Why does Recorder Causes Reddit, Verizon, Spectrum Sites to Not Load?

Over the past six months, I have noticed that when I have Katalon Recorder active as a Chrome Extension, I cannot load posts from reddit.com and my billing sites from verizon.com and spectrum.com. The sites will open in a new tab and then kick the processor up into high speed and never load the page. If I disable the Chrome Extension, they load without issue. I have done a one-by-one extension check and the issue only exists when the Katalon Recorder extension is active in Chrome. Anyone have any ideas?

I’ve also been encountering this issue for several months now (and it has caused me a lot of frustration, too), but had not yet taken the time to audit each extension one by one (…I have many), but having just tested only disabling KAR today, I confirmed that this issue is ‘resolved’ by disabling Katalon Recorder.

@Elly_Tran @albert.vu @vu.tran This seems like a pretty severe bug to have out in the wild.


I agree this might be a severe bug. Let me raise the ticket and double check if we can reproduce this case. Can you please provide us with the KR version, Chrome version you have been using as well as any error log if yes. Thank you!

KR version 5.9.0
Chrome Version 114.0.5735.199 (Official Build) (64-bit)

Edition Windows 10 Pro
Version 22H2
Installed on ‎2/‎11/‎2021
OS build 19045.3086
Experience Windows Feature Experience Pack 1000.19041.1000.0

No error log because it doesn’t happen when I’m running a script. I think that Google Earth (web version) also now has a difficulty.

I’ve tried to trace down an error log when this happened to me (as I was hoping to identify the culprit), but there wasn’t any apparent console log entries to point to when this has happened (at least not that Chrome surfaces before ‘hanging’ the tab).

I’m using (the latest) Chrome, Version 114.0.5735.198 (Official Build) (x86_64) (on macOS) + KAR Build 5.9.0 as well.

Another site I can immediately recall it happens on is Currys.co.uk (it may load the homepage, but the moment you try to click on anything, it hangs).


Thank you for your information and I have raised tickets for our development team. Back to you soon if any update. Thank you!

Hi im update chrome, and is working done :sunglasses:

I am still experiencing the same problem… and I have updated Chrome. There is no resolution.

I’ve also updated Chrome, and can still reproduce the issue.

Does anyone have any update regarding this? Update from the development team?

Has anyone found a way to solve the problem?


Sorry for my late response. I will check with my team and back to you soon

Not claiming it’s a solution, but as a ‘workaround’ you can specify to only launch KAR on click, or on specific sites, so it stops this having the same impact.
