Em noturnos<\/a><\/noindex> compila\u00e7\u00f5es do Firefox, a partir das quais \u00e9 formado o lan\u00e7amento do Firefox 70, inclu\u00eddo<\/a><\/noindex> por padr\u00e3o a aplica\u00e7\u00e3o do sistema de composi\u00e7\u00e3o WebRender<\/a><\/noindex> para placas de v\u00eddeo NVIDIA em sistemas Linux com o driver Nouveau e pacote Mesa 18.2 ou vers\u00e3o mais nova. Configura\u00e7\u00f5es com drivers propriet\u00e1rios NVIDIA ainda erros cr\u00edticos que bloqueiam o lan\u00e7amento (h\u00e1 10 dias eram 146, um m\u00eas e meio atr\u00e1s eram 316, dois meses atr\u00e1s eram 577, no momento da congelamento no Debian 9 eram 275, no Debian 8 eram 350, no Debian 7 eram 650). O lan\u00e7amento final do Debian 10 \u00e9 esperado para o ver\u00e3o.<\/a><\/noindex> sem suporte ao WebRender. O WebRender para GPUs AMD e Intel, ao usar Mesa 18+ nas compila\u00e7\u00f5es di\u00e1rias, j\u00e1 foi ativado anteriormente. Tamb\u00e9m \u00e9 observado a retomada<\/a><\/noindex> do suporte ao WebGL nas compila\u00e7\u00f5es di\u00e1rias do Firefox em sistemas com drivers Nouveau, que foi acidentalmente desativado no Firefox 68 (atualmente a limita\u00e7\u00e3o foi transferido<\/a><\/noindex> \u00e9 apenas para o driver propriet\u00e1rio NVIDIA).<\/p>\n

Lembramos que o sistema de composi\u00e7\u00e3o WebRender<\/a><\/noindex> \u00e9 escrito na linguagem Rust e delega ao GPU as opera\u00e7\u00f5es de renderiza\u00e7\u00e3o do conte\u00fado da p\u00e1gina. Ao usar o WebRender em vez do sistema de composi\u00e7\u00e3o embutido no mecanismo Gecko, que processa dados com a CPU, s\u00e3o utilizados shaders executados no GPU para realizar opera\u00e7\u00f5es de renderiza\u00e7\u00e3o conjunta dos elementos da p\u00e1gina, o que resulta em um aumento significativo da velocidade de renderiza\u00e7\u00e3o e reduz a carga na CPU. <\/p>\n

Nos lan\u00e7amentos est\u00e1veis, o WebRender est\u00e1 atualmente ativado apenas para a plataforma Windows 10 com placas de v\u00eddeo AMD e NVIDIA. Para verificar a ativa\u00e7\u00e3o do WebRender, voc\u00ea pode acessar a p\u00e1gina about:support. Para for\u00e7ar a ativa\u00e7\u00e3o no about:config, \u00e9 necess\u00e1rio ativar as configura\u00e7\u00f5es \"gfx.webrender.all\" e \"gfx.webrender.enabled\" ou iniciar o Firefox com a vari\u00e1vel de ambiente MOZ_WEBRENDER=1.<\/p>\n

Adicionalmente, pode-se destacar in\u00edcio<\/a><\/noindex> Testes no Firefox 69 Beta e na Developer Edition (atualmente apenas nas vers\u00f5es para Windows) da funcionalidade de visualiza\u00e7\u00e3o de v\u00eddeo no modo \"imagem em imagem\" (Picture-in-Picture), que permite destacar o v\u00eddeo em uma janela flutuante que permanece vis\u00edvel enquanto voc\u00ea navega no navegador. Para visualizar nesse modo, voc\u00ea deve clicar na dica de ferramenta pop-up ou no menu de contexto exibido ao clicar com o bot\u00e3o direito do mouse no v\u00eddeo e selecionar \"Picture in picture\" (no YouTube, que substitui seu pr\u00f3prio manipulador de menu de contexto, voc\u00ea deve clicar duas vezes com o bot\u00e3o direito do mouse ou clicar enquanto mant\u00e9m a tecla Shift pressionada).<\/p>\n
