I just downloaded and ran CCleaner, and now many webpages (including Piriform) do not load properly. The images are not appearing on the websites. I couldn't even sign up for this forum; I had to use Google Chrome to sign up.
You need to give more info.
What operating system and service pack do you run?
What is your default browser?
Did you run with the default ccleaner settings?
Did you do a registry clean, and if you did, did you make a backup when offered the option to do so?
Usually this problem can be solved using the "Clear Browsing Data" (or equivelant) function built into the browser.
My friend had this problem also. Which CCleaner version are you using?
TheWebAtom's suggestion should work. IIRC my friend ran CCleaner again (checked all but saved passwords) while Firefox was closed and that helped.
You should also check from Task Manager that Firefox doesn't run in background; processes like firefox.exe and plugin_container.exe should be closed/ended.
To TheWebAtom,
I tried your suggestion and it worked. Thanks a bunch!
