network.http.max-persistent-connections-per-server keeps reverting to user set 4
I didn't used to have this problem as far as I'm aware, but as of recently, I've noticed that if I try to download more than 4 of one thing at a time from the same site, it would fail. For instance, if I have up 5 web pages of streaming content, only 4 will load, the other 5th one will do nothing until I finish one of the others. Upon looking up some information on this, I saw that the network.http.max-persistent-connections-per-server is set at "user set = 4", and if I change that number to anything else, it corresponds. If I click to 'reset' the number, it goes to the default of 6 - which is still less than what it used to be. I used to not even have a limit on this as far as I'm aware, or if I did, it was well beyond 10 and that wasn't a product of me manipulating it.
What I'm asking is this:
1) How do I make this so it permanently switches to a higher number? Every time I reset it to 6 or I manually change the number to something higher, once I close it, those settings go back to 4.
2) Why is it reverting and not staying the way I change it?
3) What's the purpose of this and why is it just recently doing it when I haven't put any new add-ons or made any other refinements to Firefox that I'm aware of?
Any help would be appreciated

Two possible causes for it resetting to 4 that I can think of.
- You have an add-on handing that pref and that is resetting it to 4 when Firefox is restarted.
- That pref is set via user.js and that causes it to go to that value as Firefox starts.

If you use that many persistent connections to a server then you prevent others from connection to that server.
You should stick to the default settings after you've found the cause (user.js or extension).
Some servers may block or ban you if they detect that you are using too many connections.
Editing the user.js file seems to have worked. Thanks!
