RE: selenium Webdriver does not run on firefox v-32
Please use the below link to find the downgraded version of firefox:
Make sure that you change the option to ‘Never Check for Updates‘ from Tools > Options > Adavanced . Otherwise firefox will install updates automatically again.
In Selenium world, it is always advisable to get the feedback first before upgrading to Selenium Lib or any browser. It is better to use the stable build/version.
