Troubleshooting ‘Corrupted Content’ Error on Windows 10

There are several ways to access your Gmail account. You can use the mobile app, open it from your desktop email client, or access the web version. However, some users complain that they encounter a “Corrupted Content Error” when trying to open Gmail through a browser.

Fortunately, if this is the case for you, there are some very effective ways to solve this problem.

What causes the ‘Corrupted Content Error’?

  • In most cases, this problem is due to a partial breach of employee service. If this is the case, the solution is very simple – just unregister your Firefox browser and you can fix the problem.
  • Other possible culprits have corrupted Gmail cookies/caches or a Firefox bug that has been fixed in recent versions.
  • Recently, however, the problem may be due to a recent Mozilla policy change that makes Firefox wary of public networks. In this case, you can fix the problem by changing your network profile to public.
