Add-On “PrefBar” crashes SeaMonkey 2.52 ⚠️️

One of my favorite add-ons crashes latest SeaMonkey Trunk-Builds like

UNofficial (by FRG) en-US SeaMonkey 2.52a1 (NT 6.1; Win64; x64; rv:55.0) Gecko/20100101 Firefox/55.0 Build 20170513191754 (Default Classic Theme) on German WIN7 64bit

When I launch SeaMonkey it crashes immediately if PrefBar add-on is active.

The problem is not Win64; x64 related.

Bugs:

• Bug 1364078 – CRASH when launch with add-on PrefBar enabled
• mozillazine Bug 26367 – SM 2.52 latest Trunk Builds CRASH when launched with Premier enabled

Can someone confirm the problem❔

Any theory concerning the roots of the problem❔

🆕 unofficial localized SeaMonkey 2.49 ESR for WIN (and other builds) available for download

SeaMonkey Project – calling for volunteers

The SeaMonkey project is entirely driven by volunteers, and we will need some  more of them, as FRG (Frank-Rainer Grahl)  told on mozillazine.

With some HTML and XHTML knowledge (and some endurance, of course)  for example you can do substantial contribution to SeaMonkey Help. Also required: Translation to other languages than English for Help-chapters, Add-Ons, Wiki-pages…

Don’t be shy, leave a comment how we can reach you and where you see your skills for contribution.
