If you have a new computer then this is a total non issue and the folks at Mozilla are babying you. It's time to unleash the true Fox.
- tep 1
Open Fire Fox. Open a new tab. In the address bar type "about:config", without the quotes.
- Step 2
You will get a cute as a button error message that says:
"This may void your warranty! Changing these advanced settings can be harmful to the stability, security, and performance of this application.You should only continue if you are sure of what your doing."
Click on "I'll be careful I promise!" - Step 3
You will be assaulted by a mind bobbling list of googlygook techo babble. Take a moment to put on your geek eyes and notice that the entries are in alphabetical order. Scroll down until you see this:
browser.tabs.showSingleWindowModePrefs
When you see this double click on it so it = true
If you do not see this entry than one of your Firefox add-ons has already set it to true. All that this does is allow you to see advanced options. If you don't see it just move on to the next step. - Step 4
Now scroll down further until you see this:
network http.pipelining
Double click on it so it = true - Step 5
Now look down one and click on this:
network.http.pipelining.maxrequests
Double click on it and change it from 4 to 100.
This enables FF to use 8 threads per tab which means that now it can really burn some rubber. It will use a bit more memory but I've found that it's not too burdensome.
To test this I even made these changes to my three year old laptop and it didn't slow it down at all. In fact if Mozilla refuses to load video and you have an older computer this may fix it because it will allow allow it to use more memory.
Now that you've made the changes you can close the tab and load a YouTube video or hit your Stumble Upon button and enjoy the speed boost. Nice isn't it?
This change wont cause any damage but messing around with the other entries will so don't do it.
