Why is firefox continually blocking valid websites and redirecting?

Firefox frequently (and annoyingly) blocks trusted sites from loading, sites like Sprint.com, for example. I know of no instance where they have blocked a malicious site and I find this practice annoying. How may I stop this from occurring?

It could be the work of one of your add-ons, or even add / mal-ware.
Look thru your add-ons list and make sure you know what each one is
there for. Also, check the programs that are on your computer
'''Windows > Start > Control Panel > Uninstall Programs.'''
'''(Mac: Open the "Applications" folder)'''
Go thru the list and use a web search to check any that you don't
know what they are.

You need Flash Player or DivX Player. Both of these programs are used everywhere online; their size is small and will not harm your computer. You should download them from here:

Why does Firefox always block any link I try to open going to a web page when I don't have pop up blocker on?

Why does Firefox always block any link I try to open going to a web page when I don't have pop up blocker on? First off they are not even pop ups....your crap blocks everything and don't save user names &/or passwords when you have it checked. Also in your tutorials about solving this issue says it has the word "OPTION" .......no, it never says option to allow you to bypass it and etc. Only thing is says is "ALLOW" . That would be nice , but the problem is it will not allow it from then on. It only allows it right then and then you have to refresh...after that to open again it blocks it again.....HOW STUPID?!!!!!
It always say that this is preventing this page from automatically redirecting to another page. THIS IS WHAT I AM TRYING TO DO...GO TO ANOTHER PAGE........I DON'T NEED YOUr BROWSERS PERMISSION TO DO THAT. THAT IS WHAT A *%#$&*(&*%$$%% BROWSER IS FOR TO GO TO OTHER PAGES......THEY ARE NOT POP UPS!!!!!
YOU STUPID BROWSER ACTUALLY BLOCKS EVERYTHING AND THAT SUX!!!
HELP!!

Firefox keeps remembering a website and won't allow me to log out and will not return to login page. been to cookies, saved passord options, nothing helps

firefox keeps remembering a website and won't allow me to log out and will not return to login page. been to cookies, saved password options, says no password is saved but it is. nothing helps

It might be that you are logged in with HTTP authentication (either basic or digest). This authentication is arranged by the browser, so you would have seen a pop-up dialog asking for a user name and password while logging in. It seems that these are cached by the browser and it requires you to restart the browser to log out...
http://en.wikipedia.org/wiki/Basic_access_authentication
http://www.tolaris.com/2009/09/08/logging-out-of-http-auth-with-firefox/
Because I found that having to restart the browser quite annoying I stumbled on this question and also on the HTTP Logout add-on that allows you to log out without restarting your browser. Not many sites use HTTP Authentication, but you might give it a try.

Why is Firefox such a horrible browser and how did it get popular?

'' locking this thread before it gets out of hand - This is a Firefox support form, not a forum for personal opinions about Firefox or Mozilla. If you want Firefox support please ask for it.''
I can't use Firefox, or "Crashfox", more than an hour without crashing. I have a new computer, have tried every fix known to man, so I don't need any "tips".
Due to my endless efforts to fix the many shortcomings of Firefox, I can say without a doubt that its Firefox. I have no clue how this browser gained any popularity or why anyone would continue to use it. I've lost more data than I can imagine because Crashfox just quits. It can't handle any type of load at all. 5 tabs open and its done. I can have 30 open in Chrome and it works like a champ.
I just switched to Chrome and it kicks Crashfox's ass all over the place. Faster, more stable, and just plain better. Hands down, no questions about it. Good luck catching up to Chrome Mozilla.
AND, IF YOU WANT TO BLAME THIS ON THE PLUGINS, THEN DISCONTINUE SUPPORTING THEM. IT STILL FALLS ON MOZILLA.
Why did I post this, because I feel after all of my inconvenience, i should be able to at least make one comment about Crashfox. This post will probably be removed because no one wants to face the fact that Crashfox is inferior. Very inferior.

the truth stings.
the only way to provide support would be to rebuild Firefox.
Chrome spanks Firefox in all bench tests. I even used a FF install w/ no addons. No contest. Chrome hands down.
Firefox is officially bloatware.

Why does Firefox continue to crash?

Can someone please suggest why Firefox continues to crash when attempting to download a file. It happens every time, without fail.
* I have deleted the downloads.sqlite file (more than once) to no effect.
* I have disabled AVG firewall etc - to no effect.
* Firefox originally crashed on the latest version, so I downgraded to v5.0.1 - to no effect. I have checked using AVG and an online virus/spyware checker and can find no infection.
* I have submitted 17 crash reports since 29 September, but when I right click on any of them, and try to open in a new tab, I receive the following messge: “We couldn't find the OOID you're after. If you recently submitted this crash, it may still be in the queue.”
My OS is Vista Business 32 bit. Thank you for any help & advice.

Why does Firefox try to launch Adobe and/or Quicktime when I close Firefox? What is it loading into those programs?

When I shut down Firefox, it tries to start Either Adobe Reader, Quicktime, or both. It has done this ever since the first time I installed an used version 4. The applications do not actually launch, as in a window opening, but they are then present as a process in the system, and I have to close them from the Task Manager. It usually launches just one, but, if it's trying to launch one, and I use Task Manager to close it, it then launches the other. If I hurry and stop that one, Firefox reports that it messed up, and wants me to keep using the Internet for its own purposes that have nothing to do with what I was using the Internet for. This never happened under previous versions of Firefox. Do I need to revert to a previous version? I'm running Kaspersky Internet Security, and it shows I have no malware or the like on my computer, which could cause this. So, why is Firefox trying to do things I did not ask it to, and then expecting me to let it phone home to tell about it when I stop it. By the way, out of good practice, I often close down my Internet connection before closing Firefox, (in case I do get something like a Key Logger loaded, to prevent it from sending its final report before the cache is cleared), but this also happens when I have not yet closed my Internet connection before closing Firefox, so I do not think that is the issue, nor should it be. Your question below about when it happens does not provide for the answer "Every time Firefox Closes", so I picked the closest such answer.

This can be caused by clearing the cookies via [[Clear Recent History]].<br />
* Firefox/Tools > Options > Privacy > Firefox will: "Use custom settings for history" > [X] Clear history when Firefox closes > Settings
You can try to exclude the cookies to test that.<br />
You can let all cookies expire when you close Firefox to remove unwanted cookies and keep the ones with an allow exception.
* Tools > Options > Privacy > Cookies: "Keep until": "I close Firefox"
If you use [[Clear Recent History]] to clear the cookies when you close Firefox then Firefox also tries to clear the cookies from plugins like Flash and starts a plugin-container process for each plugin and possibly for each cookie (?) and that can add extra time if there are a lot of cookies to remove and also can cause an unresponsive script error to appear.

Why does Firefox 28.0 keep crashing and opening up random tabs?

I'm running Firefox 28.0 on a Windows 8.1 laptop. Recently, it began opening up random tabs to spam websites and it's SUPER annoying. Then, the other day it began to do this thing where it'll stop responding. Rather than just freezing up for a second like it used to, it won't unfreeze and I have to restart Firefox. I reset Firefox today, and that didn't solve any of my problems.
System specs;
OS: Windows 8.1
Processor: Intel(R) Core(TM) i3-3227U CPU @ 1.90GHz 1.90 GHz
Installed memory (RAM): 6.00 GB (5.88 GB usable)
System type: 64-bit Operating System, x64-based processor
Pen and Touch: Pen Support
Windows is activated

I've already done this, and it says nothing is wrong with my system.

Why does my Mac block certain websites?

My Mac blocks Yahoo and Facebook most of the time. I was told that this is not my router or modem and is a security issue. Why does it only block specific sites? I can't seem to find anything in my security settings.

You're connected on a private and particularly an access-controlled and restricted network, and the administrators of that network have decided that connected users shall not expend available resources and bandwidth with access to various web sites and/or web services.
If the network administrators have established the blocks correctly, you'll need to use fairly advanced techniques to bypass the blocks, and attempts to bypass these blocks — whether the bypasses are successful or not — may well be considered grounds for network disconnection and/or disciplinary action by the organization.
It's common to log these sorts of failures and attempts to bypass, and — given they have control of the switching gear — it can be feasible to uniquely identify the client computer that's making these requests. If not the specific identity of the client computer system or the credentials used, then the location of the client computer that's attempting the connections.
Check with your network administrators, and with the site's policies and procedures.

Help blocking certain website and IP on a SG 300-20 Small Business Switch

Hi,
I like to block certain IP and website on the SG 300-20.
Being new to Cisco Small Business switch I she tried with no positive result. Could someone give me some steps or maybe direct me where I can find a step by step resource.
Thank you

Hello,
Thank you for contacting us for support with your device.
Unfortunately what you are trying to do is not possible with any Small Business switch.
It is true that this switch can be used in layer 3 and it will be able to route your traffic on the inside of the network, but it will not be able to route your traffic to the Internet as it doesn't do any NATting.
If you need to block any websites you will need to configure it on your router or firewall.
Just to be completely clear, this switch won't be able to block any websites.
I hope this was helpful

Why does Firefox not open my windows and tabs from last time until I have tried starting 3 or 4 times?

I have this problem with opening Firefox:
My Startup options are set to "When Firefox starts: Show my windows and tabs from last time"
However, each time I start Firefox, by clicking the icon in the Taskbar, it opens with a single blank tab.
I repeat this using "Open New Window" and when I have up to 3 windows, all with single blank tabs open, I close them all. Once more I use "Open New Window" which only then opens with my windows and tabs from last time.
Naturally, this induces initial panic each time, because I dread the thought of losing all my current tabs.
What is going on here?
How can I fix it?
< Firefox 27.0.1 with Windows 7 Home Premium.>

This started happening to me with the upgrade to v30. Previously, new windows did the proper thing of showing previous tabs/windows.
I have history on, not in private mode, and have cleared cache.
