Lançado o Firefox 102

Novidades
Cansado de muitas janelas lotando sua tela? Agora você pode desativar a abertura automática do painel de download toda vez que um novo download for iniciado.
O Firefox agora reduz o rastreamento de parâmetros de consulta ao navegar em sites no modo estrito ETP.
Legendas para Picture-in-Picture (PiP) já estão disponíveis na
- HBO Max
- Funimation
- Dailymotion
- Tubi
- Disney+ Hotstar
- SonyLIV
Isso permite que você visualize o vídeo em uma pequena janela fixada em um canto da tela enquanto navega entre aplicativos ou navega pelo conteúdo na tela principal.
Correções
Ao usar um leitor de tela no Windows, pressionar Enter para ativar um elemento não falha mais ou clica no elemento errado e/ou em outra janela do aplicativo. Para cegos ou com visão muito limitada, essa tecnologia lê em voz alta o que está na tela, e os usuários podem adaptá-los às suas necessidades (agora, em nossa plataforma, sem erros).
Várias correções de segurança.

#CVE-2022-34482: Drag and drop of malicious image could have led to malicious executable and potential code execution
Reporter
Attila Suszter
Impact
moderate
Description
An attacker who could have convinced a user to drag and drop an image to a filesystem could have manipulated the resulting filename to contain an executable extension, and by extension potentially tricked the user into executing malicious code. While very similar, this is a separate issue from CVE-2022-34483.

Reporter
Peter Gerber
Impact
moderate
Description
When a TLS Certificate error occurs on a domain protected by the HSTS header, the browser should not allow the user to bypass the certificate error. On Firefox for Android, the user was presented with the option to bypass the error; this could only have been done by the user explicitly.
This bug only affects Firefox for Android. Other operating systems are unaffected.

#CVE-2022-34478: Microsoft protocols can be attacked if a user accepts a prompt
Reporter
Gijs
Impact
moderate
Description
The ms-msdt, search, and search-ms protocols deliver content to Microsoft applications, bypassing the browser, when a user accepts a prompt. These applications have had known vulnerabilities, exploited in the wild (although we know of none exploited through Firefox), so in this release Firefox has blocked these protocols from prompting the user to open them.
This bug only affects Firefox on Windows. Other operating systems are unaffected.

#CVE-2022-34484: Memory safety bugs fixed in Firefox 102 and Firefox ESR 91.11
Reporter
Mozilla developers and community
Impact
high
Description
The Mozilla Fuzzing Team reported potential vulnerabilities present in Firefox 101 and Firefox ESR 91.10. Some of these bugs showed evidence of JavaScript prototype or memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
