Here I will publish results of (very) short tests of my tests for add-ons from Classic Add-ons Archive with SeaMonkey, until we will have found a better place.

  • 👎 Color Tab 0.2.3 [converted] by Wildsky  — I did not get it working with my SeaMonkey 2.53. Installation without problems, appears in Add-Ons-Manager, but does nothing (to be honest, I don’t know which effect can be expected from description ” … will let your boring new-tab page provide some beautiful color sets …”.
  • 👍 Ecosia 3.4.5  [converted] — The search engine that plants trees!  (by Ecosia development team)
    Installation of the converted add-on adds Ecosia to Search Sidebar Panel as currently active search engine. The results of a small sample look very similar to DuckDuckGo, but I read that the results are from bing. The search engine is really useful for me. Here you find some hints on Wikipedia.
  • 👎 YouTube2MP3 Converter has been working great for a while, but now the converter service page has become shut down for legal issues.
  • Go Parent Folder -signed1-signed (not from ca-archive!)
    👍 Worked for older SeaMonkey versions until 2.53 (beginning of 2019)
    👎 Does not work for latest unofficial SM 2.53
  • Link Checker 0.2d.1-signed.1-signed by ViJo
    currently I do not know whether that very old (2010!) add-on does work or does not.

  • 👍 I am using LinkChecker [converted] version by Kevin Freitas, which works fine. Unfortunately I do not know a source for it, the Web page is dead. May be you want to try download from

  • 👎 PDF Mage 1.0.3  (No Restart) by PDF Mage
    I did not get it working with my SeaMonkey 2.53, no button to start the PDF creation offered, also not when I tried to add one using context menu ‘customize’.

  • 👎 pdf creator 0.1.9
    Installation works fine after conversion, but I can’t find out how to use the add-on. I don’t find any new context menu entry, button or similar.
  • MeasureIt

    👍 MeasureIt 0.4.15 by Kevin Freitas: After conversion add-on installs and works fine with WIN SM2.53 (separate User Profile for tests). Creates a launch icon for the add-on in the SM Navigation Toolbar. After click on icon you can mark a rectangle on the screen, dimensions in px will appear. I haven’t a clue for what I should need that, but it works.

  • 👎 PDF Download
    Can not be used any longer with any browser, required infrastructure does no longer exist. hat become part of the Nitro Family.

  • R-Kiosk

    👍 R-kiosk by Kimmo Heinaaro
    After conversion add-on installs and works fine with WIN SM2.53 (separate User Profile for tests). After relaunch of SeaMonkey the browser will be in “Kiosk Mode”, no Menu Bar, no Navigation bar or similar is available. But it is not a perfect Kiosk, Sidebar is still active, so that Bookmarks, search and so on still can be used. May be you should disable Sidebar before relaunch?
    ⚠️ R-kiosk only can be disabled after SeaMonkey Browser has been launched in Safe mode.

  • Save as PDF Screenshot

    👍 Save as PDF 1.5.1-signed.1-signed by Pdfcrowd Team
    After conversion add-on installs and works fine with WIN SM2.53 (separate User Profile for tests). After relaunch of SeaMonkey the browser will show a Save as PDF — Icon at the right end of the navigation Toolbar. Works fine, PDF- results look very similar to source page, contain working hyperlinks, what makes those PDF documents much more useful that the output of printer solutions like FreePDF (my one might be outdated).
    But unfortunately there also are pages where the results of this add-on are completely unusable, for example Result here!

  • ❔ Show Parent Folder [converted] 2.1
    👍 Might work for older SeaMonkey versions
    👎 Does not work for latest unofficial SM 2.53

  • 👍 WebToPDF 12.11
    After conversion installation works fine. The add-on adds a new item to context menu for rightclick on web page contents with several sub items. I tested ‘Safe as PDF’, works fine. Result is only graphic, no text search, hyperlinks, … . For me that is not very useful. PDF export for this page see 190201_TestResultsForAddOnsFrom_ca-archive_ SeaMonkey InternetSuite! If such graphic export is all you need the tool offers a quick and simple solution.

  • 👍 Google Search by Image 0.3.1-signed.1-signed [converted] works fine. The add-on adds an Item to the context menu which appears when you click on an image on a web page. The search results differ a little from the ones Google Image Search does find, my tests were not intensive enough to tell whether there migt be an adventage for one of the add-ons. For the shown image i got this with Google Search by Image and this with Google Image Search.


For your own results please leave a comment including a link to a screenshot, I will move your results from Comment to this blogpost.

Classic Add-ons Archive

One possible solution for the “Many old type Firefox addons lost!” — problem (all FF-CLASSIC-addons dropped from AMO without having moved them to new repository) might be the:

Classic Add-ons Archive

After some trouble I managed to install it to SeaMonkey, but I doubt that it works. I observed 10 minutes of database provisioning …  without visible progress. I hope it will be possible to fix that.

I will keep you up to date here.


Many old type Firefox addons lost!

This blog post in German languagecompat1“Houston, we have had a problem” —  AMO Browsing for SeaMonkey and addon converter have become useless —  more or less 😡

For details see Bug 1517828 Firefox add-ons no longer available for SeaMonkey.

This means that lots of add-ons which where compatible with SeaMonkey after conversion no longer can be installed.

We will need the FF-addons without Webextensions successor versions on the new addon repository!
