Manifest v3 removes PageActions

[madiso]

Besides the content blocker controversy, I just remembered another thing - Manifest v3 removes PageAction support from extensions.

For those unaware, this is the difference:

BrowserAction:

• Normal toolbar button
• Button is always visible
• Supports badges like number count

PageAction

• Appears on address bar in Vivaldi (and Firefox; on Chrome it just displays a blue dot when active and gray otherwise)
• Button is visible when needed
• No badge support

In other words, an extension like AutoPagerize or CRX Viewer must then always display a button, even if it cannot do anything on the page.
For Chrome, that's irrelevant, as it has forced to make all extensions appear as a button, even those that don't "do" anything when clicked.

But what about Vivaldi? Shall we now get an extension store and support WebExtensions?
