web-ext thinks I am running 32 bit architecture when it is 64 bit

[grandeljay]

I am trying to get a project running via web-ext but get this following error:

$ yarn run manifest:firefox && node_modules/.bin/web-ext run --source-dir dist/extension/
yarn run v1.22.19
$ ts-node scripts/applyManifestOverrides.ts --type=firefox
firefox manifest applied.
Done in 0.23s.

You are using 32-bit version of Firefox on 64-bit versions of the Windows.
Some features may not work correctly in this version. You should upgrade Firefox to the latest 64-bit version now!

I typed navigator.userAgent into the developers console and got:

"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:133.0) Gecko/20100101 Firefox/133.0" 

It seems one of these outputs are wrong.

Do you have any insights or ideas what could be going wrong here and causing this error?

The error message originates from https://github.com/mozilla/node-fx-runner/blob/b31bbca6dbd89f820f3b621c1785e3ddfcc85b1a/lib/utils.js#L79-L86

That code and the preceding code may offer pointers on debugging this issue.

The "arch" is derived from os.arch(). What is the output of node -e 'console.log(require("os").arch())' ?

How did you install Firefox?

$ node -e 'console.log(require("os").arch())'
x64

How did you install Firefox?

I installed it with the ChocolateyGUI but with all default values so I presume the equivelant command I used would be:

choco install librewolf

Sorry I don't work with build or command line tools very much so my knowledge is basic at best. Any chance you could hand feed me some instructions on what I can do to help?

Sorry I should mention that I am running LibreWolf but from my understanding the source code is basically the same:

For me this issue was caused because I use Firefox Developer Edition and it was only looking for the "Mozilla Firefox" regkey. Fixed it by additionally installing default Firefox
