Clear the cache and the cookies from sites that cause problems.

"Clear the Cache":

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

"Remove Cookies" from sites causing problems:

  • Tools > Options > Privacy > Cookies: "Show Cookies"

Try to delete the webappsstore.sqlite file in the Firefox Profile Folder to clear the current local storage aka 'super cookies'.

You can use this button to go to the Firefox profile folder:

If Firefox is closed then you should only see the cookies.sqlite file and not the other temporary sqlite files.
Deleting that file removes all cookies, so you might want to try to clear cookies from affected domains first.

Did you already tried this and also removed the webappsstore.sqlite file?

Just recieved this from downloadhelper

From version 4.9.9 to 4.9.10

   After some changes in YouTube on September 14th, Video DownloadHelper was not able to download any video from this site, except the WEBM version while using the YouTube HTML5 mode. This is fixed in this addon version.
   After some changes in YouTube on August 6th, a number of users reported that all downloads were failing. This was caused by a a Youtube-generated cookie. The workaround consisting of clearing the cookies before downloading was not very convenient. This addon version takes care of that issue.
   Earlier this year, some other changes at YouTube caused the FLV videos downloaded through the "network" method to have a fixed 1.7MB size and being unplayable. This is now taken care of.

Don't try to open the SQLite file. Only Firefox is able to read the content of that file properly and show the content in the cookie manager.

Just try if it work better if the file is removed.

Are you talking about the cookies.sqlite file?

Yes, you can delete the file if you do not need to restore those cookies.

You seem to have gathered a lot of cookies if the cookies.sqlite file is 2MB.
You might consider changing the cookie settings and disable third-party cookies and let the cookies expire when you close Firefox.
You can set an allow exception if you want to keep cookies from specific websites like special settings or cookies that remember you (keep you logged in for a longer period).

Tried doing all that. Doesn't work. Still getting "0 KB". I think Downloadhelper is incompatible with YouTube now.
