How to make your Startpage / Newtab Extension work (again)

[pafflick]

Each extension can use different name of its "homepage" file. As far as I remember, Momentum uses newtab.html for example. If the index.html returns a blank tab or an error you might have to find the name of the file manually.

Here's how:

1. Go to: vivaldi://about (Menu > Help > About).
2. Check the "Profile Path" entry.
3. Navigate to that folder (you can copy the path and paste in the URL bar of Vivaldi) and go to "Extensions".
4. Find a folder with a name corresponding to your extension's ID.
5. Open it and look for HTML files. The quickest way to find the right one (the "homepage") would be to open it in Vivaldi.
6. Once you find the right one, copy its name and use it as the address of your extension:
   chrome-extension://ID of your Extension/"homepage" file name.html

Go to the extension site (vivaldi://extensions or press "Shift +Ctrl + E") and click on "Get more Extensions" to get redirected to the chrome store.
Search in the searchfield for the extension you want. Than click on the extension so the popup show up where you can read the infos, reviews and stuff.
Now look at the url-bar because you need the specific extension ID which starts after the name of your extension in the url

Actually, the extension ID is written in the Vivaldi Extension page in the field describing each extension

@TbGbe
Thanks I didn't knew that either.
So for everybody seeking the Extension ID:
Go to vivaldi://extensions (or press "Shift + Ctrl + E") next hit "Developer Mode" and copy the extension ID.

@Boombastic I just tested it with tabmark extension, and exactly the index.html link you pasted works for startup page. Make sure you press "Add" after copying it to the specific page field.

@Boombastic I am not completely sure about this but I think that this was already reported

[zaibon]

I am writing this to complete this thread and in case somebody might end up here via google in search for answers.

Starting from the new Snapshot 1.10.838.7 ongoing there is the option in the settings menu to give extensions control over your new tab.

To activate the new feature you need to install the extension that should change your new tab in the first place - otherwise the option won't be available !!
Than go to:
Settings --> Tabs --> in the section "New Tab Page" there should be an option called "Controlled by Extension" --> click it
==> Done

EDIT: Oh and thousand thanks to the devs that implemented this ^^

newtab.html

Tried it but not working for this extension - https://chrome.google.com/webstore/detail/monknow-new-tab-personal/lnbjajkbekhkgablenknhapphbdbldeh

@smerugu28 Of course it doesn't work - it's a different extension:

Not sure if it's still the case, as the post you're replying to is 5 years old. But I guess it's worth the try - I explained how to find the extension's "homepage" file manually (if it happens to be something else than index.html), to add to the OP's method.

@pafflick Another tip is just to open Devtools and reload the page. The page will be the first request.

Saves having to guess what the correct HTML file is, as it's not always obvious - in this case hiding under asset/html.
