I don't know how many millions of times this has to be said, but here goes one more time.

This is a review page, not a bugs report or feedback section. For reporting bugs go to the official Custom Buttons forums (http://custombuttons.sourceforge.net/forum/index.php). It's right there in the description of this add-on.

In the official forum (inside the Bug report section) you will find a fixed version of this add-on that has been published there for more than two months.

For people saying "JS opens new links -- always -- in new windows regardless of the browser setting". I tell them this: JS opens new links were YOU tell it to. Custom Buttons add-on has nothing to do with that. Again, ask your questions in the official forum.

And here is my review. Custom Buttons add-on keeps working despite all efforts by Mozilla to want to kill each and every one of the add-ons that are remotely useful.
