A Canonical come\u00e7ou a trabalhar na resolu\u00e7\u00e3o de problemas de desempenho do pacote snap do Firefox, que foi proposto como padr\u00e3o no Ubuntu 22.04 em vez do tradicional pacote deb. A principal insatisfa\u00e7\u00e3o dos usu\u00e1rios est\u00e1 relacionada ao lan\u00e7amento muito lento do Firefox. Por exemplo, em um laptop Dell XPS 13, a primeira inicializa\u00e7\u00e3o do Firefox ap\u00f3s a instala\u00e7\u00e3o leva 7,6 segundos, em um Thinkpad X240 leva 15 segundos, e em uma placa Raspberry Pi 400 leva 38 segundos. As reinicializa\u00e7\u00f5es j\u00e1 ocorrem em 0,86, 1,39 e 8,11 segundos, respectivamente. <\/p>\n
Durante a an\u00e1lise do problema, foram identificadas 4 causas principais para a inicializa\u00e7\u00e3o lenta, que ser\u00e3o o foco da solu\u00e7\u00e3o: <\/p>\n
Ao iniciar o Firefox a partir do snap, tamb\u00e9m foram observados problemas de desempenho durante a opera\u00e7\u00e3o, mas os desenvolvedores do Ubuntu j\u00e1 prepararam corre\u00e7\u00f5es que melhoram a performance. Por exemplo, a partir do Firefox 100.0, otimiza\u00e7\u00f5es foram inclu\u00eddas na fase de linkagem (LTO) e com base nos resultados da profilagem de c\u00f3digo (PGO). Para resolver problemas de comunica\u00e7\u00e3o entre o Firefox e subsistemas externos, um novo XDG Desktop Portal foi preparado, cuja implementa\u00e7\u00e3o est\u00e1 sendo revisada para inclus\u00e3o no Firefox. <\/p>\n
Entre as raz\u00f5es para a promo\u00e7\u00e3o do formato snap para navegadores est\u00e1 o desejo de simplificar a manuten\u00e7\u00e3o e unificar o desenvolvimento para diferentes vers\u00f5es do Ubuntu \u2014 o pacote deb requer manuten\u00e7\u00e3o separada para todos os ramos suportados do Ubuntu e, consequentemente, compila\u00e7\u00f5es e testes considerando diferentes vers\u00f5es de componentes do sistema, enquanto o pacote snap pode ser formado de uma vez para todos os ramos do Ubuntu. Al\u00e9m disso, o pacote snap do Firefox oferecido no Ubuntu \u00e9 mantido por funcion\u00e1rios da Mozilla, ou seja, ele \u00e9 criado diretamente, sem intermedi\u00e1rios. A entrega no formato snap tamb\u00e9m permitiu acelerar a disponibiliza\u00e7\u00e3o de novas vers\u00f5es do navegador para os usu\u00e1rios do Ubuntu e possibilitou a execu\u00e7\u00e3o do Firefox em um ambiente isolado, criado com o mecanismo AppArmor, para prote\u00e7\u00e3o adicional do sistema contra a explora\u00e7\u00e3o de vulnerabilidades no navegador.
