Hi,

Try to add the following code snippet to the Custom CSS area in Theme Settings to fix the firefox mobile search issue.

.mobile-nav .search-results-wrapper .woodmart-scroll { overflow-y: auto; }

The URL encoding does not depend on our theme but depends on the browser itself. For example, it can be seen on the Wikipedia pages: Chrome https://gyazo.com/bb0a63fe824fb929809ef6daa3a532d6, Firefox https://gyazo.com/141f45470a861666cf1c58d2a530169f.

Regards
