Files that can be safely deleted from a Firefox profile?

Hello Portable Apps family, Can you help me understand which files and folders can be safely deleted from a Firefox Portable profile manually from the "Data\profile" folder. Let's say that I created a Firefox Portable profile in a folder named "FirefoxPortable" and made all necessary changes I like and placed it in drive "D:"
After a few hours of browsing session I want to manually delete ANY FILES AND FOLDERS ( from profile's "Data\profile" folder) that are not necessary for it to function without losing any changes I did and extensions and bookmarks I added before I placed it in D. Thanks a million.

Post Your Questions to mozillaZine

Your questions really relate to Firefox in general, not necessarily to PortableApps implementation of Firefox. You would best to ask your questions at

If you do post there do mention that you are using portable Firefox, though I think that as your questions relate to your Firefox profile then that shouldn't really make much difference. The folks at mozillaZine are very knowledgable and should be able to steer you in the right direction.

Use Portable Apps on both Flash Drive and HDD/SSD.
