@Kees1958 updated his UBOL DNR filter list.

And kudos to him for sharing his personal blocklist which includes some filters for a few big news sites, including paywall filtering rules.

I'm curious to see if the scriptlet I wrote to enable GPC,along with the DNR rule that complements it on the server side,is working.

 

[Sampei.Nihira]

It doesn't work.

uBol started as a permission less DNR blocker, next added the option to add DNR rules (in YAML format), next it added a cosmetic filter option (with the best rule constructor), next added transforming old ABP rules to cosmetic rules (you can just copy your old ABP rules in to it) and old ABP rules to DNT (well YAML) format. The only prerequisite is that the old ABP rules are constructed correctly (when uBol finds an error it stops).

After these major milestones we got support for procedural rules (currently only accepted through uBol's own filters on uBo Assets) and now it starts to accept scriptlets, making it a great Mv3 extension which is nearly as good as AdGuard (Mv3).

Reallt impressive work mr Gorhill

This is essentially the same build as 2026.426.1536, but with a Safari-specific commit reverted in order to fix an issue when uploading the package to the App store.

It's absurd that the latest available version of uBoL for Firefox was updated from GitHub when there are usually no updates for weeks on end.

And in CWS, we're still on version 507.2008 (two weeks without any updates to the filter lists).
The same goes for uBo in Firefox, which is stuck at version 1.70.0.

The same goes for uBo in Firefox, which is stuck at version 1.70.0.

As I recall, the developer had a problem with Firefox when he added the uBoL to the Mozilla add-ons, so he removed it.

And Chrome had a problem with him once regarding his other extension, so I believe he gave MS Edge precedence over Chrome.

In contrast to uBoL, uBo on Firefox does not require constant updating because the lists are updated automatically.
