Two versions of firefox on computer - How do I get rid of one?

I just noticed that I have an old (63.0.3) and a new (66.0.3) version of Firefox on my computer. I have no idea when or how this happened. Seems to work fine at the moment.

One is Mozilla Firefox 63.0.3 (x64 en-US) (170 MB). One is Mozilla Firefox 66.0.3 (x64 en-US) (175 MB). So my guess is this happened a while ago.

Both show up when I look at Apps & Features. Both are listed in Revo uninstaller.

There are two identical Firefox icons.

If I open one and check the version number in the program, it does show a different number depending on which icon I clicked to open the program. So there are definitely two versions.

They are sharing information. They open the same pages in several tabs that I had open when I closed the the program the last time.

I want to get rid of one but don't want to lose my many settings, bookmarks, etc. I don't want to risk everything by just Uninstalling the old version, unless I can be sure that it is safe.

Everything on my HP-PC is up to date.

Any ideas? Thanks!

Success!

It was super simple but I'm glad I took all precautions. I copied the profile to a flash drive and then uninstalled FF 63.

FF 66 was still fully 100% intact, as you predicted.

I wouldn't have dared attempt this without guidance. It took hours to research this and less than a minute to do it.

THANK YOU again.

For 63 display, the last part is \firefox.exe,0

For 66 display, the last part is \firefox.exe,0

Sorry about that.

That could a failed update that went wrong. If there are files in that location then you can remove the Mozilla Firefox folder there as well or try to uninstall the 63 via the Windows Control Panel since they point to different folders to see if that works.

How do I do a goof-proof backup of Firefox 66 and all my data/information that's on it? I don't want to get myself in trouble.

THANK YOU for all your help!

In case you would accidentally uninstall Firefox 66 as well (what I do not expect based upon the location you reported) then you won't lose personal data and you would only have to reinstall Firefox 66.

You can find the full version of the current Firefox release (66.0.3) in all languages and all operating systems here. You can download and save the full Firefox installer in case you need to reinstall Firefox.
