Possible MB Browser Guard v2.3.17 Bug - Manage Blocked Site Warnings

[lmacri]

I have the latest Firefox v97.0.0 (updated 08-Feb-2022) and Malwarebytes Browser Guard for Firefox v2.3.17 (updated 10-Feb-2022).  I also have Malwarebytes Premium v4.5.2.157-1.0.1562 (updated 20-Jan-2022) running in real-time protection mode.

For the past few days I've been getting a pop-up asking me to allow Malwarebytes Browser Guard to manage blocked website warnings for Malwarebytes Premium every time I launch Firefox. I would click "Allow" every time but the pop-up would return the next time I launched Firefox.

 

I checked my Malwarebytes Browser Guard settings today and was surprised to see that:

• The Hide Duplicate Warnings setting that was previously enabled was disabled (I don't know if the recent Firefox update or MB Browser Guard extension update turned off this setting).
• Clicking "Allow" on the pop-up shown above did not enable the Hide Duplicate Warnings setting

 

I was able to fix the problem by turning on the Hide Duplicate Warnings setting in MB Browser Guard (and saw a different pop-up requesting that I allow MB Browser Guard to exchange messages with programs other than Firefox), but I assume I shouldn't have to do this manually if I've already clicked "Allow" in the original pop-up to permit MB Browser Guard to manage blocked website warnings.

Is it safe to assume that this bug was fixed in Malwarebytes Browser Guard for Firefox v2.3.18 (rel. 16-Feb-2022)?

I have no way of knowing since I already turned on "Hide Duplicate Warnings" in the extension settings last week to stop the repeated pop-ups, and the change log for v2.3.18 at https://addons.mozilla.org/en-US/firefox/addon/malwarebytes/versions has no description of the changes.  However, it looks like other threads on this same topic were recently marked as solved.

v2.3.18 was a hot fix for all the false positive findings involving Shopify services to multiple seller sites, so there's a good chance that it is not safe to assume the bug you experienced was fixed by it. I don't understand why you say you have no way of knowing. Why don't you simply turn off "hide Duplicate Warnings" to find out?

According to internal changelog, this was fixed by 2.3.18.

Hi alvarnell:

It's difficult to test if my issue is fixed because I'm not sure what expected behaviour is for the latest MB Browser Guard v2.3.18.

I checked my MB Browser Guard v2.3.18 settings yesterday and discovered the "Hide Duplicate Warnings" has once again been automatically disabled (recall my original post <above> where I said I  manually turned ON "Hide Duplicate Warnings" in v2.3.17 on 11-Feb-2022 to stop the constant pop-ups asking me to allow MB Browser Guard to manage blocked website warnings for  Malwarebytes Premium).

 

That suggests that "Hide Duplicate Warnings" was likely turned OFF (either inadvertently or deliberately) by one of the following updates:

• Malwarebytes Premium 4.5.4.168-1.0.1599 (installed 15-Feb-2022)
• Malwarebytes Browser Guard for Firefox v2.3.18 (installed 16-Feb-2022)
• Firefox v97.0.1 (installed 17-Feb-2021)

I haven't seen another pop-up asking me to allow MB Browser Guard v2.3.18 to manage blocked website warnings for MB Premium since 11-Feb-2022, so as far as I can tell my MB Premium v4.5.4 is currently handling my blocked website warnings and will continue to do so until I go into my MB Browser Guard v2.3.18 settings and manually turn ON "Hide Duplicate Warnings" again.

That sounds like there's still a glitch in MB Browser Guard v2.3.18, unless I don't understand how the blocked website warnings are being handled between MB Browser Guard and MB Premium now.
