List of incompatible extensions

    • Alphatext: Modify the text sizes and spacing between the lines in webpages. It partially works, however, setting the spacing > 1.2 could mess with some images and buttons. Consider adjusting parameters directly in Vivaldi instead.
    • Anti adblock killer.js: A legacy script used in Tampermonkey/Violentmonkey and combined with an adblocker. Better use ublock protector which is less prone to break sites.
    • CookieAutoDelete: IT WORKS. Do ONLY If you have persistent broken popups: 1)save expressions list; 2) uninstall extension; 3) update vivaldi; 4)reinstall extension; 5) restore expressions list [this seems to fixed it in my case]
    • Click and clean: Was heavy on RAM and not fully working.
    • DevTools Extensions: While usually most of them works, they could be sometimes be broken due a chromium jump (which change quite often).
    • Extension defender: Should check for malicious extensions... but it hangs at "scanning"
    • Flash video downloader 28.2.1: This is the last version which works as expected. Newer versions often have "grabbing issues".
    • Google (Data Saver/Drive/Keep/Tasks/Hangouts): These extension won't work as they uses chrome sync or other api which vivaldi hasn't. Same for extensions which trigger chrome://chrome-signin/?access_point=6&reason=0. You may encounter issues with most G-extensions.
    • Internet Download manager: Versions 6.25 20+ and above should work; Most times the grabber will work and keeping program/extension/vivaldi updated could fix it. Disable/enable extension can be used as workaround if not working on a page.
    • IE Tab multi (enhanced): Use the deprecated NPAPI. So it don't work anymore on Vivaldi and on every chromium browser.
    • IE Tab: Works fine when tabs are up - but it totally overlap tab bar if you use vertical tabs. Some functions are only in "pro" mode - it's a kind of shareware extension.
    • Linkclump: Should work disabling vivaldi mouse gestures,
      which is probably not a good solution.
    • NaCL Support: Is not really an extension - it's a framework plugin (which seems to be "in deprecation" status); sites which use this will work only on chrome.
    • PIP Video: Broken since chromium 56 (based on a experimental flag://). Try Popup Video Player.
    • Several passwords manager: For example, Kaspersky and Lastpass are known to have issues or became incompatible with Vivaldi.
    • Some download managers: Some works, but some other doesn't. Try them all. (Ok, only some).
    • SimpleExtManager 1.4.4+: Newest versions has a "broken" popup; Still using but probably newer versions, or other addons will work too.
    • Some VPN services: some works, some other doesn't.

    • Some "problematics" categories:
      • Extensions for: 1] History; 2] Tabs; 3] Sessions; 4] Windows; 5] Theming; 6] "Save in" extensions; 7] The ones which rely on particular Google APIs. These couldn't work as Vivaldi has its own interface for handle such elements.
        Of course, some of them could work fine if they just use some plain chromium APIs.

    • Sucuri sitecheck: Should check opened site for bad behaviours. It hangs at "scanning".
    • Video Autoplay Blocker: Actually it works well. But it's icon is not shown.
    • Video downloader helper: Not every video grabber works. Try Fast Video Downloader or Flash video downloader which works.
    • Tabs counter: Counting is wrong when incognito mode is on.
    • Video downloader professional: Used to have bad behaviours like ads-in-tabs injecting and considered as malware by Junkware Removal tool (its id: elicpjhcidhpjomhibiffojpinpmmpil)
    • Xmarks: Not developed anymore. It can only "sync" one folder - the one set as "bookmark bar folder"; better wait for vivaldi sync in stable channel ;)

  • None of the drag and search extensions such as "Yet Another Drag and Go" or "Simple Drag & Drop Search" work.

  • Thanks for your comments and sorry for the troubles you encountered. Does the following fix the issues you're having with IDM?


  • Hangouts worked smoothly earlier in older versions of Vivaldi (or older versions of Hangouts?). Now it shows blank window until i open F12 mode and press F5. Or until a new message arrives. So it almost works.

  • The same problem with Hangouts extension on 1.2.485.14.

  • Moderator

    Tabs Outliner also does not work: when you click the extension button, the Tabs Outliner window does not appear.

    I didn't realize there was already a separate thread about the issue here.

  • Moderator

    Made this topic a sticky.

  • Vivaldi Ambassador

    Click&Clean don´t work well and shows only a half meu

  • Rest web service
    Extension won't save anything. (Favorites, Last calls)

    Btw. anyone knowing a working nice REST client for Vivaldi?

  • FVD Speeddial still doesn't work (Mac)

    Live preview dials do not show correctly, updating them causes Vivaldi to open each dial in a new window to refresh (it should happen in the background.

    This is keeping me from using Vivaldi as my main browser as I really like the live previews of my favourite sites.


  • Print Edit does not work.

    How it works in Chrome:
    Reopens current page in new tab, with additional gui bar, where the user select what elements to show/hide before printing the page.

    Vivaldi reopens the current page in new tab, without the additional gui bar.

  • Vivaldi Ambassador

    Google Drive in particular and Google Services in general:

    This is the 1st screen I get to.

    This is the 2nd screen I get to. Nothing.

    This has been reported as a bug, VB-20826, and searched the forum without success on this earlier.

    Ubuntu 16.0.4 LTS on VirtualBox (8 GB - 32 GB storage - 128 MB VM)
    Snapshot 1.3.582.3 Deb amd64

  • Probably most of the extensions which use google APIs/login won't work in Vivaldi (for the moment at least); For what I know, Google Drive is one of them :)

  • Vivaldi Ambassador


    When I did a search on Google Drive and similar, I didn't find anything until I refreshed this page and found the what should be now sticky list that has been updated.

    Elsewhere, it was noted that program that launches other browsers (Chrome, Edge, IE, Mozilla, etc.) will not work in Chrome due to "certain permissions" that are allowed in Mozilla but not Chrome. Since Vivaldi is chromium at it's core, I don't see a workaround for this, BiCBW.{"But i Could Be Wrong"}

  • I found some extensions work only when Opera is installed along. For instance Roboform Password from Google Extension will not work without having Opera installed. Even though I dont use Opera, I have to have it in order for Roboform to work with Vivaldi Roboform installer itself do not recognize Vivaldi. It sees only FF, Opera and Chrome. For Browser Cleaning I use **Click & Clean** because **History Eraser** which I like more doesnt work with VV :S

  • Fleex doesn't work. It should display button on the toolbar, but the button appears only for half a second (after installing/enabling) and then disappears. There's no way to activate the extension without the button.

  • Xmarks downloads only bookmarks in "Bookmarks bar" folder, but not these in "Other bookmarks" folder.

  • Ghostery

    It detects stuff but does not block.

  • Bamboo Spear

    The opened menu-icon options popup is flickering terribly … the plugin works so far, but it's a threat to the eyes.
