Novidades

• Agora é possível importar favoritos, histórico e senhas não apenas do Edge, Chrome ou Safari, mas também do Opera, Opera GX e Vivaldi para todas as pessoas que desejam migrar para o Firefox!
• A sandbox de GPU foi habilitada no Windows.
• Observação: um bug na popular ferramenta X-Mouse Button Control (XMBC) pode fazer com que a rolagem da roda do mouse pare de funcionar. Os autores estão trabalhando em uma atualização. Enquanto isso, a rolagem pode ser restaurada reconfigurando o XMBC: desative a opção Tornar a janela de rolagem da roda de rolagem sob o cursor nas configurações globais ou ative a opção Desativar a janela de rolagem sob o cursor se estiver usando um perfil personalizado para o Firefox.
• No Windows, os módulos de terceiros agora podem ser impedidos de se injetar no Firefox, o que pode ser útil se estiverem causando falhas ou outro comportamento indesejável.
• Os campos de entrada de data, hora e local de data e hora agora podem ser limpos com o atalho Cmd+Backspace e Cmd+Delete no macOS e Ctrl+Backspace e Ctrl+Delete no Windows e Linux.
• O Canvas2D acelerado por GPU é ativado por padrão no macOS e Linux.
• Melhoria de desempenho do WebGL no Windows, MacOS e Linux.
• Permite a sobreposição de vídeo decodificado por hardware com GPUs não Intel no Windows 10/11, melhorando o desempenho de reprodução de vídeo e a qualidade de dimensionamento de vídeo.
