bug 1697191 removed several page action widgets. Some got changed into toolbar icons, like "Email link" or "Take a screenshot".

I think for the user to still easily discover functions, which have been added to address bar via page actions, once proton gets enabled, those "active" ones should be added to the toolbar for them. Users should not have to find e.g. the "Email link", which is prominent in the address bar for them before the update, on the "Customize screen" in between many inactive toolbar icons.

Also, are there any plans for actions like "Send tab to Device", "Copy link", "Share", etc. which don't seem to have a toolbar equivalent to add those buttons?

I think this is more toolbar or onboarding, on the address bar we don't handle persisting those anymore.

The Bugbug bot thinks this bug is a defect, but please change it back in case of error.

I hope this means that bug 1512851 can finally be implemented.

The File menu is a way better place for Share than a hidden menu somewhere. All other apps place share functionality there for a reason, it's a good standard that Firefox should follow.

Definitely missing the "Copy Link" button. I can right click on the URL bar to copy a URL, but it seems finicky on when it is selecting all text and then you have to change the text selection/keyboard focus back to the web page by making extra clicks.

Closing this as I think the train has left the station.

Andy, feel free to file a new ticket for a "Copy Link" button if there isn't one yet, but note that there also is an addon which does that now. I just quickly tested it: https://addons.mozilla.org/en-US/firefox/addon/copy-frame-or-page-url/
