I do not have mailto configured. My usual practice is to right click on mailto links and copy them. Then paste it to the right place in a web mail interface. This is a stripped down Ubuntu 16.04 built from the mini.iso, amd64 with X and Openbox. Like Lubuntu but lighter.
If I LEFT click a mailto link I get a blank tab that can't be closed. The palemoon window can't be closed. If minimised (iconified) it pops back up instantly. I can't type in the url field or the search field. If I highlight (select) all or part of anything already in either of those fields, the highlighting persists just long enough to see it and then goes away - a fraction of a second. Palemoon becomes uncloseable & unkillable. Not even xkill (and xkill is real bad ass) can do it in. I can get to another tty with cntrl-alt-F2, and log in there. But I can't kill it from there either.
(still from tty2 cause the X session is now unusable) doesn't see it. How can that be? The only thing that works is to kill X and then startx, and then carefully uncheck the offending tab before restoring the PM session.
Code: Select all
ps -wweo pid,args|grep pale
It still happens in safemode. It is not limited to one particular mailto link.
Discovered by accident because I don't normally LEFT click those links, and it is easy enough to avoid, but I thought y'all would want to know, and I am a little curious.
