Imports Steam Wishlist to SteamDB Watchlist, albeit very slowly. Instructions below.
Copy the following code into a text editor and save as an html
<!doctype html>
<html>
<head>
<title>Open Windows</title>
<script>
function openWindow(){
var x = document.getElementById('a').value.split('\n');
atTime = 0;
for (var i = 0; i < x.length; i++) {
if (x[i].indexOf('.') > 0) {
site = x[i];
if (x[i].indexOf('://') < 0) { site = 'https://' + x[i]; }
setTimeout("window.open('" + site + "')", atTime);
atTime += 20000;
}
}
}
</script>

Using the Augmented Steam extension, export your wishlist as text type with the following text format:
https://steamdb.info/app/%appid%
Click copy to clipboard.
Open and paste links in the text box from the previously created html file, click the Open Window button, and let the magic begin.
If your browser warns or blocks any pop-ups created by the local html file, enable/allow them, or this will not work.
To change the delay time to open links, edit the line in the html code:
atTime += 20000;
