How can I retrieve the current profile path & name from a command line?

I'm trying to create a DOS batch file to clear the current profile's cache (web site data only, not cookies). I have it working fine using a hard-coded path of the existing profile (I only have one profile), but I'd like it to remain viable in case a newer profile is created for whatever reason. Is there a way to retrieve the path into a variable?

Thank you!

I don't think there is such an option: https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options

We do not recommend using other programs to clean Firefox because they could corrupt the files. Also, the browser can clean itself.


Type about:preferences#privacy<enter> in the address box. The button next to History, select Use Custom Settings.

Turn off Always Use Private Browsing Mode Turn on Remember My Browsing And Download History At the bottom of the page, turn on Clear History When Firefox Closes. At the far right, press the Settings button. Turn on ONLY Cache and Form And Search History leaving the others off.

Once upon a time I wrote a VBScript to parse the installs.ini file for default profile paths and build a session history file backup script. I'm not sure it works in 2022, but if you want to take a look for inspiration:

Thank you for this - I wasn't pursuing a solution within FF because I only knew of the option to clear BOTH cache and cookies when FF exits. This looks like a great way to do what I want. (I will say, it seems to me that the option in Settings should allow selection of cookies separately from cache, just like it does in the nearby "Clear Data" function.)

I appreciate the help!

This is the way. And now I understand what I was missing all along. Thank you!
