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.
