It's still different in 16.02.

There shouldn't be any differences between Firefox 15 and 16

Can you attach a screenshot to illustrate what you want to change?

• http://en.wikipedia.org/wiki/Screenshot
• https://support.mozilla.org/kb/how-do-i-create-screenshot-my-problem

Use a compressed image type like PNG or JPG to save the screenshot.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do not click the Reset button on the Safe mode start window or otherwise make changes.

I don't have Firefox 15 and can't get a screenshot because of that =\ But it appears slightly smaller than in 15, and highlights letters in the URL when i type them in, which hurts my eyes a bit.

Are you referring to the auto-fill feature?

See "Prevent Firefox from automatically completing URLs":

• https://support.mozilla.org/kb/search-your-bookmarks-history-and-tabs-awesome-bar

You can set the browser.urlbar.formatting.enabled pref to false on the about:config page to disable the highlighting of the domain and see the full URL more clearly.

You can set the browser.urlbar.trimURLs pref to false on the about:config page to see the http: protocol on the location bar and in the pop-up if you hover a link.

No, i mean how the Awesome Bar organized sites by the number of times I visited them.

Do any of these threads help or do you still mean something else?

That's it! I don't know any CCS though.

Try to add this code to the userChrome.css file below the default @namespace line.

• http://kb.mozillazine.org/userChrome.css

The customization files userChrome.css (interface) and userContent.css (websites) are located in the chrome folder in the user profile folder.

• http://kb.mozillazine.org/Editing_configuration

You can use this button to go to the Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder

You need to create the chrome folder (lowercase) in the profile folder with the random name (xxxxxxxx.default) and place a file userChrome.css in it.
Make sure that you select "All files" and not "Text files" when you use Notepad or another editor to create and save the file.
Otherwise Windows may add a hidden .txt file extension and you end up with a not working userChrome.css.txt file.

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

.autocomplete-richlistitem { padding-top:2px!important; padding-bottom:2px !important; }
.autocomplete-richlistitem:not(:first-child) { border-top: 1px solid #ddd  !important; }
.autocomplete-richlistitem[selected="true"] { border-top-color:transparent !important; }

*|span.ac-emphasize-text {
 box-shadow: inset 0 0 1px 1px rgba(0,255,255,1)!important;
 background-color: rgba(0,255,255,0.2)!important;
}

Ok, let me see if that works!

It worked! ^^ it highlighted some text in light blue which i didn't like but i figured out how to get rid of it =3

You're welcome.

Yes, you can leave out that last bit or change it to this code if you want to disable the bold highlighting.

*|span.ac-emphasize-text {
 box-shadow: none !important;
}

Is there a way to change it back to the bold highlight like in firefox 15? In 16 it's a light gray box.
