Firefox: Prepare for non-persistent background page #2969
Description
Description
Admittedly, I am a bit late at this.
See:
- https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Background_scripts#convert_to_non-persistent
- https://discourse.mozilla.org/t/is-non-persistent-background-script-mandatory-for-android/123839
To do:
- Verify and fix as needed that auxiliary pages are behaving properly when the uBO background page is terminated
- Evaluate how port closing affects content scripts -- this might be the most problematic aspect of being non-persistent
- This means the generic cosmetic filtering surveyor may be interrupted even though there still could be matching generic cosmetic filters to come
- Optimize timing to generate a selfie, which will be even more key to quickly load back uBO's process into memory
- Evaluate using
storage.sessionto further speed up load sequence

I think this is causing a bug on Firefox for Android. On restoring an old browser session from cold start, uBO appears to need several seconds per tab, one tab at a time to reload state. This results in unusable startup delays with 10+ tabs.

Firefox Android has improved performance on this but the issue remains: ~5s to load ~10 tabs on a recent flagship device after "force stopping" the app.
