Firefox cannot open certain sites

When I try to log onto a secure website, such as a bank or tax office, when you hit the log on button, firefox opens a new window, not in a tab, with just the address bar at the top saying search bookmarks and history, and goes no further. This has only happened recently, the problem does not occur in safari.

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

Why doesnt java work with firefox,i cannot open certain sites

The message about CVE-2009-3555 is meant for webmasters to make them aware that they need to fix their servers. 
Firefox 3.6 versions can detect such a misconfiguration and displays a warning in the "Tools > Error Console".

Cannot open certain sites properly

cannot build a vehicle on ford website
cannot use kawartha pine ridge website
have problems on john deere site as well when logged in as a dealer

Without seeing the URL's, I can only guess the sites you listed are not Safari-friendly. Usually, when Safari does not cooperate, I switch to either Firefox or Camino browsers. Might want to give either a try.

Firefox cannot open any web site except facebook

firefox cannot open any web site except facebook.when i browse other site except facebook, it automatically open facebook.

Does Blackberry Link install any add-ons into Firefox? You can check here:
orange Firefox button (or Tools menu) > Add-ons > Plugins category 
orange Firefox button (or Tools menu) > Add-ons > Extensions category
Also, does Blackberry Link create any Windows network connections? To make sure Firefox isn't randomly choosing dysfunctional networks, check your proxy setting here:
orange Firefox button (or Tools menu) > Options > Advanced > Network > "Settings" button
If you have Auto-detect, try either No Proxy or Use system proxy settings.

Cannot open certain messages in Messenger Express

Sun Java(tm) System Messaging Server 6.3-5.02 (built Oct 12 2007; 32bit)
libimta.so 6.3-5.02 (built 17:15:31, Oct 12 2007; 32bit)
SunOS f3 5.10 Generic_125100-10 sun4u sparc SUNW,
We have a user who cannot open certain sent messages - I reconstructed her mailbox to no avail - I also copied the messages to my mailbox and reconstructed, I also couldn't open them.
Once one of the problem msgs is clicked, every message becomes unreadable, it seems to break the javascript function (javascript:parent.M(n)) which is responsible for popping up msg windows for reading.
Re-logging in, or a refresh fixes. Until one is clicked again.
My Firebug debugger shows:
an "unterminated literal string" error and references this for example:
'Dear Mr. Smith: \nHere are some of the content encoding headers from two msgs. One of these had a Word doc attached, one doesn't seem to have any attachments.

Two things though the problem msgs do have in common are strange encoding in the body e.g.:

Thanks for clarifying on the encoding vs charset and for the other reference in these forums.
The client is listed as:
X-Mailer: Sun Java(tm) System Messenger Express 6.3-5.02 (built Oct 12 2007; 32bit)
I was told this particular user used Safari... could that influence the transfer-encoding? Or is ME messing up?
I'm not sure it's possible - but might he have created this in ME from an already received, but messed up message (e.g. one w/ the quoted-printable encoding)? In ME it seems he wouldn't be able to open these for editing.
The X-Mailer header is in the first set of headers,
The second set contains the multi-part - printed quotable and in-line enclosed (as opposed to attached) Word .doc.

Why can't Firefox cannot load certain applications on certain sites like a whole chatroom, video player or the reply box on a forum?

When I was ask to join this site ( the mozilla support site), firefox was unable to display the register or log in page, all i saw was the page getting darker and an unmoving white rectangle.
Also when I got certain site to watch a video like animefreak.com the video player will never appear, I have to use internet explorer to watch it.
There are some sites where the chatroom simply doesn't appear and others where I can't even use the reply box in the forum

Recently both the Yahoo! Toolbar extension and the Babylon extension have been reported to cause an issue like that. Disable or uninstall those add-ons.

Hello kadur778, if you cannot open websites that needs login (username and password) like Gmail or Facebook then delete the cookies.sqlite file and any cookies.sqlite-journal files in [http://kb.mozillazine.org/Profile_folder_-_Firefox#Windows profile folder] and restart firefox.
see for more info : [https://support.mozilla.org/en-US/kb/fix-login-issues-on-websites-require-passwords#w_remove-corrupt-cookies-file Remove corrupt cookies file]
thank you

Firefox cannot load certain websites and I've tried all suggested options to fix the problem.

I cannot load certain websites (my bank, some public/civic offices, etc.) on Firefox or Internet Explorer (I usually use Firefox) and have tried all the suggested options in Firefox Help to remedy this problem: clearing cache and cookies, making sure no proxy is selected, allowing cookies). How do I fix this? I use a broadband internet connection that is shared.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
 To Enable SafeMode 
*You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
*''Once you get the pop-up, just select "'Start in Safe Mode"''
If it works in Safe Mode and in normal mode with all extensions (Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: "Firefox > Quit Firefox"; Linux: "Firefox/File > Quit")

You can use these steps to check if images are blocked:
*Open the web page that has the images missing in a browser tab.
*Click the website favicon ([[Site Identity Button]]) on the left end of the location bar.
*Click the "More Information" button to open the "Page Info" window with the Security tab selected (also accessible via "Tools > Page Info").
*Go to the Media tab of the "Tools > Page Info" window.
*Select the first image link and scroll down through the list with the Down arrow key.
*If an image in the list is grayed and there is a check-mark in the box "Block Images from..." then remove that mark to unblock the images from that domain.

After updating Firefox, cannot open at all, system tells me Firefox is already running, but it isn't. I can't even remove it from system???

After updating to Firefox 6, I cannot open Firefox at all. Nothing happens when I try. I went to Control Panel and tried to remove Firefox, but my system tells me that Firefox is already running, please close to continue. I do not have another copy running. Everything was working great until this last update.
I have tried all the recommendations on your site but nothing is helping - very frustrating!!!!!

Firefox cannot open pictures in F/B, but Internet Explorer does. Why?

While surfing Facebook.com I was unable to view pictures on any sites I visited while using Firefox 3.6.13. I exited Firefox and opened Internet Explorer 8.0.6+, and all photos opened without any trouble. How can I view pictures on Facebook.com while using Firefox?

It is possible that you clicked "Block Images" in the right-click context menu while saving an image.

Safari Not Opening Certain Sites????

I am encountering some trouble with this new Safari set up. Most recent issue is, tried to open a site on my computer that worked yesterday. Contacted sites webmaster and they told me that Microsoft updated its internet browser and that if I don't have the correct settings on my brower, I will not be able to view the site. They told me to contact my ISP to have them walk me thru fixing the trouble. My ISP, verizon told me that this is not their issue but to contact Apple. I just want to know how I can view my website now? Firefox won't even work on it. It is just my work resume system and it does work at my office via a Microsoft Internet browser, just not with my Safari any more. I don't know what I need to do to fix this. Please help!

Yang, I appreciate the response. I tried your suggestion out and it didn't work. I keep getting this message:
The Web server you are attempting to reach has a list of IP addresses that are not allowed to access the Web site, and the IP address of your browsing computer is on this list.
Your IP address identifies your home network - or whatever network you are using to access the web. (That is, your home modem or router or your work modem or router.) This means that your location has been blocked from accessing this web site. I suppose this could be something automated by the web site you are trying to visit. It can also be done deliberately by the administrator of the web site. (Edit: One thought is that you might have been locked out due to having tried the wrong username and password too many times, or for some similar security issue.)
Trying to access the site via a different web browser isn't likely to change that, since it is your location ("your browsing computer") that is being blocked. The only thing you can do if that message is accurate is contact the IT people who manage your workplace's web site again, this time giving them that error message so they know that this is not a problem with your web browser or the Mac OS - it is a very specific problem due to your IP address being actively blocked by the server where the site is hosted.

Cannot open certain things, it states server not found

when trying to check my status of my federal student financial aid application, i get a message that states firefox cannot find a server
== URL of affected sites ==
http://www.FederalStudentAid.ed.gov

Hello Sandy.
Please check if your antivirus/firewall/security suite isn't blocking Firefox. If it isn't, it's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] (don't forget to select ''Disable all add-ons'' when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and themes and [https://support.mozilla.com/en-US/kb/Troubleshooting+plugins this one] for plugins.
If you need support for one of your add-ons, you'll have to contact its author.
If the problem is not disappears when all add-ons are disabled, please tell me, so we can work from there. Please have no fear of following my instructions to the line, as all can be easily undone.

Safari and Firefox stalling on certain sites

Certain internet sites like the New York Times and ESPN seem to make Safari and Firefox stall completely. Anyone have a solution for this?

Try using the Activity Window when visiting one or two of the problem sites. I found that one site was loading two flash files, each over 1 megabyte. Instead of loading the rest of the site, these files stalled the entire site, or Safari, until they were loaded. In the Error Console I'm seeing lots, more than two dozen on one site, of Javascript errors. Again, I think it's a combination of bad/outdated programming on some sites and something broken in Safari.
I think the issue boils down to sloppy programming on some sites and changes to the recent build of Safari. I don't know if the recent OS upgrade broke Javascript and I wish there were a way to reinstall it alone to see if that fixes part of the problem.
I also notice that with OS 10.5.6 and Firefox that same problem sites are also slower to load, but not nearly as slow as when using Safari. Logging in with Tiger and its version of Safari is definitely a better experience.
