Title:
Firefox hangs, unable to reload tabs for up to 2min after switching to
session that was idle for several hours
Status in firefox package in Ubuntu:
Expired
Bug description:
I am not sure when exactly this started. I feel like it was around FF
v99.
System is always on. 2 user accounts (mine, wife's). We keep the
desktop sessions logged-in, just switch between accounts whenever
needed. Firefox stays open since it's heavily used. When an active
session is unlocked or switched to after being unused for several
hours (not rigorously measured but I'd say more than 6-8 hours), we
observe the following behavior in Firefox:
* Gmail tab will show a message at the top of the page along the lines of
"Not connected, retrying in 3:00" with the timer counting down
* For the first 10-20s, clicking on another tab will have no effect - FF
doesn't switch to the tab
* From 20s to between 1-2 minutes:
- Switching tabs will work albeit slowly.
- Reloading an existing tab does nothing except cause the side-to-side
loading indicator on the tab to cycle
- I am able to open a new tab via ctrl-T
- I can enter a URL into a new tab, but the site doesn't load. The loading
indicator cycles in the tab title.
- I cannot open about:performance to troubleshoot
After some period of time, as short as 30-40s and as long as 2
minutes, FF becomes usable again. Sites can be loaded/reloaded, etc.
What I have tried, but has not resolved the issue:
* Restart FF in troubleshooting mode
* Upgrade to new releases as they are available in the package manager
* Run in non-troubleshooting mode but with all extensions removed
* Refresh the browser
* Set browser.tabs.unloadOnLowMemory = false
* rm -rf ~/.mozilla and start with a fresh profile
Workaround: killall -9 firefox, then relaunch firefox
Again, this seems to have started suddenly at some point possibly
around the v99 timeframe. Prior to that, I did not observe this
problem. Hardware, and to the best of my knowledge the usage habits of
the 2 users, have not changed in quite some time.
I've attached the output of a "vmstat 1" command that I launched when
I unlocked a session that was idle for approximately 40h, before
interacting with the existing firefox session. The firefox issue
manifested for about 1min 20s. Once firefox became usable, I stopped
the vmstat command.
