Steps to reproduce:

1. Unzip Archive.zip
2. Enable "extensions.manifestV3.enabled" and "xpinstall.signatures.required" in Firefox Nightly.
3. Attempt to load the "all_urls" extension.

Actual results:

The extension fails to load because <all_urls> does not match the expected RegEx.

Expected results:

It would be great for this to be supported.

The functionality would be the same as both https://*/* and http://*/* which already work today. I've included a "regex" extension which demonstrates this. Load the extension, make sure to give it permission to alter all webpages, and then go to https://example.com/ to see the content script/CSS injected and a red border shown.

Both of these examples work in Chrome.

The Bugbug bot thinks this bug should belong to the 'WebExtensions::Untriaged' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

matches was introduced in bug 1697334, using the MatchPatternRestricted type. It should have been using the MatchPattern type instead (https://searchfox.org/mozilla-central/rev/b7642d0089449244d6361680bc619c94bf11725f/toolkit/components/extensions/schemas/manifest.json#621-649).

For comparison, Chrome does not impose any restrictions on the match pattern format: https://source.chromium.org/chromium/chromium/src/+/main:extensions/common/manifest_handlers/web_accessible_resources_info.cc;l=116-126;drc=5867b3b59ed9c5713477656561a99cc543b9d8c5
