Why my browser is unable to download files with Rselenium?
<p>For some reason, I can't download any file using my <code>Rselenium</code> and <code>Firefox</code> web driver. In short, I'm unable to save the file, the option is greyed out.
I'm using this as a profile:</p>

<pre><code>fprof &lt;- makeFirefoxProfile(list(
  browser.download.dir = d_pth,
  browser.download.folderList = 2L,
  browser.download.manager.showWhenStarting = FALSE,
  browser.helperApps.alwaysAsk.force = FALSE,
  browser.helperApps.neverAsk.saveToDisk = "text/comma-separated-values, text/csv, application/csv, application/excel, application/vnd.ms-excel, application/vnd.msexcel, text/anytext"))
</code></pre>

<p>This is what I get in all the cases, greyed out...</p>
