Apart from security fixes, this should bring a lot of enhancements.
However some add-ons that have not been updated to stay compatible with the new version will not work.
If that's a big issue for you, you can still use the previously shipped version that you will find here: http://slackware.uk/slint/x86_64/slint-14.2.1/previous/
In case you already upgraded you can get back the old version this way then blacklist mozilla-firefox in /etc/slat-get/slapt-getrc:
Code: Select all
wget http://slackware.uk/slint/x86_64/slint-14.2.1/previous/mozilla-firefox-52.9.0esr-x86_64-1slint.txz
su
upgradepkg mozilla-firefox-52.9.0esr-x86_64-1slint.txz
To get the new version, as usual, use slapt-get or gslapt.
A big "Thank You" to George Vlahavas from whom I reused the script allowing to auto-magically package and sign (this is now mandatory for all Firefox add-ons) the 40 language packs bundled in the Firefox package.
