Firefox cannot load sites as: Facebook, Twitter and Hyves

Other websites can be load. Only social network sites like Facebook, Twitter and Hyves does not load. But safari does not load at all. So maybe it is my Macbook Pro that is failing.

Hi syazita
Check to be sure your anti-virus is allowing. But the fact that you can't clear cookies makes me think Malware maybe involved. I would run an Malware scan to be sure.

Firefox is not keeping me "logged in" on certain sites like Facebook, Twitter, and Netflix.

Every time I open Firefox and go on Facebook I have to log in. I am on a private desktop so I am not worried about other users. This goes for everything: Facebook, Twitter, Yahoo Mail and other sites.

Alright, well again I was able to resolve this on my own. Not sure how though.
I started accepting the "Do you want to store this password..." requests and they started to stick finally. Facebook stays logged in now, even after quitting Safari. I've just upgraded to 10.5.8 and Safari 4.03, everything seems to be fine (knock wood). Marking this SOLVED for now.

I just downloaded the new version of Firefox and now every site I used to use such as Facebook, Twitter, and Youtube show "This Connection Is Untrusted"

I just downloaded the new version of Firefox and now every site I used to use such as Facebook, Twitter, and Youtube show "This Connection Is Untrusted". Even when I do accept the risks the site no longer looks the way it's looked for years. Twitter doesn't even give me the option to accept the risks at all and shows this error (Error code: sec_error_unknown_issuer). I've tried resetting Firefox, I've checked the time and date, and I've removed and added Firefox to see if that would work. Nothing seems to be working so I can see the sites the way they normally would be instead of "coded". Can anybody help me please?!!! Thanks

ok, unfortunately the fiddler2.com issuer in certificates might be a sign of unwanted software present on your pc that is intercepting secure network traffic. please go into the system control panel and uninstall programs like BrowserSafeguard, BrowserSafe, SafeGuard or other software that sounds suspicious and didn't get installed by you intentionally.
reference: https://support.mozilla.org/en-US/questions/982532#answer-520145
afterwards, run a full scan of your system with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] & [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner].

A good place to ask advice about web development is at the mozillaZine Web Development/Standards Evangelism forum. 
The helpers at that forum are more knowledgeable about web development issues.

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
See:

You can try to reset (power off/on) the router.

HT3964 power outage seems to have upset macbook pro....says security certificates aren't valid for sites like facebook, google, and apple app site...cannot connect to app store to update

Hi k,
I don't know if it's the same in your OS, but in 10.6.8:
Go to Applications > Utilities > Keychain Access > Keychain Access menu > Keychain First Aid > enter your password > click on Verify > click on Start. If you get a message saying something needs to be repaired, click on Repair > Start and wait for it to finish.

Firefox cannot load all websites in e10s window. But Firefox can load all websites in e10s window.

Firefox cannot load all websites in e10s window. But Firefox can load all websites in e10s window.
It shows mostly, Tab crashed Well, this is embarrassing.
Well, this is embarrassing. We tried to display this Web page, but it's not responding.
Tell Mozilla about this crash so they can fix it.
Or sometimes for the last tab it shows :
Websites show a spinning wheel and never finish loading
Of course other browsers works 'perfectly' onto loading sites.
What can I do. Is this an e10s bug, that I could help to qualify and how?
Also looking for a workaroud. I want to restore my tabs onto a non-e10s window, but really don't figure how to do that. Means, after relaunching FF-nightly, restore my windows and tabs.
He still give me this message :
Nightly is having trouble recovering your windows and tabs. blah blah...
I want to disable e10s as of for now, until he will maybe work again.

If you would like to disable e10s please follow these steps:
https://wiki.mozilla.org/Electrolysis#Enabling_and_Disabling_Electrolysis
Don't worry e10s is getting better every day. It's just a matter of time and hard work.

Firefox will not load. It says firefox cannot load, your profile is missing or inaccessiable. Help!

All of sudden firefox would not work. When I click on the icon, I get a message that says Firefox cannot load, your profile is missing or is inaccessiable. I have tried downloading firefox, everything seems fine, and than the same message appears. No matter what I do I cannot get it to work. I am a long time user of firefox, so this is driving me nuts. I hate having to use Internet Explorer.

Sounds like Firefox is "hanging at exit". That problem is frequently caused by an Extension or a Plugin. Read all of the following articles. 
NOTE: Establish a habit of exiting/closing Firefox with Firefox button > Exit or File > Exit to allow an orderly shutdown of Firefox and closing of all of the files that Firefox has open.

I'm sorry we cannot help you.
You have Jailbroken your device. Apple does not support Jailbreaking and as such having done so has voided your warranty and forfeited any support from Apple and by extension these forums. We are not allowed to discuss Jailbroken devices in any way by the Terms of Service of the forum.
You will have to find help elsewhere. Ask the person that installed Cydia to restore the phone.

Firefox cannot load websites but other programs can

Firefox cannot load any webpages, but IE can.
I have tried everything suggested. This problem happened befoer I updated Firefox and did not resolve after I updated firefox.
I tried changing internet settings, disabling firewall, and even disabling IVP6, but nothing is working.

Have you already seen [[firefox cannot load websites but other programs can]]
*What exactly happens, or does not happen and do you get any error messages ?
*Is it all websites you have a problem with, or only some ?
* What happens if you work offline, can you load web pages that are saved on your own computer ? (save something with IE, -as HTML web page files - maybe this page, then try opening it with both Firefox and IE)
Can you use firefox to look at your local disk such as (depending on your setup) ''file:///C:/''
Try checking security settings, and security logs, is firefox being blocked ?

One day it was fine, and the next day it stopped working! I have tried everything suggested under the topic "Firefox cannot load websites but other programs can."

You should e able to install FlashPlayer separately on IE and Firefox. So you may use Flash 11.3 on IE and 11.2 or 10.3 on Firefox.
Work from the administrator account. First of all sort out Firefox, use the Adobe uninstaller to uninstall Flash before reinstalling 11.2 Afterwards check that IE is ok, the Uninstaller may have changed that so you may need to reinstall Flash on IE.
* see instructions in [[flash 11.3 crashes]]
You are apparently using an outdated Firefox 8. That is not secure you should update to the latest Release Firefox 13 (or within a day or so Firefox 14)
You may also encounter problems relating to use of RealPlayer software and that software may affect use of FlashPlayer 11.3
* see also [[Fix problems with RealPlayer add-ons]]
* a user ''blacksabath710'' recently posted a workaround in [/questions/931055] suggesting use of free software from http://www.dvdvideosoft.com/
P.S.
When you finish set Firefox's FlashPlayer not to upgrade, and until this issue is resolved do not follow suggestions from Adobe, or Plugincheck etc. to upgrade Flash.
Use this test page form Adobe in each browser and account to check Flash is working ok
* http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html
The test page will display version information and error messages or a Flash animation to prove flash is working.

Firefox cannot load certain website

Firefox cannot load this website
http://homewhere.sg/

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.
*https://support.mozilla.org/kb/Safe+Mode
If images are missing then check that you aren't blocking images from some domains.
*Check the permissions for the domain in the current tab in "Tools > Page Info > Permissions"
*Check that images are enabled: Tools > Options > Content: [X] Load images automatically
*Check the exceptions in "Tools > Options > Content: Load Images > Exceptions"
*Check the "Tools > Page Info > Media" tab for blocked images (scroll through all the images with the cursor Down 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.
Make sure that you do not block third-party images, the permissions.default.images pref should be 1.
*http://kb.mozillazine.org/Images_or_animations_do_not_load
There are also extensions (Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images.

Firefox cannot load websites, but other programs can. Listed guide/faq not effective.

I went through the FAQ guide for firefox not loading webpages, but after having changed both boolean setting in the about:config section of the firefox advanced settings, deleting and re-adding it to the program permissions list in my firewall (mcafee antivirus 2011), and even attempting to completely disable the firewall for a period of time, I am still unable to browse the internet on firefox. Internet explorer, however, does work.
