It appears from my research that being able to add Chromium (Chrome) extensions to Falkon depends on QtWebEngine adding this functionality, which it currently does not have. Here is a link to a QtWebEngine request which received this reply dated 19 Mar 2019: "Tentatively considered for Qt 5.14." https://bugreports.qt.io/browse/QTBUG-61676 Hopefully we will get this capability eventually. 1847668 3 yo 2019-03-31 04:41:56 +0000 Does this involve making a basic layer for building extensions or going as far as adding extension support as outlined by Mozilla?[1] One could just go for the one outlined by the W3C community group[2] [1]: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions [2]: https://browserext.github.io/browserext/ 1956875 4 web 2020-09-12 03:55:24 +0000 it would be great +1 any news? 1980309 5 cfeck 2020-12-01 12:54:17 +0000 *** Bug 428832 has been marked as a duplicate of this bug. *** 2043769 6 yamiyukisenpai 2021-06-27 06:10:31 +0000 Any updates about this? 2111038 7 yamiyukisenpai 2022-03-13 23:05:14 +0000 Updates? 2175521 8 rleyvasal 2022-11-20 22:42:43 +0000 It would be great to have the extensions from Chrome and Firefox work in Falkon - I would speed up the development and adoption of Falkon 2175523 9 rleyvasal 2022-11-20 22:46:01 +0000 Having Chrome and Firefox extensions work in Falkon would help speed up development and adoption of Falkon browser. 2346505 10 jurajoravec 2024-08-18 17:52:02 +0000 *** Bug 491653 has been marked as a duplicate of this bug. *** 2478728 11 fourstringsplayer 2025-12-22 14:36:20 +0000 I successfully implemented Chome extensions support for Falkon. I am just waiting my KDE Identity to be approved so I can push my git branch to https://invent.kde.org/network/falkon What made the extension support possible was the new class QWebEngineExtensionManager introduced in Qt 6.10 I just created a new tab in Preferences dialog, with a button to add a local extension file, and a button to remove a selected extension. All my modifications have conditional compiling and are only compiled in systems that have Qt 6.10+ The Google Chome Web Store blocks Falkon to download the extensions directly from there, because Falkon TLS fingerprint doesn't match with Google browser family (Chrome, Chromium) even using QtWebEngine which uses Chromium. I post a new comment here when I push it to KDE Invent. 2478764 12 web 2025-12-22 17:12:31 +0000 It would be great, if true. 2478766 13 nate 2025-12-22 17:14:33 +0000 Nice, that sounds cool! 2478809 14 fourstringsplayer 2025-12-22 19:53:50 +0000 My work is ready to be reviewed at https://invent.kde.org/danielvarella/falkon Remember that this feature only compiles with Qt 6.10+ I need your feedback. Tell me what can be improved. It supports Chrome extensions to be installed only using a local file for now. Installing and updating Chrome-like extensions will only be possible if they are hosted in a website, for example store.falkon.org I volunteer to implement the client-side. 2482042 15 nate 2026-01-05 18:10:32 +0000 Falkon developers will have the highest chance of seeing your work if you submit it as a merge request. Can you do that? Thanks a lot! 2482061 16 fourstringsplayer 2026-01-05 19:32:35 +0000 I have some bad news... I implemented everything needed for extensions support, but there is something missing from the Qt side. I filled a bug, but I don't know how long they will take to fix it. More details in https://qt-project.atlassian.net/browse/QTBUG-143169 Should I submit a new merge request when this problem is resolved? 2482127 17 postix 2026-01-05 21:59:29 +0000 (In reply to danielvarella from comment #11) > I successfully implemented Chome extensions support for Falkon. May I ask if it supports manifest V3 in order to have a full fledged adblocker in Falkon? 2482415 18 fourstringsplayer 2026-01-06 20:39:25 +0000 (In reply to postix from comment #17) > May I ask if it supports manifest V3 in order to have a full fledged > adblocker in Falkon? Yes. According to QWebEngineExtensionManager, "Only ManifestV3 extensions are supported, other versions won't be loaded nor installed" I'm also eager to see extensions like uBlock Origin, Dark Reader and Video DownloadHelper working in Falkon.
