Created attachment 8932850 [details] exceptionloosescontext.png User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0 Build ID: 20171112125346 Steps to reproduce: In the debugger for firefox. Happens everytime I try to analyse an exception. Has done that for maybe 7 years, daily, everytime. Regardles of computer, windows type, or firefox number. I work in Windows. Actual results: I get an exception and the debugger halts. And if I am fast enough I MIGHT be able to open the info about the exception in Variables. It is a drop down that often does not have anything in it. It is often so that I can see the debugger updating, after pausing. It flickers. If I try to open the dropdown BEFORE that flickering, the informations is often still there. After the flicker it is NEVER there. I attach a picture showing the drop down opened and empty. So, the update removes the information about the exception. Expected results: Well, the information should still be there.
I don't really know if this is the wrong place to report this bug. I tried to find Firefox debugger, but couldn't. This bug is anyway about Firefox debugger.
