What better way to keep an eye on your inbox than with a Firefox add-on? Now you can tell at a glance how many items are in your inbox without worrying about having a tab open to a Stack Exchange site.

You can install Stack Alert from the Mozilla add-on page here:


Any platform that runs Mozilla Firefox 8-10


I can be reached at


The extension is written in JavaScript.

You can get the code here:
(look in the firefox/ folder for the Firefox-specific code)

this doesn't seem to work with the current version of Firefox. When I attempt to give it access to my account it just comes to a complete stop at the "Authorizing Application" page, and doesn't proceed any further. I tried closing firefox and clearing my cache/history/logging in, but it didn't resolve the problem. I was able to get it working in Chrome though. – Wipqozn Feb 3 '12 at 21:46
@Wipqozn: I can reproduce your problem. I will look into this as soon as possible and let you know when it is fixed. – Nathan Osman Feb 3 '12 at 21:55
I can also confirm it's error in version 10 of Firefox. Hopefully its nothing major.. – Simon Sheehan Feb 3 '12 at 22:11
@GeorgeEdison Appreciate it. – Wipqozn Feb 3 '12 at 22:16
@Wipqozn: I have fixed the bug in v0.23 which should make its way to your machine within the next day or two. – Nathan Osman Feb 4 '12 at 3:52
@George will reinstalling the plugin fix it now? (assuming your last comment means an update was pushed) – Simon Sheehan Feb 4 '12 at 4:06
@SimonSheehan: No. It has to be approved by Mozilla first. That may take from a few hours to a day or two. – Nathan Osman Feb 4 '12 at 4:24
@GeorgeEdison Great, thanks. – Wipqozn Feb 4 '12 at 14:41
This addon wasn't working for me on FF 8.x but I recently upgraded to 10.0.1 and it just started working. – slm Feb 17 '12 at 14:20
@slm: That's correct - FF 8.x is not supported by Stack Alert. – Nathan Osman Feb 17 '12 at 19:03
It doesn't work in ff 10.0.2. It always says that "an error has occurred" after I authorize it, and then it doesn't display any new notifications. I'm using linux. – Hamlet Feb 25 '12 at 22:35
@Christofian: I will look into it and let you know what the problem is. – Nathan Osman Feb 25 '12 at 22:49
@Christofian: That's definitely a bug. I'll look into it. – Nathan Osman Feb 26 '12 at 0:21
@GeorgeEdison the bug appears to be fixed now :) – Hamlet Mar 3 '12 at 16:45
@GeorgeEdison I'm still getting that bug (blank popup). – C. Ross Mar 15 '12 at 12:28

In my opinion, the icon is too large at 24 x 24. Other Firefox toolbar icons are 16 x 16. I used the following CSS in my userChrome.css file to make it the correct size:

.stackalert-button *
    width: 24px !important;
    height: 16px !important;

yeah. also, it is in topbar. why not to add an option to put on extension bar, on bottom of FF? – kokbira May 28 '12 at 17:05
@kokbira, Luckily, it is open source, so you can update the plugin yourself :). – Abel Sep 24 '15 at 22:43
