Mozilla firfox is the only browser which I will never use it. because of its worst services and it search engine always show me yessearches which is very bad and when I keep its search to google it again and again shows yessearches and even I delete the yessearches then it will show mysmartsearch which are bad search engines and even I use this search engine it never gives me the correct information. also the mozilla loads a page very slow even when I start uploading a photo for mail it takes so much of time which I hate so much and its preferneces also so worst and while downloading a document it never downloads through idm so I never use this software even in smatphone also.
