My current browser version is this: Firefox Quantum 69.0.2 (64-bit)
I have it for 2 months.
But is slowing down like crazy my entire PC, freezes all the windows, freezes the mouse, all the applications im working beside the open browser are freeze.
I have Process Explorer open all the time to monitor my Ram and CPU consume from applications, and the Ram is at FULL capacity.
I want you to tell me if is a Firefox Quantum 69.0.2 but on 32-bit version? From download page i only see one single version and is for 64-bit as the one i have installed already.
Thank you so much for your help.

Pick the Firefox channel, 64-bit or 32-bit (only for Linux and Windows), and the Language.

I've installed the 32-bit version over my already installed 64-bit. Without uninstalling the 64-bit. Just a simple installation. The button from the install window said "Upgrade" and it installed over successfully. I checked inside my newly installed browser Help- About Firefox it's vesrion and it reads as 32-bit now.
I am telling this because i know i should have unninstalled 64FF ,restart PC, install 32FF. But i did it this way in the hope my settings and customizations not to be lost from an unknown NEW version of FF. I am also afraid some 64-bit settings not to be active this way and jump up my RAM... but that i will test it in time and if its the case, i'll install properly. I want you to reasure me if it's all ok and i should not worry about it. Thank you so much for your help.

In Firefox 69 and later the user agent no longer shows what Firefox version you use, so if the platform is 64-bit Windows then it is always Win64 in the user agent.
Previously this would be WOW64 for 32-bit Firefox on a 64-bit Windows platform.
You need to check "Help -> About Firefox" or about:support to see the real Firefox version.

Note that is might not be a good idea to install 32-bit Firefox in the location used for 64-bit applications if you really did this.
(64-bit Firefox) "C:\Program Files\Mozilla Firefox\"
(32-bit Firefox) "C:\Program Files (x86)\Mozilla Firefox\"

TO dickvl
Yes you are right, i remember it was the case as you say it, [(32-bit Firefox) "C:\Program Files (x86)\Mozilla Firefox\"]
I just looked and in my case i have C:\Program Files\Mozilla Firefox\ (that suggests it is a 64-bit instalation folder but when i run the Firefox.exe from inside this folder, it's the 32 bit version, from Help- About Firefox. So... maybe it is user friendly after all.
But i get your warning, it could have installed a second mozilla folder for the 32 bit version and i could have 2 vesrions installed...but it looks it is OK , it overrides the previeous installation succesfully. Alright..but my concerns are a bit more deep, some files are written from the other version i had before and this one on 32 bit will have to deal with them... i hope im mistaken. Its just a hunch because im a veteran user on FF.

Your user settings and bookmarks are stored in a profile folder which is not in program files or program files (x86). It is in %appdata% (and then lower down). So uninstalling and reinstalling preserves settings. More detail
32-bit Firefox may use less memory, but I doubt it will fix your problem. Most problems are fixed by trying Firefox safe mode, and if safe mode fixes it, removing some extensions. Or, fixed by making a new profile and rebuilding it with some but not all of the old profile.
Try your method (32-bit) first and see, but if you keep having problems consider: ... on_Windows ... _-_Firefox
alternate interpretation of info: ... ld-profile
