When I open Firefox I have the availability to restore the previous session. But before I can click this, my browser is directed to http://a-youtubedownloader-free.com and keeps refreshing until I get the error message 414 Request-URI too large. I'm not sure how to remove this as it is very annoying because I then lose all availability to my previous session. Please help. Thanks in advance.

hello, please try this: go to the firefox menu ≡ > help ? > troubleshooting information > profile folder - "show folder", then a new window will open up. in this window look out for a file named user.js (it might be used to overwrite your custom settings). in case it is present , delete or rename this file and restart firefox.

afterwards install the search reset addon - it will revert the most common customizations those adware programs do in firefox back to the default: https://addons.mozilla.org/firefox/addon/searchreset/

This issue can be caused by corrupted cookies or cookies that are blocked.

  • check the permissions on the about:permissions page and in "Tools > Page Info > Permissions"

Clear the cache and remove cookies only from websites that cause problems.

"Clear the Cache":

  • Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

  • Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

This worked initially but now this attack is back again. The file user.js is not in the folder do now I'm not sure what the problem is or how to solve it. Again, any help would be greatly appreciated.

You could try disabling/removing your VDownloader browser plug-in.
