Since upgrading to Firefox 23.0.1, I noticed I was having intermittent issues with no audio in Youtube videos. I have since discovered that, if I go to youtube to watch a video, there is no audio. The weird thing about this, though, if the video is linked through a forum, and I watch it embedded through that forum, it works fine.

Other video sites (test site linked in the FAQ and the videos on mozilla.org) work fine. If I open the youtube video in IE, it works fine.

I've tried searching these forums and the internet in general, but I'm not seeing anything similar.

I've had Firefox 4 since the release date, but today it's been acting up - it's not loading certain webpages properly, removing all the formatting and just putting all the text/links/etc in a list along the left hand side of the window. It's also not showing some pictures at all any more, although they're all hosted on Photobucket. This is literally ther first time there's been a problem with it since updating, and I've not changed any settings on it at all, so I have no clue why it's suddenly broken. Is anyone else getting this?

After upgrade, try to use firefox and chrome, it would not go anywhere, IE Edge works fine. Tried reinstall the two programs, doesn't work

This is suppose to be a site that my husband was given by his employer ,To go to and pick out a 10 yr service award. I can't seem to access it, It tells me my server can't access this site. I have type it in several times,but can not get it to come up. The page that comes up asking do you mean------------ I click on what I typed. And I notice other suggested sites on that page apparently have something to do with the (rb), that's all I can tell you.

I was trying to download: https://addons.mozilla.org/en-US/firefox/addon/smallringfx-darkmagenta-213952/

The tab came up top, and said the following: This add-on could not be downloaded because of connection failure

I double clicked something at the top of my browser and then my address and Google search bars disappeared and I have no idea how to get them back and this is my school computer and I really need these bars back!

I do web development. I was working on a site with a self-signed certificate and therefore had to create an exception in Firefox to access the site using https. Due to unrelated problems on the server, I deleted the account and then recreated it. I also had to create a new self-signed certificate. Now Firefox returns the message Error code: sec_error_reused_issuer_and_serial. I deleted the original exception from Firefox but it still returns the error. I tried to explicitly create a new exception but that returned the error, too. Note I do not have this problem with other computers on the same network and the problem does occur if I move the offending computer to another network. i.e., the problem is associated with the computer, not the network or router.

Since I've upgraded to Firefox 19.x, font rendering has been completely broken. Fonts are all messed up, distorted, etc...

See here: https://support.cdn.mozilla.net/media/uploads/images/2013-03-07-20-12-39-1f0313.png

I've read through many suggestions about changing options in about:config, and various other settings, but nothing seems to work.

The browser is totally useless like this.

Any help on how to fix the font issue would be greatly appreciated!

This has just started happening: every time I try to print from a remote website (thetimes.co.uk) I get this message:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

It is not the website, as the request works from Microsoft Edge.

I can't see any changes to the parameters which might have affected this.

Any ideas please?

Someone else used my computer to log in to their gmail account a long time ago. Now, everytime I want to log in to my gmail account, their profile pops up. I can't log in to delete it, and it is annoying because I'm always asked to log in to their email first...rather than my own. I could easily delete the user when I log on using google chrome...

I'm trying to log into a hotmail.co.uk account via mail.live.com and keep getting the above error. I have cleared recent history and disabled Adblock but no success. I'm using Windows 7 SP1 and Firefox 5.0:

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.

The error page then received is as follows:

Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<configuration>

   <system.web>
       <customErrors mode="Off"/>
   </system.web>

</configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<configuration>

   <system.web>
       <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
   </system.web>

</configuration>

Would appreciate any help you can give. Many thanks, Ben

After Upgrading to FireFox 21 my browser no longer can detect that I have the Citrix ICA Client installed and prompts me every time I attempt to launch an .ica file from the internet. Upon multiple installs of the ICA Client from the prompts including Uninstalling it completely then reinstalling it I ignored the prompt and tried to launch the .ica file. It will launch only 1 .ica window no matter how many .ica files I click on. (Firefox 20 would allow me to launch several citrix sessions at a time.) Also when the 1 citrix session is open if I minimize it or bring another program to the foreground the .ica window becomes black and is no longer usable since you can no longer see anything in that window. Is this a known issue?? Currently I have had to unistall version 21 and found a version 20.0.1 that Ive installed disabling the automatic updates.

Hi Friends,

I recently was given permission to edit a website (made with django). When I finished editing, and saved the new edits, I got the following error from Ff:

"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 have all cookies allowed for this site. And I don't know what else to do. I've contacted the admin for the site, and he says there is no redirect that he knows of. And I've looked at the page source and don't see any redirect in the code.

Note that the edits I made were successfully saved. Also, I have no idea where it might have been redirecting me to or through, since it was my first time doing this. But again, the admin says there are no redirects.

Can you all give me some info about this error message, that will help me to track down the problem?

Thank you very much.

PS -- And please don't reply by posting search results on the topic title. I've already done that and didn't find an answer. Please reply only if you know something about this. Thanks  :-)

I have a Tomcat server which I would like to visit via it's IPv6 address.

In IPv4, I would simply type http://<ipv4-address>:8080 in the URL bar.

In IPv6, I can't seem to find out what I have to type in the URL bar - every request I make sends me to my default search engine.

Among others, I tried the following:

http://[<ipv6-address>]:8080

http://[<ipv6-address>%eth0]:8080

To my understanding of RFC 5952, this should do the job.

However, also skipping the destination port doesn't seem to send me to the server on port 80 or 443:

http://<ipv6-address>

https://<ipv6-address>

I've even tried to add the host in my /etc/hosts, with any of those lines:

<ipv6-address>%eth0 foo

<ipv6-address> bar

Still, requests such as

http://[foo]:8080

http://foo:8080

http://[bar]:8080

http://bar:8080

also don't seem to work.

Firefox version in use is 44.0.2

Thanks for your help!

On Internet Explorer I can open an ftp site with "File Explorer", and I can upload files onto the site. However, on Firefox I can't find this option. I need to upload files onto an ftp site for my work, and Firefox doesn't allow me to do it.

Firefox automatically sends me to Outlook when I try to get to Hotmail.com. I have a Hotmail email address and cannot access it. Works OK with Internet Explorer and Google Chrome.

Up until a week or so ago, I was able to run locally saved flash files through firefox on my computer.

Open folder on desktop, run.. 'stupid game.swf'. Play for a while, shut down, go on with day.

Worked for months.

Just a couple days ago, after not messing around with 'stupid game'.. I tried to open it.. and firefox comes up 'white screen'.. not working, where it was working just a week or so ago.

Try I.E... it loads there. Youtube works.. websites with embedded flash (kongregate, etc).. work fine.

Just, firefox itself doesn't seem to like local flash.

Have fixed issues like this in the past of deleting the file 'mimetypes' from my profile.. but, I dont seem to have one.

I've right clicked the .swf in my computer.. and it shows IE as acceptable.. but doesn't show firefox. Heck when I say 'add program' and browse to firefox and try to add it that way, it doesn't show up.

No I haven't installed anything (except maybe a game through steam) and no patches/updates.

Windows 7 here.

For the past month, maybe longer, Firefox has been extremely slow. The videos are also delayed. I have used firefox for many years and now I am disappointed with this browser. I cleared the cache and cookies, twice within a week. No improvement. I've been using Safari for my videos, but all my bookmarks are on firefox. How can we fix this problem? Whats going on ??

In typing the question, I find that the two keys are reversed. (shift+2 displays ", shift+' displays @) This happens on any page displayed via Firefox. The symbols displayed on typing each are correct on pages displayed with internet explorer, and also in local products such as word or excel. Win 7, Firefox 33.0.2
