[Steps to reproduce]:

1. Use RTL (ex. ar, he) build or de, fr, da localized builds. Open Firefox.
2. Go to in about:config to turn on the "Block autoplay" feature, set media.autoplay.default = 1 (block)
   media.autoplay.enabled.user-gestures-needed = true
   preferences.
3. Access some websites: https://edition.cnn.com/videos, https://www.arcticmonkeys.com/.
4. In address bar click on site information icon, at the bottom of this pop up at Permission section you will see "Autoplay sound" icon with "Block Audio" status button.
5. Click on settings gear button, then on "Settings..." button from Autoplay.

[Expected result]:
The "Allow Audio and Video" status button is right aligned.

[Actual result]:
At step 4 under the settings gear note the status button text and clicking on this the pop-up items are not translated.
At step 5 in Preferences "Autoplay" button and "Settings..." button are not translated.
Note that texts on this page are not translated into the desired language.

[Additional Information]:
Please observe the attached screenshot for more details.
This issue seems to be introduced when this feature "Block Autoplay" was introduced in nightly (Fx 69.0a1) and the issue is present in several localisations too (ex: ar, de, da, fr, gd, he). In es-ES and ko localisations are translated.

It looks like this string just hasn't been translated yet, see https://pontoon.mozilla.org/ar/firefox/browser/browser/preferences/permissions.ftl/?string=199780
