From distrowatch.com:
"Years ago the Debian project renamed their Firefox package to Iceweasel.
This change in brand was brought about due to a complex situation where
Debian was patching the Firefox software and therefore running into conflict
with Mozilla's trademark agreement. In short, Debian's copy of Firefox was
different from Mozilla's version of Firefox and therefore Debian could no
longer call their web browser Firefox. The Debian project named their patched
version of Mozilla's web browser Iceweasel. Times change and it looks as
though there may no longer be a conflict between Mozilla and the Debian
project, meaning Debian may be able to call their copy of the Mozilla browser
Firefox again. Sylvestre Ledru has suggested Debian resume using the name
Firefox in order to avoid confusion and reduce the effort to maintain the web
browser package. "Mozilla & Debian both acknowledge that the branding issue
mentioned in bug 354622 is no longer relevant. The Firefox logo was released
under a free copyright license which matches the DFSG. To simplify the
maintenance of the current stable Debian release, the name Iceweasel will
remain. Debian Stretch, the next release, will have Firefox as package name."
