Vulnerability	Summary	Fixed by
VCID-3kra-bb93-aaan Aliases: CVE-2021-23983	By causing a transition on a parent node by removing a CSS rule, an invalid property for a marker could have been applied, resulting in memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 87.	87.0-1 Affected by 0 other vulnerabilities.
VCID-62jv-mdru-aaaa Aliases: CVE-2021-23986	A malicious extension with the 'search' permission could have installed a new search engine whose favicon referenced a cross-origin URL. The response to this cross-origin request could have been read by the extension, allowing a same-origin policy bypass by the extension, which should not have cross-origin permissions. This cross-origin request was made without cookies, so the sensitive information disclosed by the violation was limited to local-network resources or resources that perform IP-based authentication. This vulnerability affects Firefox < 87.	87.0-1 Affected by 0 other vulnerabilities.
VCID-9kp8-dukp-aaap Aliases: CVE-2021-23982	Using techniques that built on the slipstream research, a malicious webpage could have scanned both an internal network's hosts as well as services running on the user's local machine utilizing WebRTC connections. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9.	87.0-1 Affected by 0 other vulnerabilities.
VCID-ax5f-3a8e-aaad Aliases: CVE-2021-23984	A malicious extension could have opened a popup window lacking an address bar. The title of the popup lacking an address bar should not be fully controllable, but in this situation was. This could have been used to spoof a website and attempt to trick the user into providing credentials. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9.	87.0-1 Affected by 0 other vulnerabilities.
VCID-qjaf-segr-aaak Aliases: CVE-2021-23987	Mozilla developers and community members reported memory safety bugs present in Firefox 86 and Firefox ESR 78.8. 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. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9.	87.0-1 Affected by 0 other vulnerabilities.
VCID-rbnm-pmqn-aaaf Aliases: CVE-2021-23985	If an attacker is able to alter specific about:config values (for example malware running on the user's computer), the Devtools remote debugging feature could have been enabled in a way that was unnoticable to the user. This would have allowed a remote attacker (able to make a direct network connection to the victim) to monitor the user's browsing activity and (plaintext) network traffic. This was addressed by providing a visual cue when Devtools has an open network socket. This vulnerability affects Firefox < 87.	87.0-1 Affected by 0 other vulnerabilities.
VCID-wypr-856t-aaah Aliases: CVE-2021-23981	A texture upload of a Pixel Buffer Object could have confused the WebGL code to skip binding the buffer used to unpack it, resulting in memory corruption and a potentially exploitable information leak or crash. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9.	87.0-1 Affected by 0 other vulnerabilities.
VCID-ympr-e8tq-aaak Aliases: CVE-2021-23988	Mozilla developers reported memory safety bugs present in Firefox 86. 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. This vulnerability affects Firefox < 87.	87.0-1 Affected by 0 other vulnerabilities.
