Optimize your Firefox browser to the maximum


Firefox is one of the most popular web browsers on the netSince is a multiplatform browserWe can use it both on the computer and on mobile devices. It is true that with the new updates that the browser has been doing, it has positioned itself in a good place.

With this it has gained a lot of popularity and it has convinced quite a few of being able to use it, in my case I am not the exception, but something that I do not like is that it includes some functions that in my case are irrelevant that only make the browser heavier.

Although I am happy with the good work that has been done with Firefox Quantum, from a personal point of view he has quite a few things to polish.

This is when I conflict, even though I consider that I have enough resources to be able to use the browser without problems, I am one of those people who does not like the unnecessary expense of them if it is not for something productive or that is really there.

That is why I share with you some configurations that we can make to our browser and be able to lighten it.

Turn off Hello, Pocket, and Firefox's reading view.

Among the first characteristics that I consider unnecessary is the Browser reading view, from my personal point of view, this function should only be activated on computers with touch screens, and its use is optional.

Another function is Hello, with which we can make video calls just by sharing a link.

The other is the Pocket plugin which saves web pages to Firefox.

And as I say in my case I do not occupy any and having them is really unnecessary, to deactivate these options there is a plugin for firefox We download it from the following link and deactivate these three.

Another way is to write in the address bar about: config and in the internal search engine we type pocket

And in the option extensions.pocket.enabled we click to change to False.

Limit suggestions

We can search from the address bar, this will show us a certain amount of suggestions, but when within your suggestion you include a diagonal or a point, it takes them as if it were a url, so it is poorly implemented, but we can limit this from about: config

Searching for browser.urlbar.maxRichResults We can modify the amount of these that we want to be shown.

Remove unnecessary extensions.

It is clear that the use of extensions is wonderful, but abusing them is loading the browser and consuming memory to the beast, every time I see an acquaintance with his browser full of them I see the following:

tool bars

Given that the needs are varied here I do not get in much.

Unnecessary animations

These animations use team resources, so from my perspective they are not practical,

To deactivate them also in the settings we look for the following: toolkit.cosmeticAnimations.enabled and we change the value to false

Improve the use of Pipelinin

Firefox makes use of this mode for several time with it the browser make multiple requests before they are answeredIn short, when browsing a web page, it has CSS style sheets, js, html files and others.

With Pipelining we reduce the loading time of the pages, although it only works on servers that support this feature.

To do this we just have to do the following in about: config we look for pipelining "and in the options"network.http.pipelining"This value must be true if not, you change it, now we must search:

network.http.pipelining.maxrequests set value = 8 (can be values ​​1 to 8, default is 4)
network.http.proxy.pipelining set the value = true (only applicable if you use a proxy)

Check the following keys:
network.http.keep-alive It has to be true for the pipeline to work.
network.http.version It has to be 1.1 for the pipeline to work.

Free up memory by minimizing

We can make Firefox reduce memory consumption by minimizing the browser. For this we change the value config.trim_on_minimize a true.


Use the user.js file

If you use a high-speed connection, Firefox does not take full advantage of it since there are still those who still use dial-up connections, which is why I share the configuration of this file for both situations. We must download the following zip file that they share with us and place the file in your folder Profiles.

    First of all, thanks for the post.
    I have several "profiles" folders on the system, could you tell me in which folder I should copy the user.js file?

    Ignore the article, they are tricks for old versions of firefox, not for the latest

    Some options, the latter, are in effect not available in current versions. But I'm not a friend of extra animations either ... so it's a pearl just for that.
