This is one of the few Firefox add-ons that help me keep me sane. It does exactly one thing, and stays out of your way, but is always there in a corner whenever you need it.

Nice little addon, thx!

Like others have mentioned, 3 digits is a few too few. Can we do 5? I'd request 4 but I'm up to a 5,133 count currently and, well... you know.

works great, couldn't find it at first (it showed up to the left of my minimize button) but it works perfectly and is simplistic. exactly what i need. you can look at the screenshots on the extensions page for examples. (I shoulda done that first)

Great. Easy to see open tabs numbers.

I found out why my laptop was running slow when I opened my web browser :) i had many open tabs that i opened long ago

love it! I just wish it could handle more than 3 digits, it gets hard to see the count once I have 1000 tabs open

Does exactly what it says, nice UI and not distracting giving the right amount information without it being too much

Thanks for making this. After seeing my result I have a feeling an ADHD diagnosis is incoming. I don't think having 2,245 tabs open is normal. My tab session is a few years old. I'll give it to Mozilla, Firefox has not bogged down even a bit.

Does as it promised !

It's not something that I really need but I like having it to check from time to time.
Extremely lightweight, reports at only 80kb memory on my side and requires no permissions.

Thank you for this great simple addon !

Since my browser gets really messy very quickly, I needed a counter to know whenever I have taken things too far and this is the perfect extension to do so!

Convenient. Works well.

Does what it says and looks good doing so. I often need to open multiple links in a row and this is a good way to make sure I didn't miss any without having to count the tabs manually.
