Hi,

I am using an iframe to render a PDF file on firefox. The file gets downloaded in C:\Users\xxx\AppData\Local\Temp folder and the downloaded file is opened by the PDF reader and is not visible inside the browser window.

Is there any way to restrict the file from being opened by PDF reader and to show it in the browser window itself (the way its is displayed on chrome browser) ?

I am using below code to render in browser: <iframe style="margin-top:10px;" src="' + ArtifactfilePath + '#toolbar=0" width="100%" height="100%" id="iFramePdf" #zoom="200" frameborder="1"></iframe>

ArtifactfilePath is the filepath.

That is not possible, only when the builtin Firefox PDF Viewer is used then the file won't be downloaded to the temp folder (but will still be downloaded and stored in the cache). Files that are passed to an external application are always saved to the temp folder.

Firefox opens a PDF file in a tab only if the server sends this file as application/pdf. Any other type or a generic type will Firefox show the download (open with) dialog.
