Wait... What? Firefox blocks my access to GitHub?

To reproduce:

  1. Open Firefox and go to https://github.com/conda-forge/miniforge
  2. Click on the "Mamba" link in top of the README, which is simply an innocent link to another GitHub repo.

  1. Trigger "Go back" of the browser, and boom.

I am using Firefox Developer Edition 134.0b10 (for Arch Linux).

Update: Seems that this issue has nothing to do with Firefox, it is Google Safe Browsing that strangely marks the specific url (repo link + "?tab=readme-ov-file") as unsafe.
