As an open source browser that specializes in security and privacy, Mozilla Firefox has a loyal multi-platform user. However, a recent Twitter vulnerability has cast a shadow over users who use the browser to access social networking sites. Media point out that if you’ve been accessing Twitter through Firefox, you’re likely to have stored nonpublic information data in your local cache.
Fortunately, Twitter says it has fixed the problem on the server side, and neither Google Chrome nor Apple Safari has been affected.
In an interview with Beta News, the social giant said the problem was related to Mozilla’s handling of browser default settings for HTTP header data.
To avoid this problem, Twitter has implemented a change to stop Mozilla Firefox storing Twitter data in the cache.
Twitter, however, didn’t blame Mozilla for mistakes or leaks, so people don’t have to worry about criticizing Firefox.
If you access Twitter from a shared or public computer through Firefox, and you’ve taken things like download ingesting data, or sending and receiving media files through Direct Message.
Then even if you log out, this information may still be stored in the browser’s cache. Firefox defaults to 7 days and is automatically cleaned up after the timeout.
Finally, Twitter said it had implemented a change completely and would no longer store users’ personal information in the Firefox browser cache. Users who are not comfortable with the idea of logging out and cleaning up the cache in a timely manner after using a public computer.
