icon to a more hi-res one (this one looks pixelated on HiDPI screens).

Thanks again for your great work!

EDIT: indeed I was missing the !important indicator, silly mistake. if possible, can i ask what is the proper css to edit the highlight color when you hover each tab? i tried every single option listed in the Helps section and none of them seemed to work
