The uc.tweak.theme.sidebery option enables the borderless Sidebery appearance. If you want to remove the shadow around the Sidebery window without using the Sidebery theme, you can disable it by removing or commenting this line in userContent.css:

@import url("tweaks/sidebery.css") (-moz-bool-pref: "uc.tweak.theme.sidebery");
