On CNN.com i get this error when trying to view video or when clicking on one of their tabs:

400 Bad Request Request Header Or Cookie Too Large nginx

I am using Windows 7, and several months ago my taskbar began disappearing. It will come back if I restart pc, but then disappears again. I know I have gremlins in my pc, but this is ridiculous. Are they serving it for lunch? Really annoying. Can you help? Thanks.

This "Untrusted Connection" thing is god-damned annoying. Websites that I've been using for YEARS... all of a sudden are "untrusted." I don't ***-**** care. How do I turn this feature off?

According to the Adobe Test Page I have installed the Flash Player plug-in successfully but I do not see the Flash Player listed in my plug-ins.

I see Adobe Reader and Adobe Shockwave Flash listed but no Adobe Flash Player.

Why isn't this plug-in showing up?

my Facebook page has shrunk, it is not fullscreen and you cant read it. it's like the whole page fits half of my screen and is so tiny how to I change it back to full view?

The Real Player Browser Download Record Plugin 15.0.1 in Firefox 10 stopped appearing on all videos. It was working from 1/31 to 2/3 and now doesn't show at all. A clean reinstall of Real Player 15 Plus doesn't fix this. OS is Windows 7 Home Premium. As usual after a F.F. upgrade, the download button works on Internet Explorer. Now it's the weekend and Real's Developers aren't even working! The Developers of both companies need to coordinate this once and for all. Norton started doing this with Mozilla at my suggestion for the Norton Tool Bar and there no longer is any delay in compatibility. Please contact Real Player tech support to complain. Their Case Manager told me that the three week compatibility delay with Real Player 14 last year would never happen again. I wouldn't bet on it.

  Update Note: This thread is now also about "Adobe Flash 11.3 doesn't load video content"  because people having that problem started posting here.

Before I upgraded my computer to Windows 7 and updated Firefox to the latest version, when I opened a PDF document online, the PDF navigation/menu bar would automatically appear at the top of the screen. Now it only appears at the bottom in a blue bar when I move my mouse around.

There is a red window that pops up saying certain sites are "attack" sites, and it is super annoying. Supposedly it is another one of Google's brainiac schemes called "safe browsing". I don't want it, it's blocking some of my favourite sites but I can't seem to get rid of it. How do I disable/remove/delete the bleeping thing?

I'm only updating Shockwave Flash because the plugin page says to do it; otherwise I have no problems. The sequence of updating problems I am having is different from that described by others: 1) Checked for plugin updates: Shockwave Flash 11.1 r102 was highlighted as "Vulnerable" with red UPDATE NOW. 2) Clicked on Update Now and was prompted to download Adobe Flash Player 11.1.102.62 (not Shockwave Flash); Ran downloaded .exe file to install; Closed Firefox during install as requested and installation completed. 3) Opened Firefox; Checked plugins and now saw notice that Flash Player version was out-of-date and disabled. 4) As test, played a youtube video; Clicked on prompt at top of screen for "missing plugin"; Update self-executed, requested closing Firefox, and completed installation. 4) Opened Firefox; Checked plugins and once again saw that Shockwave Flash needed UPDATE NOW (as described in #1 above). Adobe Flash Player is not listed anywhere in the plugin list. So now I'm back to where I was before, wondering if I really am vulnerable due to this version of Shockwave Flash.

When I load Mozilla Firefox I get a pop up window in the right hand side of the screen that asks me to install Google Chrome. How can I stop this from appearing. I have Google as my home page, and also have Chrome installed on my comp.

I use Windows7. I can find my favourites (bookmarks) using my explorer like this: computer/c:/user/name/favourites.

When I use Firefox I also save bookmarks. How can I find these in my computer???

I want to make a copy of my bookmarks and paste the copy to another computer this way.

So about 5 days ago this problem started.

I've tried everything, uninstalling, reinstalling, installing older versions of Firefox, everything in the help file about this, going into about:config to set scanning to false, uninstalling my virus program (avast), etc.

They only thing I didn't try is restore points because they didn't go back far enough.

What could this possibly be? The moment the download finished it's absolutely gone.

I'm trying to use a ssl proxy with accounts.google.com.

Usually, firefox warns me about invalid certs, however it let me add an exception if I wanted to connect to it anyway.

But, if i want to connect to accounts.google.com, it blocks me, and it doesn't let me add that exception.

Why it happens only with this subdomain?

I am a web developer. I tried HSTS (HTTP Strict Transport Security) in my developing website.

Now I want to cancel (forget) the HSTS setting for this site, but I cannot. Cannot I access my developing website with HTTP anymore?

I have a young child who uses Firefox. A few years ago I was able to permanently hide the navigation bar to prevent curious browsing (my child is only allowed to use the Bookmarks). I believe I did this through using about:config. Using View->Toolbars->NavigationBar is too easy to figure out. Anyway, my child's computer finally gave up the ghost and I have a new one in which I am trying to child proof. I can't find the appropriate setting in about:config. Can someone help me?

I did install several addons when this appeared. Anyone know from where this right click menu item came? My search suggested "firebug" - whatever that is. This is not on my XP but it is on my Vista and both have the same addons. Thanks
