Can't adjust or dismiss sidebar -

more options

Normally I use side-berry to hold all of my tabs - the panel normally collapses and hides to the left of the screen - showing just the favicons of the website.

After the most recent firefox update 107.0 (20221110173214) there is now a large bar that i can't remove!

I have a CSS file for appearance, which i have included below.

any idea how to shrink this dead zone? I would really like to keep using my fun tabs.

****
#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {
  opacity: 0;
  pointer-events: none;
}


#main-window:not([tabsintitlebar="true"]) #TabsToolbar {

I don't use rules like this myself, but take a look at this recent thread:

https://support.mozilla.org/questions/1396856

Does that help you tweak your rules?

That solution worked perfectly, @jscher2000. simply changing my width settings header from

  1. sidebar- header {
   min-width: ~~~~~~~
   max-width: ~~~~~~~

to

  1. sidebar- box {
   min-width: ~~~~~~~
   max-width: ~~~~~~~


was enough to make my CSS work just like before!

thank you :)
