On the tabs toolbar the '''List all tabs drop-down is almost invisible''' especially if you have "Tabs on Top" until you pass the cursor over it -- even with the cursor on top of it it is still hard to see. The '''List All Tabs button''' is just a drop-drop down arrow when all the tabs bar, if you don't see it -- look in Customize (View>Toolbars>Customize), and drag the "List All Tabs" button up to the right hand end of the tabs bar. You can put Tabs back to being just above the web page content at the bottom of the toolbars with View > Toolbars > (uncheck) Tabs on Top and the button will show up better on a lighter background. You can use a Style to make the button more visible with a larger drop-down arrow and a background color. If you don't already have the "Stylish" Extension (258.0 KB), first install it. The extension is quite large, but the styles you install are very small, most consist of only a few lines of styling code. *https://addons.mozilla.org/en-US/firefox/addon/stylish/ Tabs, Enlarge list-all-tabs button * http://userstyles.org/styles/18553 <br><small>Please mark "Solved" one answer that will best help others with a similar problem -- hope this was it.</small> ---- "Make your own styling changes the way they could have been done.
