Hi, We have recently updated to version Firefox 131.0.3 and I am having issues with the debugging tools not loading the source code from IFrames correctly when they are selected as the target frame. We use Dynamics CRM which uses a lot of IFrames but when you select the target frame in the debugger the html is not displayed, only the JavaScript is loaded but it looks a bit dodgy and doesn't have full functionality such as variable values being displayed when stepping over them if I refresh the page the source loads correctly but this a pain having to refresh the page after every time opening the debugger. In version 79 (old I know lol) this was not a problem, selecting the frame refreshed the sources and you could debug them straight away. Anyone else having this problem? and is there a workaround? Hope someone can help. Cheers John
