What better way to keep an eye on your inbox than with an Opera extension? 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.


GPL version 3


You can install the extension from the link below until I submit it to Opera:


Any platform that runs Opera (tested with Opera 11.60).


I can be reached at


The extension is written in JavaScript.

You can get the code here:
(look in the opera/ folder for the Opera specific code)

i have Opera. No instructions on what to do after download. – Michael Durrant Apr 23 '12 at 0:25
You should be able to install it by clicking this link. – Nathan Osman Apr 23 '12 at 2:06
Clicking on Authorize Extension doesn't do anything. What should I do now? – toscho Apr 30 '12 at 20:55
@toscho: Temporarily turn off your popup blocker (and possibly restart Opera after turning it off). After clicking Authorize, a new tab should pop up showing Stack's external authorization page. You can turn it back on after authorizing the extension. – Mihai Limbășan May 2 '12 at 11:50
I had to click Ctrl+Shift+Click to get the popup in the background. Works now. :) – toscho May 2 '12 at 15:45

@GeorgeEdison thanks it works very well! – user34295 Jun 7 '12 at 16:48
Thanks for this opera extension, it should be placed on Opera site so it can be updated automatically. – PHPst Aug 22 '12 at 18:19

Still throws a 404 for the Opera extension link, though thanks for providing it for pre Opera 15, some of us are "stuck". – SEoF Jun 3 '14 at 15:37

When trying to authorize extension Opera crashes.

Edit: Opera 12.12 OS X Lion 10.7.5

When I click on the extension install link, I get a download prompt for a .ZIP file: enter image description here

I have to rename this file to .OEX and open that file with Opera to have it install the extension.

This is definitely a misconfiguration with my web server. I'll let you know when I have it fixed. – Nathan Osman May 1 '12 at 17:47
This has been fixed now. Please let me know if you have any further issues installing this extension. – Nathan Osman May 1 '12 at 19:59
@GeorgeEdison Seems to be working fine now. Thanks for that. Also, please submit Stack Alert to the Opera Add-ons site. – galacticninja May 2 '12 at 3:39

George, I have downloaded and installed successfully in Opera but can't authorize.

I can't get past :

This app needs these permissions * Perpetual access to this data * Read access to your global inbox * To know what your accounts are on the Stack Exchange network

You need to login to authorize this application.

What do I need to log into and where do I find these permissions?

You will need to log in to the Stack Exchange network - and the permissions will be granted when you allow the application to access your inbox data. – Nathan Osman Dec 27 '12 at 0:14
Thanks George, I'll give it a try. – Beetroot-Beetroot Dec 27 '12 at 0:17

I can't get past "Authorizing Application" screen.

Opera 11.6, Windows 7

I get the same auth issue.

You need to login to authorize this application...

I have logged out and logged into Stack Exchange no difference? What is the resolution for this??

share|improve this answer
Resolved. Had to setup a Stack Exchange account, as opposed to the Stack Overflow account I use which then works – StuartM Feb 4 '13 at 23:43
