• (2023-08-21) Helmut Karlowski: Works as expected.
• (2021-09-16) Mark Good: I couldn't not get it to match on any filter expression. Tested my regex and it was valid. It just refused to change the content type. 🤷‍♂️
• (2021-04-03) Syamsuwar Andi Matto: Very useful Kudos!
• (2020-10-06) Wiley Sanders: For experts only, minimal documentation. Would be more useful if it had a feature to snoop headers and inform you of a download's mime type.
• (2020-07-08) Kyle Balling: This does not seem to modify content type when the content is displayed in an <embed> tag generated on the fly.
• (2020-02-02) miva YS: It works! >>> URL Filter: .* Original Type: application/octet-stream.*; name=".*\.pdf" Replacement Type: application/pdf Disposition: inline >>>
• (2019-10-14) Michael Stephenson: Any example how to use it? https://sd-app-01:8443/assystnet/attachments/Attachment?linkedObjectId=11587969&linkedObjectTypeId=46&attachmentId=1607746&attachmentDate=1570695459307 How convert it to png?
• (2019-06-29) Richard Yang: Only extension available that was able to render a PDF in browser. All I had to do was change octet-stream to pdf (mime-type) and attachment to inline.
• (2019-02-19) aparna shilpa: Extension works great but it is no longer supported by latest version of Chrome Browser (72). Any tips on getting this working ?
• (2019-02-18) John Chen: not work in 72.0.3626.109
• (2018-08-05) Martin Hering: It works for PDFs for me. Using the following settings: URL Filter: .* Original Type: application/.*pdf Replacement Type: application/pdf Disposition: inline
• (2018-02-02) Rohit R: Please provide instruction on how to use it. What rule to be added to open all png images in browser itself (for all websites i visit). Currently when i click on a png, its downloading the image..
• (2017-06-07) István Ujj-Mészáros: Works like a charm (not when opening a file directly, but works through a web server). I am using it to view txt files as HTML.
• (2016-09-15) Alessandro Meroni: very useful for filter larger xml files to be opened from chrome!!
• (2016-06-21) Mike Crews: This is perfect for fixing over-engineered web applications like JIRA and Confluence that force your browser to download content that could easily be displayed inline.
• (2016-04-11) doesnt work at all
• (2015-10-28) Vijay Srivastava: You can use this to render git row file, which normally comes with text out put.
• (2015-05-04) Brad Stronger: I added a simple rule to change all image/png to Disposition: inline. No more stupid image downloads!
• (2015-02-11) Dex Luther: Kinda sad I have to download an add-on to do something the browser should be able to do on it's own. Thanks for making this available to correct yet another one of Chrome's pitfalls. The instructions could be a lot better to make this a lot easier to use.
• (2015-01-21) Rohit N.: Awesome, works great, you need to know regex though but the instructions are great!
• (2015-01-08) George Averill: Lets me view textual files that the browser normally tries to download. Thanks!
• (2014-06-25) Daniel Raj Norman Vaseehar: how to use this tool to change the content type
• (2014-06-05) Maryann Frank: i loved it because we are so fast of typeing
• (2014-03-08) Juan Rodriguez (Juani): Do what it says. Easy to use.
• (2013-12-13) Justinas Bedzinskas: Very useful extension which we are using in our project! 5 stars.
• (2013-12-02) Jay Q: Very useful extension! Specifically addresses Chrome's inability to figure out that if Content-Type contains, e.g., "image/png" in the string, it's a safe bet it's a PNG and is fine to display in its own browser window if you so choose (Chrome can't understand "image/png;charset=UTF-8") :-\. Would give 5 stars if instructions were clearer.
