If you click the Firefox icon but no Firefox window opens and no error message is shown, a simple first step is to restart your computer and then try again. If Firefox still does not start, maybe something here will help: Firefox won't start - find solutions (under No error message) Troubleshoot and diagnose Firefox problems (try numbered steps and also Other solutions)

You mentioned Firefox will not start up in Administrator mode. That can actually cause the problem, according to https://support.mozilla.org/en-US/questions/1280478#answer-1292602 How to get Firefox to start.
rebooted- didnt use Admin mode created new profile tried to "run" with new profile nothing seems to work still cant get even run command firefox.exe-p to run anything else ? thanks! Mike
Did you recently uninstall an application that was using Visual C+ runtime components?
You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.
See "Visual Studio 2015, 2017, 2019, and 2022":
You may also have to install the Visual Studio 2013 Redistributable Package. You need to reboot the computer.

I was wondering if that might be the problem. The Troubleshoot and diagnose Firefox problems article Other solutions section has a Check for issues caused by corrupt or incomplete Visual C++ installation paragraph I added a little while ago.

What security software are you running? Are you running Win 10 Pro? If so, do you have Windows Sandbox setup? You should have it setup for testing issue like this. https://www.howtogeek.com/399290/how-to-use-windows-10s-new-sandbox-to-safely-test-apps/ Can you watch task manager and see if the process even loads? Also, try downloading a different version (Beta, Dev, or Nightly) and install in a different directory to see what happens. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

how do i now "sync" to get all my extensions/apps/bookmarks from previous install?
or, does that tell you something about my current firefox that i can fix ? Thanks Mike
Did you ever disable all those tools, reboot, and see if your Firefox works?
and now i went into task manager and "ended" all those tools, and still no original firefox
do you all have a "firefox diagnositc" program that will show what my problem is ? Thanks Mike
No, you need to disable those tools, reboot, and try again.
ok-went into each program and disabled startup rebooted laptop still no firefox
i mean when i execute, it doesnt do anything mike
Did you ever use sync?
Since the new browser works, maybe cor-el can chime in on what files to move to the new browser.
yes i do that with my iphone ( or at least i see that on my iphone...
i actually have a "json" backup, but a year old, and i imported that into my "firefox2" - which works what i really wanted was all those "extensions"/"addons" that i had is there a way to restore those ?
if not, is there a way to "save/backup" all bookmarks/extensions/options/etc so if this happens again
wow, i just digned into "sync" and all my extensions/addons came back into my firefox2 i guess "problem solved" and i will use my firefox 2 from now on thansk mike
This is why it's a good idea to run more than 1 version of Firefox, so that your data is not just in 1 place. see screenshot Since your data is now in Firefox 2, you can try to reinstall Firefox 1 and see if it helps. You can also just mark this issue resolved if your done. ;-)
Just checking in to see how's it going since this issue is still open?
