Resource blob not found on IE11

[ofirdev]

I'm getting several errors with the attached pdf in IE11:
Resource 'blob:F2053AEF-3AE5-42E4-A411-D6F6E95E7072' not found

The loading icon on the second page keep spinning.

In a custom viewer with paging buttons, I can't switch from the first to the second page.

Probably some intermittent problem with IE11 in non-debug mode. I can see images when debugging the PDF.js.

Report it to the vendor via https://connect.microsoft.com/

As a workaround you can modify PDFJS.createObjectURL to always create data URL instead https://github.com/mozilla/pdf.js/blob/master/src/shared/util.js#L1103

I can also see the images on both pages but page 2 loading spinner keeps spinning on IE11.
Maybe the blob issue is not the cause.

Maybe the blob issue is not the cause.

I'm confused about this statement. The error clearly points to an issue with blob.

I meant that the page displays fine even when I see the error.
Something makes the page stay in loading state.
For me, it's not an intermittent problem and it happens every time.

Something makes the page stay in loading state.

Yes, it's waiting for image to be loaded. We probably shall add img.onerror stuff when img.onload is used

[ofirdev]

Is there a workaround for this iissue n IE?
I understand that it's a browser bug but it makes pdf.js unusable for us on IE.

@ofirdev Yury posted a workaround a few comments ago:

"As a workaround you can modify PDFJS.createObjectURL to always create data URL instead https://github.com/mozilla/pdf.js/blob/master/src/shared/util.js#L1103"

[ofirdev]

I've tried commenting lines 1182-1187 to force it to use the data schema but I'm getting the same error.
https://github.com/mozilla/pdf.js/blob/master/src/shared/util.js#L1182
Can you explain how I can use data URL?

After all the work invested in IE compatibility, why are you willing to drop support instead of adding a simple fix in the compatibility.js file?

[timvandermeij]

@ofirdev We are not dropping support for IE, it's just that the developers are also very busy with other parts of PDF.js. There aren't that many developers and because it is primarily being developed for Firefox, the focus is there. We are definitely trying to support as much browsers as possible. Pull requests are therefore very welcome!

Let's see if Yury has more ideas.

@ofirdev did you report the issue to the IE vendor?

[timvandermeij]

@ofirdev Yury made #4103 to address this issue.
