  • Good implementation. Right now seems to be the best balance of features & looks among the 'tree tab' extensions for firefox. Keep it up!
  • I want to know why this addon asks for the permissions it does, like "access your data for all web sites" seems very invasive and open to abuse.Appreciate it's done on your free time. Can it be made to work with lesser permissions
  • Finally, a great, simple restoration of tabs on the side for Firefox Quantum. I love it!

    Addition of compact view that only shows tab thumbnails when sidebar is minimized would be great.

    Also, I would love an option that hides the default top tab bar when side tabs are enabled!
  • One of the most visually pleasing option for vertical tabs I've seen so far. I really like the little CSS box in the preference as well as the instructions on how to write userchrome.css to get rid of the tabs. I would like to see the option to do nested tabs but this is still a great extension. Thanks!
  • Clean and fonctional. However, it is not possible to reduce the sidebar so that it only shows the tab icons, like the original tab center : https://testpilot.firefox.com/experiments/tab-center/
  • nice!
  • ideal for a big screen
  • Doens't replace the default top tab bar.
  • Nicely flexible. Open source. Friendly developer. Flexible interface. I was able to modify the sidebar colors with a little bit of correspondence with the developer despite not knowing CSS.
  • Absolutely amazing :) Thanks.
  • This extension helps to corral the forest of tabs one can get.

    However, there are a few things you'll see on right-clicking a top-tab that you won't get here: the "Send Tab to Device" selection, plus any extensions that add to the right-click tab menu (such as Foxy).

    Even so, I'll keep it in my sidebar.
  • To remove top tab bar create /path_to_profile_folder/chrome/userChrome.css and put there:

    @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

    /* to hide the native tabs */
    #TabsToolbar {
    visibility: collapse;

    /* to hide the sidebar header */
    #sidebar-header {
    visibility: collapse;
