I want to add

manifest.browser_specific_settings

only to Firefox, and

manifest.developer

only to Firefox and Opera; how do I do so?

Would "manifest.firefox" works in this case? Or can you use author instead of developer?

> Are there any keys that need to be removed for certain platform? They don't "need" to be removed, but considering that the framework aims for simplicity, I'd expect to have such a feature FYI, on non-Firefox the

browser_specific_settings

is given as a warning, as for

developer

, it's given as a warning for Chrome/Edge

> Would "manifest.firefox" works in this case? Let's put it that way:

browser_specific_settings

can receive values

gecko

,

edge

,

safari

according to https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/browser_specific_settings So, if I specify

gecko

, I'd expect the non-Firefox manifest to not have

browser_specific_settings

Suppose I specify

opera

as well, I'd expect Opera to only have

browser_specific_settings.opera

and Firefox to only have

browser_specific_settings.gecko

The same applies for Safari

> Or can you use author instead of developer? Technically I can, but using

developer

lets me use a homepage URL on Firefox & Opera https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/developer

which will interopt with the package.json's

homepage

property
