ftp.mozilla.org/pub/firefox/releases/
Folder: linux-x86_64
File: *.tar.bz2
Size: ~ 51MB
firefox(in firefox 56.x.x.) to firefox56, same with name of folder.
firefox(in firefox last ver) to firefoxlast, same with name of folder.
Eg. /../firefox56/firefox56
..../../firefox56/firefox56.png
with *.png for Icon(copy from /firefox/browser/icons/mozilla128.png)
4. Create a Desktop shortcut FF56
- Must FF in your system(we need shortcut)
- Install/reinstall: $sudo apt install firefox
- Copy and Mod Short cut(/usr/share/applications): Firefox Web Browser
- File: firefox.desktop.Rename to Firefox 56.desktop. Open it with Text Editor.
Mod: Find and Replace line(3lines):
"Exec=firefox" = "Exec=/[link]/firefox56"

"Icon=firefox"="Icon=/[Link]/firefox.png"
4.1 Delete update, updater.ini, update-settings.ini in firefox56.

5. (If you want)Uninstall FF in your system(FF 57)
6. Create a Desktop shortcut FF Last
Copy Firefox 56.desktop to Firefox Last.Desktop
Same with Step 4, but "firefox56" = "firefoxlast", ".png".
of just FInd and Replace(all): "firefox56" to "firefoxlast"
7. Create 2 Profile for FF56 and Last.
Run firefoxlast(just click to run). OK. it running.
Now im uninstall firefox(in my system).
$sudo apt remove firefox
Create profile with lastfirefox.
$/[link]/lastfirefox -P
+ Create Profile: Name "ff56" in Enter new profile name.
now: 2 profile(default for last and ff56 for version 56).
+Open file Firefox 56.desktop.
+ Find and replace(all,2): "firefox56/firefox56" to "firefox56/firefox56 -P ff56"
Icon= //firefox56.png (dont replace).
Mean: add "-P ff56", after firefox56.
8. Test 2 Profile + 2 Desktop shortcut.
2 file desktop: Copy and Paste to /usr/share/applications.
If icon show ok, mean ok, if not, check link of firefox and firefox icon.
Open App List, find firefox and run.
Fireofx 56: change setting: Allow Firefox to "Never check for update", and in add-ons uncheck "Update Add-ons Auto.." left search box add-ons.
Eg: Adblock 2.x in ff56(with profile ff56).
Adblock 3.x in firefox last(with profile default).
Problem: cannot dual version, running same time???
If you want run sametime(2 way)
1. just run first last version , next old version.
2.set profile for last version to default(add "-P default" to Firefox Last.desktop). see 7. (this way is best). now run any version you want.
