Adjust the maximum number of static rulesets and enabled rulesets

[105th]

Proposal

We at AdGuard suppose that the limits should correspond to the functionality of MV2 extensions and this is currently not the case.

Increase the maximum number of static rulesets to 100

The reasoning is rather simple. We checked the number of filter lists that are included into three popular ad blocking extensions and here is what we got.

• AdGuard provides a choice of ~80 filter lists
• uBlock Origin provides a choice of ~60 filter lists
• Adblock Plus provides a choice of 27 filters

With the current limit of 50 rulesets we won’t be able to repeat this functionality. To conclude, we think that the maximum number of rulesets should be increased from 50 to 100 so that we didn’t reduce the users choice compared to MV2.

Increase the maximum number of enabled rulesets to 20 or higher

In order to find out what would be the adequate maximum number we analyzed public issues (raw values) from AdGuard users from the AdguardFilters repo.

It appears that 25% of AdGuard users have over 10 filter lists enabled.

In addition to that, uBlock Origin by default has 10 filter lists enabled.

If the limit is increased to 20 it will not solve all the transition issues, but it will at least be a problem for just 7% of the users.

@oliverdunk hi Oliver, just wanted to remind about this one, is there any update? I saw that the limits were mentioned in the known issues so I reckon it means that Chrome is supportive?

We're definitely supportive of the general concept, and as you mentioned it's on our list of issues to resolve before announcing a new MV3 timeline. We do still want to have some discussions internally about exactly what limits to pick - at first glance your suggestions seem reasonable but we need to spend a bit more time on it just to make sure.
