User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0 Build ID: 20150108202552 Steps to reproduce: I updated to Firefox 34, where the default search engine was changed from Google to Yahoo. I had to re-set the default search engine to Google, and I removed all other engines from the suggestions or the dropdown list. Actual results: Upon updating to Firefox 35, the search engine had once again reverted to Yahoo, even though I unchecked it and had previously selected Google as my search engine, and removed all other search engines from the suggestions list. Expected results: Once a user sets a default search engine, it should *never* be changed by the browser, even on version update. If settings revert to default after every automatic and unpreventable update, then you have a serious bug. The engine should not have even been switched to Yahoo in Firefox 34, even though it became the default; user-set preferences should have remained. Always opt-in, never opt-out.mozilla.
