Feature Request: Add Option to Display Group Names in a Dead Spot on Firefox

[giacoro]

Is your feature request related to a problem? Please describe.
I'm always frustrated when I can't see the names of my tab groups at a glance, especially when there’s an empty space in the browser. It would be helpful to have group names visible in a "dead spot" area on Firefox, so I can quickly identify and switch between groups without searching for them.

Describe the solution you'd like
I would like an option to have the names of my tab groups displayed in an empty or unused area of the browser (for example, in a corner or a section where no tabs are located). This would make it easier to organize and navigate my tab groups.

Additional context
This feature could improve user experience by providing more visible organization and making it faster to switch between tab groups. Screenshots or mockups could be provided to illustrate how the names would be displayed.

From what I've seen addons can't place anything into the native Firefox UI aside from the toolbar button and an optional badge text on top of that button. The badge text pretty much only renders up to 4 characters, depending on their render width, according to the MDN docs.

So unless I'm missing something it's impossible to place the tab group name anywhere into the UI where reliably "nothing else" is shown.

The only way that I can think of would be a "HUD" that gets injected into the websites themselves and could be placed into a corner of the website in a fixed position. This can obviously cause a bunch of conflicts, depending on the site people are visiting and what other extensions they're using. E.g. Vimium shows such a HUD in the bottom right corner to indicate the mode it's in and for "toast" style notifications. One downside of a HUD like this is, that it can't be used on privileged sites that don't allow content scripts to be injected (e.g. local files, PDFs, some mozilla domains, about:... pages, etc.).

Due to some of these potential issues and limitations I think a content script HUD wouldn't really offer that much value for the majority of the user base.

Maybe it would help you to customize your tab group icons. You could either use a tab's favicon as the group icon or you could add custom icons. If all else fails, you could create icons that contain the group name in the icon in some form.

You could also use the STG sidebar to constantly see which group is active. You can set a hotkey to toggle the sidebar, if you don't want it to always be there. Other actions that can be bound to hotkeys could also help... e.g.: "Load custom Group" or "Open popup" (default: F8). Note that some of those hotkeys must be set through the about:addons page via the "Manage Extension Shortcuts".

You can also configure groups to prepend their group name to the window title,... but I guess you don't have a window title bar either... So that probably won't help you.

Maybe some of this information helps you anyway though.

@philg-dev Thank you! You've laid out all the options.
