1. Не сокращаются заголовки закреплённых вкладок до размера одного значка
2. Настройка внешнего вида очень трудоёмкая

Good addon. A bit too simplistic, but at least it doesn't crash the browser, like others do.

I like the simplicity.

I couldn't guess whether overtyping 'MarkerNameHere' would (a) rename the marker; or (b) result in an invalid URL.

Also, re: https://framagit.org/ariasuni/tabcenter-reborn/issues/66 Tab Sidebar is is one of four (or more) extensions that use the same word, 'Tabs', in the sidebar.

Please, can you use a more distinctive phrase?

Thanks

Good job !
The best to replace All-In-One-SideBar. but with fewer features. I regret the opening/closing of the sidebar with mouse gestures

Good job. Lightweight. Font size is readable to me. What do I put in "Override Style Sheet" in order to get light text on dark background? Could you let me know, or else make this extension follow the dark theme that Firefox uses? Thank you.

Nice and simple Tree Tab

is it possible to hide the tabs on the top of the browser?

Great addon could you add the options on the right click context menu to bookmark the tab and copy it's url to the keyboard? Also it would be great if you could select more than one tab at a time using control or shift to be able to manage the tabs in bulk like move them close them etc but the action applying to all the selected tabs.

Thank you so much!
This reminds me about All-in-one Sidebar.
Very easy to handle Browserhistory and Bookmarks. Would be nicer if the opening button for the Sidebar was on the left side instead. Like a button in the left upper corner underneath the "back" button.
Keep up the good work.
