What does this mean & sa = U & ei?

I have a website, today, looking through the journal, I found a page request from my server with the &sa=U&ei variable added.

Could you tell me guys what & sa = U & e can mean? Maybe trying to find Nullable Scrips? Could there be a security risk?

 &sa=U&ei=XuRBT92UFseYhQf_w7HeBQ&ved=0CNYBEBYwYw&sig2=Rt1Cr_FCPD1-6VYu__Oavg&usg=AFQjCNFlHVaDQL--kgDbOn2vNgUqwUOsTA

Error in my log:

The potentially dangerous Request.Path value was detected by the client (&)

But it doesn’t matter. I found a criminal. It seems that for some, the reason my "GoogleEnhancer" has become "incompatible" with Firefox. This worked even before I upgraded to 10, but go figure. And that wasn’t all this add-on, it was a “Use Google Classic” switch on. I got this add-on after Google started building its search engine like that ... oh, what word I'm looking for ... umm ... oh, yes ... crappy!

I realized what it is ... I have an add-on called google enhancer which, obviously, has not been updated properly recently. Disconnected it and it worked fine. It was a waste. Thanks for the help though guys.

Thus, the unnecessary part of the request is created by an outdated add-in for Firefox, nothing serious. Visitors with this add-on have more problems than your site :)

In practice, it could just be a simple URL request.

And the random texts that you see may be an auto-generated random string for conducting sessions. Since there is nothing wrong with the URL, and those sa and ei just mean that these get variables are assigned some values, which will then be used in your application, as this could be session management or other purposes.

From his face, this does not seem to be hacker material.
