- Extra cleaning for Chromium or Mozilla-based web browsers
- Supported Chromium of Mozilla-based browsers

Extra cleaning for Chromium or Mozilla-based web browsers:
CCleaner lists different web browsers in the Windows and Applications tabs in Custom Clean, but it can clean more than these listed browsers. During the process for Custom Clean > Analyze, CCleaner searches folders on your computer for the data created by these browsers. See CCleaner's supported browsers below.
Supported Chromium or Mozilla-based browsers:
Mozilla-based (based on the Firefox open-source platform)
- Comodo IceDragon
- Pale Moon
Chromium-based (based on the Chromium open-source platform)
- Baidu Spark
- Comodo Dragon
Note: Browsers (based on Mozilla or Chromium) sometimes have their own locations or structures within the folders on your computer. CCleaner only cleans data from browsers that use the same folder structure as Mozilla Firefox or Google Chrome.
Important information about how CCleaner cleans browsers:
The browsers listed above plus any extra browsers you might want to add all get cleaned using CCleaner's Chromium and Mozilla cleaning options. These options even appear if an associated program isn't installed on your computer. For example, if you have SeaMonkey installed (but not Mozilla Firefox), CCleaner displays the Mozilla Firefox cleaning options (and cleans using these options).
Cleaning the profile information for Chromium or Mozilla-based browsers:
Method #1: Clean profile information using the CustomLocation entry in ccleaner.ini
You can enter as many locations for CCleaner to clean as you like in the Options section of ccleaner.ini, but they must be in the following format:
Where X is a whole number starting at 1 and going upwards.
Here is an example which specifies two Mozilla-based browser locations for cleaning:
- The location entries must start at 1 and proceed (sequentially) upwards.
- The folder path is case-insensitive.
- You must use the term "FIREFOX" or "CHROME", followed by the pipe symbol and the folder path.
Method #2: Clean profile information using the Registry
You can add entries to the Windows Registry that CCleaner uses when cleaning custom Mozilla browser profiles. To add Registry entries that are the equivalent of the CustomLocation2 entry shown above, take the following steps:
- Run the Registry Editor (REGEDIT.EXE) from a command prompt.
- Navigate to HKEY_CURRENT_USER\Software\Piriform\CCleaner.
- Right-click the CCleaner node and click New, then click String Value.
- Type CustomLocationX where X is a unique positive whole number (1,2,3 and so on).
- Double-click the CustomLocationX key. The Edit String box appears.
- Type the location in the Value data: text box. For example, the location could be CHROME|C:\Users\<user_name>\AppData\Local\falkon\profiles\default\
- Click OK.
