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.
