Cool little helper. Informs me with the exact number of tabs open. THIS is what I wanted.
An improvement would be if I could define a number for alert notification. (even wording I enter :)
example: 20+ Hello, 40+ WaytoGo!, 60+ Caution!, 80+ Nuts!
I am at 108 right now, I need to come down.

Works as expected and the best tab counting add-ons I tried out

It perfectly does everything it should do.

Great light weight extension for those who multitask and have hundreds(sometimes thousands of tabs open). Still some "customizablity" I think could be improved in regards to sizing the font or perhaps changing the size. It is very functional as is however as is, and have been using it for a long time after relacing another tab counter. Thank you oriol.

thinks,I like this extension

Wonderful extension, thanks

Honestly, this seems to be one of the better tab counter addons on AMO... I've just been through testing about 15 of them, so I should know.

Unlike many addons on the site, the author has a very good description and screenshots and does not skimp on features.

In fact, the only thing this addon doesn't have that I really wish it did is some way to increase the font size (the *only* tab counter addon I found that has a larger font size was 'Tab Count Icon by lllusion3418' but it doesn't have as many options as this one does). I'm viewing from about 10ft away on a 50" TV set to 1920x1080. From there, TCI's font appears ~ 2x larger than TCP's. I can make both out but only just barely on TCP's.

Overall, a very solid addon. I hope increased font sizes become a thing but due to shortage of addons with this feature, I can only assume that it is difficult to do from WebExtensions. If I wasn't holding out for that or I could get me some robot eyes, then I would have no issue calling it the best one on AMO :-)

FF v89.0.2 on Fedora 33 Cinnamon

With 16GB RAM in a pc, this AddOn allows (easy use) seeing a current count of (e.g., 800+) open FireFox Tabs, both entire count and count within current Firefox window. Along with Windows Task Manager (80+% RAM used), alerts me when to shutdown some Tabs and/or reboot Firefox, to free enough RAM to avoid crashing Firefox/Windows

I vouch that it is less taxing than other add-ons, you can test it by opening "About:Performance" on a different window in a different monitor, and then opening different tabs on a different window. I also suggest highlighting Tab counter plus entry in "About:performance page.

I also appreciate that it doesn't ask for any invasive needless permissions. Kudos for that.

I like that you can choose SVG icon which shows only the number of tabs, however, the font/numbers looked too fine and small with low contrast, I changed both background and text color, but still it was too hard for me to read. Hence, I suggest to add some customization to change the SVG font values like thickness or font size. Not sure if possible, but hope so. Alternatively, add a third option to just show the WebExtension badge without the Tab icon, meaning just the number.

A suggestion, If possible add number of running tabs, meaning tabs that are not suspended. Reason for this suggestion, you can see how many tabs are running and thus help with troubleshooting. Having said that, if this might taxing then make optional.

Finally, thank you, THANK YOU for your hard work <3

It does exactly what it needs to - showing the number of tabs. Maybe it could show the index of the tab like 4/24 or something, but that's just a suggestion.

Again, otherwise, nothing to complain about. Simple and fast. Thank you for your work!

perfect except for two issues I had:
- I was unable to change the background color in the preferences for some reason
- there should be an option to not-count pinned tabs.

I hope that the pinned tab feature is added at some point but until then it still continues to be a useful and unobtrusive addon.

Seems the best option available and does not have any added permissions, but is there a way to display both current and global tab count and maybe also total window count? There are some add ons in firefox that do one or the other and some that display both current and global tabs, but none that do all three

edit: great, thanks for the update! I'm sticking with this one, cheers

Useless on dark theme, there's an open bug report from 2018 that mentions this and nothing has been done to even attempt resolving it.

The solutions are rather simple, either detect the user is using a dark theme and pick a light text colour or let the user set their own text colour.

Functionally broken on dark themes.

EDIT: Since there's no way to reply to comments, here's my reply to you Mr. Dev:
Yes, I did. You can change the badge colour but not the colour of the actual add-on window.

Before you get defensive and dismiss issues, how about you actually familiarize yourself with your own product, eh?

Here, this is the problem since you clearly can't read so good: https://i.imgur.com/KCmVv9f.png
The badge isn't the problem and not once did I use the word badge.

This add-on is simple and light, just what I needed to have in mind how many tabs I have and therefore the amount of RAM Firefox is using. Thanks!

Thanks for the addon, it's working well so far.

Have you abandoned it now, or will we see some updates soon?

cumple su cometido, te dice el total de abiertas y cuantas pestañas en cada ventana.

Works really great! It's unfortunate that the text can't be made any larger but I understand you don't have a lot of space to work with. Perhaps you could use a taller font to use up more space vertically as the text is a little hard to read sometimes. Thank you sir!

This was the first tab counter extension I've found that works on the Android app.
