Note that you can double-click the Tab bar scroll button to slide a full window width. A triple-click moves to the start and end.

Thank you for your response.

Yes, double and triple clicks worked for me great, as long as I had lets say 100 Tabs. But with 800 to 1000 tabs and even on 27' screen with big resolution it is still waste of time. By double click I am moving every 25 tabs backward/foreward... So... to get to the middle of lets say 800 tabs I need 16 double clicks... 16 full windows to slide... such a waiste of energy and time. And how much is it in the scale of the whole world? Energy and time?

Slider would solve that problem in a second.

Note that you can have a slider on the list all tabs list by using code in userChrome.css or Stylish if you prefer that.

Add code to the userChrome.css file below the default @namespace line.

This is what I use.

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

/* bookmarks: scroll bar */
#bookmarksMenuPopup scrollbox,
#bookmarks-menu-button scrollbox,
#PlacesChevronPopup scrollbox,
#PlacesToolbarItems scrollbox {overflow-y:auto!important}

#bookmarksMenuPopup autorepeatbutton,
#bookmarks-menu-button autorepeatbutton,
#PlacesChevronPopup autorepeatbutton,
#PlacesToolbarItems autorepeatbutton {display:none!important}

/* list-all-tabs: scroll bar */
#alltabs-popup scrollbox {overflow-y:auto!important}
#alltabs-popup .autorepeatbutton-up,
#alltabs-popup .autorepeatbutton-down {display:none!important}

/* list-all-tabs: always visible */
#tabbrowser-tabs ~ #alltabs-button {visibility:visible!important}

The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.

Absolutely amazing! Search function is awsome!

According to code for slider: is any chance to create addon with it? I am more than open to buy it even if such would exist. Addon proved, approved that is working - installable and safe. Or to create any youtube video how to do that and link for donation. It is one of those things "shut up and take my money" :).

Please concider this, and one more time great thanks.

It is not that difficult to create a chrome folder and the userChrome.css file in that folder with the above posted text. All you have to do is to go to the Firefox profile folder with the random name (<xxxxxxxx>.default).

• Help > Troubleshooting Information > Profile Directory: Show Folder

Create the chrome folder (lowercase) in this <xxxxxxxx>.default profile folder if the 'chrome' folder doesn't exist.

Use a plain text editor like Notepad to create a (new) userChrome.css file in the chrome folder (file name is case sensitive).

Paste the above posted code that is between the horizontal bars in the userChrome.css file in the editor window.

You need to make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userChrome.css because otherwise Windows mighty add a hidden .txt file extension and you end up with a not working userChrome.css.txt file. Just to be sure check the type via the Properties in the right-click context menu of the file in Windows Explorer.
