I have a smaller SSD drive for my OS and would like to install Firefox on my larger HDD but don't see any options to choose which drive it installs on. Thanks

It is easy to install Firefox on the D drive by doing a custom install.

However Firefox will create the profile folder that store your personal data on the Windows system partition and that is likely the C drive.

Make sure that you do not launch Firefox once the custom installation has finished because you need to use the Profile Manager to create profile folder on the D drive as well.

First you need to create a folder on the D drive that is exclusively used as the profile folder. This should be a new folder that doesn't have any files in it. Then you can start the Profile Manager and click the "Choose Folder" button on the second page to browse to the folder on the D drive you just created. Firefox will store all files in this specific folder.

Give it a descriptive name, click on the Choose Folder button, and then select the profile folder you moved or renamed, before you finish the Create a new profile wizard.
