Hello
It would appear that CCleaner does not remove site specific zoom information. This setting is available in Firefox via the option browser.zoom.siteSpecific in about:config. If you hold down Ctrl you can zoom to make the page larger or smaller with the mouse wheel.
Firefox retains the zoom setting for each individual page. You can turn browser.zoom.siteSpecific to false, but this may not erase data you may have saved already, maybe by inadvertently pressing ctrl+wheel.
This data does not appear to be removed when CCleaner is run. Has anyone else noticed this?
To my knowledge CCleaner has never messed with Firefox's prefs.js file, and really has absolutely no valid reason to ever do so.
I recommend sticking to published information about how to manually "tweak" Firefox.
Andavari I am not suggesting CCleaner should modify Firefox prefs.
When browser.zoom.siteSpecific is set to true in Firefox, which is the default, Firefox retains an individual zoom setting for each individual web page you visit. It must therefore save every web address you have visited in order to retain the zoom setting you have chosen for that web address.
Try it: visit a web site, use ctrl and wheel to select a zoom level, then erase all firefox data with ccleaner. Now return to the website and you will see that your zoom level for that website has been retained. Go to another site and you will see the default zoom level, proving it is not a global zoom setting.
If the point of CCleaner is to erase all details of every page visited, this information should be erased also.
The Zoom Settings information is kept in the following location:
C:\Documents and Settings\<username>\Application Data\Mozilla\Firefox\Profiles\vh45vzuh.default
Bold number will differ.
The file is called "content-prefs.sqlite".
Add that file to CCleaners "Include" feature and that will remove the saved Zoom setting. "CCleaner\Options\Include File or Folder".
Thanks Dennis that's helpful!
I neglected to mention you need "Custom Files And Folders" checked for the "Include" feature to work:
"CCleaner\Windows\Advanced".
