A unknown addon in firefox addon store with 4.5+ rating.
(From, most of the comments it’s seems like this addon is suspicious and don’t have enough proof or evidence to trust it with our data. So please everyone avoid using this addon. A better one is “UBLOCK ORIGIN”).
They will use popups asking you to upgrade to a premium version:
https://adblockultimate.net/pricingWhich is kinda silly when they seem to mostly copy the work of others:
https://github.com/mozilla/addons/issues/1078I second the uBlock Origin recommendation.
Well that’s shady
If you’re using Mozilla’s level of endorsement as a metric, note this prominent disclaimer on the addon’s page:
⚠️ This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing.
ublock origin does not have this disclaimer. It works well and is widely trusted.
Localcdn, I still don’t care about cookies like addons have this warning too…
Why not use uBlock? Widely used and gets job done
I didn’t say no ublock. Just asked about this one
Check the licence.
If it’s not any open source licence then fundamentally not trustable.
Why below firefox shows it under GNU GPL ?
I’m not going to tell you what to use instead, but how you make the judgement for yourself: audit the code yourself
The source code is linked right there, and you don’t need trusting someone to make the call. You’re making the call. Mind you, the actual add-on installed from Mozilla Add-Ons might contains different code then what shown in the repo. I never release any add-ons so that is just a wild guess and a hint possibility this could happen.
To give you an head start: look for URLs and any encoded strings in all files, be it Base64 or something else. And follow them to find out why there it is there, how is it triggered, etc. Same goes for encoded strings with the added question: what was encoded within.
Still, that is just the basic, and I’m not too into JavaScript but there could be other ways of hiding information, like in an image file via steganography.
Why not DNS level AdBlock?
I hope dns level blocking is less effective that browser level. Also dns level blocking cant apply cosmetic filters and give a clean view of webpages.
