Regarding the pointer to my bug 1520364 (which was rightly marked as a duplicate), you might in particular want to see my suggestion for an integer value in about:config to determine whether the Tab manager a.k.a. overflow menu a.k.a “List all tabs” button should only be visible in cases of overflow (as it is now), never be visible at all, or visible if n or more tabs are present (for a positive n).

I believe that other aspects of the new proposal should be configurable in about:config too. Primarily, the change that the manager shows all tabs in all windows, not just the current one. Also, the threshold of 6 tabs after which the “Show more tabs” submenu appears. The choices in the proposal might be about right for many users, but a) users with smaller screens might need a different threshold, and b) those with a larger number of windows which they use for well-organised groups of many tabs might prefer to only see the tabs in the current window, as they might not have a problem finding the right window but would then prefer to see all the tabs in that window without having to open a submenu.

Bug 1480542 : WIP - Implement new overflow menu to permanently be visible.

Depends on D35570

Peter, can you go through and abandon all but the revision you are actively working on?

Yes, Sam. All the obsolete attachments are abandoned.

Hey! This bug was set aside for GSoC but I guess wasn't completed. Is it open for contributions?

(In reply to Mohd Umar Alam [:umaralam48] from comment #33)

Hey! This bug was set aside for GSoC but I guess wasn't completed. Is it open for contributions?

Yes. The first step is to define a new "browser.tabs.tabmanager.enabled" preference and make the necessary changes to retain the overflow menu so it is always visible (thus making it a tab manager menu rather than a overflow menu). And add a basic test to verify this works. Later bugs will cover the changes to the menu's contents.

This is not good bug to get started contributing to firefox, I suggest picking something from the list at https://codetribute.mozilla.org/projects/ff?tag%3Dgood-first-bug, and following the instructions at https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Introduction

Hi Sam, Can I work on this issue?

I wanted to work on this during GSOC but didn't got selected. So I would like to work on this bug now.

Added a preference to control the visibility of Tab Manager Menu to facilitate the incremental development.

Hi Sahil, I'm glad to see you back. :umaralam48 is actively working on this one at the moment.

:amylee, can you clarify what this should look like where there is only a single tab open and the tab strip is not overflowed? In that case the "+" new tab button hugs the trailing edge of the tabs.

Hi Sam,

The overflow menu should be permanently anchored to the far right of the tab bar (where it currently is now). Thanks

The context menu for tab manager is left to be implemented. Should a new bug be filed for that?

I think that would be bug 356980?

It is. Thanks!

There is a tree of bugs to implement the whole tab manager spec. Some remain to be filed. If you see something in the spec that doesnt appear to have a bug filed for it, feel free to do so.
