It is interesting to note that the signed xpi file for Firefox is corrupted.
I will not report this to Gorhill.

Is there a logger for uBo lite? If there is I can't see it. It seems necessary that the logger be included. How else are we supposed to make exclusionary rules?

The version I used a few days ago did not have one. That is why changed back to AdGuard Mv3 a few days ago.

uBol cosmetic rules picker/creator is very good and when you enable developer mode you can paste old fashioned ABP rules into it custom DNR and they are converted to DNR format for your.

Autoconverts the old uBO lists into lists compatible with MV3?

I was hoping that was not the case. I'm in the same boat as you, preferring ADGmv3 for that reason. But it uses an insane amount of resources. 300 meg for basic lists and 500 MB ram is nuts!

Wel yes and op. Bot the custom cosmetic rules and custom DNR rules accept copying in old format ABP. The custom cosmetic will filter out the cosmetic rules and the custom DNR will translate (simple) ABP rules into DNR. There is also a maximum.

Too much work.

Still using MV2 uBO in Edge, and I may consider shifting to Brave after Edge stop supporting MV2 anymore, rather than using uBOL.

Well I have 16GB Ram and on Linux, so memory usage is not an issue for me. In my surfing profile it uses 180K with AdGuard's base. tracking protectiion and url parameter remove filter list (and some 150 user rules). In my work profile it uses 90K with only 100 custom rules.

You have two options.

1. Use the browser Development tool (or)
2. Use the AG/uBo log.
