Broken and Discontinued Rated 1 out of 5 stars
I can only assume from the lack of communication and updates, that the developer has ceased work in this add-on.
I remember back when I first started using Firefox, this add-on was one of the first I ever installed. Since then, it has become very buggy with the most recent firefox versions and other add-ons, and it will unfortunately break completely starting with Firefox 25.
I have since written my own add-on, called "FindBar Tweak", which was greatly inspired by this and other add-ons. Unless work is resumed here, I would invite everyone to switch to FBT, it does everything Find Toolbar Tweaks does and much more and ensures it will remain compatible with future versions of Firefox! Note: there are a couple of features that FTT used to do that FBT doesn't do yet, such as moving the find bar's close button, or notifications when search wrapped. These specific features will be added in a future version.
I'm sorry for the spam, but I believe my add-on now becomes a necessary alternative to Find Toolbar Tweaks, which will stop working completely in the very near future.
