The error page for sites with invalid TLS certificates was missing the
activation-delay Firefox uses to protect prompts and permission dialogs
from attacks that exploit human response time delays. If a malicious
page elicited user clicks in precise locations immediately before
navigating to a site with a certificate error and made the renderer
extremely busy at the same time, it could create a gap between when
the error page was loaded and when the display actually refreshed.
With the right timing the elicited clicks could land in that gap and
activate the button that overrides the certificate error for that site. This vulnerability affects Firefox ESR < 102.12, Firefox < 114, and Thunderbird < 102.12.

Beyond the WebP Flaw | An In-depth Look at 2023's Browser Security Challenges
This week, Firefox users were urged to apply Mozilla’s latest updates against a critical flaw that could allow attackers to take control of affected systems. It follows hard on the heels of similar updates for Microsoft Edge, Google Chrome, and Apple’s Safari browser. All have been heavily impacted by an actively exploited vulnerability in the WebP code library.
Although the WebP vulnerability affects other software as well, browsers are by far and away the most ubiquitous and widely used applications on end user devices . Having a foothold in a compromised browser gives threat actors access to sensitive information and potential avenues into targeted environments.

As well as the TLS certificate exception screen pointed out by CVE-2023-34414, HTTPS-Only mode disable button does not have activation-delay implemented. This could be used for clickjacking with human response time delays.
In the following example site, when the mouse touches the button labeled Click Me, the screen switches to the HTTPS-Only Mode warning page. If the user presses the button even a little late, the button to disable HTTPS-Only Mode is inadvertently pressed, and the page transition to the http: page is succeeded.
