We recently learned that the way Mozilla Firefox stores cached data may have resulted in non-public information being inadvertently stored in the browser’s cache. This means that if you accessed Twitter from a shared or public computer via Mozilla Firefox and took actions like downloading your Twitter data archive or sending or receiving media via Direct Message, this information may have been stored in the browserâs cache even after you logged out of Twitter. The Mozilla Firefox browserâs cache retention period is set to 7 days and after that time the information should have automatically been removed from the cache. This issue did not impact people using other browsers like Safari or Chrome.
We have implemented a change on our end so that going forward the Firefox browser cache will no longer store your personal information. If you use, or have used, a public or shared computer to access Twitter, we encourage you to clear the browser cache before logging out, and to be cautious about the personal information you download on a computer that other people use.
Weâre very sorry this happened. We recognize and appreciate the trust you place in us, and are committed to earning that trust every day. If you have any questions or concerns regarding this incident, you can contact Twitterâs Data Protection Officer by completing the online form located here.

Twitter Data Cache Update: 8 AM (3 April 2020)
When EMEA Tribune asks Mozilla Firefox about this, here is the response we received and clarification from Mozilla.
We are looking into this, your cache data stays on your device
Here is the detailed response from Mozilla Firefox,
Hi! Weâre looking into this Twitter bug right now, but rest assured that when you use Firefox, your cached data stays on your device. So IF the data stayed in your cache, it would only have been viewable on that device. -LH
