My version of Firefox is 108.0.1 -- I am running Windows 10 on a machine that Windows says is not capable of running Windows 11

My installation of Firefox resides on my D: drive. It uses quite a bit of space for cache and other things on my C: drive but it starts and runs on my D: drive.Now I am forced to update, but I can't get the installer to recognize an installation on the D: drive and update it. Instead it makes a new installation on my C: drive and I lose my appearance customizations, history and bookmarks.

I have never believed and cannot accept that an application absolutely MUST reside on the C: drive. It's lazy programming (something I used to do for a living). I can't believe Mozilla programmers wrote an installer that insists that Firefox must live there, so what am I missing? How do I tell the installer to find and update my existing application?

Thanks for your help. I feel as if I am missing something that ought to be obvious.

Any software regardless of Firefox will always default install on C:\ drive and if you changed that from default the user must pick the option to get the software during updates or reinstall to install to the custom drive otherwise it will go to C:\ by default. If there is a error you need to post that installation error so others can verify and replicate the issue on the installation. Otherwise you need a bigger C:\ drive to only store installation as it sounds like your using C: for file storage and running software to which you should get a second drive to keep your data on separate from C: drive.

Sounds like you may be trying to install Firefox with the small online stub installer instead of the full offline setup as you can get it from https://www.mozilla.org/firefox/all/desktop-release/win64/
