Hi

uBlock Origin gone for Thunderbird.

How Can I Block Annoying Ads in Newsletters?

https://services.addons.thunderbird.net/En-uS/thunderbird/addon/ublock-origin/ ==> I get the eror “Forbidden” in Safari and Mullvad Browser.

The correct link for the addon is https://addons.thunderbird.net/en-US/thunderbird/addon/ublock-origin/

Digging a little deeper Releases · gorhill/uBlock · GitHub

GitHub - uBlockOrigin/uBlock-issues: This is the community-maintained issue tracker for uBlock Origin · GitHub states “Thunderbird: Download the most recent Block0_[version].thunderbird.xpi file from the uBO Releases page, then drag-n-drop it into Thunderbird’s Add-ons Manager pane (Thunderbird 91+ required).” Maybe it works?

Unfortunately, uBlock Origin for Thunderbird is no longer maintained, so the old add-on isn’t a good option for current Thunderbird versions. For blocking unwanted content in newsletters, it may be better to use Thunderbird’s built-in remote-content/privacy settings and adjust your mail/newsletter preferences where possible.

If the main issue is tracking pixels rather than ads, Thunderbird’s remote-content blocking can also help prevent external images from loading automatically.
