User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.186 Safari/537.36

Steps to reproduce:

- Access a site with a unsigned certificate
- Your connection is not secure > Advanced > Add exception
- Click the "Get Certificate" button multiple times

Actual results:

Window "Add Security Exception" size increased.
Size stays the same even after browser restart.
If you click the button too much, you are unable to add exceptions, as the size is bigger than your window.

Expected results:

Window "Add Security Exception" size should not have increased.
Possibly should show certificate information in a new window.
I just found out you have to click View first to trigger this.
I can reproduce this as well.
You can't resize it back, so you are stuck with the new size until you remove your profile.
I just reproduced this on Firefox 58.0.2 (64-bit) on Windows 10. This does indeed happen as soon as the button for viewing the certificate in the window is clicked and then the button for reloading the certificate is clicked.

I have tested this issue on Windows 10 x64 with the latest Firefox release (58.0.2) and the latest Nightly (60.0a1-20180301024724) and managed to reproduce the issue.
After navigating to an unsecured website (eg: ), after going to Advanced > Add exception and clicking the "View" and aftewards clicking the "Get Certificate" button multiple times, the "Add Security Exception" window size is increased on every click.

Moving this issue to "Core: DOM: Core & HTML" for now, which seems the most appropriate component for this.

Firefox 65.0 still has a far to big window here and cannot be resized. So not resolved

Try removing the 'xulstore.json' file in your profile?

Thanks to Dana Keeler, one of my very very old bug is now solved with this file!

And we can change the value of "chrome://pippki/content/exceptionDialog.xul" in the "xulstore.json" file (from chris: for example by:
