Kaspersky 2020(e) Firefox 70.0 Hangs

[Tmod700]

I updated to Firefox 70.0 and since the update on initial load FF 70.0 will hang for 30-44 seconds  and then operate as normal. Had to change lockPref("security.enterprise_roots.enabled", true); to lockPref("security.enterprise_roots.enabled", false); in file kl_config_62fbb8f7_c917_4cf7_957a_aad2b8fa768c.cfg.

Is Kapsersky even aware this is an issue?

Firefox may display a TLS connection error when your antivirus software prevents data from being sent to your browser. This happens when your antivirus software fails to register itself with Firefox as a valid issuer of TLS certificates.

Hello  @Tmod700,

1. In KTS, is Windows Certificate Store or Mozilla Certificate Store selected?
2. FireFox, is a Master Password used? 

Please let us know?

Thank you.

If you delete the content of kl_prefs_62fbb8f7_c917_4cf7_957a_aad2b8fa768c.js and then change the attribute to read only so Kaspersky will not write back to it the issue is fixed.

Kaspersky locks the lockPref("security.enterprise_roots.enabled", true); in about:config so Firefox is not able to change it to address the issue.

Oh I should add that this applies to when you have a https site as your home page so the first loaded would be https and then after you wait anywhere from 30-45 seconds to load anything after that will load normally.
