Description Johnray Fuller 2021-12-03 02:02:18 UTC

Description of problem:

This issue with NSS effects Firefox 91.3.0esr (64-bit) and makes the password manager and the browser essentially unusable if you have both a large number of logins saved and a login page open.

The only workaround I have found it so turn off the password manager.

Version-Release number of selected component (if applicable):

nss-3.67.0-4.el7_9.x86_64

with

firefox-91.3.0-1.el7_9.x86_64

How reproducible:

All day, every day.


Steps to Reproduce:
1. Use Firefox password manager with a large number of passwords.
2. Open a Web page with a saved password (access.redhat.com, for instance)
3. Watch all your CPUs peg and wait for multiple minutes for keystrokes to show up after you type them.

Actual results:

Using the Firefox password manager becomes essentially impossible.

Expected results:

Firefox and password manager are usable again.

Additional info:

This is fixed in NSS 3.68 as mentioned in the Mozilla bug here:

https://bugzilla.mozilla.org/show_bug.cgi?id=1729930

Can this fix be backported to nss-3.67 or can we move nss forward to 3.68?
