FF 66.0.5 does not recognize userChrome.css

Posted

I use userChrome.css to accomplish two things - 1.) Put the tabs below the urlbar and bookmark toolbar. 2.) Get rid of the annoying search help dropdown that appears when I type a url in the address bar. But, after updating to FF 66.0.5 (Mac) my userChrome.css file does not work anymore. In fact, FF 66 didn't even have a Chrome folder.

Is this a deliberate move by the devs to kill userChrome.css? Or, have they changed how it's implemented and not telling anyone?

In any case, if anyone knows how to restore userChrome.css usability to FF66, I would be very grateful to learn how. Alternately, if there's any other way to get the tabs on bottom and eliminate the urlbar drop-down, I'd love to hear about it.

Firefox profiles do not come with a chrome folder, you need to create it yourself. For example, using the steps on my page here: https://www.userchrome.org/how-create-userchrome-css.html

What version of Firefox were you running before? The structure of the toolbar area changed in Firefox 65, so "tabs on bottom" rules from earlier versions no longer work. Since I can't test Mac tweaks, I suggest using the rules from Aris at: https://github.com/Aris-t2/CustomCSSforFx/

Regarding the autocomplete drop-down on the address bar, is this above and beyond turning off certain categories of suggestions (bookmarks, history, open tabs, search) -- you want to hide the entire thing completely? For that, the easiest way is to set its height to zero rows as follows:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.

(2) In the search box above the list, type or paste URLB and pause while the list is filtered

(3) Double-click the browser.urlbar.maxRichResults preference to display a dialog where you can change the value from 10 to 0 (that's a zero), then click OK
