Very infrequently, Firefox starts processing all inputs or actions with a ~10s delay
Every few weeks at random I have the same problem: Any action I take on tabs (e.g. close tab, open new one), as well as any typing I perform, only creates the normal effect after around 10s of delay. I can type whole sentences and nothing happens until 10s later the whole sentence starts appearing as if I had just typed it. The hamburger menu and about dialog where not impacted from this delay.
The CPU and memory load shows no signs of being a bottleneck and nothing performance hungry is happening in the rest of the system.
This happened around 2min after startup, after 5h of work, or anywhere in-between.
Workaround is a browser restart, but it is quite annoying if this occurs while I'm filling in a form and I have to start over.
Ubuntu 24.04 - snap package Once the issue occurred, I disabled all extensions (without restart), but the issue continued.
