In Bug 1676137 I'm planning to remove the intl.uidirection pref. This pref was introduced in Bug 1312049 to make it easier to test right-to-left (RTL) locales, but since that time, pseudolocale support has been added to Firefox.
For testing purposes, setting the intl.l10n.pseudo preference to "bidi" is preferable. It switches the text direction to RTL, but it also decorates the text, making it easier to notice unlocalized text. In Bug 1673054 I consolidated existing test code to use the "bidi" pseudolocale, and in Bug 1675789 I improved the readability of the "bidi" text based upon developer feedback. Removing the intl.uidirection pref would allow us to continue to consolidate and clean up the localization code. We have had feedback that some users use this pref to force left-to-right layout while using a locale that is normally RTL, but this was never the intended or supported use case for this preference. The proper way of handling this would be to define a locale variant to support this and submit it to the Unicode Common Locale Data Repository.
