Recently Firefox (version 31.0) has been kicking me out of certain webpages, such as Wikia sites, or just recently, Hulu. I could browse Hulu fine, but as soon as I tried to go to a page on the site with a video, it kicked me. I always end up on a Yahoo (my default search engine) search talking about a DNS error (I enclosed a screenshot of the Hulu instance moments ago).
I did web research but couldn't seem to find anything relating to my exact issue. I tried running Disk Utility, as well as cleaning out Firefox's cache, cookies, and browsing history, and even entered a command into Terminal I found on this page, though it says it's for Leopard, so it may not work for me because I use Mavericks. I read something about proxies, but changing my setting to "no proxy" (I don't know if I have that or not; not too knowledgeable on all the fancy tech stuff and terminology).
I should also note the pages seem to load fine in Safari.
It seemed like this started happening after I downloaded Unity Web Player so I could play an online game that requires it. I don't want to delete this, because I want to keep playing the game.
Is there anything I can do to make Firefox load all the pages like normal again?

Thread: Firefox DNS error

Restore your startup homepage -> on Menu Bar ->Tools and Options. A window appears and in General change the settings for it.
Delete entries (non wanted search engines) in the search bar next to the address bar.
If the same issue occurs, restoring Firefox can help. Save your bookmarks first (keyboard Ctrl+Maj+B) save, and so... type aboutupport on the address bar and click on Reset Firefox (or something like that because I use the french version of Firefox).

Firefox does have a DNS cache (the command you found is unlikely to fix issues with the FF DNS cache) and you need to do this to flush it:
Those instructions are old so if they don't work, you can disable the damn thing this way:
Most major ISPs in the USA offer sh*t DNS services. AT&T's is awful (I'm a customer, so I know). Comcast's is also bad. The best thing you could do for yourself is to change your DNS server to a good free one. Change your Mac to use either Google
or Open DNS
I use Open DNS but they're both good.
To be honest with you, I feel that FF is really declining all the time. Yes, I still use it, but Chrome is such a better product with so much less bs to deal with. FF's developers are always making crazy decisions that cause problems for some people. Your problem is just one of many.
I followed the instructions on those websites about the DNS cache. No luck whether the DNS is set to 60, 3600, or 0. Tried all 3. It does seem like the page lasted longer before leaving to Yahoo's funny search result (enclosed another screenshot, this time after it jumped out of a Wikia page).
I entered the Open DNS numbers into my settings. Still no good.
Would reinstalling Firefox do any good? I seem to be running out of options."They will walk after the LORD, He will roar like a lion; indeed He will roar and His sons will come trembling from the west." - Hosea 11:10
google dns 220.127.116.11
3600? ... you must be in some other setting ... ip adress in this format > xxx.xxx.xxx.xxx
How do you connect to the net ? ... guessing is hard.
My suggestion is give up and use Chrome. That's what I've done on Mac. If you're married to some Firefox extension you can't live without that doesn't have a Chrome equivalent, then I guess try reinstalling it or switch to Seamonkey as El Heggunte suggested. Switching to Open DNS should be fine so definitely keep that and you might try DISABLING the cache altogether as described in one of my links above. You didn't say that you tried that.
the way to do it with Maverick.
That's not a long term solution, though. As Jman98 said you're better off going with Opendns. If your Mac is connected to a router, then get into the management page, then look for the LAN configuration and enter the DNS in the spot provided. Every device that connects to your network will get the new DNS server.
Re-installing FF will probably do nothing if the problem is with DNS, but it can't do any harm if you export your settings first.
