It does what it says it does so 5 stars!

I have a tendency to build up many tabs at once. My max has been roughly around 200 tabs open at once.

I was curious today and found this extension to check my current number.. I have 470 tabs open.......

I think it's time to clean some out.

Since I keep a number of tabs open and can't find a post v57 extension that lets me keep multiple rows of all open tabs, its easy to get lost when tabs are scrolled horizontally off screen. This is a handy little reminder there are out-of-sight tabs.

Note, waterfox (branched from FF v56) supports all legacy functions and extensions, including an extension to use multiple tab rows & also to place tabs below the bookmarks (vastly clearer UI I can't understand why FF v57 dropped). Try Waterfox for support of all modern add-ons and all your favorite legacy ones. It shares the profile with FF and gives you back your old favorite add-ons and more.

I'm all about the simple yet highly effective tools. It tells you how many tabs you have open. That's it. I'm always surprised to see that I keep so many tabs open. Now, when I see a high number, it reminds me to pare down and close a number of tabs.

Like others I tend to accumulate a lot of Tabs as I browse and I find this Add-On to be very useful in helping me know just how many are open.
It's also reassuring to know that it doesn't require any permissions.
I read earlier that the Tab Count font size could not be increased due to Firefox's developer restrictions and so I have chosen to have red text on a white background for increased readability as was suggested by the developer.
I like the fact that the counter updates in real time eg. when I issue a command to Close tabs on the right, I can keep an eye the count as it decreases (my tab count can be quite high).
In these days of increased RAM and increased Tabs, this extension genuinely fills a gap.

Great extension, it helps me a lot to see my work activity. It shows only 3 digits for tab counter which is not enough for me. If more than 2500 tabs opened it slows down browser when I'm shifting between tabs and it's slightly annoying.

It has a Major problem but it is a great concept IF FIXED. The button show open TABS, this page and TOTAL TABS ALL PAGES.
BUT the FIELD IS TOO SMALL. I have 53 tabs in ONE WINDOW. IT should show "53/53" but shows "53/5" because the FIELD is too small. It is "FOUR DIGITS" Wide but needs to be "seven" to display "101/125" as example".

Does exactly what it says. 10/10

Really well executed extension. This thing stays out of the way but lets me know how things are going. On browser restart if you have 70 to 700 tabs it takes a while to catch up and there is some update lag when you delete tabs to clean up but that is most likely not a problem with this extension (more like a problem of having too many tabs open :-)).
I have a list of 7 extensions I always install and this is number 3!

Simple tab counter you can drag and drop anywhere on menu bar and customize the color scheme too. Does what I wanted it to do.

It is ok, colors can be customized, what it shows, number of tabs, number of windows, etc, also can be customized. But nowhere I can choose the place, it always sits in the tab bar, I can drag it in the addon bar with the customzation firefox menu, but impossible to put it next to the URL bar.

Works great! But how can I add the badge to the titlebar as in your screenshots (FF62)?

Now I don't have to COUNT how many tabs I have open but just with a look can see that I have 31 tabs open and I should go through them and close some. Thanks! :) What I like about this one more than the others is that it is by the tabs so doesn't make the spot with the other addons longer.
