Firefox - Extensions

Using Firefox Extensions

Firefox logoFirefox provides a relatively simple set of features. You can add to these by downloading 'Extensions'.

Firefox, Security, and Extensions

When you download software, you're choosing to run that software on your computer - so firstly, make sure that it is *your* computer and not, say, your employers' computer.

You need to be confident that the authors of anything you download have good intentions, because if they don't have good intentions, your computer will no longer be yours. The essence of 'Firefox' is to provide you with what you need to browse the web safely, without getting in your way. Therefore:

When installing a Firefox extension, make sure that you are dealing with a reputable site, and if in doubt, you'll be more protected from maliciousness if you stick to extensions offered via Firefox's own 'Extensions manager'.

On a more positive note, 'Firefox' will not allow sites to install extensions without your agreement. Uninstalling an extension is simple - use the 'Extensions' menu will list installed ones and has an 'Uninstall'. (Though a malicious extension could protect itself by removing that feature)

Here's examples of extensions, you can find some of them using Firefox's 'Tools/Options' menu. If you find one of these via a web search, keep in mind the security risk involved.

IE Tab
Some web sites rely on specific features built into Internet Explorer, some are simply designed to be incompatible. This 'Firefox' extension allows you to easily open your current web page in IE using a context menu, and is useful if you're working with, say, Sharepoint.
'Find' toolbar tweaks
When browsing a web page and you need to search for a word, hit the '/' key and you'll see the 'Find' toolbar - just type the word and the page will scroll to the first instance of it.

The 'Find' toolbar lacks 'Previous', 'Next' buttons though - this extension gives you those, and you can also customise how long the 'Find' toolbar stays visible with a right mouse click.
Scrapbook
Gives you a sidebar into which you can casually drag web pages or highlighted text. Websites are stored as local copies, complete. Download it here
Dictionary Search
This adds a context or right mouse click item to Firefox, which allows you to select a word in a web page and run a search on it in an internet-based dictionary. Download it here.
Adblock Plus
Allows you to selectively block advertising on web pages. Download it here.
Sage
Sage allows you to use RSS feeds in the sidebar - information rich sites may provide RSS feeds as a way to provide a preçis of the information they hold. Download it here.
Copy URL
Allows you to copy the page URL to the clipboard along with a snippet of text from a web page. Useful when storing/forwarding references to pages in an email, and also useful when working with 'Zoot'. Download it here.
Weave
Once you've installed Weave and created an account, your bookmarks and settings can follow you around when you use Firefox from various machines. Note that this may involve any web site login details and passwords being encrypted and sent via the Internet to Mozilla's servers. Here's more on Weave, from the authors.

Firefox: its Preference Settings, and some Rocket Science

You can influence 'Firefox' using its 'Options' (or preferences) menu. When you need more preferences, open a page and type about:config (with no spaces) in the address bar. This displays a page of configuration settings: you can edit a setting by double clicking it. You might need to search the web to find the correct options for these but here's an example

Control animated gifs, stop animation or make it loop once
Look for the setting image.animation_mode. It has three values 'none', 'once' and 'normal'. Set your preference and it will be applied to all animations. Frenetic pages will become docile.
NTLM authentication
Allows you to be automatically logged into web sites such as the applications server, here's more info on NTLM authentication.
