[Bug]: Code in develop branch showing white screen and failing to run after build and install

[chirag64]

Describe the bug

I am trying to build and run the MetaMask extension on my Firefox browser, but after loading it in Firefox, it just shows a white screen. On using the browser's Inspect option, I keep getting the console errors: 'Uncaught ReferenceError: LavaPack is not defined'

Steps to reproduce

1. git clone the repository: https://github.com/MetaMask/metamask-extension and checkout the branch develop
2. Run yarn setup
3. Run yarn start
4. After the build starts showing messages .js files being reloaded, open Firefox and go to about:debugging#addons. Click the Load Temporary Add-on... and select the file metamask-extension/dist/firefox/manifest.json
5. Once the MetaMask addon shows up in the Firefox toolbar, click it to open and use it

Error messages or log output

Uncaught ReferenceError: LavaPack is not defined

@chirag64 @ForestTigerKing did you try to reload the extension manually from the Chrome/firefox extension store and eventually remove it and reinstall it?

[chirag64]

@Gtonizuka in my case, the firefox extension from the firefox extension store works just fine. But after i remove it and try to install/load the extension from the develop branch, I am able to reproduce the above issue

I was able to reproduce this same issue today on my Google Chrome browser as well

What if I'm getting this on production version of metamask?

Google Chrome - Version 122.0.6255.0 (Official Build) canary (x86_64)
