Yes I would like to know how to delete my youtube history and all history all together

For some strange reason, it seems that 9 out
of 10 error messages like this are with Firefox.

If "your browser sent a request that this server
could not understand", that "request" could be
a bad, false or "overlarge" cookie.

Simply delete all your cookies, and everything
should be fine. Don't worry about getting rid of
them; absolutely nothing bad will happen. The
worst-case scenario is that you'll have to input
your username and password again when you
revisit those websites. That's all.

While you're erasing your cookies, you should
also contemplate deleting all your "temporary
internet files" and "history" to make everything
fresh and new:

Internet Explorer 6:
> Tools > Internet Options
> Delete Cookies > OK
> Delete Files > OK
> Clear History > Yes
> OK

Internet Explorer 7:
> Tools > Internet Options > Delete...
> Delete files > Yes
> Delete cookies > OK
> Delete history > OK
> Close (browsing history window)
> OK

Mozilla Firefox
> Tools > Clear Private Data
(x) Browsing History
(x) Download History
(x) Saved Form and Search History
(x) Cache
(x) Cookies
> Clear Private Data Now

For some very odd reason, it seems that 9 out
of 10 error messages like this deal with Firefox.

If "Your browser sent a request that this server
could not understand", plus "Size of a request
header field exceeds server limit", that strange
request may be a bad or unusually big cookie.
(The same thing is true for "Error 400" codes.)

Simply clear all of your cookies and everything
should be fine. Don't worry about getting rid of
them; absolutely nothing bad will happen. You
won’t lose your internet browser's "Bookmarks"
or "Favorites". The worst-case scenario is that
you will have to type your username/password
again when you first revisit YouTube and a few
other websites -- that's all.

While you're erasing your cookies, you should
also be deleting your "temporary internet files"
and "history" to get them out of your computer
memory, and make everything fresh. After that,
it is probably better if you shutdown and reboot.

Internet Explorer 6:
→ Tools → Internet Options
→ Delete Cookies → OK
→ Delete Files → OK
→ Clear History → Yes
→ OK

Internet Explorer 7:
→ Tools → Internet Options → Delete...
→ Delete files → Yes
→ Delete cookies → OK
→ Delete history → OK
→ Close (browsing history window)
→ OK

Mozilla Firefox
→ Tools → Clear Private Data
[x] Browsing History
[x] Download History
[x] Saved Form and Search History
[x] Cache
[x] Cookies
→ Clear Private Data Now

If "your browser sent a request that this server could not understand"
and "size of request header field exceeds server limit", your request
is a bad or oversized cookie. (The same thing is true for "Error 400").

For some very strange reason, it seems 9 of
10 Bad Request messages implicate Firefox.

Simply delete your "Cookies" and everything
will be okay. Don't worry about erasing them;
nothing bad will happen. You won't lose your
internet browser's "Bookmarks" or "Favorites".
The worst thing that could happen is you will
be asked to retype your username/password
when you return to YouTube and some other
websites -- that's all.

As you're dumping your cookies, you should
also erase all your "Temporary Internet Files"
and "History". This will render your computer
totally "fresh" in YouTube's eyes. It would be
best if you shutdown / reboot after doing this:

Internet Explorer 6:
> Tools > Internet Options
> Delete Cookies > OK
> Delete Files > OK
> Clear History > Yes
> OK

Internet Explorer 7:
> Tools > Internet Options > Delete...
> Delete files > Yes
> Delete cookies > OK
> Delete history > OK
> Close (browsing history window)
> OK

Hi,

If we talk about 400 bad request error, read the meaning of the same :-

http://www.checkupdown.com/status/E400.html

There might be several reasons :-

1. There server is down at the time when you try to access youtube.
2. Your internet browser might be at fault.
3. Your internet connection might be at fault.
4. Miscellaneous etc.

Now, as you informed me that you are unable to view youtube. Is that always or sometimes?

If everytime, there is an issue from your end.

Try to remove cookies from your browser. Go to tools on the top of our browser>Internet connection

You need to remove all the cookies and then restart your system and check.

Hi there!

If "your browser sent a request that this server
could not understand" - and "size of a request
header field exceeds server limit", that strange
request may be a bad or "super-sized" cookie.

Simply delete all your cookies, and everything
should be fine.

While you're erasing your cookies, you should
also be deleting your "temporary internet files"
and "history" to make everything fresh.

Here's how:

Internet Explorer 6:
→ Tools → Internet Options
→ Delete Cookies → OK
→ Delete Files → OK
→ Clear History → Yes
→ OK

Internet Explorer 7:
→ Tools → Internet Options → Delete...
→ Delete files → Yes
→ Delete cookies → OK
→ Delete history → OK
→ Close (browsing history window)
→ OK

Mozilla Firefox
→ Tools → Clear Private Data
[x] Browsing History
[x] Download History
[x] Saved Form and Search History
[x] Cache
[x] Cookies
→ Clear Private Data Now

Have fun!
