Everything is good except for the performance.

Really cool, I'm using it as my main tab bar, the only thing that it lacks (Or I would like it had) is the ability to change the favicon to some tabs so I can have the same page open two times with different favicons like I can change the tab title

Clicking the Add button when all tabs are cleared does not add tabs properly.

Nice! Thanks!

it's a great add-on but I'm having a problem with it.
It doesn't work properly with browser.tabs.closeWindowWithLastTab firefox preference.
I have to deactivate it first.

Please implement

Automatic groups, for example by domain

To close tabs when selecting multiple

Ability to place a new tab button in the top bar

And show an interactive animation line at the bottom of the tabs when loading

Takes some tinkering and getting used to, but helped my quitting my addiction to Arc Browser. Should inform users that you must take snapshots if you want to keep your tabs

good tree better than the firefox one

If I could name and organize the snapshots this extension would be perfect

Сойдёт но немного неуклюжее.
Имеются баги!

More powerful than any competitor, but doesn't adhere to the colouration of the system as well as http://addons.mozilla.org/firefox/addon/tree-style-tab does, per https://github.com/mbnuqw/sidebery/issues/952#issue-1592410166.

Great so far, but why can't I use the command key for keyboard shortcuts?

Лучшая панель вкладок которую я видел.

Absolutely wonderful and should come stock with every browser! However, I would really like to see a search function implemented so that I can quickly and easily find a specific tab in a window (If this option exists then I could not find it)
