Most of the Firefox User Interface (UI), including the address bar and the tab strip, are implemented using standard web technologies like HTML, CSS and JavaScript plus some additional custom components like XUL. One of the advantages of using web technologies for the front end is that it allows rendering the frontend using the browser engine on all desktop operating systems. However, just like many web applications are susceptible to some form of injection attack (OWASP Top Ten), Firefox’s use of web technologies for the frontend makes it no exception and hence it is vulnerable to injection attacks as well.

Rules

While we are not an official Mozilla community, we have adopted the Mozilla Community Participation Guidelines as far as it can be applied to a bin.

Rules

Always be civil and respectful
Don’t be toxic, hostile, or a troll, especially towards Mozilla employees. This includes gratuitous use of profanity.
Don’t be a bigot
No form of bigotry will be tolerated.
Don’t post security compromising suggestions
If you do, include an obvious and clear warning.
Don’t post conspiracy theories
Especially ones about nefarious intentions or funding. If you’re concerned: Ask. Please don’t fuel conspiracy thinking here. Don’t try to spread FUD, especially against reliable privacy-enhancing software. Extraordinary claims require extraordinary evidence. Show credible sources.
Don’t accuse others of shilling
Send honest concerns to the moderators and/or admins, and we will investigate.
Do not remove your help posts after they receive replies
Half the point of asking questions in a public sub is so that everyone can benefit from the answers—which is impossible if you go deleting everything behind yourself once you’ve gotten yours.
