Protonmaill Read All Solution

protonmail_read_all_browser_script.js

/*
Protonmail does not allow to "mark all email as read". You can only do this page by page (50 at a time), but when you have thousands manualy going through each page is not possible. Here is my solution.

1. Open "All email" folder
2. Select "Unread"
3. Open browser developer tools (F12)
4. Paste this script.
5. If it does not work ask a friend developer to help you.

    return new Promise((resolve) => {
        //Find "Select all email" checkobx and click it
        document.querySelector('[data-testid="toolbar:select-all-checkbox"]').click()

        setTimeout(() => {
            //Find "Mark all as read" button and click it
            document.querySelector('[data-testid="toolbar:read"]').click()

            setTimeout(() => {
                //Find next button
                const next = document.querySelector('[data-testid="pagination-row:go-to-next-page"]');
