HTML Form to open links no longer working

[ipodhacks142]

Previously I have used a form with links in to create a drop down menu that users can choose a file from to download. This has been working fine up until recently when it suddenly stopped working for no apparent reason. I beleive this to be caused by something being changed with wordpress. See code below:

<form style="clear: both; line-height: 25px; height: 25px; vertical-align: top; margin-bottom: 15px;" onsubmit="open(this.url.value,'','');return false;">
<div style="float: left; display: inline; margin-right: 5px; width: 300px; line-line-height: 25px; height: 25px;"><select style="width: 300px; padding: 1px;" name="url"><option value="">Download iPhone firmwares</option>

        <option value="">&#8211; &#8211; &#8211; &#8211; &#8211; &#8211; &#8211; &#8211; &#8211; &#8211; &#8211; &#8211;iPhone X &#8211; &#8211; &#8211; &#8211; &#8211; &#8211; &#8211; &#8211; &#8211; &#8211; &#8211; &#8211; &#8211;</option>

</select></div>
<div style="float: left; display: inline; line-height: 25px; height: 25px;"><input type="submit" value="Download" /></div>
</form>

Previously, upon clicking the download button, the link would open immediately in a new tab. Now though, a link similar to the one below opens in the same tab (the link in the menu is just added onto the current page URL).

I fairly sure this is an issue with wordpress itself as nothing else has been changed. If you need any other information please let me know. I really need this solved as soon as possible so any help would be appriciated.

Also worth mentioning that this code has always been broken by wordpress if you open the visual view, but it works if you only open the page in text view.
