Rated 5 out of 5 stars

Been using now for a long time. Still a great addon!

I am now using this addon on all four of my OS's. It's still perfect, and does exactly what it is designed to do. Let you know when you've reached YOUR preset limit for open tabs, and nag you until you do something about it.

Every poor review here except one is baseless. This addon is not a popup blocker. To complain it doesn't work as one is just ridiculous. There are no "bugs" but it could use some few improvements a program not working the way you want it to is not a bug. A bug is when a program does things it shouldn't. This one does nothing it shouldn't do as far as I can tell. I don't even understand the suggestion to put a warning dialog in it. It has a warning dialog. It opens by default unless you set it to silent mode, gives you a list of all open tabs in all windows, and allows YOU to choose which ones should be closed.

Some added features might be nice, but frankly I don't think they are a good idea.

@ the developer: If I were you I would ditch silent mode altogether until you get it working in a more sophisticated manner. (with settings we can set to determine its behavior). I know that could be complicated and probably tend to be buggy. I would just get rid of it.

@users considering this addon: Keep in mind that tabs ARE windows. There is no difference. The only difference is in how they are displayed. Therefore, "windows" and "tabs" within this addon are the same thing. When the alert pops up, you get list of ALL tabs in ALL windows. It doesn't differentiate between tabs in one window or another. You've got to READ the list, and THINK.

This is not a lazy man's addon.

It is a simple way for you to limit your own sloppy behavior, and nag you to clean up after yourself.

It also a fantastic tool for Administrators. Install this thing on all your department computers, set it to "Force" and set a password. It'll force your users to clean up their acts, and quit wasting your time complaining their programs won't respond.
