Exactly fits my needs Rated 5 out of 5 stars

I needed a specific button to avoid repeating a stupid "move to this folder" mouse click & move.

Got the script running in 5s. Hours of productivity loss avoided. Just YAY.

Really flexible add-on Rated 5 out of 5 stars

This add-on makes Thunderbird incredibly customisable. The only limitation is the user's own understanding of XUL, which in my case is not comprehensive--but in principle you can do anything. Absolutely brilliant--and it does work with TB 45. I had been stuck on TB 2.0.0.23 for seven years because of all the add-ons that TB 3 broke, but Custom Buttons just lets you get the functionality back.

Cool Rated 5 out of 5 stars

Really useful and cool, especially if you use some bookmarks way more than others.

Rated 5 out of 5 stars

Одно из самых полезнейших дополнений в firefox. Хорошо, что вышли новые версии, а то бы пришлось искать какой-нибудь другой браузер или сидеть на старых версиях.

This review is for a previous version of the add-on (0.0.5.8.6).

Firefox 44 is started very slowly Rated 4 out of 5 stars

If there is any button, the Firefox is started very slowly for 15-20 seconds. This issue appeared on 44 version. 43 everything is fine.

This review is for a previous version of the add-on (0.0.5.8.1-signed.1-let-fixed). 

solid. Rated 5 out of 5 stars

I use some buttons since years. (Clear SearchBar, URL-Tools, Easy Reader (1-click) and some others...)

Now, with FF 43 I feel no difference.

FF is as slow as usual ;-) (Have >40 addons installed)

The buttons, I use work good, since years.

I hope, they will work a lot of years along.

confirmed slow on firefox 44 Rated 4 out of 5 stars

as said previously, Firefox start is slow due to Custom Buttons and possibly Classic Theme Restorer (deactivated on mine)
thanks for the temporary solution, waiting for official update

Firefox 44 - slow start - conflict with Classic Theme Restorer - fix Rated 4 out of 5 stars

I would bet than all who encounter slow start in FF 44 has also Classic Theme Restorer installed. According to my testing
Custom Buttons starts fast in FF 44 when I disable Classic Theme Restorer and vice-versa.

UPDATE: this fix slow starting of Custom Buttons:

Not working with Firefox 43 Beta Rated 4 out of 5 stars

Future of addon is worrisome Rated 5 out of 5 stars

Dear authors,
thank you for an excellent addon, which is a lifesaver for thousands!
But what future does it have in view of announced changes to Firefox regarding XUL removal ?

It still is working for PaleMoon Rated 4 out of 5 stars

The forums frequently have foul behavior, the site frequently goes down, a big portion of the buttons don't work- but still there are many goodies to be had.

IMO that still is enough to merit 4 stars for the capabilities that users can gain.

Nice Rated 5 out of 5 stars

The idea is great and I found istantly the button/code I was searching for.
Buttons can work or not, but it's due changes in firefox (and often, in CB site, it says what versions are supported)

Can it use existing .xml button files ? ? Rated 4 out of 5 stars

Is it possible to import a button that was previously created as a .xml file (from Google Toolbar for example) ? ? I have a few like that and when add on signing is mandatory, I will likely lose Google Toolbar (but I do have all the buttons I use saved on my computer)

Thanks

It works fine (Fx38), great forum and it has a huge database! Rated 5 out of 5 stars

It's an excellent, must-have extension! One of the most helpful forums too (http://custombuttons.sourceforge.net/forum/index.php) where people do actually help any newbie or a pro. Sometimes might need to wait a day for an answer - no prob, i guess it means those people are alive and have better things to do than hang in forums 24/7 ;-)
But they ALWAYS answer and help.
A new sortable database with hundreds of buttons (https://dl.dropboxusercontent.com/u/57898370/CB%20Database/.CB_Database.html). If you find one there that doesn't work, just link to it in the forum and somebody will fix it or will make a new button for you.
To all the 'nay' sayres, I see all that 'not working!' whining comes from people who couldn't even figure AMO is not a place for posting bugs, the extension forum is (read this site review guide just above your review textbox(!): "...Please do not post bug reports in reviews..."). Or people who appear pretty impatient, like their life depends on some browser button!
To the rest: this is one of those extensions that makes your browsing uncounted times better, saves time, space, clicks and makes you smile!

Simply Amazing Rated 5 out of 5 stars

After spending hours looking for an addon that lets me switch between global zoom levels on all tabs and none of them working the way I needed, I came across this addon.

I visited the forum and found that someone had already made a similar button to the one I needed. I installed it (which was blissfully easy) and spent about 5 minutes editing the code (again easy, in the built-in editor). Now I have a button that does exactly what I need.

I am seriously blown away.

Mozilla should make this a featured plugin, it's so powerful, useful and well made.

Thank you so much.

Rated 5 out of 5 stars

Отличный аддон! Хотелось бы, однако, одной вещи: записи присвоенных кнопкам горячих клавиш в keyconfigе, чтобы их можно было там редактировать, добавлять и удалять.
