docs: saveAs in iOS does not open in new tab as described

[bwhite94]

In the Readme it mentions:

Due to restrictions in iOS saveAs opens in a new window instead of downloading

But this is not the behavior seen in FileSaver.js version 2.0.5 and iOS 14.x. Instead the file is opened in the same tab, causing the user to potentially lose what they were doing before saving the file.

I have the same issue in Firefox 100.0.2
When downloading a file using
saveAs(xhr.response, fileName, saveAsOpts);
The current tab is replaced by the download. In Chromium it triggered file download in a deciated "download menu".

@bwhite94 have you found any solution to this?

@maciej-zabielski It looks like it is a Firefox bug as mentioned in #581 (comment). It should be fixed in Firefox 101.

Still seeing this behavior. Looking for a workaround. Happening in Safari.

@mylifeandcode I don't have the code right in front of me, but I believe I made the switch to manually open a new tab with the blob data URL. I can confirm for you on Monday.

Thanks @bwhite94 , that would be great. In the meantime, I'm looking at the code trying to figure that out for myself. I'm glad to know there is a way -- thanks!

@mylifeandcode the solution we ended up using was specific to jsPDF. jsPDF does utilize FileSaver, so I'm not sure if this will 100% work for you, but you may be able to look through jsPDF docs and source code for this function to confirm. Our solution with jsPDF is below.

const doc = new jsPdf({ somePropsHere });

window.open(doc.output('bloburl'), '_blank');

Thanks @bwhite94 ! In my case, it wouldn't be applicable, but I appreciate the info, and it's good to know about jsPDF. I hadn't heard of it, and may need it in the future. Thanks for going through all the effort to provide an answer, it is very much appreciated. :)
