Najlepszy!

Thank you. Fast and helpful.

Does what it's supposed to do and nothing more. Neat.

works fine

Super useful for us, tab hoarders with 250+ tabs opened... This is kind of sad, but this extension is not to blame!. I recommend moving it from the address bar level to tabs strip and disabling it vis userChrome.css when you have non-overflown tabs!

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

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
