I just upgraded to Firefox 22 from 21 now all of my Selenium tests are breaking. Is anyone else having this issue and do you know how to fix it? Thanks Here is the error I am getting: [error] Unexpected Exception: fileName -> chrome://selenium-ide/content/selenium-core/scripts/htmlutils.js, lineNumber -> 309, columnNumber -> 8

These test were running great before the upgrade.

Chosen solution

A bunch of APIs were removed from Firefox 22.

I'm always a little confused about the various component parts of Selenium. If you poke around the site, can you find an updated version of whatever it is you're using? http://www.seleniumhq.org/

Note that you can open such a chrome URL in a Firefox tab via the location bar to see what this code is about.
View Source will make it easier to find the line number.

I am seeing consistent FF22 crashes (not selenium but actual FF22) crashes on a pass of many sites. The crash rate is 2% to 5% and is a real problem. This only appeared on FF22 with no problems in FF21.

I have sent the crash report to FF multiple times.

Hi QueenstownSwords, if you would like to get to the bottom of those crashes, I suggest posting a new question and including several recent crash IDs. This article describes how to extract the IDs, and here is the link to start a new question:

All, 3Dee here again. I was able to solve my problem by upgrading my Selenium. Fixes were made to Selenium to support FF 22. Thanks to all who made the fixes! 3Dee
