  1. Is FontFinder extension multi-process (e10s) compatible (Firefox only question)?

    The old FontFinder extension is not e10s compatible and it will not be. However, my new implementation of this extension is e10s compatible. Give the new Font Finder extension a try.

  4. Can I access to the Fond Finder's features from a toolbar button?

    Yes, Font Finder installs a toolbar button on first run, however by default the button is not visible. If you want to add the button to the toolbar, simply right click on the toolbar and select "Customize ..." item. Find the button and drop it to the toolbar.

  5. How can I use Font Finder's analysis tool?

    To deploy the Font Finder analysis tool, click its icon on the taskbar. When it is activated, the icon's white background will change to orange to indicate its ready status. Once the analysis tool is hot, click an element of a page to see the font details, as shown below in the example for the headline.

    Any of these options can be quickly accessed through highlight & right-click, or through the use of toggling the icon in the statusbar (which makes it easy to analyze fonts before a :focus action occurs, such as input fields or links).

Editorial Review

If you are a designer, developer or professional typographer you may have been browsing the web at one point or another and wanted to know what a particular font on a webpage might be. Rather than having to seek out the information for yourself or take screenshots into photoshop or indesign it's now possible to have a full-featured tool for font analysis even in your browser and completely for free.

Font Finder is a tool that analyzes the font information of any font that you happen to find on a webpage. You can quickly access all of the analysis features by simply highlighting and right clicking an item or through the toolbar icon as well. The toolbar icon instantly analyzes fonts through an action focus pop-up window. This means you can receive alerts through input fields are links whenever you visit a new page.

Font analysis goes far beyond simply naming the font family. With detailed analysis from the application you can receive the RGB and hex code for the color, the background color, the family that the font comes from, the actual font size as well as information about the alignment. Details go even further to start naming element type, class, ID as well as some of the previous decoration, transformations, weights and variants on the font. This means that no matter what type of editing has been done to a font design you can replicate the same results with your own development as well as experiment with slight variations for your own needs. By copying font information to clipboard you can provide instant in-line replacements as well as test new font layouts for your websites and projects. Font finder really is the ultimate tool for designers and typographers. If you have ever thought about the fonts you see on your favorite webpages every day this is an easy way to replicate the style with minimal effort.
