  script_tag(name:"insight", value:"CVE-2022-29914: Fullscreen notification bypass using popups
When reusing existing popups Firefox would have allowed them to cover the fullscreen notification UI, which could have enabled browser spoofing attacks.

CVE-2022-29909: Bypassing permission prompt in nested browsing contexts
Documents in deeply-nested cross-origin browsing contexts could have obtained permissions granted to the top-level origin, bypassing the existing prompt and wrongfully inheriting the top-level permissions.

CVE-2022-29916: Leaking browser history with CSS variables
Firefox behaved slightly differently for already known resources when loading CSS resources involving CSS variables. This could have been used to probe the browser history.

CVE-2022-29911: iframe Sandbox bypass
Firefox did not properly protect against top-level navigations for an iframe sandbox with a policy relaxed through a keyword like allow-top-navigation-by-user-activation.

CVE-2022-29912: Reader mode bypassed SameSite cookies
Requests initiated through reader mode did not properly omit cookies with a SameSite attribute.

CVE-2022-29915: Leaking cross-origin redirect through the Performance API
The Performance API did not properly hide the fact whether a request cross-origin resource has observed redirects.

CVE-2022-29917: Memory safety bugs fixed in Firefox 100 and Firefox ESR 91.9
Mozilla developers Andrew McCreight, Gabriele Svelto, Tom Ritter and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 99 and Firefox ESR 91.8. 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.

CVE-2022-29918: Memory safety bugs fixed in Firefox 100
Mozilla developers Gabriele Svelto, Randell Jesup and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 99. 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.");
