Sound recording

Ways to record

Microphone: capture your speaking or other outside sound from your microphone or sound from any audio-out terminal plugged into Microphone port (but lower recording quality than plugged into Line In port).
Line In: capture sound from any audio-out terminal plugged into Line In port, such as from Cassette player, VCR...
Stereo Mix: capture sound from your PC speaker (~ record what you're listening from your PC speaker). This is the easiest way to capture audio streaming from media player or internet. Recording quality is the best of all.
CD Player: capture sound from your CD player.
Mono Out: capture sound from your PC speaker but just Mono sound.

How to record

Use a recorder software to do that. In this tutorial, I recommend Audacity - an opensource audio editor and recorder, simple interface and easy to use.

Download & Install Audacity: Normal version | Portable version.
Download LAME encoder to save MP3 files: Audacity | LAME site | Free-codecs.com
Unzip and copy LAME files to folder \AudacityPortable\App\LAME (for portable Audacity version).
Run Audacity.
Go to Edit menu > Preferences... > tab Audio I/O > Recording section: select Device = Microsoft Sound Mapper - Input và Channels = 2 (Stereo) > OK.
Choose the way to record from Mixer combo box: Stereo Mix, Mono Out, Microphone, CD Player or Line In.
Play your sound.
Click Record button to start recording, Pause to pause/record and Stop to finish recording.
After recording, you can playback, cut, mix, filter... your recording sound.
Export to MP3 file: Go to File menu > Export As MP3...

Other things

For the best quality of recording, adjust some sound settings, such as:

Adjust playback volume, wave volume, channel balance... Mute which is not necessary to reduce noises.
Adjust recording volume, channel balance... Unselect which is not necessary to reduce noises.

All about Firefox cache

View Firefox cache

To view Firefox cache (similar to Internet Explorer Temporary Internet Files):

Type about:cache?device=disk in address bar and Go. (Notes: You will see the Cache Directory but you can't browse it because it's encrypted).
Ctrl+F or press / and type keyword to find. Use F3 to go to next search result, Shift+F3 to go to previous search result.

Another way to browse the cache is to use CacheViewer add-on.

Or if you want to get Media files of the current page:

Go to menu Tools > Page Info > tab Media
Select what you want to get and click Save As... button.

Advanced Cache Config

Type about:config in address bar and Go:

browser.cache.check_doc_frequency
browser.cache.disk.capacity: disk cache size (in KB, 50000 means 50MB)
browser.cache.disk.enable: enable/disable disk cache
browser.cache.disk.parent_directory: disk cache directory, change this to move cache
browser.cache.disk_cache_ssl
browser.cache.memory.enable: enable/disable memory cache

Clear Cache

Go to menu Tools > Clear Private Data...

Refresh Page

To refresh page, you usually use Refresh button or F5 but sometimes browser may retrieve data from local cache instead of getting from server. To get the latest data from server directly, use Ctrl+F5.

Solutions for Folder Options and Windows problems

When your PC is infected by malicious software, some configurations or files are corrupted or missing. Most happen to Folder Options. Here are some solutions:

Show "Hidden files and folders" option: download this reg and click to run it.

What we can do more? Yes, we can fix the problems manually by copying original files from setup CD or cleaned PC to replace infected files; or editing registry, configurations... For serious problems, restore system, reinstall software, reinstall OS...
