Unable to run project on browser

[Serena Roin]

Being that GWT is unsupported on the recent browsers, and my PC has natively Windows 11, I've tried to launch my project on Edge with Internet Explorer compatibility, but it gets some problems. 

On my older PC I had downloaded Firefox 24.0.3, but now on this PC I get "ssl_error_no_cypher_overlap" error. I've tried the main solutions on the net, like the one proposed in https://kinsta.com/blog/ssl_error_no_cypher_overlap/#:~:text=The%20SSL_ERROR_NO_CYPHER_OVERLAP%20error%20occurs%20when,Sockets%20Layer%20(SSL)%20protection.

Anything seems to work to launch this project on any browser, do you have any solution?

Hi! 

What makes you think this has anything to do with GWT? Your application is not dependent on the browser. 

Cheers

Hi Ralph, thanks for answering! I know it is not dependent on GWT, but the application uses gwt 2.2.0 and cannot be updated, therefore I need a browser which support my app. The error of firefox doesn't depend on GWT, because it gets the same error on most of the sites except google. I was only wondering if someone knows a way to use a different browser or if there is a way to make firefox 24.3.0 work!

Every application can be updated if you put enough time/money, so not updating is a choice. Conversely, the cost of not updating increases as time passes (what you're experiencing here with development environments that are hard to setup).

If you (or your management) decide to live "in the past", then go all out: use a virtual machine with an OS and all libraries and applications from 13 years ago (GWT 2.2.0 was released in February 2011), and try to preserve snapshots of it to make it easier to setup in case it breaks somehow.

That being said, unless you're trying to debug an application deployed with HTTPS (in which case you'd have to downgrade its security to support such an old Firefox version: https://wiki.mozilla.org/Security/Server_Side_TLS), there shouldn't be any HTTPS in play, unless maybe to download the devmode plugin. You should be able to download it separately (using another, more recent browser) and then install it in Firefox.

Hi Thomas, 

Thank you, unluckily updating is not a choice of mine, I was thinking to use a VM too, but I was also hoping to be able to do something without reinstalling all the project and libraries another time. 
Anyway if it is the only solution I'll try.
