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 and is updated.

    Bookmark&History extensions: Most of them won't work as Vivaldi use their own management. Of course, very few of them may works.

    Chrome Apps: May work but may also use chrome APIs which are not supported in Vivaldi. Furthermore, apps support is in deprecation - and they will work only on ChromeOS devices soon.

    Chrome APIs (depends on): Some extensions are heavily bind with google browser and call specific APIs that chromium - Vivaldi and most other blink based browser hasn't. Usually, such extensions trigger chrome://chrome-signin/?access_point=6&reason=0 (chrome sign-in) which isn't supported.

    CookieAutoDelete: Actually it works. This may help you only if you encounter a persistent broken popup: 1)save expressions list; 2) uninstall extension; 3) update vivaldi; 4)reinstall extension; 5) restore expressions list [This how I fixed in past].
    NOTE: If popup is still often broken, use Vanilla Cookie Manager instead (follow instructions or you'll lose cookies).

    Chrome themes: No chrome theme will work as Vivaldi don't use chromium UI at all. (Addons like osprey/stylus will work fine).

    Click and clean: Was heavy on RAM and not fully working. Consider native cleaning options (ctrl+Maiusc+Canc on WinOS).

    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. 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.
    If is not working on a page: disable and enable extension + reload page (F5) can be used as workaround.
    NOTE: Ensure IDM addon is at least on 6.32.3, works better especially on latest snapshot/stable versions.

    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. (Let me know if it was fixed).

    NaCL Support: Is not really an extension - it's a framework plugin which is in deprecation status.
    Sites which use this will work only on chrome.

    Omnibar/Omnibox extensions: Vivaldi don't use the chromium urlbar, so the omnibox feature is not existent. No extension for this will work. Same for flags.

    PIP Video: Broken since chromium 56 (based on a experimental flag://). Now is integrated in chromium/vivaldi (right click twice on html5 videos). If not available "force" PIP with this.

    Save in... extensions: They rarely works fine (or are annoying to configure). This also because the chromium api for such tasks is flaky.

    Sessions/Tabs/Windows extensions: Most of them won't work, but very few may works. This as Vivaldi manage these elements on its own.

    Several passwords manager: For example, Kaspersky and Lastpass are known to have issues or became incompatible with Vivaldi. Bitwarden and Keepass seems to work fine.

    Some download managers: Some works, some don't. You may try Chrono Download Manager which works.

    SimpleExtManager 1.4.4+: Newest versions has a "broken" popup; Still using but probably newer versions or other addons will work too.

    Sucuri sitecheck: Should check opened site for bad behaviours. It hangs at "scanning".

    Tabs counter: Counting is wrong when incognito mode is on. Window panel actually has the same feature.

    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.

    VPN extensions: Most of them will work, but some may have issue ons Vivaldi (if they made only with google in mind). Report in the thread if your don't work.

    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 😉

    zzllrr Imager Geek (ZIG): Still works, but multi-tab grab is worse in latest chromiums. Not sure if it is a vivaldi fault as the rating in the store is quite low now (3,5/5).
    NOTE: Seems to work fine now. But grabbing results may change.

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

  • Vivaldi Team

    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.

  • 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?

  • 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.

  • 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.

  • Hadden89

    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.
