Why isn't this a Firefox default? Rated 5 out of 5 stars
At last! Highlight-All is enabled, the Findbar and Quick Search bar are in synch, and F3 works in both.
Problems with the sidebar locking up when AIOS sidebar is on the right. It must be placed on the left. If this conflicts with Windows taskbar for anyone see bug report for a fix https://github.com/Quicksaver/FindBar-Tweak/issues/11#issuecomment-9797040
With a lot of tabs open the tabs run off the screen when AIOS is open, and placed on the LEFT side. But they fall back into place when the sidebar is closed so this a minor issue for me.
Author is very responsive and attentive. Nice guy!
