Firefox won't load webpages

[nuttynoah]

Mac Ventura M1.

Firefox won't load pages with Kaspersky Standard on.
It worked fine with Internet Security.
When I turn off Kaspersky then Firefox works perfectly.

I have to 'reload' every page for it to display.

I have disabled any extensions.
Do I need to change settings?
I have uninstalled and reinstalled both Kaspersky and Firefox.

Hello, 

Welcome. 

It's weird. I have also Firefox but I never had problem like you. 

You should try reset Firefox settings maybe? 

[nuttynoah]

I have reinstalled Firefox from scratch.

Hello, @nuttynoah

It worked?

[nuttynoah]

Unfortunately not.

The problem is clearly Kaspersky.

I was hoping that I just need to change something in the settings?

Try reinstall kaspersky - Uninstall kaspersky and do restart pc. After this install kaspersky manual update databases and restart pc, then check the problem.

[nuttynoah]

Sorry but i've already tried this.

Will it really make a difference if I do it again?

Did you had any other antivirus installed before kaspersky? 

[nuttynoah]

No, I've been using Kaspersky for a very long time (maybe not much longer)

[nexon]

And you upgraded kaspersky or something? Before working fine and now not works?

Hello @nuttynoah, 

1. *Also* exit Firefox, in Kaspersky, select General, select Protection - *uncheck* Check secure connections - start Firefox, do Firefox webpages show? 
2. When the webpages *don't* resolve - what do you see - a totally blank page - an error - something else? 

Thank you🙏

Yes, I previously had Internet Security, for years, and it was great.

Then when I installed Standard the problems started.

This seems to have fixed it!

Will I have any security issues having unchecked Check secure connections ?

Contact Tech support... Unchecking or disabling something is not solution.
I never unchceck something in my antivirus.

Hello @nuttynoah,

Brilliant! Well done!

We'd like you to submit the issue to Kaspersky please - a conflict b/w Standard & Firefox is not normal, & the *workaround* is more to test IF the issue resolves rather than provide an *actual* solution.... 

Please log a request with Kaspersky Customer Service  - https://support.kaspersky.com/b2c#contacts  - 
on the support page, select either Chat or Email, then fill in the template as shown; please include a *detailed history* Support may request logs, traces & other data, they will guide you:  

Please share the outcome with the Community, when it's available? 
Thank you🙏

Hello，

Try to disable KL product self-defense and exit it.

Go to "C:\programdata\kaspersky lab\AVP21.xxx\Report", delete all file in that folder.

restart KL product, any better?

Regards.

[nuttynoah]

I've emailed them and will let you know what transpires.

Many thanks for your help and have a great day.

Because it is only under Windows and not MAC...

I have uninstalled and reinstalled both Kaspersky and Firefox.

I have had this problem too, the only fix I had found was remove it off my PC for good.

Sorry. That is my mistake.

Here is the solution from Kaspersky.

"Please find our experts' response to your query below:
Looks similar to bug 7510936.
---
09:37:32.097 53130 INF trafmon ProxySession(988): Client data receive stopped 0x80000063 (Not ready)
09:37:32.097 53130 DBG si.cr InterceptedConnection(988) Request to close connection on behalf of client
---
Developers believe the issue is connected with Firefox feature DOH - "DNS over HTTPS".
Please disable DOH, it should help fix the problem."

So, I disabled DOH in Firefox and in kaspersky settings I checked on "check secure connections (HTTPS) for safe..."

And the problem returned.  I am waiting for the solution.

Hi

I had a similar issue where my browser refused to load certain local sites but others worked fine. I had to uninstall Kaspersky VPN software. It turns out it is still blocking traffic even if its off. Your issue sounds different though. I am about to submit a support ticket for my issue.
