Why do I see "Your browser is not supported" on many sites with firefox 15?

Some sites, like trello.com and many others tell that I seem to use old browser, or that my browser is not supported, and ask me to download Firefox 4 or older.
Is it just irresponsible web-developers, who put this sign for any browser except those in a list, and who then forget to update the list? Or is it some issue with FF itself?
Is there any simple workaround without using UserAgent changing plugins?

Many thanks, it helped, my useragent appeared to be overwritten by apple updater.

Hi Uma,
good that your issue is resolved. we are generally modifying/adding the header to override the existing version to previous version, so instead of using the FF10+ header we are just modifying it to FF9 inorder to make it work
The UA string of Firefox itself is broken down into four components:
Mozilla/5.0 (platform; rv:geckoversion) Gecko/geckotrail Firefox/firefoxversion
Mozilla/5.0 is the general token that says the browser is Mozilla compatible, and is common to almost every browser today.
platform describes the native platform the browser is running on (e.g. Windows, Mac, or Linux). Note that platform can consist of multiple "; "-separated tokens. See below for further details and examples.
rv:geckoversion indicates the release version of Gecko (such as "10.0"). From Firefox 5.0 and Gecko 5.0 onwards, geckoversion is the same as firefoxversion (described below).
Gecko/geckotrail indicates that the browser is based on Gecko. geckotrail is "20100101" in desktop release builds and does not represent the actual build date of the browser. For desktop development builds, geckotrail presently indicates the build date of the browser, but this is likely to change in the future. Starting February 1st 2012, geckotrail is the same as geckoversion and firefoxversion in Firefox for Android with a native front end (aka. Fennec Native).
Firefox/firefoxversion indicates the browser is Firefox, and provides the version (such as "11.0").
Thanks,
RM

Hi, I know how I can correct an inconsistency in the Firefox 4.0 beta 8, the error is: "sorry your browser is not support program by web dympro. " In IE there is a compatibility option firexfox view settings but can correct this error.

Pandora message "Pandora believes your browser does not support modern SSL/TLS" and everything seems disabled on the site-how fix?

I have been using Firefox for a long time as my browser and typically play Pandora while at my office most days. For the first time today I received a pop up message "Pandora believes your browser does not support modern SSL/TLS. Consider upgrading your browswer" when I logged on to Pandora. I checked and I am on the latest version of Mozilla Firefox. I am unable to control volume or log out of Pandora now. I did some google searches and found Mozilla disabled ssl3.0 due to a "Poodle" attack. Does that mean that I can no longer use Firefox as my browser when I want to listen to music on Pandora or is there "a fix"? Thanks!

Mozilla Firefox as of Firefox 34 has the vulnerable SSL 3.0 disabled and only allows for TLS 1.0 at minimum to 1.2 now.
https://blog.mozilla.org/security/2014/10/14/the-poodle-attack-and-the-end-of-ssl-3-0/
So Pandora is incorrect if they believe Firefox is not safe to use.
Actually Pandora potentially needs to do a bit of upgrading themselves.

Your Client Does not Support Opening this list with Windows Explorer on Windows Server 2012 R2

I am trying to open a document library in Internet Explorer 11 on a Windows 2012 R2 server and I am receiving Your Client Does not Support Opening this list with Windows Explorer

Hi,
According to your post, my understanding is that you wanted to open a document library with the Internet Explorer 11 on a Windows 2012 R2 server. But you received the following error message: Your client
does not support opening this list with Windows Explorer.
There can be multiple reasons for it.
So, I recommend you can check with the following steps:
Go to the “Server Manager” of “Administrative Tools” > Enable the “Desktop Experience” feature in your environment.
Go to the “Services” of “Administrative Tools” >
Ensure the “WebClient” service is started.
Ensure that your computer has supported Web browser.
Ensure that Internet Explorer is configured correctly to add
https://*.sharepoint.com to Local intranet site in the “Security Tab” of “Internet Options”.
Ensure that
you have applied the latest updates on the system.
For more information, you can refer to the following articles:

Your client does not support opening this list with windows explorer - related to multiple uploads?

Hi folks -
I've read through some threads regarding "Your client does not support opening this list with windows explorer" and it seems a lot of folks have a lot of solutions throughout the forum posts. Is there anything official or semi-official regarding
this?
I've tried a lot of the fixes including:
checking to see if the WebClient service is on
modifying so-and-so registry (I've since changed them back since they seem to have no effect)
and changing various settings in Internet Options including making sure the site is in the Local intranet zone.
I could live without this functionality but just recently my upload-multiple-files functionality in SharePoint 2010 has also gone away (red x instead of directory UI). I wonder if it's related somehow and could give us a clue.
If it helps I'm using various browsers but of the IE flavor 8 and 9 32-bit as the base for testing this.

For SharePoint 2013 (so could apply to 2010 as well), my problem was that I was trying to "Open with Explorer"
something that probably can't be opened with Explorer. In my case, I just wanted to open my team's Shared Documents with Explorer. I found that when I first log into SharePoint and view the page, I'm presented with those Shared Documents, but also other things
as well.
To get "Open with Explorer" to work, I must click "Shared Documents" under the Libraries heading on
the left. Then, all the other stuff (Links, Getting Started, etc.) go away and I'm focused on my team's shared documents. From there, I can go up to the Library Tools section in the ribbon, choose the Library tab in the ribbon, and click Open with Explorer.
Works like a champ on Windows 7 64-bit, running IE 9 32-bit.
Unfortunately that's not what was going on in my case. One obvious way to check is to see if other people or other computers can Open with Explorer. In my case it was just this one machine on my desk that had the issue.

Trying to open a sharepoint library in Windows Explorer via IE 8 results in the error "your client does not support opening this list with windows explorer"

I am attempting to connect to a Microsoft Sharepoint library, via the "Actions -> Open in Windows Explorer" option from the Sharepoint page. When I do so, I get the error message "your client does not support opening this list with windows explorer". In short, I am trying to get the "drag and drop" functionality of a Sharepoint library.
I am running Windows 7 64-bit and IE8. The target Sharepoint environment is a MOSS 2007 EE. My Windows "WebClient" service is running, and I have no problem connecting to this exact library via a Windows XP computer running IE8.

Verify that the Webclient is started automatically from the Services.msc
Verify that your Portal is in the Intranet local security zone (You can reach it from Your Internet Explorer Browser Security Tag) if not add it to the list
restart the WebClient service if it's work good
If not you have to create a network share to your portal URL directly not your documents library.
Open Windows Explorer or My Computer from the Windows Start Menu.
From the Tools menu, click Map Network Drive…. A new Map Network Drive window opens.
In the Map Network Drive window, choose an available drive letter from the dropdown list located next to the "Drive:" option. Any drives already mapped will have a shared folder name displayed inside the dropdown list, next to the drive letter.
Type the name of the folder to map wich is in this case your SharePoint Portal URL (Don't include the documents libraries)
Click the "Reconnect at login" checkbox if this network drive should be mapped permanently. Otherwise, this drive will un-map when the user logs out of this computer.
If the remote computer that contains the shared folder requires a different username and password to log in, click the "different user name" hyperlink to enter this information.
Click Finish.
I am looking for a suite method :)

Explorer View - Your client does not support opening this list with Windows Explorer MOSS 2007 '

We recently had a major deployement, after which Explorer View started giving error message.
Before deployement, all was working fine.
Error: Your client does not support opening this list with Windows Explorer
Webclient service is already enabled.
The site has been added to trusted site lists.
All Active-x controls have been enabled.
Browser: Internet Explorer 8 - 32 bit.
Microsoft Office 32 bit is also installed.
Thanx in advance.

You could try updating the following registry key on a client PC as a test: HKLM\System\CurrentControlSet\Services\WebClient\Paramenters\AuthForwardServerList to include the URL of your sharpoint site. Add the root site and it might enable this functionality.

Hi,
According to your post, my understanding is that you got “Your client does not support opening this list with Windows Explorer” error.
Did you enable the both authentication (Windows and FBA) on default zone.
As far as I remember when FBA is enabled on the same zone when Windows is used, it breaks whole client integration.
So it will be better if you will recheck your architecture and will use different zones for Windows and FBA.
There is also another thing to try: use claims based authentication with authentication provider which will work both with Windows and FBA.
What’s more, you can also check with below steps.
Use compatibility mode to check whether it works.
Open IE->Tools->Compatibility View Settings
Add the site into Trusted sites to check whether it works..
Open the IE->Internet Options->Security->Sites->add the site into the Websites, then check whether it works.
In addition, you can also try to enable Basic authentication on the client computer, by setting the BasicAuthLevel registry entry of the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters

IE 9 in EP 7.00 SP24 - Your browser is not supported by Web Dynpro

Hi Experts,
We have implemented in our Portal the SP24, and according to PAM ( http://service.sap.com/pam ), the latest version of Internet Explorer, IE9 should be available. Here is a quote about the system information in the administration page of our Portal where is it possible to see that the SP is fully implemented:
Software Components
Name                                 Version                                                                                Applied
sap.com/SAP-JEECOR       7.00 SP24 (1000.7.00.24.0.20110405094932)                           20110805185504
sap.com/SAP-JEE              7.00 SP24 (1000.7.00.24.0.20110405094838)                           20110805212442
Although the SP24 is implemented, we still receive the following message when we acces to a Web Dynpro for Java App:
Sorry, your browser/program is not supported by Web Dynpro!
Does anybody knows whats wrong?
Thanks!
Regards.

Hi Nicolas,
What version of IE9 are you using?
According to SAP Note 1599159 https://service.sap.com/sap/support/notes/1599159 the following restrictions apply:
1. At the moment the 64bit version of IE9 is not supported.
2. The new "Quirks Mode Emulation" is not supported at this time. Further details are available in note 1590563.
Also, in the same note, it states:
When attempting to display a web dynpro application in IE9, the following message may be outputted:
"Sorry, your browser/program is not supported by Web Dynpro!"
Additional details regarding this issue can be found in note 1347768.
...however, note 1347768 seems to apply to IE8 only, but might be of help for your case as well
Hope this helps!
Robin
