The Bugbug bot thinks this bug should belong to the 'Core::WebRTC' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Hi quorum
thanks for attaching the memory report.

Are there any specific steps to reproduce on my machine? any website i should be going to? or steps i should be following in order to reproduce?

thanks

Hello Pablo.

Nope there is nothing special to do. You should be able to reproduce the issue with the same configuration.

As mentioned non-issue with FF production build v91. Less than 250MB memory use, which seems more reasonable.

Best.

Hi andrew
do you know what would be the correct component for this bug? I am unable to reproduce
thanks

[Andrew McCreight [:mccr8]]

Looking at the memory report, the web extension "AdGuard AdBlocker" is using around 2.2GB of memory. We can move it to the web extensions component, though I'd guess that it is more likely that there is an issue with the extension itself that should be reported to the extension developer.

As a workaround, the original reporter could try a different ad blocker, like uBlock Origin.

Hi Andrey, can you please look into what's happening here, perhaps you've had similar reports from other users?

Comment 7

[Andrey Meshkov]

Hi Tomislav, thanks for CC-ing me.

Yeah, according to the memory dump this is definitely our issue.

@quorum75 could you please report it to us directly? https://github.com/AdguardTeam/AdguardBrowserExtension/issues

I can't reproduce it with the default config so we'll need to know your AG configuration and what lists you're using.

[Luca Greco [:rpl] [:luca] [:lgreco]]

Hi @quorum75,
Andrey pointed out in comment 7 that this bug should be reported in the extension issue tracker (linked in comment 7).
Would you mind to do that?

In the meantime I'm also closing this bugzilla issue as "moved".
