Pulling a tab out of the window in Firefox causes the window it was originally in to act like it has only one tab until more tabs are added

Select a tab within a Firefox window and attempt to manually click-drag it out into a new window. The old window will sometimes suddenly show only one tab in it as if all other tabs were closed, which is fixed by adding a new tab to that window.

I can confirm that.
Would be great if one could move tabs from one panoramic view to another (in another firefox window).

I have the same issue, when I pull a tab out of the window, only 1 tab is left visible. My workaround is to click the panorama button, click on a tab and they are back.

I just noticed that this extension is not being maintained anymore. It might be time to look for a fork or something. I can give it a go when I have time.

this bug is driving me crazy every day. unfortunately had to switch to the simple tab groups because of this.
