firefox: Update version from 88.0 to 90.0

1.  https://www.mozilla.org/en-US/firefox/89.0/releasenotes/
2.  https://www.mozilla.org/en-US/firefox/90.0/releasenotes/

Firefox 90.0 requires cbindgen 1.19.0, which is present in the Rust
1.52.1 package. So, use this. [Rust 1.53.0 fails to build][1], so it’s
not used.

     "Unable to build 1.53.0 from official tarball due to miri #86436"
