Hi. I've been experimenting with MrOtherGuy's vertical tabs script. I found that the tab bar could be moved to the right side of the window with just two simple changes:
change line 19 from: margin-left: var(--uc-vertical-tabs-width); to margin-right: var(--uc-vertical-tabs-width);
and
change line 31 from: left: 0; to right: 0;
Works for me.
Line 39: @media (-moz-bool-pref: "userchrome.vertical-tabs.on-right.enabled"){
This line doesn't work for me, even though I have set that preference. If I comment out this line (and its closing brace), then the code block does work correctly--it just doesn't recognize the preference. Could it be because I'm testing on FF 115 ESR?
In multi-row_tabs_below_content.css (a commit from June) this line:
Line 239: @supports -moz-bool-pref("userchrome.multirowtabs.static-menubar.enabled"){
and its code block do work correctly for me.
Back to vertical_tabs.css, I tried using @supports instead of @media, and that did work.
