Extension causes Chrome to crash.

AdGuard VPN Browser Extension version

v2.0.16

Issue Details

Many users have told us that after updating to v2.0.16, Chrome sometimes crashes and uses a lot of memory. This issue has been created to collect these cases in one place. Please add as many details as possible, like os, chrome version, settings, and steps to reproduce.

[Birbber]

In order to reproduce you might try disabling the extension for a long time (almost a day and more) and then enabling it.
The browser will freeze trying to load the extension, then it will crush.

[maximtop]

We think that it happens due to a big storage size, which will be fixed in this issue #117

good thing it's not just me, I've had this issue for several weeks already

I use 4 browsers in total (Chrome, Brave, Edge & Vivaldi), at first I had Brave crash every morning and couldn't figure out what it was, then eventually Chrome and Edge started crashing as well so it had to be something to do with the VPN as in Vivaldi I don't use it and it's worked normal all this time

the worst part is that it doesn't just crash once but after you reopen the browser it does it again and again, like the browser becomes completely unusable
once you manage to load it (after like 10 crashes) and disable the VPN the browser starts working again (but once you enable the VPN again the browser crashes immediately)

I'm on Win 10 and VPN version 2.0.16

The issue has been resolved in the beta version, will be pushed to the release stage on monday.

Meanwhile, reinstalling the extension will fix it as well.

back to crashing for me again 😕

[maximtop]

@lica98 in Chrome?
Does this happen when you start the browser after the PC wakes up from sleep?

[lica98]

@maximtop in all browsers (Chrome, Edge, Brave)

Does this happen when you start the browser after the PC wakes up from sleep?

yes, you turn on the PC and browser is "not responding"

tho this time at least it only crashes once and once you restart it it works normally

[maximtop]

@lica98
We had the opportunity to study the same case and found that the issue isn't related to the extension, as the browser can't automatically start the extension after the PC wakes from sleep.
If you can provide a crash report, we can report the issue on the Chrome bug tracker. Here are the instructions on how to do that: https://www.chromium.org/for-testers/bug-reporting-guidelines/reporting-crash-bug/

[lica98]

so I turned off all the VPN extensions last night before putting the PC to sleep and today when I turned it on:

Edge is "not responding" first then crashed
Chrome seemed to be ok at first but then crashed
Brave is the only one to work, didn't even crash when I turned back the extension

btw I just tried turning the extension on in Edge and it went "not respondning" immediately... other browsers seem to be ok

[LlamaUnicorn]

I can confirm that I'm experiencing this issue on Ubuntu while using the Chrome browser. When the extension is enabled, after rebooting my PC, Chrome crashes multiple times before it eventually starts running. However, when I disable the extension, Chrome starts without any issues. Then, if I re-enable the extension, Chrome crashes once again.

[ameshkov]

After a more deep research of the issue it seems that we found the root cause of the issue and it is a bug in Chrome's chrome.alarms API. This is a relatively new API that's supposed to replace setTimeout for MV3 extensions. It somehow randomly messes up the extension startup. We'll see if we can avoid using alarms API as a temporary solution until it gets fixed.

Chrome bug issue is here:
https://bugs.chromium.org/p/chromium/issues/detail?id=1472759

[ameshkov]

Quick update: we'll remove chrome.alarms in a hotfix update and continue discussing it with Chrome team, I hope they'll fix it and we can get back to using alarms API again.

[LlamaUnicorn]

Would you kindly post an update here when the alarms are removed?

Beta is already published

[Dan-Master]

Beta is already published
2.0.31 is already good, chromium launches without problems and doesn't crash when the extension is enabled!

[lica98]

how do I do that?

[maximtop]

Install it from chrome web store https://chrome.google.com/webstore/detail/adguard-vpn-beta/kfjjacionkafnmnjhdghdfoinihnijgn

[lica98]

Brave still crashes even with beta 😕

[maximtop]

Brave still crashes, even with the beta version. 😕

@lica98, we've received reports from other users saying they aren't experiencing this issue in Chrome anymore. Could it be a Brave-specific issue that might be resolved when they update to Chromium 115?
