Here's how to get rid of it. Read More is not funny. If you haven’t uninstalled it, then you at least need to change it to “click-to-play” in your Firefox. Not only is this essential as a security measure, but it will also speed up your browsing as Flash elements on web pages won’t load automatically.


You don’t need to install any third-party extensions to do this either. Mozilla lets you set plugins to click-to-play through its settings. Here’s how to do it:

  1. Open a New Tab and go to Tools > addons
  2. Choose Plugins from the sidebar
  3. Click the drop-down button next to Shockwave Flash that says “Always activate” and change it to “Ask to Activate”
  4. Optional: You can disable Flash entirely by choosing “Never Activate”

If not, go ahead and fire up the browser and take a look at all the options you can change. It’s pretty easy to customize Firefox, right? Especially... Read More already, but this time, we’re going to concentrate only on those that make the browser work faster.


How to Access and Use About:Config

  1. Open a New Tab
  2. Type “about:config” in the URL bar, without quotes, and press Enter
  3. Click “I’ll be careful, I promise” button
  4. Search for any string mentioned below
  5. Double-click “status” to change the status
  6. Click anywhere else to save the status


Once you’re in About:Config, change the following preferences to the denoted value so that your Firefox runs faster.

  • Set browser.tabs.animate to False
  • Set browser.download.animateNotifications to False
  • Set browser.preferences.animateFadeIn to False
  • Set browser.fullscreen.animate to 0
  • Set security.dialog_enable_delay to 0
  • Set network.prefetch-next to False (Only on slow Internet connections)
  • Set network.http.pipelining to True

Your Firefox should now be visibly faster, as you have just disabled unnecessary animations, stopped the countdown timer when you’re installing extensions, and told it to stop preloading web pages when you’re on a slow connection.

Alternately, download and install Speed Tweaks a.k.a SpeedyFox, an addon which does the same things as the tweaks listed above. But hey, why stress your browser with another extension when you can do the work?

Handle Your Addons

Firefox shot to fame because of its large collection of addons and extensions, and it enjoys that distinction even today. Unfortunately, addons also take up a lot of memory and slow down your browser. For example, there’s a well-documented case of how Adblock Plus drains memory.

Here, you’ll see a list of all your addons and how much memory they are consuming. It works best when you’ve had Firefox open for some time and have been using it. Once you have your data, make the changes you need so that you can install lighter extensions or switch to bookmarklets.

Switch to Bookmarklets

Bookmarklets are lighter, safer, and work just as well as several popular addons.

We have a large list of bookmarklet alternatives to addons, so start replacing those extensions!

Manage Your Tabs

Apart from extensions, the other thing that really slows down the browser is the number of tabs you have open. It’s all right to have several tabs open, but you need to manage them correctly to ensure Firefox doesn’t start crawling. Funnily, what you’ll need to accomplish this is two addons.

Auto Unload Tab


You keep a lot of tabs open, but you don’t always need them all the time. Auto Unload Tab will automatically stop that tab from taking up CPU cycles, RAM, or from reloading. You can even set a maximum number of tabs to load in any session. Right-click in the tab or page to see a context menu with all the options you need. And yes, you can add individual tabs or certain sites to the blacklist so that they are ignored by Auto Unload Tab.

    I tried all of it and mine is still slow as a snail. Why did they stop supporting Chrome on xp?

    Didn't help, couldn't find any of the suggested integrations. Likely as not, they're absent from the current Firefox release for Android. Will research further for FF 4 Android config tweaks.

    With tweaks made to Chrome 4 Android, I'm finding myself using Google Chrome more. Except for situations where adblocker is needed then FF takes over.

    Thanks for the tips! They did help.

    Notes: Editing Set security.dialog_enable_delay crashed my Firefox 49.0.2 on Mac OS X, so I didn't.

    browser.pocket.enabled is not in about:config, it may be called extension.pocket.enabled now (I set it to False).

    I had been danceing around following the Mozilla script on 'what to do if' and load time was still bad. Wasted time with the safe start one by one enable of add-ons/extenstions. Nope.

    Followed these suggestions and bingo, it is running, as in quickly.
