This shows a number of timers that should be possible to remove once the http connections are all resolved.
This can reduce power usage in idle cases (especially on mobile, but also probably laptops).

This would fall into the performance and tech-debt categories

Here is a profile where the 'AddTimer' markers have stacks for the 'nsHttpConnectionMgr' timers: https://share.firefox.dev/3ZVF67x

Likely we'll need to retain one timer to close the socket after <whenever>

I can't see anything here hinting about meaningful performance impact. Clearing the flag

Performance Impact: ? → ---

ok, perhaps impact: low. The calculator isn't really good with this kinds of issues.
