''<p>G S [[#question-1565457|said]]</p>'' <blockquote>Im having a difficulty making Foxfire my default. Ive tried the written way to make it my default, but unfortunately Ive been unable. Would you help me out please? </blockquote> Since you posted in the Firefox for Android section. If you are asking for how to set the Firefox web browser as the default web browser on Android then see https://support.mozilla.org/en-US/kb/make-firefox-default-browser-android If this is however about search engines well Firefox is a web browser and not a search engine. For how to change the default search engine in Firefox see https://support.mozilla.org/en-US/kb/manage-my-default-search-engines-firefox-android
