[Work] firefox, mozilla locked!
In Firefox 1.5 or later, a "Close Firefox" dialog box may appear with one of these messages:
"Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system."
How to unlock your profile
Your profile may be inaccessible for a number of reasons, most often because the application failed to shut down completely the last time it was used and the task or process is still "running in the background", even though there are no open application windows. Ending the running process is normally sufficient to unlock the profile. If the profile remains inaccessible, try these other solutions:
[edit]
End processes
Go through your task or process list to see if multiple instances of Firefox, Thunderbird or Mozilla Suite are still running or not responding and end each instance found.
[edit]
Remove the profile lock file
The application may have shut down abnormally, leaving the lock in place. To fix this, open the profile folder and delete the file,
* "parent.lock" (Windows),
* "lock" and ".parentlock" (Linux), or
* ".parentlock" (Mac OS X)

[Wor] lithium ion battery
When to recharge
You can recharge a lithium ion battery pack whenever it is convenient. Unlike a conventional battery pack, it does not have to be fully discharged first. However, as the battery pack will natually discharge itself over time, it is best to charge it the smae day you plan to use it, or the day before.
In addition, there is the possibility of damage to the battery pack and reduced usage time if fully charged batteries are stored for a period of months.
Disconnect the battery pack when you are not using it.
Even when it is turned off, the product the battery pack is attached to will continue to slowly drain power from the battery pack.
When you plan to store a battery pack aim to use its complete charge first, before disconneting it. Store the battery in an area which is free of moisture, and where the temperature is no higher than 30C.
