Форум сообщества Firefox для iOS

I recently bought a new computer and synced my Firefox profile. Bookmarks and other items have synced, but only two of my add-ons (extensions) are syncing from the old computer. I'd love to be able to sync them all especially because one of the add-ons is no longer available and I use it frequently. Is there a different way to bring the extensions form the old computer to the new one?

Thank you for your help.

The app is not logging in and keeps telling me to enter my password. This was after uninstalling and reinstalling the app. I can login on the browser, but the app must be bugged.

Two devices - MacBook Air and an iPhone. Both run the latest Firefox application, respectively. Starting with both applications having the bookmarks synchronised. Next, the bookmarks on one of the devices, say the laptop, are changed - some deleted, new added, overall bookmarks folders edited.

Question: How is it possible to ensure that Firefox synchronisation will transfer the latest compilation of bookmarks, as edited on the laptop, to the mobile phone application and not the other way round, undesireably restoring the preceding compilation, instead?

I use Firefox both on macOS and iOS. I have tried removing the application entirely from iOS, and yet old passwords are still appearing on iOS which I've deleted on desktop. I cannot for the life of me figure out why this would be an issue. I have disconnected syncs, signed out and back in, completely uninstalled the app.
