Firefox build discouraged?

Hi
Thanks for your tool. I work with Firefox and tried to build the extension. I get the following result:

`npm install --global web-ext`

`npm warn deprecated inflight@1.0.6: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.`

`npm warn deprecated @humanwhocodes/config-array@0.13.0: Use @eslint/config-array instead`

`npm warn deprecated rimraf@3.0.2: Rimraf versions prior to v4 are no longer supported`

`npm warn deprecated @humanwhocodes/object-schema@2.0.3: Use @eslint/object-schema instead`

`npm warn deprecated glob@7.2.3: Glob versions prior to v9 are no longer supported`

`npm warn deprecated eslint@8.57.1: This version is no longer supported. Please see https://eslint.org/version-support for other options.`

This looks not very encouraging.
Are there other ways to build the extension or is it doomed for Firefox?
Thanks for your help!
cheers

先檢視 Firefox 擴充功能的建置流程，以及報告中顯示的 `npm install --global web-ext` 命令。確認棄用警告是否會影響建置，或只影響工具相依性；完成標準是記錄受支援的 Firefox 建置路徑，或找出可重現的建置失敗。
