Want to make your misspelled words stand out a ‘bit more when composing a message in Firefox? It is easy to do with this quick about:config tweak. You can select no highlighting, a dotted line, long dots, a single straight line, a double underline or the default squiggly line.
Here is how you can make your spelling mistakes stand out more in Firefox.
- Enter About:config in the Firefox address bar. If it pops up an alert, tell it that you know what you’re doing and proceed.
- Search for ui.SpellCheckerUnderlineStyle. If you find anything, skip to step 5.
- If your system is like mine, you found nothing. That means you have to add this configuration value. Right-click the main portion of the window and select New > Integer.
- Now, enter ui.SpellCheckerUnderlineStyle to create a setting by this name.
- Now you can set the value of this setting to one of several options: 0 for no highlighting, 1 for a dotted line, 2 for long dots, 3 for a single straight line, 4 for a double underline (like you see above – that’s my pick), and 5 for a squiggly line, which is the default.
Once you are done, you will be able to spell check like no other! Well, ok – that might be a little dramatic, but you will have a more customized misspelled word notification.
