Downgrade Firefox version 38 to 35 on Mac failed even when Preferences > Advanced > Update - was set to 'Never Check for Updates' after downgrade
I originally installed Firefox version 38 on Mac but later realized that I am expected to have only version 35 for my business. I downloaded Firefox 35. Uninstalled Firefox version 38 and installed version 35. As soon as I installed version 35, I went to preferences > Advanced > Update and set it to 'Never Check for Updates'. I closed the Firefox 35 instance and removed from Dock. Later I launched Firefox 35 and went to 'About Firefox' and noticed that browser instance started downloading new files and version 35 auto updated to version 38. I repeated same procedure at least 2-3 times but no luck. I also tried using about:config option and set preferences as follows: app.update.auto - false app.update.enabled - false app.update.silent - false But no luck. Can anyone advise how to get this Firefox downgraded to version 35?

Firefox 35 is no longer supported. Is there an actual reason why you can't run Firefox 38?
I need to use Firefox 35 because we are using lower version of Selenium for test automation. We need to use version 35.
The "About Firefox" dialog always checks for updates. If you do not want to check for updates, do not call up that dialog.
