Browser Support • Re: Pale Moon 34.3.0 crashing when minimized

Pale Moon forum - Forum index [Unofficial] June 8, 2026

This is interesting, we'll make this a separate thread as your experience may be different from @UCyborg's. Please post the output of Help - Troubleshooting Information in code tags so that we can start trying to diagnose this. Also, you may want to list some of the sites that are open in tabs when Pale Moon crashes for you.

Bellow is the text from Help->Troubleshoot:

The tabs open when the crashes happen aren't interesting in themselves, as they are sites I have been visiting for some time (in the case of MDSN, decades) without problem. They are:

MSDN (https://msdn.duke4.net/hot.php), aka Mikko Sandt's Duke Nukem, a website about Duke Nukem 3D
Hardcore Software (https://hardcoresoftware.learningbyship ... f-contents), powered by Substack
A couple of private web apps, hosted locally and based on a home grown PHP framework/ORM/CMS.

MSDN uses no Javascript at all (its design hasn't changed since the late 90s!), and my web apps use Javascript only for the popup menus. Substack (and thus Hardcore Software) is the only page which uses Javascript. Load is a bit slow, but once loaded, CPU use falls to zero.

Anyway, reading other posters' experiences, this seems to be caused by the sites recently closed. Oddly, Gmail and YouTube have not caused trouble for me, but I don't use them too much in Pale Moon: I have Firefox (gasp!) installed just to access Google apps. Next time it happens, I'll try to make a list of recently closed tabs/windows.
