Dear John,

I applied the update on 2 computers of mine (both Win 10) and I notice the same bug : the Firefox window size (maximized in my case) is not restored on launch. I've never had this problem with past versions. Do you know what could happen ?

Thanks a lot and have a great day !

Both local and portable Firefox launch maximized if they were maximized on close. If you'd like more detailed assistance, please post a note in the Firefox Portable support forum and include your full OS version (including build and bit depth), full path, and any extensions you are using as they can affect it.

Sometimes, the impossible can become possible, if you're awesome!
