Why does Firefox keep telling me I'm running an old version when I've updated 3 times this week & 'About FF' tells me I've got Ver 50.1.0?

I'm running Win7 SP1 on i5 CPU. Error message that FF can't tell which version. My home page, the Mozilla plug-in checker, tells me I'm using an old version. In 'About Firefox' it says I'm running 50.1.0. I've downloaded & updated 3 times this week but when it auto-loads after update I still get error message. Can't watch videos - some work, most don't. Error says something about it can't find any MIME files. In Facebook I get either a blank space or a black square. GIFFs & the occasional vid do work. I followed the " about.config" instructions but it made no difference. I had no problems with the previous version. The "Educated Guesses" I found below are wrong. I won't use 8.1 or 10 - 7 is way better for me.

"Something" messed with your UserAgent in Firefox and it's telling websites that an older 36.04 version is being used. And that's not even a valid version of Firefox as it is missing a period between the 0 and the 4. 36.0.4 would be correct version number from March 21, 2015.

See this KB article to learn how to fix that. https://support.mozilla.org/en-US/kb/how-reset-default-user-agent-firefox

You should have a look at this(re your Npapicomadapter.dll plug-in) - https://www.herdprotect.com/npapicomadapter.dll-a768c2becd3637a773bb6d2aa7549bbe756dc46b.aspx

About FF tells me I'm running 50.1.0 & this is up to date, this was also the update version I tried to install (3 times). I don't understand why 51.0 is mentioned because that is not the update version you sent me.

Firefox 51.0 was released Tuesday Jan 24 as you can see at https://www.mozilla.org/firefox/51.0/releasenotes/ and then updates to 51.0 was later disabled due to the Geolocation issue in which a 51.0.1 update is coming. The 50.1.0 is a old Release.

Can anybody explain this screenshot please. Also the 51.0.1 update has stuffed up my Quick Passwords add-on, I have dozens of passwords & no hope of remembering them all so this was an essential tool & FF has now made logging on to anything a major hassle. I still can't watch vids & still get that MIME extension error. It has gone from bad to worse & it seems like Mozilla has done a Microsoft & stuffed up a perfectly good program. Is it possible to de-grade back to version 49? I've found it is very much slower than previous versions too.
