Hello Sebastien, Recently I notices huge performance degradation in FF in our application. After some investigation I found it is caused by EmoticonsBehavior.
According to github original JS plugin was not maintained for a long time But there is a fork: https://github.com/Caerostris/css-emoticons After switching to this new JS library performance degradation was fixed. I would propose PR with changes, but new JS version is no more jquery.plugin, just JS library ... Should I create PR, Or maybe EmoticonsBehavior should be dropped in wicket-8 version of wicket-jquery-ui ? -- WBR Maxim aka solomax
