I wish I could install this on the release version Firefox for Android, as I don't use the app. Is it only the beta in debug mode that saves the day? I tried debug mode in the release version but there is no custom addons option.

今やTwitterを使う際に必須です。
I want to turn off space notifications.

God bless the author of this extension.

This add-on is the only thing keeping twitter bearable these days! Huge props to the dev constantly and quickly adjusting to Elon's latest whims, you have the patience of a god.
