Definitely enjoying this extension. In now time I am usefully moving through at least one hundred tabs spread across fifteen headings! Excellent.

Now I am looking for a way to collapse and expand the tabs so that I can just see the headings.

And a way to save then load the whole set and also just one named window, and combinations of that.

I hope I can find the answer, otherwise there is an enhancement idea :-) or two already.

LOVE IT!!

Been reluctant to rate this reincarnation of ATH after being so fond of the pre-WebExtensions versions, but getting past that, it's hard to fault this add-on or the work that's gone into reviving and maintaining it, and it certainly continues to beat the stock Firefox tab menu in functionality.

since the 'show all tabs' arrow only appears if 17 or more tabs are open, and can't be locked, this add-on is a life saver.

and it provides so much more.

it's an amazin add-on

ATH V1.2.18 (updated to 1 Jun 20)
FF V77 and 77.0.1 (updated to 4 Jun 20)
1. Since these FF updates ATH displays a blank panel, ie. it is not registering there are tabs open
2. Additionally, ATH Settings have been reset (size, theme, etc.)
Prior to these FF updates ATH was working fine. Other Add-ons are also not displaying properly since these FF updates. Another great job from Mozilla!!
ATH would be 5-star if it had a badge showing number of tabs open.

Very nice! Compact and minimal, however, it doesn't show the number of open tabs over the All Tabs Helper icon. This is a real killer. Please add this. Thank you.

"5 stars" when it shows the number of open tabs over the All Tabs Helper icons...

excellent extension! i have one feature request however- please make it toggle its light/dark mode along with the rest of firefox on mac os. you can detect whether the system is in dark mode with css- https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-color-scheme

this is relatively easy to do with user css as well- here's a pastebin with the code- https://pastebin.com/9X13BaUg
but it would still be nice to have it auto switch by default.

At the options is possible to customize the "browserAction popup" width. But please Kevin, how can I increase the pop-up height? Thank you

If you keep a lot of tabs open, this is fantastic. Fair warning: it makes it easier to have more tabs open. ;-)

My favorite extension.

Highly configurable but lightweight, with a lot of useful functionality. One of the best addons I use.
Biggest problem used to be that scrolling was very slow but most recent update fixed it, so thanks!

Some minor issues:
- Full view mode doesn't work in private windows
- When "typing initiate filter/search" is set and ATH sidebar is opened, the search box isn't automatically focused like it should be

Pretty good for working with many tabs!!

I agree with User circcc:
"Please support Speaker icon that muting/unmuting playing tabs in the list.

You can refer to the code from "see all tabs (https://addons.mozilla.org/en-US/firefox/addon/see-all-tabs/) that support it."

wasn't using this for a while and decided to give it another try. Makes no sense to me. or, shall I say I don't like it. Used it to open the menu--which one? geez, the various menus are hardly explained. Okay, opened the first--browser action popup. Great it shows my tabs. But I can't go to any specific tab WITHOUT PICKING UP THE F***ING MOUSE. I hate the mouse. Worse invention in the world. So bad ergonomically. Please, let me tab through the menu once it is present and select with enter or SOMETHING.

(if there is a way to not use the mouse, I didn't see it in the doc.)

Initially installed as an alternative to the lack of a close button on Firefox sidebar tab, it turned out to have a lot more of useful functions.
Now, I would like to know if there's an option for having the current tab shown when either the pop up or the sidebar is prompted and All is selected, because since I have an indecent amount of open tabs I have to scroll down a lot to go to the current tab. Maybe in the CSS?

Edit: Thanks! That did it!

The instructions are baffling, and need to be rewritten more simply. But the addon does the main thing I want. It provides a list of all the tabs in all the browser windows.

Let me save you some time. Go to:
Tools menu > Addons > Extensions > All Tabs Helper > Options > Appearance section.

There you can increase the "BrowserAction popup width" with the arrow to a maximum of 600 pixels. This is the width of the popup list that shows up when clicking the addon icon. This makes the list wider and more easily scannable. If you click in the form, you can type in an even larger width up to 800 pixels before the list width maxes out on my monitors: 2560x1440 and 1920x1080.

In the "Multi-window" section check the box for "Enable multi-window mode".
Also, in that section check the box for "List host windows tab first".

Those 2 changes put all tabs from all browser windows in the list. It puts the tabs from the current window at the top.

This addon is incredibly useful to gain an overview of my bucket loads of open tabs. It's stable and reliable.

One thing that does make using this addon a little bit difficult though, is the small font size, Despite having chosen the option "Use larger text and menu items" the fonts are still very small to me.

(Would anyone know if it's perhaps possible to adjust the font size myself via about:config or something? Does anyone know of a fix or hack? Anyone? Bueller? Bueller??)

A requested feature would be to be able to close tabs in the various menus and popups using middle click. (Again, because the close "x" is very little.)

Despite the minor issue with font size, I'm really grateful for this addon and it's the best tab manager I've tried. I'm giving it 5 stars because the plusses far outway the minusses and the font thing is, technically, an issue with my eyes more than with the addon itself, I guess. ¯\(©¿©) /¯

Thank you Kevin Jones, for making this addon. It's made my tab-hoarding life a little easier. :)

EDIT: (REPLY TO DEVELOPER):

Thank you SO much!! That suggestion was immensely helpful and I also managed to tweak a few other settings while I was at it! Everything is perfect as can be now. Thank you! :D

Pretty good, very useful for managing tabs. Only problem is the scrolling is a little buggy when my mouse is directly over the list. If my mouse is on the scroll bar it's fine.

It was saving my ass every day as I use to have open more than 250 pages. But last 14 days it stop to work, showing only empty list :-(

It works great BUT...

https://support.mozilla.org/en-US/kb/permission-request-messages-firefox-extensions#w_access-your-data-for-all-websites

The extension can read the content of any web page you visit as well as data you enter into those web pages, such as usernames and passwords.

EDIT:
Thank you very much for the reply.
That permission is scary, and for good reason.
I am not able to understand the source code, which would require much time on every update, anyway.
Without that permission, it would be perfect.
Even if that should require to remove some features.
Anyway, you made an open source addon which works great.
And you read the feedback.
Therefore I give you my compliments and raise the score to four stars.
I am sorry for myself, because I won't be using such a useful addon.
Thank you very much for your work :)

Awesome!!

Font-size is tiny by default and cannot be increased. Please provide an option for increasing the size so we may be able to read the tab list better.
