Tab Counter is a dead simple Firefox Add-In that does only one thing: it shows the number of open tabs you currently have loaded in Firefox. I love this.

I'll admit it, I have pack-rat tendencies. I prefer not to close a tab if I think I might need it again sometime soon. The problem is that over time, they start to add up, and this is bad for a few reasons. Firstly, Firefox starts to eat up a lot of memory. Restarting it takes a long time, since all these tabs have to load before I can do anything effectively, and it gets hard to find the tabs I'm looking for when there are so many open.

So I've given myself an arbitrary maximum number of tabs - 20. When I get over 20, it's time to start mercilessly paring down my open tabs. A quick middle click on each one that needs to die does the trick.

So how am I doing? Well, right now I've got 38 tabs open. How do I know? Tab Counter. Cool, eh? Except now you know what a slob I am with tabs. Be thankful I've not found an application that would count up how many desktop icons I have visible on my computer, and display the result in the system tray. Now that would be embarrassing.
