FeatureFix

[changelog]

The FeatureFix extension fixes some Firefox interface issues - such as adding support for popup ALT attributes - as well as adding some handy features for developers. It offers quick access to some of Firefox's hidden preferences, and a few toolbar buttons that may be helpful in exposing extra functionality. Please feel free to contact me if you have any bug reports or suggestions for improvements to FeatureFix.

You can download/install FeatureFix from the Mozilla add-ons site.

If you wish to show your appreciation, please help out by clicking the 'Flattr' button at the top of the screen. :-)

Some of the major features of FeatureFix are covered below.

Popup ALT attributes

By default, Firefox's behaviour is to popup the TITLE attribute of an image, but not the ALT attribute. Although this is reasonable behaviour, it can be helpful to be able to see the ALT attribute of an image because historically it's been used to convey extra caption information that's not otherwise available. There are still some major sites that do this. FeatureFix allows you to configure Firefox not just to popup ALT attributes for images, but a whole host of attributes for any element on the page. This can also be useful for quick debugging purposes.

Customize source viewer

Firefox has long supported the ability for users to customize their source viewer, rather than using the internal source viewer. However, this functionality is not very visible and is only accessible using preferences. FeatureFix offers a source viewer customization dialog and a 'View source' toolbar button for convenience.

Work offline

Firefox supports a 'work offline' feature which will prevent it from connecting to the internet to refresh its cache of a webpage. FeatureFix offers a toolbar button to make this functionality quickly and easily accessible.

Many minor tweaks

The main FeatureFix configuration dialog has many tweaks for developers and power users who may wish to customize various behaviours of Firefox and parts of its interface. Often these features would be hidden in the 'about:config' section of Firefox. In some cases, they are implemented by FeatureFix itself as no config setting for the tweak exists.
