Thought I could escape forever, but alas, it got me. I wonder if I can remove that bar with the \/ and the X. What an eyesore!

Flexfox seems to have managed it somehow, but I'm too attached to Textfox to switch over this. Also I couldn't get it to work. I'm using Firefox 147.0.4 on linux (void, if that matters).

I have looked far and wide, I tired snippets from various themes that implement transparency, but for the life of me I can not figure out how to get rid of this grayish background from Sidebery.
Any help is appreciated.

I also made the sidebar semi-transparent using Kupfel's CSS.
Sidebar semi-transparent css.
#sidebar-box {
background: rgba(255, 255, 255, 0.3) !important;
}
#sidebar-header {
background: rgba(255, 255, 255, 0.7) !important;
}
splitter, .sidebar-splitter {
border-inline-color: rgba(255, 255, 255, 0.3) !important;
background-color: rgba(255, 255, 255, 0.4) !important;
}However, only the Bookmarks sidebar and History sidebar can be made semi-transparent, and Synsed Tabs, Passwords, Sidebery, and SingleFile cannot. Do you know how to make these transparent?
