I have found that, generally, using a local caching name server, a local caching proxy (such as squid or polipo), and adblock+noscript has a far greater improvement in perceived performance on my overall daily browsing habits than specific Firefox or network stack tweaks.
Firefox has a couple of hidden network settings. With Tweak Network, you can tweak these settings, and you might be able to speed up the loading of web pages. You can also increase the maximum number of simultaneous downloads from a site (the default is only four).
Firefox has a couple of hidden network settings. With this extension, you can tweak these settings, and you might be able to speed up the loading of web pages. You can also increase the maximum number of simultaneous downloads from a site (the default is only six).
So if this extension improves your web browsing, why aren't these network settings improved by default in Firefox? This is because Firefox wants to adhere to the HTTP specification which says: "Asingle-user client SHOULD NOT maintain more than 2 connections withany server or proxy." Unfortunately, the specification (from 1999) is outdated at this point.
Firefox's user interface can be modified by editing the userChrome.css and userContent.css files in /.mozilla/firefox/profile/chrome/ (profile_dir is of the form hash.name, where the hash is an 8 character, seemingly random string and the profile name is usually default). You can find out the exact name by typing about:support in the URL bar, and searching for the Profile Directory field under the Application Basics section as described in the Firefox documentation.
In order to for example disable the behavior that selects the contents of the address bar on first click, or to allow to double click the URL to select it in full, see user contributed scripts such as -omni-tweaks
In order to get smooth physics-based scrolling in Firefox, the general.smoothScroll.msdPhysics configurations can be changed to emulate a snappier behaviour like in other web browsers. For a quicker configuration, append the following to /.mozilla/firefox/your-profile/user.js (requires restart):
In about:config set network.protocol-handler.expose.magnet to false. In case it does not exist, it needs to be created, right click on a free area and select New > Boolean, input network.protocol-handler.expose.magnet and set it to false.
The next time you open a magnet link, you will be prompted with a Launch Application dialogue. From there simply select your chosen BitTorrent client. This technique can also be used with other protocols: network.protocol-handler.expose..
These Firefox performance tweaks should work for any Firefox user who wants to pump as much juice out of the browser as possible. Not only will they help speed up Firefox but they will also decrease the amount of memory (RAM) Firefox consumes thus speeding up your PC in general.
By default, Firefox will wait 250 milliseconds (0.25 seconds) before displaying any page. This tweak adjusts how long Firefox waits before displaying a page. Originally this delay was implemented on the premise that pages will load faster if they are not loading real-time but rather wait to display until the entire page loads. With a high-speed connection, the delay only becomes nothing more than an unneeded delay.
I recently found about State Partitioning and how to disable it with privacy.partition.network_state = false in about:config. For those who use "Open image in a new tab" and have slow internet connections, it's a must. It will prevent Firefox for reloading the image again.
Firefox is incredibly slow to start on my system, but *only* when I have an active internet connection. See the difference in times from running time firefox and then closing the window once it pops up (with a MET-X; I'm running spectrwm, so the delay is pretty neglible).
Removed my 3 plugins, deleted my existing profile, downgraded/upgraded firefox. Even crashidori err midori starts in range of 0.5 - 0.8 seconds, will be glad if anyone could point me any tweak that will solve this annoying delay.
There is an easy fix for it just increase media.cache_readhead_limit to 9999 and media.cache_resume_treshold also to 9999.This was also puzzling me since firefox 54 would buffer till the end of the video but firefox 55 wouldn't, so I went trough the about:config and found those two lines once I chagned their values from (60, 30) to those above every single video I opened in firefox so far buffered till the end, you don't even need to restart the firefox just refresh the page for changes to take the effect.Hope this helped.
A more up to date reference is this:
To restore the previous behaviour just add a text file named userChrome.css in a newly created folder named chrome in your /home//.mozilla/firefox// directory with the following content:
Tailing only briefly prevents the tracking scripts loading, rather than disabling them entirely. Page load performance is improved by saving on network bandwidth and computing resources while loading a page, in a way that prioritizes site requests over tracking requests.
I disabled font hinting in Gnome tweaks, but Firefox sometimes (for certain fonts I think) ignores that and tries to align glyphs to pixel grid, resulting in uneven spacing between letters and/or distorted glyphs. I'd like to force Firefox to never use hinting, if possible, are there ways to do so?
Just to check it with something really obvious, I tried to disable font antialiasing in Gnome tweaks (which makes fonts obviously hideous) and it doesn't change font appearance in Firefox, so I'm pretty sure Firefox ignores Gnome font settings.
Firefox currently offers a VPN (virtual private network) called Mozilla VPN. However, this is just a rebranded version of Mullvad and I have seen many users complaining on various forums about the lack of support when things go wrong.
While many of the configurations and add-ons discussed in this guide will go a long way to giving you more privacy, there is one issue that remains: concealing your IP address and location. To do this, a good VPN service is necessary. The Tor network also achieves this end, but it comes with the drawbacks of slow speeds, risks, and limitations (only works in a browser).
The Connection general header controls whether the network connection stays open after the current transaction finishes. If the value sent is keep-alive, the connection is persistent and not closed, allowing for subsequent requests to the same server to be done.

imho ghacks.net does the best job discussing and reviewing firefox. They have maintained for years a user.js. Just reading it is worth it. Before FF changed their extension support, there was a really nice addon called Configuration Mania which basically put a gui on many of the preferences. Most of my pref changes come from this file.
Use CSS
Newer Firefox versions allow to use CSS to change the way Firefox displays the GUI (see here for details).
You need to use the file userContent.css in the subdirectory chrome of your profile folder. With the setting scrollbar-width: auto; you can increase the Firefox scrollbar width (see here for a description).
Here you can find an easy to handle project to tweak a lot of the Firefox GUI CSS settings, including the scrollbar width (update the settings in ./config/custom_scrollbar_appearance.css and enable its import in your userContent.css).
Please note, that with newer Firefox versions config settings may prohibit this mechanism (e.g. see about:config preference layout.css.scrollbar-width.enabled).
Please note further, that if you specify scrollbar relevant settings via CSS, then the GTK3 settings via /.config/gtk-3.0/gtk.css are ignored.
You can change intricate settings in Firefox through its accessible Configs menu. We've featured a few essential Firefox tweaks already, but this time, we're going to concentrate only on those that make the browser work faster.
The new version of Firefox integrates add-ons like Pocket out of the box, whether you want them or not. Removing them can speed up the browser's startup time and memory usage. Start with these tweaks:
These tips and tricks are excellent ways to speed up your slow Firefox browser. But the most common reason your browser runs slow is the tabs. Unless you make an effort to handle your tabs well, none of these tweaks will have a long-lasting effect. So whatever you do, make sure you learn tab management in Firefox Quantum. And try these special tools from Mozilla to improve your overall browsing experience. Be sure to add some Firefox keyboard shortcuts to your workflow, too.
First of all, by default, browsers won't send a referrer if you place arequest from an HTTPS page to an HTTP page. This would reveal potentiallyconfidential information (such as the URL path and query string which couldcontain session tokens or other secret identifiers) from a secure page overan insecure HTTP channel. Firefox will however include a Referer header inHTTPS to HTTPS transitions unless network.http.sendSecureXSiteReferrer(removed in Firefox 52) is set to false in about:config.
