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."

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!

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

Awesome!!

This is what I wanted. Just a way to see all my tabs organized by window, and click on them. I use it for finding windows/tabs I'm looking for, checking if I still have them opened, and looking for windows I no longer need and can close. I tired also TabSearch which is good (if you remember enough of what it's called to search for it, but does not give you an overview) and Tab Session Manager (which also saves them, which I guess is good, and you can list the most recent save, or do a save right now and it will list it, but small window, lots of scrolling, and you can't navigate to them from that list). So All Tabs Helper does what I want.

Original review Aug, 2019.

EDIT 04/11/2020: I use this ALL the time. It's a workhorse. I currently have open 679 tabs in 172 windows! (679/172)

Bonus features I've discovered:

1. Right click on the window title and change the title. Helps keep organized. I found this by accident.

2. I'm using the Windows 10 "desktops" feature. Clicking to select a tab opens it even in a different desktop.

REQUESTS (Because there's no use looking for another extension that has all this plus the few things I need):

1. I have 172 windows. The windows-only view of the pop-up lists only about 30. I can't scroll it. The full-windows view does provide a better overall overview, but does not have an only-windows view. I need a way to see all my windows so that I can name them uniquely.

2. Now that I've started renaming windows, it'd be nice to search by window name as well.

3. The feature of hovering over a tab and it showing the full title and full URL is not working for me. Nothing pops up.

But I can't complain. This All Tabs Helper is true to its name. It helps me A LOT!!!

Huge productivity bump with this add-on. Nice work!!!
I'm using the shortcut to show the browserAction popup and "typing initiates filter/search" to easily track down tabs. One addition that would make it entirely mouse-free for me would be to have up/down arrow keys scroll through the search results in the browserAction popup; Enter selects (goto) the highlighted tab. Is this possible?

dups and mini window is super, maybe only the icon ;-)

F*in usefull, I almost had to develop it to solve my problem.
Big thanks!

I tried out 8 or so tab list addons, this one is the best!

Any chance of a dark theme icon in addition to the dark themed list? That white 'A' is distracting.

One of the best add-ons. Though, a close-all-dupes button would be nice.

This add on was very useful until it disappeared because firefox says it needs to be signed now ... Please update that?

I love this addon!

Bug: Versions 1.1.8 - 1.1.12 (so far). Firefox 52 ESR

Entire browser locks up when ATH toolbar button is clicked. Had to downgrade to 1.1.7. Tested with Firefox 59+ and v1.1.12 works OK. (I will stick with Firefox 52 though.)

This addon is great and absolutely neccesary, but for me one thing is missing - could you please add a button in the search field to clear it (using mouse click)? It would be perfect :)

how does it get favicons? it looks as if it's downloading them...

it would be nice if the search box was focused, so that one could hit a hotkey and start typing to find tabs

Edit: Thanks! That's great news.
Typing initiates filter does not work on Waterfox, but it does on Firefox 60, so I guess I am out of luck :(
Open Sidebar is the only action for which hotkeys work, both on Waterfox and Firefox 60

Edit2: Ideally this addon could be used entirely with the keyboard; shortcut to open pop-up menu, start to type to filter tabs, arrow keys to select tab, del to close tab, enter to open tab.
Unfortunately none of these features work.

Really useful Addon - All-Tabs-Helper allows Firefox users to keep track on all tabs and (Windows) devices.

Through the Firefox SyncTabs addon, you can also keep track on remote devices and pull everything together - only downside to date is that I cannot find the equivalent on Google Chrome.

Many thanks indeed to Kevin Jones for All Tabs Helper!

KR Andrew Ross ;-)

This addon is the reason for me to install firefox. I couldn't find search in open tabs feature on any other browser. Functionality in this addon should be added to browser vanilla versions.
