O Anúncio do lançamento foi feito em 10 de março de 2020.

Melhorias
- Seu gerenciamento de login foi aprimorado com a capacidade de reverter a classificação alfa (Nome Z-A) no Lockwise, que você pode acessar em Logins e Senhas.
- Agora, o Firefox simplifica a importação de seus favoritos e histórico do novo navegador Microsoft Edge no Windows e Mac.
- Os complementos instalados por aplicativos externos agora podem ser removidos usando o Gerenciador de Complementos (sobre: addons). No futuro, apenas usuários poderão instalar complementos; eles não podem ser instalados por um aplicativo.
- O Contêiner do Facebook impede que o Facebook o rastreie pela Web - logins, curtidas e comentários do Facebook são bloqueados automaticamente em sites que não são do Facebook. Mas quando precisamos de uma exceção, agora você pode criar uma adicionando sites personalizados ao contêiner do Facebook.
- O Firefox agora oferece melhor privacidade para suas chamadas de voz e vídeo na Web por meio do suporte ao mDNS ICE, ocultando o endereço IP do seu computador com um ID aleatório em determinados cenários do WebRTC.

#CVE-2020-6808: URL Spoofing via javascript: URL
Reporter
Abdulrahman Alqabandi
Impact
moderate
Description
When a JavaScript URL (javascript:) is evaluated and the result is a string, this string is parsed to create an HTML document, which is then presented. Previously, this document's URL (as reported by the document.location property, for example) was the originating javascript: URL which could lead to spoofing attacks; it is now correctly the URL of the originating document.

#CVE-2020-6810: Focusing a popup while in fullscreen could have obscured the fullscreen notification
Reporter
Avi Drissman of the Chrome security team
Impact
moderate
Description
After a website had entered fullscreen mode, it could have used a previously opened popup to obscure the notification that indicates the browser is in fullscreen mode. Combined with spoofing the browser chrome, this could have led to confusing the user about the current origin of the page and credential theft or other attacks.

#CVE-2020-6811: Devtools' 'Copy as cURL' feature did not fully escape website-controlled data, potentially leading to command injection
Reporter
Ophir LOJKINE
Impact
moderate
Description
The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP method of a request, which can be controlled by the website. If a user used the 'Copy as Curl' feature and pasted the command into a terminal, it could have resulted in command injection and arbitrary command execution.

#CVE-2019-20503: Out of bounds reads in sctp_load_addresses_from_init
Reporter
Natalie Silvanovich of Google Project Zero
Impact
moderate
Description
The inputs to sctp_load_addresses_from_init are verified by sctp_arethere_unrecognized_parameters; however, the two functions handled parameter bounds differently, resulting in out of bounds reads when parameters are partially outside a chunk.

#CVE-2020-6812: The names of AirPods with personally identifiable information were exposed to websites with camera or microphone permission
Reporter
Jan-Ivar Bruaroey
Impact
moderate
Description
The first time AirPods are connected to an iPhone, they become named after the user's name by default (e.g. Jane Doe's AirPods.) Websites with camera or microphone permission are able to enumerate device names, disclosing the user's name. To resolve this issue, Firefox added a special case that renames devices containing the substring 'AirPods' to simply 'AirPods'.

Reporter

Impact
high
Description
Mozilla developers Byron Campen, Jason Kratzer, and Christian Holler reported memory safety bugs present in Firefox 73 and Firefox ESR 68.5. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
