Extensions Will Not Update

[ganakee]

In late June or early July 2025, the ability to update extensions ceased.
The Chromium Web Store pinned icon shows updates available.
However, I can no longer find any method to perform the update. Any method of updating simply downoads the .crx file instead of updating.

Config

• Ungoogled Chrome Version Version 138.0.7204.157 (Official Build, ungoogled-chromium) (64-bit)
• Installed as Flatpack
• Ubuntu 25.04
• chrome://flags/#extension-mime-request-handling to Always prompt for install is SET
• Also, chrome://extensions/ Developer Mode = ON

Notes

If I go to chrome://extensions/ the extensions list but a hover says Not From Chrome Store for each extension.
I have two systems--one Pop OS 22.04 and one Ubuntu 25.04. THe issue ONLY affects the Ubuntu 25.04 system. I compared Flatseal permissions and verything looks the same.
The Allow Access to File URLS trick avialble by clicking each extension from Extensions does not help/work/resolve.

Hi, same behavior as described by ganakee on:
Version 139.0.7258.154 (Official Build, ungoogled-chromium) (64-bit)
Windows 11 Pro Version 24H2 (OS Build 26100.4946)
Chromium Web Store 1.5.5

Add-on failed to update:
uBlock Origin 1.65.0 to 1.66.0

Workaround:
Uninstall old version, install new version.

Thanks.

Just for the record, uBlock Origin specifically requires a browser restart in order to load the updated version. There is a way to override that behaviour somewhere in the extension's settings (with the specific option explained in the documentation), but I don't remember the exact location now.

my experience: all [my] extensions [chromium web store, privacy badger, adguard adblocker] require browser restart in ungoogled chromium to update [the extensions page developer mode update button is not sufficient].

Hello,
Thank you for your responses. Since uBlock recently released a new version, I tried what you suggested:

1. Update uBlock through the Chromium Web Store badge.
2. Restart Chromium.
   It behaves the same way — the version does not update. So I simply used the workaround I mentioned earlier: uninstalling uBlock and installing it again, which updated it successfully.
