I'm trying to install extensions from the Google web store using the latest no-sync Marmaduke from:
https://chromium.woolyss.com/

Brave works fine.

I don't have a macOS system available to reproduce this, but it seems likely this is caused by another extension modifying the store page in some way. Does it still happen with no other extensions enabled?

I disabled all extensions and no change

you can just install them manually and then update them with chromexup

Are you saying this isn't a bug?

Usually Chrome policies doesn't allow any extension to modify content of the website https://chrome.google.com/* because an exploiter could modify the add to chrome button to make the user install his extension without they notice.

first try to disbale safe browsing and see if it works.
if it doesn't show us your chrome://policy/

EDIT: also make sure in the extension options it has Site access enabled

I am having the same issue on Windows 10 with Marmaduke's build.

I'm on the same situation, I cannot install the Chrome web store CRX file via drag and drop, even with developer mode enabled. Using Windows 7 SP1 with Ungoogled Chromium version 79.0.3945.130 Developers build (64-bit).

Just extract the crx file in a folder and load it in developer mode( See here #10 )
DragNDrop doesn't work on Ungoogled chromium for KDE in Linux too.

You can also try this: https://ungoogled-extension.github.io/

You can copy the link to your extension in it and the installation request will pop up if you have the mime configuration to always.

Well, I was able to install your extension with this workaround, but I cannot install any other extension from Chrome web store. Thanks anyway.

I have the same issue as @boblo1. Using Win7SP1, with Ungoogled Chromium version 79.0.3945.130.
I am not using ver 80 from https://chromium.woolyss.com/.
My Policies page looks the same as ballo shown earlier in the thread.
MIME type requests is set to Always Prompt
image

I have downloaded the crx file then drag/drop into chrome:extensions page.
(I have tried another crx..https-everywhere-chrome-2019.11.7.crx, it did not work either)

I get the puzzle piece icon with "Drop to Install" But then nothing happens.
image

If I use "Load Unpacked" (in Developer mode) and point to the folder with the crx file.. it shows
Failed to load extension
File
~\Downloads
Error
Manifest file is missing or unreadable
Could not load manifest.

Next I have tried using this https://ungoogled-extension.github.io/ I copy the link and click Install, it downloads the crx file then it shows it is adding to chromium, but it goes on forever and never completes.
image

Any other suggestions to have crx files to install?

So I was also enountering this issue; just to add a few more bits of info, I attempted to roll-back my version of Ungoogled Chromium (earliest version with installer executable was 78.0.3904.70-1), and it now fails a little more verbosely (or actually fails in the case of the "adding to chromium" issue), but same behavior that @backoffu2 noted otherwise.

Edit: the learn more link shown above attempts to load a dead support link that seems to be about "CRX-Warning"
https://support.9oo91e.qjz9zk/chrome_webstore/?p=crx_warning

This all seems to suppport that the extensions are being treated as though they were installed from somehwere other than the chrome webstore. Some searching indicates a startup parameter may be the workaround: https://www.ghacks.net/2012/06/12/chrome-fix-extensions-apps-and-user-scripts-cannot-be-installed-from-this-web-site/

Correction, the startup parameter does not work. I also tried loading the crx file directly, which attempts to install again and then states:

Edit Again: Just to clarify, this is before adjusting the mime-type flag; after updating to always prompt, it behaves exactly how @backoffu2 described

I was having a similiar issue with chromium on win7 64bits, but unpacking with 7zip and manually loading extension worked just fine. I'm confident whis will also work when I install it on all my other Linux machines. Many thanks
