Every time I set up a new Firefox installation for someone, or myself, I spend the next 15-20 minutes trying to figure out how to change the tab focus settings to allow tab focusing for elements besides form input fields. For some reason, I never can get the correct Google search terms entered to find this. Anyway, if anyone wonders, here is what you do.
- type in the address about:config in the URL bar of Firefox. This isn't a valid url, but it resolves to the configuration settings for you browser.
- if your installation doesn't have a setting called accessibility.tabfocus, create one by right clicking and selecting "New" -> "Integer".
- set the value to the selection that fits your needs.
Possible settings
1 : Text field form controls only
2 : All form controls except text fields
3 : All form controls
4 : Hyperlinks and hyperlinked images
7 : All form controls and hyperlinks
