I really appreciate Tabby for the ability to Quickly View all your Open Tabs, throughout all your Firefox Windows. As I often have upwards of 10 Firefox Windows open at one time, this Extension allows me to quickly find the one Tab I was looking for.

I do have one major gripe however, which is the reason for the 2 Stars (and apologies for that by the way). The controls and Hotkeys for Tabby are so "User Unfriendly", I just can't wrap my head around them. I've gone through the Hotkeys list multiple times. They're just not the type of controls that stick in my mind. And unfortunately, the only place you'll find the list is here, in the Firefox Add-On store (and Firefox doesn't have quick-links in the Extension Manager that can redirect you to an Extension's Page, and so you're stuck fumbling to get to Firefox's Add-On Store, and then searching for Tabby). I've been using this Extension for 6 months maybe, and every time I try to do something "intuitive" I end up closing a Tab or a Window I didn't intend to. Moving something around, selecting who knows what that went... where?

It would already be an improvement if you could find the Hotkeys list in Tabby's Options Page. And if you could customize the Hotkeys yourself, THEN you'd be set.

I really appreciate Tabby for the Visualization part. And I do use Tabby quite often for that. But as far as trying to move or change anything in the Sidebar, I try not to touch anything. It's a "just look, don't touch" type of scenario, because I just end up too confused afterwards.

I'm sorry, developer, but I've tried and tried to get a manual for this extension, to no avail. The user interface is not so obvious that you don't need one.

You say "You can even save all you windows and tabs for later with just one click!" - ok, then, how do I do that? I had a ton of tabs open, clicked on the "save websites for later", closed firefox, and when I came back there was no sign of those tabs anywhere! I'm so aggravated!

Please include documentation for your project! Your shortcuts don't help. A window is a collection of tabs? Or is that the little folder icon? Shortcut for opening last window does not work for me.

Why do you assume we know these things? Btw, I'm computer savvy, even dabble in a couple of programming languages. And yet I cannot use your extension!

Tiny pop up window. No full page tab management. Almost useless because of this.

From my experience it isn't very good. All I have seen it do is basically save a window session without much indication to be restored for later. I wouId suggest Onetab, Tabmerger or simple tab groups instead.

UPDATE Sep 22, 2022

BUG: Lost ALL MY window labels.

Started to label my windows. Did about 20-30. Then a short while after, lost all the labels (a week or a few days?)

Without the window labels become far less useful as a tool.

--------------------
Brilliant solution!

UPDATE Sep 12, 2022

2 BUGS:
- If search tabs, will only show the first 80 windows (I have 92 ATM with over 2100 tabs)
- when remove search, you can access all windows BUT the scrollbar disappears beyond the bottom of the window.

MORE Recommendations:
- when first open, bring CURRENT tab into focus (Tabs Helper addon can do this)
- when search, bring first resulting tab into focus
- default Window name to current tab of window. To differentiate from manually defined window name, make it italics or something
- option to sort named windows alphabetically
- add (x) to quickly clear search field
- STILL need speed imporovements!
(Tabs Helper addon can do much of this)

From Jul 11, 2021:

Things I really like:
- Preview feature - saves SO MUCH TIME!!! (I have HUNDREDS of tabs open... currently 1600+)

- filters out all tabs that do not match, across ALL WINDOWS!

Things I'd like to see:
- ability to choose to NOT show windows that have ZERO matching tabs

- speed improvement... not sure why speed is inconsistent... sometimes it is fast, other times it is slow, even searching for the same thing

- ability to remember the last few searches, like is a small drop-down menu

To fix:
- if start typing too soon, misses some of the characters

- settings - changing size greater than 760 x 600 creates vertical and horizontal scrollbars for the list but does not create a bigger pop-up.... Please allow pop-up window itself to be bigger...

A fantastic Addon, but as I haven't found any place I can ask questions about the Addon, I'm asking a question here. Is there any way to delete all the results of a filter in the Tabby window with just a single command? The filter is fantastic when I have multiple tabs open at the same site for pictures or other media, but I can't find any way to easily close all those tabs that match the filter, but rather have to click to close each one.

"Close all shown tabs" functionality would be an amazing feature to add to your already-amazing Addon.

Interesting functionality, but the content of the popup window is too large, while the window itsself is just too small. I can't even see 10 tabs at once ... The normal Tabbar shows more Tabs at once ...

@Dev: No I didn't find settings. I tried rightclicking the icon and looking in the addons tab, where other addons have an extra tab next to "overview" and "permissions".

Too lag.

UI is extremely slow, especially with previews enabled.

Pop-up only really limits the usefulness. A sidebar option would be great.

Very slow and takes forever to create previews. Has no progress bar so you don't know if each tab preview is loading, loaded, or anything. The window is too small as well.

Meh. Doesn't really do anything I can't already do with other extensions I already have. Additionally, the most attractive feature, which is the ability to preview tabs when hovering, is rendered basically useless since it doesn't show anything until a tab is actually loaded, and then only after you load it, move away from it, then return. Kind of pointless when FF default now is not to load any tabs until they are selected.

It's very useful, but it lacks a quick way to move tabs between windows (e.g. a "move to window" button).
Also, when first installed, it showed in the tab list a whole set of tabs that are not actually open (I have no clue about where it took them from).

EDIT: I found a new bug: it prevents tabs from auto-loading when selected. This is pretty annoying...
