(WebExtensions :: General, defect)

Description

Attachment: screenshot 2023-05-14 201021.png

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/113.0

Steps to reproduce:

I have listed again the same problem. Opening 1-2 tabs leads to extreme - full CPU throttle/usage.

Actual results:

Nothing happened even I erased cookies etc - even on troubleshoot mode cpu is close to throttling.

Expected results:

You should have provided a solution after all the messages I've send and you should have fixed this cause it is inevitable that using Mozilla Firefox would not be an option anymore.

Hi @Pauseinio could you reach about:support in URL > select Copy Text to Clipboard > Paste it into a text file and attach that to this bug as well ? also the two websites you are seeing this issue on, I could try to reproduce this issue after I install the addons you have installed and see if the issue occurs on our side.

Also in the mean time can you please try to reproduce this issue in safe mode ? it will deactivate the Addons you have installed in case one of them is causing it. Here is a link on how to start Firefox in safe mode :

So sorry to inform you that due to the constant inconvience that I suffer using Mozilla Firefox and due to the absolute lack of any form of solution provided, I' m forced to use other browsers. Mozilla is no longer a viable option for me after sooo many years. Hope you find a workaround cause I no longer play with along.

What' s the point of starting constantly Mozilla Firefox at safe mode? Is that the functionallity I used of? I' m crystal clear on what's the symptoms and there have been a lot of explaining the problem. It' s as simple as thatQ opening two - three tabs leads to constant cpu throttle - and I have attached so many screenshots.

Also - since you've been so kind and anwered my complains - I' m using as you can see two Addons - AdblockPlus and Kaspersky Protection. Those two used to work just fine - as whole Mozilla Firefox used to.

We still need these two pieces of information before we can take any action here.

I come to the conclusion that inevitably your suggestion would be something like "try to unistall and then re-install" etc and that really doesn' t seems to be happening. So long Mozilla as ot looks like. Just for operative reasons I' m trying to find out a solution but since there is no one to fix the problem, I 'd rather not bother..

Could you capture a shorter profile of just a few seconds, using the "Firefox" preset (rather than the "Power" preset) in the profiler panel?
The last profile you screenshotted seems to contain multiple minutes of activity. Just 5 seconds should be enough to see what's going on.

In one of your profiles I can see activity coming from the Kaspersky add-on: https://share.firefox.dev/3NfwGEN
Do you still see high CPU usage if you disable it on about:addons? If so, can you record another profile with the add-on disabled?

It seems that the addon Kaspersky Protection causes the CPU throttling - i'll attach a screenshot that I had enabled it and then disabled it that is very enlighting - hope that that was the problem

• should I make a report about the addon? It worked just fine so many years.
• I have to say thank you for your interest and your help in what seems as resolving the bug.

Hello,

I tried reproducing the issue on the latest Nightly (116.0a1/20230611214645) and Release (114.0.1/20230608214645) under Windows 10 x64, but without success.

I installed the Kaspersky Protection 2021 extension and opened a few tabs as per the STR and then monitored the CPU usage. With only the extension installed, CPU usage was normal.

However, the extension by itself does nothing and it requires the Kaspersky AV to be installed, which in turn requires a paid subscription and as such we cannot test it as we do not have the means to purchase it.
