@A_Nonimo, you said that you don’t think V.5 has the feature to block specific hosts, but I believe that when you look at the log and see an entry that was allowed, but you want to blacklist it, it looks to me like that will put that questionable entry in the blocked list. I think that’s the technique you were recommending to me. So the feature may be in Ver. 5
Edit: Let me attempt to clarify my comment - in V4, when I go to the log and “allow” an entry that was blocked, Blokada puts it in the whitelist and it gets added to the “Allowed Hosts” list. You had mentioned that in V5 it would be in the “exceptions” list. You also said that you could manually add exceptions. Perhaps it’s just a change in terminology, V4 to V5? (Conversely, in V4, blocking an entry in the log to put it in the blacklist adds it to the “Blocked Hosts” list.)
Edit 2: I’ve been reluctant to reinstall V5 because my past experience of downgrading caused V4 to start the clock over on the gazillion blocked counter, which I love to see. (Also, note on the Blokada download site that V4 “has more features.” However, I thought I’d be clever and install V5 into the secure folder of my Samsung Note 8. You may be aware that the Samsung secure folder installs separate instances of apps. For example, you can text between two Signal accounts that way (useful for testing anyway).
So, now I understand what you’re dealing with in the “My blocklists” (“Blocked” and “Allowed”). I didn’t see any way to manually add an entry in My Blocklists other than by using the Activity log. The manual entry method is in V4 but not V5. Also, I see that a log entry that has been changed to block or allow is annotated with “modified.” I don’t believe the V4 log shows that.
Interestingly, when Blokada - installed in the secure folder - is activated for ad blocking, it only monitors or blocks activity for apps that are installed and run from the secure folder. Main apps and activity on the device are unaffected.
Whoops! I see that V4 is now completely gone from my Note 8, so not so clever after all. I’ve installed V4 again for the device as a whole: “Ad blocking is active, 1 blocked since 11.06.21” I wonder if the “App Cloner” app will allow V4 and V5 to be installed simultaneously (with only one one ad blocking activated at a time).
Oh, I noticed under the List Status of V4 (in Ad blocking settings) this statement: “Filters counter
Filters are now configured with 101,780 rules. Your device allows max 256 MB of memory for every application, and up to 1.93 million rules can fit into it.
Remember, this is just an estimate and Blokada utilises the most memory when it merges the lists. If you enabled a few of them recently, wait a few minutes for the system to free up memory.” And the number of rules is stated on that settings screen as shown in the screen shot below. The number does change consistent with adding more lists; for example, it goes up from 101,780 to 219,354 rules when I add hBlock to CPBL. You can probably calculate the deduplications by playing around with Host Lists selections and checking this number in List status.
Thanks again, @bongochong for a wealth of great information.
