DEAR SIR, Please, excuse my poor english ... I am french ! thank you for help i give below the details you ask for ... but my question is not for my PC. It is for my phone ! That is : I AM LOOKING FOR A FIREFOX "LITE", I MEAN VERY LIGHT, BECAUSE THERE IS NOT ENOUGH MEMORY LEFT IN MY OLD SAMSUNG PHONE GT-S5830 ("ACE") TO INSTALL THE NORMAL PHONE FIREFOX in it ! IN SPITE I HAVE ONLY VERY FEW APPS INSTALLED IN IT. MY PHONE RUNS WHITH ANDROID GINGERBREAD THE APPS INSTALLED YET IN IT ARE : CAMSCANNER, NOTE EVERYTHING, RECORDMYCALL, MICROPHONE DRAGON, GO KEYBOARD (SWYPE), ANDROZIP, SMARTVOICERECORDER, REVEIL NUMERIQUE OF SQUARENOTCH, CALL LOG MONITOR, ADVANCED TASK KILLER,SMS MMS TO EMAIL, AND SCREEN OFF AND LOCK. unfortuntally I CANNOT UNINSTALL ANY OF THEESE APPS BECAUSE I NEED THEM ALL. AT THAT TIME I AM USING INTERNET EXPLORER BROWSER WHICH IS PRE-INSTALLED IN THE PHONE, BUT I WOULD PREFER USING FIREFOX ! I HAVE TRIED TO UNROOT THE PHONE SO THAT I CAN UNINSTALL THE PRE-INSTALLES APPS THAT I DO NOT NEED, LIKE "CINE", FRENCH "PAGES JAUNES" ETC, AND PROVIDE ROOM FOR FIREFOX. BUT EVEN UNROOTED, I CANNOT UNINSTALL EITHER OF THE UNNECESSARY APPS EXCUSE MY ENGLISH THANKS CORDIALEMENT

bonjour ! THANK YOU VERY MUCH FOR YOUR QUICK ANSWER I RECEIVED I have tried your proposition immediately but softonic sent me to play google, who told me that F.F. could not be used with my phone "(Cette application est in compatible avec votre appareil)" So probably it does not exist a version of F.F. that fit my phone Samsung ACE GT-S5830 ! I have a effectiv problem of room on this device. But in that case it appears that the problem is not one about room-or-not, but one about non-compatibility ! Any way thank you very much for searching a solution ! Please could you let me know if there is a solution some day. May be it is GINGERBREAD that is the problem But I do not like kitekat  ! And i do not think i could put it in my phone, because of ... room ! Some day perhaps there will be a F.F. version for Gingerbreado Au Revoir Cordialement

You could search for "Pale Moon" in the app store. It is a Firefox-based browser that is stripped of a lot of features, making it a lighter version of Firefox. (But with no Firefox sync....but you still can use Firefox add-ons)
