Firefox Tip: Find as you Type without Ctrl-F

I use the keyboard shortcut CTRL + F regularly to search for contents on the website that is open in Firefox or in a web sites source code if that is displayed instead.

It helps me find a particular topic of interest faster, especially if the website contains lots of contents or text which may make it difficult to do so without using the find feature.

Some webmasters still seem to think that putting as much content on one page is the way to go if you want to present your information.

While that is not necessarily bad, it is if you are looking for specific information and do not care about the rest. Find can also be helpful if you need to work on your own pages, for instance to correct spelling mistakes or find a phrase that you want to modify or rewrite.

Find as you type is a concept in Firefox that begins the search for the phrase when you start typing. This means that you do not have to press CTRL + F to open the search box in Firefox anymore, as you can start to type right away and Firefox will find all matching instances of what you type on the active web page.

Firefox will disable the feature automatically when you type in a web form, for instance when you leave a comment on a website or fill out a form.Defining Firefox's On-Page Find functionality

To enable this feature, you need to access the Firefox configuration.

1. Type about:config in the address bar and hit the enter key afterwards.
2. Confirm that you will be careful if the warning message pops up.
3. Filter for the string accessibility.typeaheadfind by entering it in the search at the top.
4. The default value is false for this entry. Set it to true to enable immediate searches on websites. You do so with a double-click on the preference.

There are several more options that can be configured. They require that accessibility.typeaheadfind is set to true. The first value is always the default one, unless otherwise noted.
