Look more like a real extension.
The code is now in a component, not a browser overlay. I followed some instructions from https://developer.mozilla.org/en-US/docs/How_to_Build_an_XPCOM_Component_in_... https://developer.mozilla.org/en-US/docs/Mozilla/XPCOM/Receiving_startup_not... https://developer.mozilla.org/en-US/docs/Mozilla/JavaScript_code_modules/XPC... It now runs just once at startup. (Previously it ran for each new browser window.) --- firefox/chrome.manifest | 7 +++-- firefox/chrome/content/main.js | 47 ----------------------------- firefox/chrome/content/main.xul | 5 ---- firefox/components/main.js | 63 +++++++++++++++++++++++++++++++++++++++ 4 files changed, 68 insertions(+), 54 deletions(-)
