The rather old Firefox 18.0.1 was released back on January 18, 2013 and is vulnerable as it is behind on a long list of security fixes since, many of which were critical. https://www.mozilla.org/en-US/security/known-vulnerabilities/firefox/

You are Not more secure by using Firefox 18.0.1

Mozilla adds Plugins and Extensions to blocklist when they are serious security, malware and stability concerns. https://addons.mozilla.org/en-US/firefox/blocked/

Adobe has had two recent updates for their Flash player Plugins in fixing critical vulnerabilities. https://helpx.adobe.com/security.html

The current versions of Flash (plugin based for browsers like Firefox/SeaMonkey) are at https://www.adobe.com/products/flashplayer/distribution3.html

The flash fix is to use the current, not old versions.

Why is my version of Firefox more secure? it is farther away from the OS it does not interact with explorer and it has its own Java control.

What do you mean by "farther away from the OS"? In what ways do you believe that newer versions of Firefox "interact with explorer"? What do you mean by "its own Java control"?

I want the BROWSER to only BROWSE the internet not download things automatically, not shutdown my plugins without asking, not allow poorly coded scripts to execute code on my machine (including no-right click scripts). I need to know how to STOP my firefox from updating the addon manager. How to keep it from allowing IE only code from running as it has now started allowing no-right click scripts to execute.

What is Firefox downloading automatically that you do not want to download?

If you want to prevent scripts from overriding the normal right-click context menu, there is an about:config setting for that and also one or more extensions.*

Regarding updating: Firefox updates itself, Firefox updates your extensions, Firefox blocks malicious and vulnerable add-ons, this is part of its design to keep you as safe as possible on the web. There probably are ways to go into the plubing and wreck it so none of that works, but we certainly cannot recommend that. Using a version released 30 months ago, with a long list of publicly disclosed security vulnerabilities, is asking for the worst. If you cannot or will not run Firefox 39, please switch to a different, up-to-date browser.

* To always get Firefox's right-click menu, try this setting:

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the search box above the list, type or paste event and pause while the list is filtered

(3) Double-click the dom.event.contextmenu.enabled preference to switch its value from true to false

After making this change, if you encounter a problem on a site like Google maps where you want to access the site's right-click menu but Firefox's is blocking it, press and release the Alt key to clear Firefox's menu.

If some sites use other techniques to do annoying things when you right-click, consider this extension (I haven't needed it myself): https://addons.mozilla.org/firefox/addon/righttoclick/
