The Best Mozilla Firefox Tips and Tricks 2016

You may have seen many articles on Top Mozilla Firefox Tips and Tricks, but we have filtered the best tricks and bucketed them under 5 major categories – Settings, Configuration, Performance, Features and Shortcuts to help users tweak Mozilla Firefox based on their needs.


1. Optimize RAM usage when minimized

Firefox continues to consume memory even when it is minimized, but you can move this memory to your hard drive by typing ‘about:config’ in the URL and then right-click anywhere in the blank space. New -> Boolean, name it “config.trim_on_minimize” and set it to ‘True’. Restart Firefox for the change to take effect.

We won’t recommend editing the “browser.cache.disk.capacity” as Firefox in many cases restores its default value. Instead, clear your cache regularly to improve performance.

2. Minimize Page Rendering Duration

Firefox by default waits for about 250 ms before it renders a page and acts on the information it receives. You can set it to 0 by typing ‘about:config‘ and create a New -> Integer with right click on blank space, name it ‘nglayout.initialpaint.delay‘ and then set it to 0.


1. Enable TAB Preview

Type “about:config“, in the search bar type “browser.ctrlTab.previews” -> set it to true. Now you can preview tabs by pressing ‘Ctrl+TAB‘. Remember you need to have at least 3 tabs for preview.

2. Enable Multiple Websites on Firefox Homepage

You may want to open multiple websites when you open your Firefox browser to check emails, news, and updates. Let’s say you always or most of the times Google or check your Gmail when you open your browser, but you have to go to a new tab to check your Gmail every time. You can guide Firefox to open Google and Gmail at the same time whenever you open the browser by going to Options and aggregating Google and Gmail with a pipe symbol ( | )


1. Master Password

a. Set a Master Password to protect your information by going to settings through three horizontal bars on top right corner

b. Press reset
c. Follow the steps above to set a new Master Password

2. Change default E-mail platform

By default Firefox Uses ‘ChromeHTML‘ to send emails but you may not be accustomed to this platform, rather, you prefer Gmail. 

You can change the default E-mail platform to Gmail, Yahoo or other E-mail platforms by going to Firefox settings -> Under Application, scroll down to ‘mailto‘ option. Select the drop down and change your default E-mail platform

If you couldn’t find the E-mail service in the drop-down, install ‘MailtoWebmails‘ add-on. It will allow you to choose from multiple E-mail platforms!


1. Auto-complete

Firefox automatically adds www and .com with a Keyboard shortcut (Ctrl + Enter) to make the URL complete. For instance, type Gmail and Ctrl+Enter, Firefox will auto complete and load the URL (

2. Tab Navigation

Use Ctrl+PageDown and Ctrl+PageUp to navigate within tabs

3. Use special characters to refine your search

If you want to search a particular page in your Bookmarks or History, but are not able to, you can refine your search by using some special characters in the address bar. For instance, you have bookmarked a Moftare page, just type ‘moftare *‘ in the address bar, it will highlight all Moftare bookmarks.
