Disable percent-encoding
Problem: URL copied from address bar is percent-encoded, so if URL contains non-latin symbols (for example, cyrillic) it is unreadable for humans.

Possible pitfalls: Non-latin letter symbols is not supported by standard for http(s) URLs, but virtually fine for all modern browsers. Space symbol (%20) stay percent-encoding, so copied URL don’t “breaks”.

Special URLs
Firefox include a few dozen special URLs that can be helpful in determining more information about various Firefox settings. These URLs can be entered into the Super Bar to view the special pages. A few of the more significant ones include:
