chrome-show-tab-numbers

A Chromium extension to show tab numbers.

Notable features:

• This extension supports Google Chrome’s collapsed tab group feature, automatically ignoring tabs in a collapsed tab group.
• You can toggle tab numbering for all tabs or just the current one via keyboard shortcuts or the extension’s context menu.
• Tab numbers can be relative, displaying the current tab’s absolute number and indicating the position of other tabs relative to it ― how many tabs they are ahead or behind the current one.

Q&A

Q. Keyboard shortcuts don’t work on Vivaldi; is this a bug in this extension?

A. No, it is Vivaldi’s bug. As a workaround, changing the shortcut to Global will solve the issue.

cf. https://forum.vivaldi.net/topic/75247/extensions-keyboard-shortcuts-don-t-work/115

That is a known issue that can be fixed by changing the shortcut from In Vivaldi to Global.

This can have some side effects if you use the same shortcut in other programs, so it might be helpful to also take a look at this workaround: https://forum.vivaldi.net/topic/69541/guide-make-extension-keyboard-shortcuts-work-windows-10-11
