1)

Firefox is usually very polite! it just send a request to server and wait to receive a response before sending another request. To set Firefox to send multi request at once follow these steps #1 to #3: Open Firefox as a blank page or a blank tab. Type about:config in the address bar:

If you are seeing a warning page and the button I’ll be careful, I promise! like the picture below:

press that button to see another part. In filter bar type: network.http.pipelining to find it under preference name column:

As you see in the picture above, the default value is False. So, double click on it to change it to True:

2)

In the text area that is in front of filter bar, type: network.http.proxy.pipelining. and change it to True:

3)

Now find network.http.pipelining.maxrequests. Right click on it and click Modify:

The default value you are going to see would be 4. So, change it to 8:

4)

At the same page (about:config) Right click on a blank space and select: New –> Boolean: (now you are making a Boolean value. Through next steps you need to make some Boolean values again. I mean you should type about:config in the address bar and hit Enter then right click on a blank space and select: New –> Boolean)

5)

At the same page (about:config) Right click on a blank space and select: New –> Integer: (now you are making an Integer value. Through next steps you need to make some Boolean values again. I mean you should type about:config in the address bar and hit Enter. Then right click on a blank space of the page and select: New –> Integer )
Name it nglayout.initialpaint.delay and press OK:

Finally set it’s value to 0:

6)

Large and intricate web pages can take a while to download. Although Firefox doesn’t have any delay here but since in default it should shows you what it’s received every 0.12 seconds and this causes to increase loading the web pages. Well, to avoid this: Just as like as step 5 make another Integer value name it content.notify.interval and set it’s value to 500000. Pay attention to the value ( It is five hundred thousand and not fifty hundreds )

7)

Just like #4 make another Boolean value. Then create a value called content.notify.ontimer and set it’s value to True.

8)

If you haven’t moved your mouse or touched the keyboard for 0.75 seconds then Firefox enters a low frequency interrupt mode, that means its interface becomes less responsive and your web page loads faster. Reducing the content switch threshold can improve performance, then, and it only takes a moment: Make another Integer value. Name it content.switch.threshold click OK and set it’s value to 250000 (one fourth of a second) then click OK to finish the job for now.

9)

It is also possible to extend the last tip to user interface. Telling Firefox to ignore all user interface events until the current page has been downloaded, causes Firefox load web pages faster. (may this would be a little effective but it is recommended to test it for your browser and see how does it work for you): Make an other Boolean value called content.interrupt.parsing and set it’s value to False.

10)

There are many unwelcome flash on many web pages. As we know this causes slowing down browsing. So, what is the solution? there is a very simple solution. That;s just installing a Firefox extension is named Flash Block. To download or install this Firefox extension click here:

11)

As you know while you are browsing Firefox stores some script and images of the web pages in a local memory cache. And they can be retrieved faster if you open the same page. If you have plenty of Ram leave Firefox running to improve the performance. Make another Integer value and name it browser.cache.memory.capacity and set it’s value to 65536. Finally restart your browser to apply the changes and get large cache.

12)

There is an other helpful Firefox extension named FasterFox. Fasterfox allows you to tweak many network and rendering settings such as simultaneous connections, pipelining, cache, DNS cache, and initial paint delay. To download or add it to your Firefox click here. But the way! to add it to your Firefox you need to sign in!

The last tip I’m going to write about is using anohter Firefox extension named DownThemAll. This is the description I’ve seen about it: This is all you can desire from a download manager: it features an advanced accelerator that increases speed up to 400% and it allows you to pause and resume downloads at any time. To download it or add it to your Firefox click here.

And don't forget what made Firefox special is at free and millions useful add-ons for various needs, get it at https://addons.mozilla.org/en-US/firefox/ but don't install too many of them or your Firefox might run slower.
