Mozilla Ihlala inxulunyaniswa nembali yesoftware yasimahla nevulekileyo, ukusukela oko yavela kumalungu eNetscape. Xa ngo-1998 ikhowudi yesikhangeli sewebhu esidumileyo nesiphumelelayo iNetscape Navigator yakhutshwa kuhlobo lwayo lwe-4.x kwaye iprojekthi yeMozilla yavela kude kube ngoku, kuninzi okutshintshileyo kwaye kwaqhubela phambili. Ukusuka kwimpumelelo yemveliso yayo ephambili, iMozilla Firefox, ezinye izinto ezifezekileyo kunye neeprojekthi zongezwa kwinkampani.
Ngoku isuka kwi- IMozilla Foundation (eyaziswa ukususela ngo-2003) iyaqhubeka nokulawula nokukhuthaza isoftware ekhululekileyo nevulelekileyo, kwaye bakwenza oko ngeeprojekthi zabo kananjalo ngokusebenzisana kunye nokunceda abaphuhlisi abazimeleyo nabangabaziyo ukuba benze ngakumbi kolu hlobo lwesoftware. Umzekelo woku libhaso le-500.000 yeedola zeeprojekthi zomthombo ovulekileyo oya kunikezelwa sisiseko sokunceda ngemali kunye nokutsala abaphuhlisi abaninzi. Ngazo zonke ezi ziseko, inyaniso kukuba inkitha yeeprojekthi ezintsha nezinomdla ziyakhuthazwa kwaye zixhaswa. IMozilla iyavuna imali eyoneleyo Ngenxa yempumelelo yabo ngemithombo yabo evulekileyo kunye neetekhnoloji zewebhu, kwaye enkosi kwimali eqokelelweyo, ngoku baya kuwonga loo mali incinci sithethe ngayo kumhlathi odlulileyo kwiiprojekthi zemithombo evulekile. Ngokukodwa ngamabhaso ukuya kuthi ga kwi-539.000 yeedola zaseMelika.
Abanye be iiprojekthi Sithetha, umzekelo, Ushahidi (iprojekthi yokwabelana kunye nokwenza ingqokelela yolwazi lwasekhaya), RiseUp (uphuhliso lwezixhobo zokhuseleko lwedijithali kubaphembeleli), Phaser (injini yemizobo yemidlalo yevidiyo esekwe kwi-HTML5), njl.
