2024-08-06 Ryuno-Ki Although I used to use this add-on for a very long time I am disappointed to find it is now offering a "service" to ChatGPT without informing me about changed terms of services or similar. I'm unsure whether this is even allowed under the current license. Find the new repo at https://github.com/OpenLinkSoftware/OSDS_extension

2022-07-05 Lorenzo Gabriele Really great extension for people who want to optimize their websites for search engines. It lets you see what data your competition has that you miss so you can fill the gaps. Really appreciated! Keep on the good work!

2017-03-08 selligz I became a fan at first use but it stopped working! Tried to update - no success (I have FF 52.04 64 bits + OSDS 2.13.9). Really hope it'll wake up... EDIT: now, with FF 53.0.3, OSDS 2.14.5 works perfectly again… :-) EDIT2 (nov 2018): Now I notice that FF Quantum correctly takes into account XSL style sheet when displaying XML documents ONLY IF OSDS is NOT active. With OSDS active, the XML tree is shown without XSL style rendering (try http://gja.frndz.pagesperso-orange.fr/technik/xsl_tuto/monXML.xml - an example in my page on XML/XSL/PHP transform). Is there any setting to avoid this while keeping OSDS active?
2017-01-30 kidehen Provides a powerful addition to Firefox that reveals the otherwise hidden benefits offered by a Semantic Web. For instance, I can see how Microdata, RDFa, JSON-LD, RDF-Turtle, and POSH amount to a variety of notations for embedding structured data in pages which make them easier to understand by modern agents (browsers, crawlers, smart agents).
