Steps to reproduce:
Boot into windows
Open Firefox
Open any web page
Actual results:
The page is loading for ~3 minutes
When checking the capture created by launching Firefox with MOZ_PROFILER_STARTUP=1, I can observe 85% of startup time under WebExtensions > mozilla::dom::LSObject::GetItem

Expected results:
Loading should not take more than a few seconds (other pages after the first one finished loading behave as expected)

The Bugbug bot thinks this bug should belong to the 'Core::DOM: Core & HTML' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Could this be related to a data migration or archival?
I've had this problem for quite some time now, and only took time to report it now.
I don't remember precisely, but I feel this issue appeared progressively.

Could this be related to a data migration or archival?
It's most likely related to slow temporary storage initialization when there are many origins in combination with slower hardware.
Update on this : this may indeed be related to slow storage hardware. My data are on an aging HDD, and I'm usually not cleaning my history and site data.
Made some cleanup last week, deleting all site data and cache + clearing history older than 6 months, and now the startup time is way faster.
Still, it is a bit weird to not be able to load a webpage until user data has been loaded.
But I guess the issue is solved for now on my side (until data accumulate again, or I switch to faster storage)
