Firefox Central Tips & Tricks This page contains various tips and tricks for Firefox. Most of these tip s involve editing of text files on your hard drive and is not recommende d if you're not familiar with basic file and folder usage. The tips are divided into four categories and sorted by importance/popularity.
The image can be of any image format supported by Firefox. Make the active tab easier to distinguish In order to make the active tab easier to distinguish among the currently opened tabs, you can also change the colors for the tabs.
The full path to this folder could be C:\Program Files\Mozilla Firefox\chrome\icons\default\. xpm files) and then place it in this folder and rename it to main-window.
Back to Top Browser Behavior Open external links in new windows or tabs If another program wants to display a web page in the default browser, Firefox will reuse an existing window by default, which means that it will navigate from a page you might be reading. under Linux and Mac OS X), select Advanced and click on Tabbed Browsing. Under "Open links from other applications in:", you can choose the alternative you prefer. Reveal More Tab/Window Options There are some hidden options for the Tabbed Browsing that will allow you to force links that open new windows to open in the current or a new tab.
under Linux and Mac OS X), select Advanced and click on Tabbed Browsing. The following options should be visible: Force links that open new windows to open in: the same tab/window as the link a new tab The options should be self-explanatory.
tip above, you learned how to reveal the Force links that open new windows... If you activated this, all windows that a web page wants to open will be diverted to either the current tab/window or a new tab.
Use error pages instead of dialog messages By default, Firefox displays annoying error messages if a connection fails, instead of quietly displaying the error information in the browser window as Internet Explorer does.
Note that this feature is still a bit buggy as it removes the last visited page from the Back button history. Tweak Find As You Type Find As You Type has a few hidden preferences that can be changed to better fit your needs.
Disable Other JavaScript Window Features Firefox has a few options that allow you to decide what scripts can and can not do with windows. These options are available from Tools > Options > Web Features > Advanced.
This tip can also be used on dual-boot systems to use the same bookmarks on both operating systems. Just make sure that you place the file on a location that you have write access to from operating systems. Change the search mode in the address field By default, if you enter a search term in the address field and press Enter, a Google "I'm Feeling Lucky" search is performed, and you're taken to the first result of that search directly.
Prevent URLs from being saved in Location Bar Firefox allows you to prevent URLs from being saved in the pull-down menu for the Location Bar. This restriction helps protect user privacy and prevent users from "stumbling" into sites that other users had previously viewed. Andrew Mutch has written a page explaining how to implement this restriction.
Prevent sites from disabling the context menu Some sites prevent you from right-clicking on the page to show the context menu. This bookmarklet will disable such attempts with just a single click.
Back to Top Web Page Appearance Ad Blocking Advertisements on websites are annoying, often breaking up text and flashing to get your attention. There is a neat trick that you can use to block most of the ads on Web pages.
Note that this will also make the frames appear with a fixed-width border and thus, may make the pages look funny. Change the cursor for links that open in new window This neat trick will change the mouse pointer when you hover it over links that will open a new window.
Back to Top Other Tips Change language on web pages Some web sites offer content in multiple languages. You can choose several languages in Firefox and they will be treated in order of priority. Run Firefox from removable media This advanced tip makes it possible to run Firefox from removable media, such as a USB memory stick. This will allow you to run Firefox with your personal settings from any computer, even those that don't have Firefox installed.
In this example we will use R:\Firefox for the application folder and R:\FFProfile as the profile folder, assuming the drive letter for the removable media is R:. The reason why a batch file is needed instead of a simple shortcut is that a shortcut uses absolute paths, and since the actual drive letter for the removable media may change depending on which computer it is plugged into, the relative path used in the batch file is guaranteed to work anywhere. Select and copy individual table cells While holding down the Ctrl key, you can select table cells. You can select multiple cells, either by clicking individually on the cells you want to select or by just dragging with the mouse. Once selected, you can use Copy and Paste just like you would on a text selection. Speed up page rendering By default, Firefox doesn't try to render a web page for 250 milliseconds while it's waiting for data.
js file, Firefox immediately starts to display the page, even without complete data. The drawback, especially on slower machines, is that the total time to display the page will be longer. Enable Pipelining Pipelining is an experimental feature, designed to improve page-load performance, that is unfortunately not well supported by some web servers and proxies.
Remember to use two backslashes for the path separators if you're using Windows, eg "C:\\Path\\Path To Cache" instead of "C:\Path\Path To Cache". Specify the memory cache usage Normally, Firefox determines the memory cache usage dynamically based on the amount of available memory.
Limit Firefox to specific web addresses Many libraries are now providing web-based online catalogs and access to online databases. Often, libraries don't want computers provided for those uses to have access to the entire Internet. This method will assist you in limiting Firefox access to a pre-defined number of sites. Restricting web access is accomplished by using the proxy settings in Firefox.
