If you run XP and firefox, the best thing to do is run 2 versions. You can achieve this by running it with -P "profilename" command. You run the old version like 20-25 for sites you're familiar and use often like forums, craigslist etc. and its quite fast. Then run 47-52 for newer stuff like bitchute and sites that play MP4 or use newer tech. To start profile manger run firefox -p and then -P once profile name is setup. Setup 2 different profiles one for 25 and one for 52 and on the desktop refernce the shortcut with the extra paramters. If you ever run firefox again without the -P it will always overwrite and delete your old stuff.
If you try this save your bookmarks first twice because the newer fox and older ones use different formats.
I use the following commands, f2 is my original profile and fiftytwo is my 2nd in a different folder.
"C:\Program Files\Firefox25\firefox.exe" -P "f2"
"C:\Program Files\Firefox52\firefox.exe" -P "FiftyTWO"
With 52 you can play MP4 in the browser. This is unofficial but I can confirm it works.

In the firefox profiles folder create a folder named gmp-eme-adobe and in there create a folder named 17, unzip the 3 files to 17 folder.
Add the following to firefox about:config and it should load on restart.
media.gmp-eme-adobe.enabled (boolean; true)
media.gmp-eme-adobe.forceSupported (boolean; true)
media.gmp-eme-adobe.forcevisible (boolean; true)
media.gmp-eme-adobe.visible (boolean; true)
media.gmp-eme-adobe.version (string, 17)
media.gmp.decoder.enabled (boolean; true)
media.eme.enabled (boolean; true)
I run a very stripped down firefox 25 for youtube with adblock and noscript and it plays vids great even on this old laptop. For the newer vids that say can't play or bitchute I will use 52 and it plays them fine.
