E-banking site partly dysfunctional with most recent updates

Some pop-up-features of an e-banking site I have been regularly using with TenfourFox before without problem is no longer working, since I have updated to several of the most recent updates (feature parity releases 18, 19, 20). Do I have access to older Tenfourfox versions?

    You can download older versions here

    If an older version indeed works better on your banking site (which would be unusual), please tell us which site it is so we can look into the problem.

    Similar problem.
    Not able to log on to Chase or US Bank sitesover several days. Called website help.
    Best they could do is tell me to empty Caches Cookies.
    Been working for years.
    Using Parity Release 20

    Robert, I removed two spam messages. As to your original post: You posted this in the thread "E-banking site partly dysfunctional with most recent updates".

    Please, as Leinad should do, confirm that your Chase or US Bank logins work in older versions of TenFourFox, but indeed do not work in the most recent updates. We do not have you log-in data to these websites and cannot test this ourselves. Without testing, no bug can be fixed. Thanks for helping to make the browser better.

    Dear Chris, I checked with older versions up to 16.1.. I was wrong - the function bug persists also in older versions. Apparently the banking site changed its functionality. Log-in: no problem. Only the window to perform the online-payments does not pop-up properly. I attached a screen-shot. The top window "Zahlung erfassen" should enlarge upon activating to allow further functions, which is not anymore possible...

    Can you re-upload the screenshot and/or tell me which bank it is?

    Thanks Chris:
    Older versions do not work anymore.
    Downloaded FPR21 and get same error messages as shown above for Chase and US Bank. Other financial sites still work.

    Login links for the two problem sites are:

    Dear Chris

    the site is www.postfinance.ch. As said, no problem with the login. The
    problem starts with certain functionalities.

    Provided FF 52 ESR is used as a useragent string:

    1) https://secure01a.chase.com/web/auth/dashboard#/dashboard/index/index
    None of our usual JS errors appear in the console. Can't tell what's wrong. Works in Leopard Webkit.

    2) https://onlinebanking.usbank.com/Auth/Login?redirect=internet_banking_logon
    Loads fine, I don't see the error displayed in the screen shot.

    3) www.postfinance.ch
    Sadly I cannot test this since I don't have an account.

    I keep getting this kind of error at both 1) and 3):
    Error: WebGL: Refused to create native OpenGL context because of blacklisting.

    WebGL has never been supported in TenFourFox because of limitations in 10.4, so if the sites actually are requiring this for fingerprinting purposes (some sites do this but I'm not aware of any that actually require it), then it won't work in TenFourFox.

    Thank you for your answer, which clarifies the issue, I guess.

    Just strange that all other functions on this site work properly, with
    this exception (although a crucial one)...

    best wishes
