I need help to add an additional parameter of a password or secret key to our Firebase database. This will change the stock google signup methodology, which will then be served to our backend to get a ubiquity JWT token from our backend API. We skipped the question of what platform to use to host the Firebase database, and decided to go with JavaScript for the programming language for making the changes. Finally, we have chosen to store the additional parameters in plain text, rather than encrypted. We are looking for someone who can help us make these changes to the Firebase database using JavaScript and make sure that the additional parameters are securely stored in plain text. If you have experience doing work like this, please let us know how you can help!

Please read carefully and don't make an offer if you can't do exactly what I need. I need a solution to open (popup) window on second screen/monitor in full screen mode. So, on first screen/monitor (main screen) is opened browser (web page) with button on it. When that button is pressed/clicked, new (popup) window should be opened on second screen/monitor in full screen mode (like that F11 is pressed on that new window). So, it is not an option to open popup window and drag and drop it to second screen/monitor, or to click buttons on that new window to go full screen or something else. In the attacment, there is an example - left side is main screen with button, and on the right side (pink one) there is second screen/monitor when button is clicked.

I have a web page (attached) that opens modal popups for audios, videos, and multiple levels of text. Clicking ESCAPE calls a function that closes one popup (just one level). If there are more than two popups open, it closes the top one. REQUEST: I want the browser back button to do the same thing as clicking "Escape". In other words, I want the browser back button to have the effect of closing one popup. HOWEVER: If there are no popups open, then clicking the back button should take user away from the page. Therefore, using a method won't work here. Such a solution would lose all modal/popup levels anyway. I believe the solution needs some combination of pushState, popState, replaceState, and/or perhaps something I'm not aware of. *This is a request for JavaScript...
