If you want to go that route, backup your Firefox bookmarks and such first and uninstall Firefox before you attempt to install Firefox ESR. As such, on Linux Mint 17.3 Firefox ESR is not available other than by manually downloading and installing it (each time a new version is released) from the Mozilla website. Note that there are good reasons not to want to use Firefox ESR. Or accept that the developer of the extension abandoned it long ago, nobody else is interested in maintaining it, so you'll just have to do without that on Firefox.įor a while longer you can use Firefox ESR which is based on Firefox 38 or 45.

If you don't like where Firefox is heading because you're using some unmaintained and long ago abandoned extension (and thus nobody has adapted it in past year to work with the new addon architecture), that you can't do without and for which there are no alternatives, then you should probably start looking for another web browser to use. Especially not for the most vulnerable piece of software on your computer-the one connecting to the Internet.

Using an outdated version of software, with known security issues that are fixed in newer versions, is not a good idea. Within /var/cache/apt/archives/ I found a couple of firefox deb filesįirefox-locale-en_46.0+linuxmint+rosa_amd.debĪny way of accessing similar package files for say Firefox 44? How much are the Mint repository versions customized from the Linux versions available on the Firefox website? What about differences between the Debian and Ubuntu versions? I understand there will be dependency differences, but will these render Firefox buggy or inoperable or potentially trash my Mint install? I am currently using the latest Mint repository version, v46, and used the command sudo apt-mark hold firefox to stop its package being upgraded further by the Update Manager. With all the changes happening with Firefox with respects to addon architecture and Modzilla's move towards WebExtensions in Firefox 48, is there a way to install, or revert, to an older version of Firefox?

I am a long time Windows user and only started playing with Linux Mint 17.3 a couple of weeks ago, so still very green when it comes to navigating my way around Linux.
