How can I transfer my cookies from a Mac to a Windows?

GMLW

I'm planning on getting a Windows computer. However, I don't want to lose all the cookies in my Mac. Firefox sync doesn't sync cookies, and a Google search has only told me how to transfer them from Windows to Mac, not the other way around. Can anybody help me out?

Hello GMLW, follow madperson's reply and will not find any problem, all firefox files (places.sqlite , cookies.sqlite etc) is the same in all Os.

thank you

hello GMLW, please have a look at the following article: Restore bookmarks, passwords and data from an old Firefox profile

It says I have to copy files into a new location, which I'm aware of. My main worry is whether or not all the files I want to transfer will be Windows compatible as well. Will there be any problems due to filename extensions or whatnot when crossing between OS's?

Note that not all cookies may be working if the user agent changes significantly as happens with a platform change.

The permissions.sqlite file stores the exceptions, including cookie exceptions, that you have created.

Okay, thank you.
