Wow! Top!

Please add menu or button to close all tabs with the same domain or the same filter string. Really cicking "x" one by one is boring and takes long when I have >2k tabs open

I use this addons lot of time and it is very usefully when someone like to have open lot of tabs.
But discover bug. When try use "Full View window" then have a new window on windows bar but this option dont show to me window.
Few weeks ago this work ok.

When scrolling through tabs, it scrolls more than one page at a time. How can I change this to only scroll one or three lines at a time? Thanks.

Once you try this tool you think OMG how could I live without it ?!
I appreciate mainly saving my time and preventing from opening duplicate tabs. Thank you Kevin !

SO it places All tabs to a Side Window List. Too Bad doesn't Separate which tabs are in different window. IT SHOWS ALL TABS IN THE SIDE BAR.

Can't see the list of Closed Tabs &　can't Remove the Close TAB button from accidental select.

It works more stable than tree tab viewers.
But for several thousand tabs there is a few seconds delay even for several recent tabs.
Also, for sidebar mouse wheel minimum move scrolls several pages instead of only one page.

The faster it boils, the faster it cools. There were too many useless features, and it seems like burnout came in the end. I've seen many cases like this.

Must have! Really helpfull!

idea: when you open helper in separated window, it will be perfect, if focus will be in search input, so you can start typing immideately

This extension is indispensable. I use it everyday all day long and require it to keep my work organized. There is no other extension that works this well, is this reliable and provides this exceptional capability. Use it and you will see the same.

I have been using this addon for quite sometime now, and love it so so much. I would be totally lost in all the sea of tabs I keep opening without this.

It has almost everything needed to manage hundreds and even thousands of tabs. The one other thing I would love to see is an indicator showing which tabs are currently playing audio, kinda like with the native firefox drop down list of tabs. Still, an amazingly feature rich and useful addon. Thank you so much.

Works nicely, WHEN IT WORKS (Mac). Unfortunately, keeps losing the renamed Windows. Seems to occur if you disable the extension and re-enable it.

Too bad this extension is no longer maintained.

It is nice to use!

I'm really bummed to hear the dev is shutting down this addon, as it's been one of my go-to addons I've relied on for years. It provides much needed functionality for those that use a tonne of tabs.

As much as I really want it to carry on, I 100% support the dev's response. Not only does the dev using 2FA not provide any meaningful security for us users, It's absurd that after years of trusted developer provenance/relationship with this dev/addon and Mozilla, Mozilla is now suddenly saying "Give us your phone number or G.T.F.O.", forcing him to walk the plank.

Go google what's been happening with Oculus VR headsets, and what Facebook now demands from owners. You not only have to have a Facebook profile, you have to *maintain* it so that it's current, with legitimate information, and if Facebook thinks you've used fake information, they'll instantly lock you out of your Oculus until -- no joke -- you submit to them pics of your government ID's, like driver's license, passport, birth certificate, utility bills, etc. And even then, some people have reported still being denied, or at least deemed not yet sufficient enough in Facebook's eyes.

They will literally brick your fully bought and paid for VR headset if you don't surrender to them some serious privacy. I didn't believe it when I first heard of it, thinking it was too crazy. But alas, it's true. Absolute insanity. Straight out of "1984".

I see other reviewers mentioning that a phone number isn't required for this 2FA. I don't know Mozilla's 2FA specifics, but if that is the case, I'd feel much better about Mozilla requesting/demanding this measure.

Regardless, it's getting ridiculous how these companies are increasingly demanding more and more sensitive information from us: phone numbers, documents, ID's, certificates, etc. All in the name of "security".

The irony in this? In the past 15 years, I've been "hacked" more times indirectly by these numbskull companies and their obscene lapses and deficiencies in security than I have from any weak passwords or security questions or whatnot on my end. And yet they get hacked, then turn around and demand even more from us, followed by another news story months down the road that they've allowed our data to get stolen out of their hands because they stored everything in plaintext, or didn't secure this or that.

And of course they get off scot-free, no repercussions, besides perhaps providing us some "Free credit monitoring!" I have enough "free" credit monitoring from hacked companies to last me three lifetimes. I'll be monitoring my credit from the Shadow Realm at this point.

Anyway, I hope the dev reconsiders, this has really been a fantastic addon.

Like others, I was not impressed with the pop-up alert, which had more of an intrusive viral affront effect. One star demotion for that.

I am disappointed that the developer has chosen to discontinue this useful app that has been available to those who supported him for many years and came to rely on its features. Even sadder is that the decision is based on incomplete information and incorrect assumptions. As many have already stated, there are too many 2FA apps to mention that do not require personal information.

I have used several apps for various sites that only require an install, and always opted for 2FA apps that do not require personal information, including a phone number, or supplied mini al useless data. When a confirmation email is required, I use a throwaway address, now also available with Firefox Relay.

Since being confronted with this notice, I have been in search of alternative tab helper apps, so would welcome posts about any recommend replacement.
