Additional Information

This bug may also be present in other browsers, check.

(Memory leak in 2024 imagine)

Using since 2011.

Yes, it is present in other browsers: Slimjet, for example. That's an outdated browser to be sure, but at least it points away from Chrome. This never happened with the MV2 version.

This has been present for the past several versions and still persists for 5.0.138. A web page/tab that is open for a significant period of time and/or one that causes a lot of AdGuard extension blocking will cause an out of memory error. I've seen it in Edge, Brave and Vivaldi. I've had to stop using the extension and revert to uBOL in the meantime.

Still present in 5.0.161

I guess no one has looked at it yet. Maybe this is the wrong way to report.

@jimsinenomine @JohnSheppard11 @rpodric
Please reproduce the problem and open Task Manager in Chrome (Shift + Esc). How much memory does AdGuard consume and what is the CPU load? Can you reproduce the problem consistently on certain websites or can it happen on any website?

A web page/tab that is open for a significant period of time and/or one that causes a lot of AdGuard extension blocking will cause an out of memory error.

How long does the page have to be open? Do you just leave the page open or refresh it or click something on the page? Do you have any memory-saving options enabled in your browser?

It would also be great if you attach your AdGuard extension settings in the comment.

The ones it's happened on for me are "voice.google.com" and "mail.google.com" (as PWA). I have them permanently open in Edge. Settings are attached. I've turned the extension back on and it should cause the error again (although I did notice an update to 5.0.162). Assuming it errors, I'll then do the task manager checks and report back.

I just leave the page open. No refresh (auto or manual). Memory setting in Edge is the default "Balanced savings".

In my case, it must have been YouTube, if the site matters at all, which I'm guessing that it doesn't, since I don't use that browser for anything else. I think it's much more the time on a given site rather than the site.

[jimsinenomine]

Here you go re the error and the task manager. Not sure how much it helps. There's a theme here - in case anyone didn't notice 🙂 i.e. Google-owned web sites (Voice, Gmail, YouTube, etc.). Took 10-12 hours for this error to show up. HTH.
