[BUG] Uncaught ReferenceError in Firefox with v5.0.13

[the-nerbs]

Describe the bug
Altair 5.0.13 from the npm package does not load in Firefox.

To Reproduce

1. Open Firefox and navigate to https://altair-gql.sirmuel.design/
2. Observe the Altair logo is displayed, but the client IDE does not load.
3. Open the developer console, and observe that an error is logged:

   Uncaught ReferenceError: chrome is not defined
       45147 https://altair-gql.sirmuel.design/main.js:1
       r https://altair-gql.sirmuel.design/runtime.js:1
       <anonymous> https://altair-gql.sirmuel.design/main.js:1
       n https://altair-gql.sirmuel.design/runtime.js:1
       <anonymous> https://altair-gql.sirmuel.design/main.js:1
       45147 https://altair-gql.sirmuel.design/main.js:1
       r https://altair-gql.sirmuel.design/runtime.js:1
       <anonymous> https://altair-gql.sirmuel.design/main.js:1
       n https://altair-gql.sirmuel.design/runtime.js:1
       n self-hosted:1406
       <anonymous> https://altair-gql.sirmuel.design/main.js:1
   

A second error is also logged (ReferenceError: AltairGraphQL is not defined), but this may just be a consequence of the previous error.

Expected behavior
The Altair client IDE loads without issue.

Screenshots

Desktop:

• OS: Linux Mint 20.3 (through Virtual Box 6.1)
• Browser Firefox 109.0
• Platform: npm package
• Version 5.0.13

Additional context

• Loading the page on Chrome works without any issues, as does the Firefox extension.

• I started seeing this through the graphql-dotnet server's Altair UI package (repo: https://github.com/graphql-dotnet/server) a couple days ago. They load the latest Altair package from jsdelivr (https://cdn.jsdelivr.net/npm/altair-static/build/dist).

• The dev tools point me to the expression !!chrome?.runtime?.id as being what ultimately raises the error. In the diffs against the previous version, I see a change added this expression to packages/altair-app/src/app/modules/altair/utils/index.ts, which seems like a likely culprit:

  - export const isExtension = !!(
  -   (window as any).chrome &&
  -   (window as any).chrome.runtime &&
  -   (window as any).chrome.runtime.id
  - );
  + export const isExtension = !!chrome?.runtime?.id;

  diffs: v5.0.12...v5.0.13#diff-aa95ab08f850063e601922f39c0341abf97355333648539bd4984d211c918461
