Tabs Outliner for chrome/edge is far superior than any other tab extension, and I've tried nearly all of them.

Looks like a separate window, so clearly not superior to Tree Style Tabs in Firefox.

Unfortunately due to limitations of chrome's extension model, there is no way to have a built-in extension sidebar like on firefox. I just manually position the tab window next to the browser window and it's fine. The window sizes are remembered and so it's really a non-issue.
