Additional Information

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

(Memory leak in 2024 imagine)

Using since 2011.

[rpodric]

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

[rpodric]

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.

[jimsinenomine]

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.

[jimsinenomine]

Issue remains in 5.0.164

[rpodric]

I know there's a bit of a coincidence since all the sites mentioned so far relate to Google, so it may be instructive to try to replicate on some unrelated site, like Wikipedia or whatever else.

[scviktor]

Can confirm the same behavior on Windows 11 with GoogleChrome 130.0.6723.92 and AddGuard Extension 5.0.164. The problem occurs after a few hours of inactivity on various websites such as: E.g. support.sap.com and others.

The tabs appear blank with an “Out of Memory” error message and a high memory usage of 1GB to 4GB. System memory of 40 GB RAM almost completely used. Closing tabs frees up storage space accordingly.
Disabling the AddGuard extension will completely resolve the issue.

[JohnSheppard11]

I don’t see the point in dumping anything, all open sites from the very opening start to slowly gain size in RAM, after 5 hours several GB are accumulated.

I don’t know how and where to open the settings, and I, with 5 open windows and 200 tabs, have no desire to risk losing data and turn on extension again.

I'm too lazy to log in to GitHub again and write something, I can't provide data from the logs and extension settings due to the large number of open tabs. So please don't expect any answers from me from now on. I provided everything I could provide.

So, to begin with, I recommend you to perform a global rollback to a stable version, then look for the causes of the bug, and redo all the tests properly, so as not to lose your audience and rating, which will be quite difficult to get back.

Not fixed in 5.0.167

[windwak3r]

We are preparing a possible fix for this problem. Further discussions will take place at #2594

[rpodric]

Isn't that thread, a year old, about the MV2 version though? I never saw the problem with MV2.

This version is only for Chrome not for Firefox :-(

[maximtop]

There will also be a fix for Firefox. It is currently under review.

The Firefox version of AdGuard AdBlocker (4.4.48) is currently under review in the Firefox Add-ons store.

[Tasiorsa]

Firefox 132.0.2 - Adguard 4.48 and after 48h still the same problem
