How to Speed Up Firefox – Make Firefox Fast


Firefox has outperforming IE in every department for years, and version 3 is actually speedier than ever. No matter which browser you choose as your favorite, they each can have problems at any time. They will fill up and slow down seemingly for actually no reason. They can crash and most of the time those are a direct result of some of the things we will fix in this article. In this article, we are going to talk about How to Speed Up Firefox – Make Firefox Fast. Let’s begin!

Firefox is no deviation. It is generally quite speedy, but there are some little things you can do to speed it up even further or help it along if it is lagging on you. This is my guide in order to speed up Firefox in under 2 minutes

Firefox Update

The first thing that you want to do is update the browser to the latest iteration. Mozilla also releases updates much more often than almost every other browser in order to improve the performance and safety of its product. If you want to update, then you are going to open up Firefox, select at the top-right corner, and then choose ”Help”.

  • First, select ”About Firefox”.
  • Then the browser will now automatically update itself!

  • Select the ”Restart Firefox” button in order to allow the process to finish.
  • Congratulations! You now have the latest version of this amazing browser.

Free Up Some Space or Memory

The next thing that we are going to do is clear up some of the memory being used by the browser. In the past, there were a lot of complaints about Firefox that it is using too much system memory, thus slowing your entire system (and the browser) down. This has mostly been resolved, but it could still occasionally cause you problems, especially on older machines.

  • In order to help this, open up your Firefox browser. Then in the address bar, you need to type about: memory.
  • You will be presented with a page that just looks like the below. If you are an advanced user, then you can take advantage of the reports offered here.

  • For the rest of us, we are simply going to tap that ”Minimize Memory Usage” button.
  • You will then see a message under each and every of these memory options that actually says“Memory minimization complete,” along with the date and time.

Clear Cache, History and Cookies | speed up firefox

The third and final instant step in our speed-up process is going to be clearing out your cache, cookies, history, and much more minor things from the browser. You will be surprised to know how much space these things can take up – sometimes very quickly, depending on how much surfing you are doing each day! This can significantly slow down the browser’s response times, so let us clean it up.

  • First, tap those three lines at the top-right again, but this time select ”Options”.
  • Then tap on ”Privacy and Security” on the left-hand side.
  • Scroll down to where you see ”Cookies and Site Data” and then choose that.
  • Tap on the ”Clear Data” button and a new box will pop up with your options. Place an X in both boxes and then click the ”Clear”.
  • Then, scroll further down the page to the ”History” section. Tap that ”Clear History” button.
  • Now choose carefully which items you wish to clear in the box that comes up. I chose to clear it all… there is nothing that is crucial for me to keep them.

When you have made your selections, then decide the time-frame of history to clear from the drop-down box. You can also choose between 1 hour, 2 hours, 4 hours, the past day or everything. I recommend you to choose ”Everything” in order to maximize the speed-up process.

When it has finished clearing, then you can even choose to have the browser never remember your History by selecting that option from the drop-down menu.

Now you are all cleared up! Your Firefox browser should be running much more faster now. If it is not, there is one more thing that you can do, but you may run a few seconds over that two-minute mark I promised!

Disable Extensions | speed up firefox

If you have enabled or installed many addons in the browser, one or more of them may be what is slowing you down. I will start by disabling all of them. In order to do this, first, you need to click those lines at the top again, then choose ”Addons”. On the left, tap on ”Extensions”.

  • If you look at each extension that you have installed, then you will see three dots on the right side. Click those dots and then choose ”Disable” next to each one.
  • When you have more time, you can re-enable one extension at a time (and then browse it for a while). If you want to see if it was the one that was slowing you down.
  • When all of the extensions have been disabled, then you need to tap ”Themes” on the left side of the page.

  • Make sure to select the ”Default Theme” option. Using any of the others can slow your browser by a few – or many! – degrees.
