The past versions of Firefox brought a feature to it that a great deal of users didn’t like because it changed the way tabs are handled in a window. Instead of just showing all tabs at once, Firefox now adds horizontal scrolling to the tab bar in order to prevent the tabs from becoming too small to read its name. That way you can always see what’s on your tabs but don’t have a complete overview of the whole bar anymore.
In order to help out on that an add-on was created that increases the number of tabs that are visible before the overflow scrolling occurs.
It’s called Prevent Tab Overflow and you can find it in the Firefox Add-On database: https://addons.mozilla.org/en-US/firefox/addon/noverflow/
Add it and it will get to work instantly. Have a look at the Add-on preferences (Tools>Add-ons>Extensions>Prevent Tab Overflow>Preferences) to see what you can actually do:
While the add-on cannot prevent tab overflow as whole, it can resize the minimum tab width down to 40 pixel (the default in Firefox is 100 pixel). A lot more tabs fit in that way and the scrolling kicks in on a point where it actually makes sense not to shrink the tabs any further.
Usually you only have one browser profile that you use for everything – you have your passwords on it, save your tabs and bookmarks there and also pile up history and cookie data. If for some reason you want to divide some of this stuff between user profiles and use those with different command line arguments, Firefox let’s you do exactly that.
Before you proceed, take a look at the warnings on the Mozilla page – I had no issues with it however.
To access this feature, close all Firefox windows. Then open a cmd or terminal window, depending on your operating system, and open Firefox with the -P argument (if the Firefox location is not in your PATH variable, you have to direct the command line window to the application’s directory first – you can do that using the cd (change directory) command, for example like this:
cd “C:\Program Files\Mozilla Firefox\”
The Firefox Profile Manager will open:
Create a new profile using this manager. Afterwards, whenever you run Firefox without any argument, the highlighted profile will be loaded. You can determine which profile should be used by using the -p argument followed by the profile name, following will load the profile faqforge for example:
firefox -p faqforge
To ease profile selection, you can create multiple Firefox icons or symlink and assign them the appropriate command line arguments to open with.
Users of AVG 2012 antivirus software will already have noticed the AVG Advisor pop-ups informing you about high memory usage of browsers (I usually get them from 300 MB RAM upwards) which come up relatively often and are quite annoying since your browser uses more memory the more tabs you open.
But as in most cases you can simply disable this feature along with the memory monitoring. To do this, open the AVG control panel from the tray icon. On the top bar, click on Tools and select Advanced settings…. In there, select Appearance from the left panel. Under System tray notifications, uncheck the Display AVG Advisor notification to turn those off and click Apply. You will now no longer be warned about your browser’s memory usage.
Firefox is a browser designed for a large variety of systems and even meant to run on really old ones. This brings along the conflict of improved performance on newer systems and backwards compatibility.
Since Mozilla itself considers the latter more important, other third party developers are providing forks of Firefox that concentrate on effectiveness on newer, including 64 bit, systems.
Waterfox is project based on Firefox and made specifically for 64 bit systems with Windows installed. Its main goal is to improve speed and performance on capable systems. The major plugins such as Flash, Java and Silverlight are all available as 64 bit versions while all add-ons and themes working with Firefox are also compatible with Waterfox. Waterfox uses the same profiles as Firefox – meaning you don’t have to re-enter passwords and such, but also cannot open both programs at once.
Download Waterfox on the official project homepage: http://waterfoxproject.org/
The Pale Moon project is maintained by a single person and is also designed to boost speed on newer Windows systems, cutting some minor functionality of Firefox away and being available as 64 bit version. It does not pick up Firefox’ profiles automatically but does a tool to do so, which is provided on the homepage however. From my personal tests Pale Moon consumes only half of the RAM Fire- and Waterfox needed.
You can inform yourself about and download Palemoon on its homepage: http://www.palemoon.org/
Apart from the usual Bookmarks and Bookmarks Toolbar, the SpeedDial screen introduced a great visual option for quick access to your most commonly used websites. It currently is the main new-window-replacement on the Opera browser and can be downloaded as an add-on for Firefox.
It can be downloaded on the Mozilla Firefox add-on page here: https://addons.mozilla.org/en-US/firefox/addon/speed-dial/
The screen is highly configurable in terms of when to show up, which actions to perform on click and keyboard input, largeness of panels, number of panels etc. You can also put them together to groups which are then displayed as tabs in a seperate group bar.
If you like being lazy and want to browse sites you don’t have in your bookmarks already in the fastest possible way, there is a Firefox option that lets you determine what happens with expressions entered into the url bar.
There, you can enter the Google url that will open the correct search result for the keyword you entered into the url bar without having to enter those nasty “http://”s and “www.”s and “.com”s. Meaning, if you just type faqforge, it will open this site right away.
To enable this feature, enter about:config into your Firefox url bar to access the configuration. In the filter field, type keyword.url. Double-click the only remaining entry to change its value and set it to
Close the configuration afterwards and test the settings by entering some sitename into the url bar.
Plugin-container is a Firefox process designed to ‘out-source’ the plugins used by the browser. Firefox’ model is based on the use of plugins to add functionality, however this goes along with a chance of instability due to a malfunctioning plugin – this would cause the whole browser to collapse since the plugins were all included in one central Firefox process. With the implementation of the plugin-container, the plugins are seperated from the browser process, making it more stable. Now if a plugin crashes, Firefox remains unharmed.
It is known however that this feature causes serious performance issues with many users, that’s why it might be a good idea to test what happens if you deactivate plugin-container (the plugins are not disabled that way, they are just stitched to the main process again).
To do so, open Firefox and direct the URL line to about:config. This is the internal configuration of Firefox, be sure to take the warning that will be shown seriously.
In the search bar on top, enter dom.ipc. A few boolean entries will be shown whose name begins with dom.ipc.plugins (on Firefox 9 there are two, while there are five on some older versions).
Set all of them to false to disable plugin-container:
If this results in performance improvement for you, leave the settings as they are, if there is none however, it is recommendable to switch them back to improve Firefox’ stability.
It often happens that people use search engines just to access a site they know the url of but are too lazy to type it in with all the dots and slashes, although this adds one step to the process of opening the site.
However there is a Firefox Add-on called FireJump that lets you configure what page is opened when you search for a specific keyword, allowing you to skip the search results and direct the browser right to a specific website.
Download the plugin at http://firejump.net/
Unfortunately it is currently only available in German, but the few buttons are self-explaining.
On the above screenshot you are given the option to either open the default search results or to skip to the FireJump homepage when you search for firejump. The button below saves your choice.
The All-In-One-Gestures plugin for Firefox is a plugin that enables you to accomplish nearly every task you want to in Firefox with the help of drawing lines on the screen. You just need to assign the directions for the common task in the preferences and start drawing:
By default, the key for drawing gestures is the middle-mouse key, meaning the mouse-wheel, which can be changed however. The plugin is highly customizable as you will see on first glance when opening the options window, it is also updated regularly to be up-to-date with Firefox’ fast updates.
To show an example, as seen in the options table above, the following gesture will duplicate the current tab:
Gestures are shown as red lines on the screen by default so that you can see what you are drawing. Additionally, the tool can be misused to draw funny pictures on your Firefox windows!
Browser Cache (or Internet Cache) is there to speed up your browser performance by saving sites and items you visited on the internet on your hard disk and recalling them when you visit them again. However there may be times when you want to delete that cache because it either consumes too much disk space (its size can easily climb to 500MB and more) or you do not want someone who has access on your computer to see what sites you visited. In Firefox there is a simple solution for this. Click on the main button and open the Options window:
Select Advanced and go to the Network tab.
The Offline Storage section shows you how large your cache is at the moment. Here you can use the Clear Now button to delete your cache.
If you stayed loyal to Firefox 3.6, go to Edit > Preferences instead.
