The UIFeedback extension allows Users to give feedback about the user interface. It implements two different methods:

  • a questionnaire with several questions about a found usability-flaw
  • a JavaScript-based screenshot-renderer where a user can highlight and blackout areas

The Renderer is based on the html2canvas-library by Niklas von Hertzen.



The extension can be retrieved directly from Git [?]:

  • Browse code
  • Some extensions have tags for stable releases.
  • Each branch is associated with a past MediaWiki release. There is also a "master" branch containing the latest alpha version (might require an alpha version of MediaWiki).

Extract the snapshot and place it in the extensions/UIFeedback/ directory of your MediaWiki installation.

If you are familiar with Git and have shell access to your server, you can also obtain the extension as follows:

cd extensions/ git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/UIFeedback.git


  • download the extension (will be transfered to Gerrit soon)
 git clone https://github.com/lbenedix/UIFeedback.git
  • add the following line to 'LocalSettings.php':
 require_once( "$IP/extensions/UIFeedback/UiFeedback.php" );
  • make sure you activated fileupload for the screenshots. Add the following lines to 'LocalSettings.php':
 $wgEnableUploads = true; // enable file upload
 $wgFileExtensions = array_merge($wgFileExtensions, array('png')); // add png to the list of allowed extensions
 $wgMimeDetectorCommand = "file -bi"; // have a look at: http://www.mediawiki.org/wiki/Manual:$wgMimeDetectorCommand
 $wgStrictFileExtensions = true; // http://www.mediawiki.org/wiki/Manual:$wgStrictFileExtensions 
 $wgCheckFileExtensions = true; // http://www.mediawiki.org/wiki/Manual:$wgCheckFileExtensions
  • create the table in your database
 run `update.php` from maintenance-folder

Configuration parameters


The feedback method is chosen randomly by the JavaScript code. If you want to set it to use the screenshot method only you have to set 'var use_html2canvas = true;' in resources/ext.uiFeedback.js. If you only want the questionnaire method to 'var use_html2canvas = false'
