Which filters have you enabled under "Security"?

@ameshkov For the purposes of this example, all three, namely Malware Domains, Spam404, and NoCoin Filter List, all of which seem reasonable from the standpoint of a user desirous of protecting their privacy and security.

Generally, the only way to partly solve this 50k issue is to have multiple content blocker extensions in Safari. The problem with this approach is that filters inside different content blockers cannot affect each other (which is sometimes necessary).

So we'll have to do some weird stuff:

1. Add multiple content blocking extensions to Safari:

• General (for Ad blocking, Language-specific filters and Other)
• Spyware
• Social Widgets and Annoyances
• Security
• Other (for Custom and any other category if we ever add it)

2. Rules from the user filter and whitelist will be added to ALL content blockers

hmm, this sounds interesting

I believe one of the key issues is that it is currently very difficult to understand what should be enabled.

For example, in the Other category, there is a filter whose description states…

Special filter for Safari 9+ on iOS and Mac OS. We need a separate filter for Safari browser because it does not fully support our rules syntax.

If AdGuard “needs a separate filter for Safari,” then what are all the other filters doing? The description implies that anything but this filter is incompatible with Safari and seems to make every other filter in the app useless. Yet, this “made-for-Safari” filter, which ships in an app called “AdGuard for Safari” is hidden in the “Other” section…

It is also difficult for anyone not intimately familiar with the various lists to know what extent, if any, they are liable to overlap. For example, AdGuard Annoyances filter and Fanboy's Annoyances no doubt contain different rules, but to what extent is one better than the other?

Regarding your comment above, I believe this is what the popular 1Blocker extension does on iOS, and it seems to be working very well on that platform. I do not know to what extent it could be translated to macOS, since 1Blocker for macOS is more or less dead in the water, but it seems the approach has been battle-tested in theory at least.

This approach will work indeed, we've implemented it already on iOS (it's in the inner test at the moment).

However, most of the filters maintainers don't care about Safari and its limitations, and that's why we should be careful.

Regarding the Safari filter, it was supposed to resolve issues caused by Safari content blocking API limitations. Tbh, it is obsolete and will be removed in the future.

@Mizzick we'll need to prepare the Safari converter for that.

The task is complicated so it's postponed to 1.3 (at least).

@ameshkov
There is something strange about the number of filters:
On iOS (iPhone and iPad) I have 6 lists activated, which make up 48.944 filter rules.

Within AdGuard for Safari I now enabled the IDENTICAL lists (even one less, since I don’t need the 'AdGuard Mobile Ad filter' on my Mac).
However, the extension keeps telling me, that I’m exceeding the 50k limit?!
I have to enable the 'optimize filter' option to avoid the warning! (What does this option do to avoid the exceeding?)

How can this be that iOS says rules are below 50k and Mac says above?
Btw: It would be great if - like in the iOS version - the extension shows the number of currently activated filter rules :)

Moved to 1.4, v1.3 is all about advanced blocking rules: #114

@maciboy
Lists for Safari on iOS and Safari on macOS are different, e.g.
https://filters.adtidy.org/extension/safari/filters/2.txt
https://filters.adtidy.org/ios/filters/2.txt
Basically, lists for iOS don't contain advanced rules (ext-css, script, etc), so they are smaller.

Is here some progress ?

@F3000 the issue is assigned to the v1.4

Willl you implemented it like suggested ?

Yes, but later, we're working on v1.3 release right now

Ok . Have you a new state for iOS beta which will include the different plugins ?

@ameshkov Audrey it's not 100% clear to me, please could you confirm if 1.4 will support >50,000 filters?

The thread seems slightly ambiguous in that it might refer to "resolving differences between iOS & macOS"
or
"resolving the 50,000 filter ceiling"

You see right now users of uBlock-Origin cannot proceed on Safari Technical Preview 80 and are therefore forced to change to alternative adblockers. Since most uBlock-Origin users typically require more than 50k filters, AdGuard is effectively out of the running, save for that critical (comment you made regarding v1.4 which I might have misunderstood). In the meantime, several users have already migrated to a number of platforms and are starting to report back.

Keep it up, very impressive work here!

@Beribis

"resolving the 50,000 filter ceiling"

I guess this one, by adding multiple content blocking extensions to Safari (supposedly, 50k rules limitation will refer to each extension). See #93 (comment) .

resolving differences between iOS & macOS

only ragards multiple content blocking extensions support

This approach will work indeed, we've implemented it already on iOS (it's in the inner test at the moment)
(#93 (comment))

For now the issue is assigned to the v1.4 .

PS:
I like uBlock Origin too, but it never had 50k rules limitation because it never supported Safari content blocking API. In addition, AdGuard supports filters optimization, so even if you use the same number of lists you will have fewer rules.

Well , I have deactivated everything but 1 filter which its ad blocking and still says "too many filters"
