Pinstripe (Pinned tab sidebar) — Tom B

Inspired by Discord, moves the pinned tabs to a sidebar which is always visible. Pin your favourites and easily access them.

Firefox is limited on what you can do with sidebars, and by default enforces a very large minimum width. For optimal appearance you will need to set up your userChrome.css as outlined here: https://www.howtogeek.com/334716/how-to-customize-firefoxs-user-interface-with-userchrome.css/ with the following:


#sidebar-box[sidebarcommand="_f9a7bfdd-59d9-4740-82e4-26232256236d_-sidebar-action"] #sidebar-header {
display: none !important;
}

#sidebar-box[sidebarcommand="_f9a7bfdd-59d9-4740-82e4-26232256236d_-sidebar-action"] + #sidebar-splitter {
width: 1px !important;
border: 0 !important;
}

#sidebar-box[sidebarcommand="_f9a7bfdd-59d9-4740-82e4-26232256236d_-sidebar-action"] #sidebar {
min-width: 0em !important;
}

.tabbrowser-tab[pinned=true] {
display: none;
}
