That’s what malicious code is primarily aimed at!įor further details please contact your preferred malware developer.Ĭonclusion: The answer is still valid … do your homework first à la improving your reading skills, and second do a proper research before spreading your * again. JavaScript for Acrobat APIs is not only a bit different compared to Browser support for JavaScript APIsīut also can handle a bunch of other things.

Also, you may feel more comfortable knowing that if the PDF contains JavaScript for an Adobe application (or any other PDFviewer/editor), that is disregarded by the pdf.js viewer.†There is a possibility that a PDF could be crafted to trigger some kind of vulnerability in that conversion code, but it would have to be a different kind of attack from ones affecting native applications like Adobe Reader/Acrobat or Apple Preview. €œFirefox’s internal PDF viewer (based on pdf.js) converts the PDF to HTML. Until Firefox 87 the pdfjs.enableScriptingconfig option was set to false you could set it to true … the default since Firefox 88 >”MORE THAN 1 YEAR AGO on 4/30/20, obviously when pdf.js in FF didn’t even support JavaScript in PDFs”
Second, I’m not writing a thesis here, so a precise citation of sources is not mandatory. But you can’t wait for such news, can you? That’s how we found out who “generates the clever of you Emil to omit where you copied this text from.”įirst, the text is clearly marked as a quotation by citation marks. When the news comes that, for example, the new version of Firefox has disabled by default all telemetry and it can not be enabled remotely – almost everyone in the comments will rejoice. Suddenly (sarcasm), it is possible to make changes in a browser that will please browser’s users.Īnd when the news about the changes in FF looks like this: removed this, disabled this, removed the ability to configure this, and only the collection of telemetry becomes more, then there will be “haters” of such changes. The market share of Firefox is dropping, while, for example, the market shares of Vivaldi and Brave are growing. And this is directly related to the number of browser users. Because the amount of money they have for development directly depends on how much they earn through affiliate programs with search engines, etc. There will be no one left to “hate” the browser.Īnd pray that Mozilla will have enough money to continue development. And users will only leave the browser more.ĭon’t worry: at some point there will be no haters left, and at that point you will suddenly realize that the browser has almost no users left: it will be like some Chopera with about 1% marketshare. Most Firefox users may not need the feature, and it is a good idea to disable the execution of JavaScript in PDF documents in the browser to protect the system against JavaScript-based the “haters” for all firefox’s problems only makes firefox situation worse. In other words: JavaScript is a security risk when it is executed in PDF documents. Unfortunately, JavaScript in PDFs may also be used to execute malicious code. There are legitimate reasons for supporting JavaScript in PDF documents, for instance to verify the input in form fields or to make changes to a document based on data when it is opened or when certain events happen.
Mozilla enabled the execution of JavaScript in PDF documents in Firefox 88 this means that JavaScript code will be executed if it is present in a PDF file that is viewed in Firefox. The execution displayed the JavaScript document in the browser but ignored any JavaScript code that it contained. Up until now, JavaScript was ignored by Firefox when PDF documents were viewed in the browser.
