A webpage cannot open a new tab automatically. Nicely done! Solves the problem well. However, you may want to use: iframe. Your current implementation will make the iframe invisible, but the iframe will still take up space at bottom of the page causing extra white space. It "semi" works for me. This is part of a larger mobile web app, and the fact that it gets canceled breaks the app because it raises a general web failure.
Any way around this? Nice snippet. However, setting a nonsensical things type is a bit disturbing. How do I force the download without a server? So just an html page with some javascript.

MarkAmery that works too as other answers have indicated. That approach AFAIK doesn't give you feedback on when the download starts, when it completed and if it errored which is handy. I could add that to the answer for a "fire and forget" option. Also the [download] attribute doesn't allow for a POST or anything exotic either. Your modern example is not quite right. It will "download" whatever the server returns. For ex, if you have an authentication error, it will return the login page or whatever the server returns and not the "downloaded file" itself.

For it to work on Firefox, do document. You can also do link. Show 3 more comments. Tomer 1, 13 13 silver badges 14 14 bronze badges. Chrome downloads, but Firefox just shows the picture. Saved me the time to test it only to find out it won't work.

Do you if this still works? Still works, but hit the same problem I was having with chrome downloads. Chrome is not ok with allowing extensions to download multiple files.

There's no need to simulate a click on a hidden a tag. Is this script in the content script or background script or somewhere else?
I am getting a "Uncaught TypeError: Cannot read property 'download' of undefined" on the line "chrome. BlobBuilder window. Kinlan Kinlan Where do I specify the file I am trying to download? That is up to you. It could be responseBlob on the xhr request — Kinlan. Yah, Can you edit the code to show how to do that? I have no idea where to put the location. A string representing the action you want taken if there is a filename conflict, as defined in the downloads. FilenameConflictAction type defaults to "uniquify" when it is not specified.
The cookie store ID of the contextual identity the download is associated with. If omitted, the default cookie store is used. Use requires the "cookies" API permission. A string representing a file path relative to the default downloads directory — this provides the location where you want the file to be saved, and what filename you want to use.
If omitted, this value will default to the filename already given to the download file, and a location immediately inside the downloads directory.
