Where to find the JSView Firefox Addon – Discontinued from Addons Repo.

Update: Date: 6th Sept. 2014

From Firefox 32(Version 32) onwards, this add-on JSView has stopped working and is no more compatible and won’t be in future versions of Firefox as well. However there is an alternative add-on which can be used for getting the list of JS and CSS file being loaded with web pages. Its the “Phoenix” add-on. 🙂

Phoenix will tell you how many CSS and JS files are loaded into a page, how big these are, it will let you edit, pack and de-obfuscate them too.

Download the “Phoenix” add-on, the alternative for “JSView”. https://addons.mozilla.org/de/firefox/addon/phoenix/

Where can I find the popular JSView firefox addon which I have been using since a long time. Today I formatted my system and reinstalled firefox. JSView Suddenly I found that the the most useful firefox addon to list/view/copy path/url of JS files and CSS files is discontinued from the official firefox addon repository. On the mozdev.org site, its mentioned that ” JSView appears to have been abandoned by the author. It hasn’t been updated since July 2008 ”
However, we can still use this addon( of-course with personal choice/risk ) by taking it directly from the stored location as it is no more displayed on the addons/extensions list.

To install this addon on your firefox browser, open the link on firefox and follow the procedure.

    The plugin is no longer usable since version 32. I can confirm that …
    I think however this is an equivalent alternative:

      Hi SickSight, Even though this Addon is not listed on the Firefox addon server, but this old plugin still works on the latest Firefox version which I am using right now. It works fine for me !! However, the addon you have pointed out is good too. 🙂

    2. Subharanjan Avatar

      Yes, this addon is not working now. I was on FF31 and after upgrading to FF 32, this addon no more works. 🙁

  8. […] war es bis zum Update auf Firefox Version 32 funktionstüchtig und über verschiedene Quellen installierbar. Eben ein sehr hilfreiches Tool, was man gerne […]

    Hm, i can confirm what SickSight said. I can see a tooltip with counters for JS- and CSS-files, but no pull-down list of them, when i click the JSView-Button … bad 🙁
    Okey, so i will use phoenix instead …

    Phoenix plugin works fine, if not used together with Phoenix editor, which simply causes the browser to crash (tried several times, never worked).

    Hey there, thanks for the post. I was using JSView a lot, too bad it does not work anymore.
    Phoenix is okay but it misses a key feature: JSView extracted JS and CSS code from within HTML files and displayed it in an extra window. Phoenix however does only show external JS and CSS files plus whole HTML file. Do you know any details about why JSView does not work anymore? Maybe that is fixable or maybe the feature can be implemented into Phoenix?

      I am not sure why this addon was discontinued, but it seems like that the developer of this addon is no more active. 🙁

    Thanks bhai for the Phoenix, its awesome.

  15. Murray Avatar

    Well thank you for making this addon active for as long as you have. I know it was a life saver when I originally found your website last year.

    Thanks for the Phoenix tip. Lifesaver!

    I was missing the functionality that the JSView add-on provided since it stopped working with Firefox 32, so I developed a new one. ‘SpeedView’ has very similar functionality and UI to JSView and it works with the latest version of Firefox: https://addons.mozilla.org/en-US/firefox/addon/speedview/

      Nice to know about this new add-on. Thanks Dan !!

      Hey there, thank you for the new add-on, I use it a lot already.
      But unfortunately I think it is not working 100% accurate.
      The numbers of found files vary a lot between the JSView, Phoenix JS and SpeedView.
      JSView and Phoenix JS usually find around the same number of files, SpeedView somtimes finds a lot less.

      For example on this site JSView finds 31 JS/18 CSS, Phoenix 33 JS/18 CSS and SpeedView finds 18 JS/13 CSS.

      I am not entirely sure if this is a real bug, maybe the other addons just split the files differently.
      However, It would be great if every bit of code and css could be found and be displayed separately. I often use the addons to reverse engineer sites for bugfixing, so I pretty much depend on a complete overview.

    Thanks! I hadn’t been able to use JSView and finally decided to check it out. Phoenix is an excellent replacement. Excellent work!
