Tree Style Tab sidebar will not display by default when opening browser

I have two Windows 10 PCs with the Tree Style Tab extension enabled with default settings. One Firefox displays the sidebar by default when I open it, while the other must be opened each time. I've looked through the settings and can't find anything that would explain the different behavior.

I'd like the Tree Tab sidebar to always display by default when I launch Firefox. Any ideas as to why it doesn't?

Thanks

I figured out the issue: I had installed Firefox Multi-Account Containers extension add-on to the one PC. When I disabled it the Tree Style Tab sidebar again opens with launch. Must be some interaction that blocked the sidebar opening. Appreciate your efforts to assist.

Hi Mel, an extension can open the sidebar for you if it wants to. Does Tree Style Tab have an option for this?

The Tree Style Tab extension is enabled. There is a long list of options for appearance and behavior, but nothing that suggests an "On-or-Off" to open upon launch. What stumps me is that both my Firefox PCs have it installed with no changes from default. One opens with the browser, while the other one doesn't. Both are running up to date Windows 10 and Firefox 77.0.1 (64-bit).
