Firefox compatibility issues

[warren-bank]

Firefox and Fenix:

1. chrome.extension.getBackgroundPage
   • API returns null when used in Private Browsing mode
2. chrome.storage.local.getBytesInUse
   • API is not available

Fenix:

1. chrome.windows.getAll
   • API is not available
2. chrome.windows.create
   • API is not available
   • related bug report(s)
     • 1372178

test environment:

• addon v1.2.7
• Firefox (desktop) v115
• Fenix (Android) Nightly v122 from 12/11/2023

gist:

• Polyfill for the missing browser.windows API in the Firefox for Android
• file: firefox_for_android.polyfill.ts
  • original
  • mirror

[warren-bank]

upon inspection, the aforementioned polyfill is actually inadequate.

progress..

• I wrote a small addon to inspect the results from the API: chrome.windows.getAll
• I wrote a small addon to inspect the results from the API: chrome.tabs.query
• I wrote a small addon that includes a polyfill that I wrote.. to emulate chrome.windows.getAll using chrome.tabs.query
  • which is successfully tested in Fenix

update..

• v1.2.8
  • solves the 2x issues that affect desktop Firefox (in addition to Fenix)
  • this leaves the 2x issues that only affect Fenix,
    and result from the lack of any chrome.windows.* APIs
  • chrome.windows.getAll can be emulated with a polyfill
  • chrome.windows.create is the roadblock
