Can I run Release Candidate (19.02), Beta, Nightly, Aurora and ESR versions on the same computer?

I know I can run the Beta and Nightly together on the same computer because they are installed in different directories. What I do then is that I have a Profile for each version. What I do is I run FireFox.exe -ProfileManager when I start either the Beta and Nightly builds.

My Question is can I also install the Aurora, Release Candidate and ESR versions on the same computer like I do with the Beta and Nightly? If so, how do I go about installing them in different directories? I will create new profiles for each version. What I then do is, copy everything in my original Profile to the newly create profiles so I can keep all my plugin/addons, themes, bookmarks, etc. the same.

Next question, (I think I know the answer but I just want to make sure) now can I sync my bookmarks from each of the different profiles that I created?

Secondly, I now I can do the ABOUT:CONFIG in the address bar of Firefox, does anyone have any idea where I can read up on what each entry means? Also, are there any other secrets in Firefox, similar to the ABOUT:CONFIG trick? I know of one app where you can do ABOUT:ME, but that's all I know.

I know this has been asked billions of times, but I also have to ask. Is there any chance at all that Firefox, Thunderbird, and/or Seamonkey will be ever release for the iOS from Apple? I know that it's impossible, but maybe someone MIGHT have some positive thoughts on this?

Lastly, I know this is off topic, but I'll give it a shot. I'm using Outlook 2013, does anyone know if Outlook can handle Newsgroups? The reason why I ask is because I've just learned that there are a ton of newsgroups for Firefox, ThunderBird, and SeaMonkey. I would like to, somehow, get those Newsgroups in Outlook 2013. I already get allot of the feeds for other things, so that's not a problem.

I would appreciate it very much if anyone could help me with these issues. Thank You.

See this for more information about running multiple different versions of 'Firefox'. Firefox, Beta, Aurora, and Nightly all install as 'Firefox' internally.

You can consider to use Firefox Sync to sync all the profiles.

You can do a custom install of each version and install each version in its own program folder.
Safest is to modify the desktop shortcut and add -P "profile name" to the command line to start each version with its own profile.
Be careful with clicking a file in Windows Explorer to open the default browser, so make sure to select the correct profile in the profile manager and check the don't ask setting.

Short answer on what has worked for ages is to have them installed in separate folders and to have each build start with its own Profile (no sharing).

Thanks, I did create a different Profile for each version of Firefox. Then (after I backed up my original Profile), I just copied everything from my original Profile to each version of Firefox I was running. Each version of Firefox checked all the addons/extensions to make sure they were compatible with the version of Firefox I was starting. Thank You!
