Firefox-Hilfeforum

Just recently (I believe on Oct 30) I have been encountering this problem while trying to log into the Rooster Teeth web site. I have tried clearing cookies and cache multiple times to no effect, and the help page suggestion for the workaround of clicking "Or you can add an exception..." doesn't work because that button does not appear on the warning page anymore. I am only getting this warning error when trying to log into ( http://roosterteeth.com/home.php ) and only while trying to log in, it doesn't pop up for anything else on the site or any other site that I've gone to. Any help on fixing this problem would be greatly appreciated.

I don't know why I don't have the correct ssl certificate or whatever. I use firefox 60(nightly) I am not sure if I deleted my certificates or what may have happened but it says ssl_error_weak_server_ephemeral_dh_key I don't know exactly what this means or how to get my dh key to give them the right key.

I was trying to load facebook.com and this is error it get

The connection was reset

The connection to the server was reset while the page was loading.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer's network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

any idea how to resolve this?

These are the startup videos and other videos you are supposed to be able to view when you first install Firefox. They're not from Youtube or anywhere else. They're coming from Mozilla's homepage or part of Firefox to help you get up and running when you first install it.

Where can I get a full download of Firefox version 54? I don't want the latest version and I'd prefer to get it from Mozilla itself to avoid relying on another party.

Since the last update of Firefox a lot of my addons don't work anymore. Some of these (security) addons are of greater importance to me than any security issues that a new version of Firefox might fix.

Keep getting the error message below every time I start my computer:

Run DLL There was a problem starting C:\users\John\AppData\Local\Conduit\BackgroundContainer\BackgroundContainer.dll The specified module could not be found.

I have been going on this website for months and today this happened - Access Denied You don't have permission to access "http://www.santanderbank.com/us/" on this server. Reference #18.27a1c017.1419349717.1a5e5aa7

I tried clearing cache and that did not help...???

Hi, This is the last crash report that I have, it happened a few minutes ago. I've tried usig Firefox in the Safe mode already but nothing seems to solve the problem. Can anyone help me please?

Btw, keep in mind that I'm not British or American please ^^

I saw a a previous post with a similar problem (https://support.mozilla.org/en-US/questions/1008744?esab=a&as=aaq) , but it's not for the same sort of content, and the answers did not help me.

I'm trying to view a virtual tour on a website, and I don't know why it's not showing up, but it does if I view it directly.

There is absolutely no indication as to //what// plugin is missing, and where I can get it. I am using the latest versions of Firefox and Flash, on Win 8.1.

You can find it here: http://www.autopano.net/wiki-en/action/view/Panotour_Tutorials_-_Create_a_simple_virtual_tour_and_upload_it_on_Google_Drive#Finished_Tour

It works on every other browser. The full link to the content directly is here, which /DOES/ work in FF: https://49bc6130e8cd1d9c5acf43941b125e6652644cc2.googledrive.com/host/0B21ztMIr_KkXdTNvcHNOYjNlVGc/index.html

I asked for the embed code that was used, which is <embed src="https://49bc6130e8cd1d9c5acf43941b125e6652644cc2.googledrive.com/host/0B21ztMIr_KkXdTNvcHNOYjNlVGc/index.html?html5=only" width="700" height="500"></embed>

Why can't I view the content?

Ps: Your troubleshooter add-on doesn't have a verified author, that's a bit silly.

When attempting to watch any programme on LiveGo.tv there is an error message across the screen where I would normally see the programme "Video format or MIME type is not supported" I have never had this before with Windows XP or Windows 10 but I now have a new PC with Windows 8.1 installed as the OS. I can watch as normal on IE but would prefer to use Firefox.

Any fixes?

I'm getting "Video Format or MIME Type is not supported" flashed on all videos on the CW network site, then the video doesn't play; but no where else. And only with Firefox 32.0.3 in Windows 8.1/64 pro (not N or KN) and in Windows 7/64 Pro on another computer.

I don't have any problems with CW videos using Microsoft IE. Not my preferred browser.

Checked the flash updates and they are up to date.

I did a suggested "disable HTML5 media player" in about:config but that didn't help. Couldn't find any other suggestions for my system.

Hi There,

As of today I seem to be having a strange issue with Firefox 31, I'm unsure as to when this problem began as I haven't developed on this project for around 2 weeks. I have a PHP Development server running on localhost port 8000 using the following command: "bin\php -S localhost:8000 -c php.ini" (without quotes)

Upon trying to connect to this server via Firefox I'm presented with "Firefox can't establish a connection to the server at 127.0.0.1:8000." the message adjusts to show "localhost:8000" when connecting via that method, I've tried running Firefox in Safe Mode, reinstalling Firefox and also changing the network settings to "No Proxy" from "Using system proxy settings".

I'm able to connect through Chrome, IE and also by running a cURL command.

Just recently gotten back into using Firefox. Have been using Chrome. Firefox has one thing that Chrome doesn't have. So I see a number of old Plugs Ins from back when. How do I delete them. I've set to Never Activate. After each Plug In shows RESEARCH. But I don't want to research...I want to delete the old ones. So where do I go from here?

I have also removed trovi from the registry and still every time I open a new tab it goes to Trovi.com

Please help.

Thank you

Like others I am tearing my hair out over repeated Flash crashes (FF25.0, win 8.1).No matter what updates etc - you get the idea....

One solution deep in help is 'Re-initializing the plugins database'. This really works but I wonder is there some way I could run this each time I start up Firefox to pre-empt the problem with Flash?

We had a power outage and when my computer came back on it just opened up a blank session. Restore previous session was not offered as an option - it was greyed out. I (probably stupidly) tried closing and reopening. I've now read a lot of ways to restore them, but many of them I don't really understand. I've found the profile folder, and made a copy of the sessionstore files. Instructions say to right click and press properties and then select "previous versions". This is where I come unstuck. I don't seem to have that as an option. There are tabs "general", "script" "security" and "details" all with multiple sub-options. I can't seem to find anything that says previous versions. I even followed one instruction that said to do this on the folder rather than the file, but there was no option titled "previous versions" on that either. I'm (unfortunately) using windows 8.

I recently reinstalled Firefox on my computer and there is now a plugin called "OpenH264 Video Codec provided by Cisco Systems, Inc.". I have used Firefox for quite some time and have never seen this. Is this supposed to be there. Does it come with the Firefox download now?
