Can you suggest a good extension for this?
Welcome to the forums, @rahulsheoran485.
Can you explain exactly what it is you’re trying to do, and how it relates to SEO? Cache and cookies can be cleared from the browser. In Firefox, the option is under “Settings”.
Are you using a website builder such as WordPress or Wix? Could you please provide more context for your question?
Click&Clean chrome extension is good for cash-clean. I have using for the last 3 years.
Don’t mean to be rude, but I really don’t want something that clears my cash. Cache yes, though!
