How to enable Parallel Downloading in Firefox

Unlike Chromium browsers enabling parallel downloading in Firefox is a bit complicated. But fret not, we make it easy with the below step-by-step guide. Here’s how to enable parallel downloading in Firefox:

• Open Firefox and enter the about://config command in the search bar
• In the next tab, click on ‘Accept the Risk and Continue‘.
  
• In the search box, enter the command network.http.max-persistent-connections-per-server
  
• Click on the pencil icon on the right side of the result and change the value from the default 6 to a higher number such as 10.

(Note: The number in the box indicates how many parts/threads the file will be divided into while downloading.)

• Hit Enter on the keyboard and then restart Firefox to successfully enable parallel downloading and enjoy faster download speeds.

On Android

The stable version of Firefox on Android doesn’t allow enabling parallel downloading. However, you can use the Beta or the Developer builds to enable to use the parallel downloading feature on Firefox. Here is how you can do it:

• Open Firefox Beta or Firefox Nightly on your Android device and type about:config in the search bar.
  
• Enter the command network.http.max-persistent-connections-per-server in the search bar.
  
• Tap on the number and change the value from 6 to a desired higher number like 10.
  
• Click enter on the keyboard and restart Firefox to enable parallel downloading.

If you want to enable parallel downloading in the Brave browser, follow the below instructions.

• Launch Brave browser and type Brave://flags in the search bar.
  
• Search for parallel downloading in the search box.
  
• Choose Enable in the drop-down menu 
  
• Click on the Relaunch button to activate parallel browsing on Brave.

On Android

• Install and Open Brave browser on your Android device.
  
• Type Brave://flags in the search box and hit enter.
  
• Enter parallel downloading in the search box.
  
• Choose Enable in the drop-down menu.
• Finally, click on the Relaunch button to restart the browser and activate the parallel downloading feature in the Brave browser. 

Advantages of Parallel Downloading

• One of the main advantages of parallel downloading is it significantly improves download speeds for large downloads by dividing the file into several parts and downloading them simultaneously using multiple sources or server connections. While this technique may not be as useful when downloading smaller files, larger files benefit significantly from it.
• Parallel downloading significantly reduces the chances of download failure by making efficient usage of your allowed internet bandwidth so the file downloads as quickly as possible.
• Parallel downloading is especially useful when you have a slow internet connection.
• Less chance of file corruption.

Disadvantages of Parallel Downloading

• While most websites allow parallel downloading, some host servers may block this or limit the number of concurrent connections each download instance can have to conserve bandwidth. In this case, files may download at normal speeds.
• Since parallel downloading makes maximum usage of your internet bandwidth to offer faster downloads, other apps on your PC or your Android device that depend on this shared bandwidth may run slowly.
• Parallel downloading may heat up your devices, especially mobile phones, due to higher download speeds.
• Parallel downloading also consumes more data compared to normal download methods. But, it should be noted that the amount of data consumed is negligible.
• As said above, smaller files may not benefit significantly from the parallel downloading technique.

While there are some drawbacks to parallel downloading, we highly recommend trying this download technique in your preferred browser if you’re looking to increase the download speeds.

Best third-party download managers with Parallel Downloading

For desktop

Internet Download Manager (IDM)

IDM is one of the best third-party download managers for Windows. It utilizes the parallel downloading optimization technique to achieve faster download speeds. Apart from that, this versatile download manager is great at smoothly handling any download failures, network issues, unexpected PC shutdowns, etc. The only downside to this excellent piece of software is that it is only available as a paid option. However, there is a 30-day free trial to see if it’s really worth the price.

FAQs

1. What is Parallel Downloading?

Most browsers typically use a single thread/connection to download files from the server. While this technique works efficiently for smaller files, for large files, this can lead to slow download speeds. This is where parallel downloading can make a difference. The technique splits a large file into smaller parts and downloads them simultaneously using multiple server connections, offering significantly increased download speeds.

For instance, if you’re looking to download a 500MB file from the internet, you can significantly improve the download speed by utilizing parallel downloading. Say, the browser allows up to five parallel connections to the server, then the file is divided into five smaller 100MB parts. All these parts are then downloaded at the same time, offering increased download speeds. Finally, all the file segments are intelligently merged into one complete file.

Also known as multithreading, parallel downloading maximizes the download speeds by making efficient usage of your available internet bandwidth.

2. Does Parallel Downloading work on all websites?

Most websites should work fine with parallel downloading. However, some websites restrict the number of concurrent connections a single IP (Internet protocol) address can have for a download instance to save bandwidth costs and server load.

3. Does Parallel Downloading consume more data? 

Yes, parallel downloading does consume more data compared to single-threaded download techniques. However, the extra data consumed should be negligible.

4. Does Parallel Downloading slow down your device?

Yes, if the device is not powerful enough, it should cause minor heating and performance issues. The heating issue is caused because of the increased processing required for higher download speeds. But as soon as the download finishes, things should get back to normal
