Can manifest.json be checked/debugged in dev tools?
Chrome dev tools have a tab labeled "Application" here you can view the manifest.json of a PWA and determine if it is installable or if there is a problem with it.
Can this feature be added to the dev tools in Firefox? Especially with so much of the web already being developed for PWA's rather than native apps, it would be a big help in debugging this file without using Chrome.

You can check a manifest.json file via the about:debugging page.
about:debugging has the ability to debug Add-ons, Tabs and Workers (service workers) and in Firefox Dev we can do temporary extensions, extensions, service workers, shared workers and other workers... Nowhere could I find anything related to manifest.json in these browsers.
I don't think Firefox supports PWA's yet on desktop OSes. Or was that added recently?
The Dev Tools team has its own forum over here if you have questions or want to suggest new features specifically for dev tools:
jscher2000,
It isn't about desktop PWA's. Simply about being able to inspect the manifest.json within the developer tools while developing a PWA. Results simply parse the file and display icons, etc. and informs if it meets standards to be installed on a mobile device as a PWA. Just a handy convenience....
I knew we could inspect extension manifest files using about:debugging.
Example of the benefit was the manifest was considered invalid in both Chrome and Safari because of comments in a json file, while Android would accept it and install just fine...
Thanks for your answer and I will add it to the dev tools as a feature request...
Hi,
the equivalent of "Application" for Chrome in the manifest.json file
is for Firefox
for Firefox
I'm thinking of an idea that is to create your own devtools panel in the form of a web extension
I share with you an example I created
and the documentation MDN WebExtensions
best regard
