Publicado<\/a><\/noindex> atualiza\u00e7\u00e3o corretiva do Firefox 69.0.3 que resolve problema<\/a><\/noindex> o problema de exibi\u00e7\u00e3o do di\u00e1logo para download de arquivos ao clicar em e-mail no webmail do Yahoo. Al\u00e9m disso, foram resolvidos problemas<\/a><\/noindex> os problemas de download de arquivos ao iniciar o navegador no Windows 10 com o controle dos pais ativado.<\/p>\n

Tamb\u00e9m pode ser destacado o desenvolvimento cont\u00ednuo<\/a><\/noindex> do sistema de composi\u00e7\u00e3o WebRender<\/a><\/noindex>, desenvolvido na linguagem Rust e que transfere para o 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 motor Gecko, que processa dados com a CPU, para realizar as opera\u00e7\u00f5es de renderiza\u00e7\u00e3o de elementos da p\u00e1gina s\u00e3o utilizados shaders, executados no GPU, o que permite um aumento significativo na velocidade de renderiza\u00e7\u00e3o e reduz a carga na CPU. <\/p>\n

O WebRender foi adicionado ao vers\u00f5es noturnas<\/a><\/noindex> navegador m\u00f3vel Firefox Preview<\/a><\/noindex> (substituto do Firefox para Android) e ativado por padr\u00e3o para dispositivos Pixel 2 (para outros dispositivos, \u00e9 necess\u00e1rio ativar gfx.webrender.all em about:config). O WebRender tamb\u00e9m aprimorou os sistemas de cache e renderiza\u00e7\u00e3o de imagens. O c\u00f3digo para rasteriza\u00e7\u00e3o de texto foi reformulado, permitindo alcan\u00e7ar<\/a><\/noindex> suporte ao posicionamento subpixel de texto em plataformas Linux e Android.<\/p>\n

Ao executar o Firefox sobre Wayland, um novo backend<\/a><\/noindex>, utilizando o mecanismo DMABUF<\/a><\/noindex> para renderizar em texturas e organizar<\/a><\/noindex> o compartilhamento entre diferentes processos de buffers contendo essas texturas, armazenadas na mem\u00f3ria de v\u00eddeo. Al\u00e9m disso, foram adicionadas otimiza\u00e7\u00f5es de desempenho na decodifica\u00e7\u00e3o de imagens, utilizando instru\u00e7\u00f5es SIMD para acelerar e reduzir o tempo de convers\u00e3o de formatos em 5-10%.<\/p>\n
