I want to disable javascript for websites. I've done this in the previous versions of firefox by unchecking box in options/contens. But there is no disable javascript option in firefox version 29.

An error occurred during a connection to 192.168.1.24:2400. SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message. (Error code: ssl_error_weak_server_ephemeral_dh_key)

Am getting this error .. how do i solve ?

So a lot of pages are loading really slow like minutes, like youtube and hot.ee mail service and a lot more. It started to happen when i updated to 20.0. Looked up some suggestions and found that about:config network.http.keep-alive to false help. And so i did it and it worked, but next time i opened firefox again it was slow loading again, but keep-alive is false still, disabled all not nessecary plugins and extensions and i dont seem to find a solution. Been a firefox user for a long time and dont want to change my browser.

it been 5 days facing this problem while watching videos sometimes it work normally the next day then it crashes I tried other sites some works and some no (the media could not be loaded either because the server or network failed or because the format is not supported )

I am a new developer and I'm trying to learn how cookies work, but I don't know how to view what the actual cookie value is, so that I can check if I did it correctly. I see where you can set the defaults you want and enable or disable cookies, but where can you view the content in FireFox browser? I know in Google Chrome you can see all the cookies and their values in settings, content, cookies, view all. Thanx, Gil

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem."

The page used to load in a new tab before I selected to Refresh Firefox. I cannot find out how to allow Firefox to open webpages in a new tab when selected from the tab in use.

I got corrupted twice last year looking for help. Listed web pgs were scam. Someone with firefox advise me the best ad blocker, MY computer runs several minutes . Ad blockers and pop ups are so enoying

As stated in question, I've recently started getting the message "SSL_ERROR_RX_RECORD_TOO_LONG" when attempting to access various website intermittently. Sometimes reloading the page fixes it. Sometimes it doesn't. Error is only occurring in Firefox, not other browsers.

In Internet Explorer, I have BACK and FORWARD arrows when searching the internet, such as in checking out a site like Walmart.com for a catalog item, but in Mozilla, I can't seem to go back to a previous page without losing the entire program. There MUST be a secret that I am missing..... Help!

I only get sound but no picture or image on YouTube-what to do? I am now using "Chrome" browser whenever I want to visit YouTube, I do not wish to use 2 browsers and I wish to stay with Firefox only. I have tried many solutions without any success. Help!!!!

Hi,

Where does Mozilla Firefox saves the files from add-ons? Don't know if it is from Windows update or from Firefox update, but my add-ons settings keeps on resetting and I lose a lot of data from them because of that. And if I know where Firefox saves those files, then I can make a backup for them.

I have been having issues with certain pages loading correctly but have not been able to resolve the issues. I also tried to create a screen shot to no avail apparently. It's is not with every website only some here and there. Sometimes if I navigate aware and come back to that page it can resolve the issues but more times than not it does not fix the problem. I can also use another web browser such as google chrome or firefox and not run into the same issue. The exact same page will load correctly and as expected. I appreciate your assistance in this matter and I have done some of the trouble shooting steps noted in the frequently asked questions and what you all have suggested to resolve the issue such as clearing the cache, etc but it does not seem to resolve the problem long term

When I click on PDF links Firefox tries to save them instead of opening them. This is so even though in "Options" under "Applications" I have all Adobe files set to "Use Adobe Reader".

When I try to access my gmail account, Firefox says "the page isn't redirecting properly. Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept

   cookies."

I've tried removing cookies, preventing firefox from accepting cookies, and restarting Firefox in safe mode. The best I can get is the log in page, but once I enter my information, I get the same message again. Any suggestions?

How do I prevent firefox from using HTML5 player in youtube and use flash player instead? I am not sure what advantage HTML5 has over Flash. I noticed that Flash plays smoother than HTML5 and there is also a difference in quality of the video at low resolution. HTML5 does not seem to have smooth streaming compared to Flash. I may be wrong and I am ready to learn the advantage of HTML5 over Flash. But until then I wish to revert FF to its previous behavior of playing in flash.

If there is no way of bypassing this player (html5), how do I set it to ask before I allow it to play the video? I dislike videos playing automatically as soon as I open the link or any websites (reason why I set Flash player to 'ask to activate').

Thank you for your generous help. :)

I'm getting this odd error with the standard install of FF since the last few updates every time I try to load FF (even starting up with a blank page) or open a new tab. Tried a fresh profile .. same result. Completely uninstalled FF & deleted the existing profile, then installed again ... ditto. Ran in FF safe mode .. ditto. Disabled hardware acceleration .. ditto. Scanned for nasties (ESET) .. nothing. Installed the latest portable version .. worked fine. Copied the old profile into the portable version .. worked fine. So what could be causing the installed version to give the 'Gah ..' error, both on starting up FF & opening a new tab, but not affect the same FF portable (same version)? The system is an ASUS laptop Win7Pro 32-bit. It's my wife's pc and she uses IE (gasp), so it's not a life or death situation. I'll use FF portable & update now & then unless there's a fix??? One final observation - the first time FF is run after an update or a fresh install, it oddly works then, but shut FF down & restart it .. and all I get is "Gah.." - Gah indeed!
