Excellent Rated 5 out of 5 stars

I was looking for a one-click solution to enable/disable Stylish and this did the trick. (I found the code on the sourceforge forum linked in the description.)
I assigned a hotkey combination and may end up using it more than the button itself.
This really fit the bill, thanks!

Love'it Rated 5 out of 5 stars

This Addon is the best to learn programing JavaScript !
I have greater than 15 buttons of this, each one is a Mini-FF-App...

BUT it doesn't work since FF-20...

Then, I keep my FF at 19.0.2 since this addon will be compatible with FF-20+

Really need update to survive...

Buttons always stop working after I quit firefox. The buttons made only last 1 session, if firefox is closed and reopened they stop working. Can't edit buttons, can't delete them. Very un-user-friendly, need to know programming to do this (no instructions either).

Simple To Use -- And It Works! Rated 5 out of 5 stars

Worked great on Thunderbird 20 on Windows 7/64 bit. Finally, I was able to enter the code and create a button to load the Activity Manager in a new tab instead of a window.

It was also easy to create a button to load the start page, which I have as a local-disk, graphics file. Add new button > Name "Start Page" > Paste Code > loadStartPage(); > Get Button Icon From Disk > DONE! Too cool!

AWESOME! Thank you very much for creating this add-on. I use it to show the Bookmark Manager window. Here's the code:

window.open("chrome://browser/content/places/places.xul", "ac","resizable=yes,height=800, width=800,top=100,left=100")

Edit this 1 line with any of the .xul links found on this page to create some very useful buttons:

Awesome Tool Rated 5 out of 5 stars

This tool is fantastic, and keeps getting better. The current build (0.0.5.5) has a few bugs, but the dev build 0.0.5.6 fixes most of what I was having issues with. I've been using this thing for a few years and I can't live without it. I mainly use it to create custom shortcuts that I can drop anywhere on my toolbar without having the bookmarks open and hogging up space. If I could give it six stars out of five, I would. Awesome!

Great Add-on - Information could be better, though Rated 5 out of 5 stars

vasyabelkin is correct about my old review being not entirely right, although, I must say that it would certainly be nice if this came with a few more instructions on how to use it.

I don't know how I discovered that buttons could be edited by right clicking them, on my own, but if I had to guess, it's probably because I'm customizing my toolbars so much that eventually I got one of the buttons.

I find this to be actually extremely useful now, and one of my best add-ons I have. The number one thing that bothers me still is that the primary coding that the buttons are written in is JavaScript for XUL, and you haven't mentioned this explicitly.

Work excellently with Firefox 8.0a1. Finally I can give my favorite bookmarklets icons and save lot of space in the bookmarks toolbar. The only problem is that I don't know how to back up my buttons in case of reinstalling OS.

Pure Magic Rated 5 out of 5 stars

This extension has really opened up my usage of Firefox. I now have a whole bunch of useful buttons, even complete tool kits all organised on dropdown menus so that in fact I only need ONE toolbar to cover every option and extension and button that I have. (Currently over 150).The number of buttons available has increased a lot recently as has the amount of help and information available. If you want to completely revolutionise the way your firefox works for you - this is the way! What stylish does for appearance - this extension does for functionality.

Excellent!
I created individual buttons for places I go to often..
I used images from my own PC so the button is easily identifiable.

If you aren't sure how to create a new button, go to the developer's pages.
I "borrowed" some basic buttons, which I then was able to modify...creating my own. :)

I didn't have to learn anything difficult, and if you just need need basic "click the button, go here" capability, then Custom Buttons is fine.
You *CAN* get more complex control of your buttons, if you WISH, but creating a simple button is... well... very simple.

GREAT ADD-ON Rated 5 out of 5 stars

This is my favorite add-on. Many times a Custom Button can do what an installed Add-On does. A button basically uses your computer's resources (CPU and RAM) when it is clicked as opposed to many installed Add-Ons that take up resources when Firefox loads. This Add-On works fine for me in FF 3.6, FF 4, FF 5, and FF 6.0a2. The Custom Buttons Forum here:
"http://custombuttons.mozdev.org/drupal/forum/1" is the most helpful forum to which I belong. The members
there have consistently reply to my questions very promptly (sometimes within minutes of my posting). They are very willing to share their knowledge of button creation with others. Buttons created by members of that forum can be found here:
