The jessie-backports repository does not have the latest Iceweasel builds. However, the Debian Mozilla team releases its own backports. To use their backports follow the steps below:
# apt-get install pkg-mozilla-archive-keyring
# echo "deb http://mozilla.debian.net/ jessie-backports iceweasel-release" >> /etc/apt/sources.list
# apt-get install -t jessie-backports iceweasel
At the time of writing this post, the Mozilla team’s repository provides Iceweasel 42, compared with 38.4 with the regular Jessie repository.
I got an error message when I try to open Iceweasel on debian no root on android.
“Your firefox profile cannot be loaded. It may be missing or inaccessible.”
What should I do to fix that?
I have no experience with running Debian on android. Guess you can try deleting your Firefox profile and creating a new one by running
firefox -P.
