The GitHub community is aware of this problem.
As the person quoted:
“If the Bitwarden extension cannot reach its servers when launching Firefox, internally it does not handle this issue gracefully. Externally, I don’t see a problem”.
I also get these messages constantly (100+ every 10 minutes):
Everything is working but I suspect Bitwarden is draining more CPU power than necessary. It annoys me because this problem has persisted for longer than a year. I haven’t seen any threads about this issue in the community so it might be that the problem is unnoticed so far.
What I’ve tried so far:
- deactivating all other add-ons; the errors persists.
- deactivating Bitwarden Add-on; the errors subside.
