Firefox to become first mobile browser to support desktop extensions later this year
(blog.mozilla.org)
This is a most excellent place for technology news and articles.
safari has been able to do this for years
~~Vivaldi~~ I meant Kiwi (chromium) also uses the regular chrome web store.

Firefox mobile used to have mobile add-ons but it was separate and naturally therefore more limited.
