Updating firefox in linux
I just unpack the new tarball into the version directory and have it "write into" and "overwrite" all. Just download the latest firefox x86_64 from mozilla site, unpack it in some dir in your home and make a soft link to ~/bin/firefox (add $HOME/bin to your $PATH).
Then, download the latest flash plugin from adobe site, untar it in /tmp (because it's packed to be untared on / so it spreads all its crap all over the sys) and copy only the to ~/.mozilla/plugins.
Please share your experience with Open Suse and Fedora in the comments.

This how-to explains how to install Firefox 55 on Linux, with or without replacing an existing Firefox installation. Warning for unexperienced Linux users: stick to the Firefox version included with your Linux distribution!

Here are a few examples of how many days Ubuntu and Linux Mint need to push the update: This howto has been tested with success on the following distributions, with Firefox 4 to 55 and Firefox Beta: Cent OS / Scientific Linux / RHEL 6.9 & 7.3 Debian 7 “Wheezy” Debian 8.x “Jessie” Linux Mint 17 “Qiana” LTS (support until April 2019) Linux Mint 17.1 “Rebecca” LTS (support until April 2019) Linux Mint 17.2 “Rafaela” LTS (support until April 2019) Linux Mint 17.3 “Rosa” LTS (support until April 2019) Linux Mint 18 “Sarah” LTS (support until April 2021) Linux Mint 18.1 “Serena” LTS (support until 2021) Linux Mint 18.2 “Sonya” (beta release) Ubuntu 14.04 LTS “Trusty Tahr” (Long Term Support, until April 2019) Ubuntu 16.04 LTS “Xenial Xerus” (support until April 2021) Ubuntu 16.10 “Yakkety Yak” (support until July 2017) Ubuntu 17.04 “Zesty Zapus” (support until January 2018) This installation procedure is reliable and should work with a wide range of distributions.- this is the equivalent of a Nightly build of Firefox.Although these packages will work well most of the time, you should expect crashes and other problems.These testing versions are not meant to be stable or usable.→ Avoid this ppa unless you know exactly what you’re doing!
