Firefox Portable ver 115.117.0

[Niloc24]

I'm trying to update/replace Firefox Portable ver 96 on my Win7 64 bit PC with ver 115.117.0. I tried 'copying' the new ver over the old ver 96, but it simply created a sub folder within 96. I then tried to 'copy' 115 to a new folder & import my saved ver 96 profile folder. That didn't work either !

On my 64 bit PC, I like to run Firefox Portable in 32 bit mode, but with ver 115 that seems impossible, as there is no 32 bit 'App/Firefox' folder, only the 64 bit one. 

But because I also want to setup ver 115 on an old 32 bit Win7 laptop, after 'copying' there was no 32 bit 'App/Firefox' folder, only the 64 bit one - as wtih my PC, above.

How can I get FF 115 ESR to work in 32 bit on my PC & on this old laptop?

Help would be very much appreciated - many thanks, Niloc

x32 arch is being dropped by most hardware developers, so there is a good chance that backwards compatibility is being forgotten about at this point. Search "*.exe" [or other executable file "*.elf" "*.mz" etc.] in your folder to see if there is another executable.

Thanks WindedDrip414 for your thoughts. I've not fixed the problem with Win7. BUT I now have a weird problem with FF ver 115.117.0 on my Win10 laptop. FF just won't save any changes or additions to my bookmarks !
Yet it works fine under Win7. I've gone into the About:Config browser settings, such as:-
setting 'browser.bookmarks.autoExport***' to True
and  settings 'browser.bookmarks.file' to be saved in the FF root folder

But in spite of the above, even after changes/additions to my bookmarks, there is no updated JSON file in the Profile\Bookmarks folder.

Can y ou or anyone please help fix this? Many thanks if you can, Niloc24
