Please add an easy single button way to disable the JavaScript Just-In-Time Compilation (JIT) like in Chrome or Edge. I like to have this disabled for security reasons to reduce the amount of possible exploits because this is one of the most common ways to exploit your browser. In Chrome or Edge is it relatively easy to do this, however in Firefox, you must change a bunch of stuff in the config menu. Which may put off some users in disabling this commonly exploited feature.

The video mentioned that those config options are unofficial and may be overkill. Are there an official set of options to disable JIT within Firefox? I'm also curious if there is any way to do this on Firefox android.

@Flop4424 There currently is no way to disable JIT in Firefox android. And the config options are currently the only way to disable it on desktop. That's why I'm hoping they'll add this as a main setting like Chrome and Edge.
