Running the site locally from disk doesn't have this issue. /tmp$ wget -p www.matnasim.org.il /tmp$ firefox www.matnasim.org.il/index.html … But after linking it to my webserver running on localhost the issue reproduce again. /tmp$ ln -s `pwd`/www.matnasim.org.il ~/public_html/ /tmp$ firefox http://localhost/~username/www.matnasim.org.il/ Than I've replaced the line in the code that mention jquery 1.3 with 1.8.3 which is currently the latest, and the issue still exists. <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> (More information here: https://developers.google.com/speed/libraries/devguide)
I suspect that the following site has the same problem: http://tovana.org.il/he/schedule/icalrepeat.detail/2013/05/02/4849/47/-mbsr- (Originally reported on http://input.mozilla.org/opinion/3536220)
nothing apparent which would be weird.
