Hello to every single one of you guys! I had been using Windows 7 for 8 years before switched to Linux Mint. Discovered Elive a couple of days ago, just installed the latest stable version. Could you guys tell me if it's possible to download a newer version of Firefox? Maybe there's another updated browser that I could install?
That would be about the same question as here:
https://forum.elivelinux.org/t/modern-browser-on-3-0-6
Tl;dr you can't get the latest version of almost all browsers because 32-bit and old.
However you can get a recent version of Palemoon. https://forum.elivelinux.org/t/install-latest-palemoon-on-elive-3-0-6-stable/2253
The link in that post is invalid due to palemoon not being made for 32bit anymore. 
I'm going to remove it as it's not relevant anymore.
It's still a recent release and better than the FF version.
There are only current 64bit versions there now.
No old ones.
Last versions in 32bit from: Index of /palemoon/28.x/28.9.3/
The Elive repository includes a .deb in 32 bit version too (29.4.1)
