Javascript in Firefox 90 PDF form viewer

more options

As of Firefox 90, the PDF viewer within Firefox is reported to handle Javascript in PDFs. What must be done to disable JAVASCRIPT within the PDF viewer?

被選擇的解決方法

Here's how:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste pdfjs.enableScripting and pause while the list is filtered

(3) Double-click the preference to switch the value from true to false

I'm not sure how to test that it worked. Maybe Adobe has a safe example on their website?

By the way, it was false up to Firefox 87 and flipped to true starting in Firefox 88.

I only see that pref set to true in Nightly.

Thanks for the info - It was Firefox 88 release notes where I saw the bit about JAVASCRIPT in PDFs. I wish I could change the title on this issue to say "Javascript in Firefox 88 PDF form viewer" - upgraded my test system to FF90 then upgraded 'production' to FF88. Usually my questions are associated with the test 'nightly' version. I overlooked it when nightly went to version 88.

有幫助嗎?
