User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:85.0) Gecko/20100101 Firefox/85.0

Steps to reproduce:

about:logins

Actual results:

for about 1200 credentials it takes a while for the page and list to populate. There is no indication that the list of logins is being put together for display on the page. On a slower computer it can take about a minute and it makes it appear that FireFox has frozen loading the logins credentials management page.

Expected results:

When about:logins is invoked, there should be an indication that the page is loading and being populated with login credentials. Something like a percent indication would be useful.

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

This sounds like the same root cause as bug 1658766? In that bug we found that on Windows, some users/profiles are taking a long time to decrypt the logins. Regardless of the cause, I think I agree that we should indicate what is going on to the user.

Yes. I agree. It does look like it is. Normal install of FF on my laptop.

CPU is Intel64 Family 6 Model 158 Stepping 9 GenuineIntel ~2808 Mhz. Laptop clocks it at a maximum of 3520 Mhz. CPU performance configuration is baked into the BIOS by manufacturer. Laptop has no over-clocking settings.
