I recently upgraded to Oneiric and noticed that the calendar is no longer persistent like it was in Natty and Maverick. I could open the calendar to January 2007, then move to another window and still refer to the calendar. Now, as soon as I lose focus the calendar goes back into hiding. Is this a setting somewhere?

Temporarily downloaded files
----------------------------

All Linux browsers (including Firefox and Chrome) store "Open for viewing" downloads in the `/tmp` directory. Old `/tmp` files are deleted the following situations:

1. When you close your browser
2. When you restart Ubuntu
3. When your disk space is low

If you want to make a temporary download permanent, you can simply navigate to `/tmp`, find the file in question, and copy it into your home folder.

Streaming media
---------------

Flash, audio, and video files you play are cached in highly obfuscated directories like `$HOME/.mozilla/firefox/3lms8ke.default/C/2A` for Firefox. Woozie's answer to [this question](https://askubuntu.com/q/37267/24694) can help you find and retrieve flash files. Remove the `| grep Flash` part of his command to get a list of all cached files by their data type.
do you mean : "the browser cache

take a look at :

```
/home/$USER/.mozilla/firefox/SOMETHIN.default/Cache

```
