The Firefox web browser comes with the ability to zoom in and out of websites. There is however no way of zooming only specific elements of a website which can be a problem if only specific elements such as images need to be zoomed. The Firefox and Thunderbird extension Image Zoom adds that feature to the zooming functionality by providing the means to zoom in and out of images in the programs.

Image Zoom has been designed with simplicity in mind. A right-click on any image on a website will open a context menu after installation of the extension with options to zoom in and out of the selected image. Many options are displayed here then, from selecting preset values to configuring custom zoom and dimensions, to zooming in and out gradually.

Right-clicking and using the context menu is however not the only option to zoom images. Another possibility is to right-click and using the mouse wheel to zoom an image. That's usually more comfortable than the context menu solution. Other options that are provided include page zooming, fitting an image to the screen size of the web browser or email client and custom zoom and dimension options.

Some add-ons can interfere with some of the options provided by the Image Zoom extension. Especially add-ons that make use of the mouse buttons, like the recently reviewed Multi Links add-on, can block some of the functions. Image Zoom offers some options to configure the mouse buttons that trigger the zooming. It can be downloaded from the Thunderbird or Firefox website.

If you sometimes need to zoom in or out of images in Thunderbird or Firefox, then this is the add-on that you may want to try out first to see if it matches all of your requirements.

      Paulus yes that is it. The Thunderbird add-on can also be installed in Firefox. I add a link for Firefox as well to avoid the confusion.
