1 This post is rather vague, sorry about that in advance.

3 I've spent much time on this and gotten absolutely nowhere. So I
4 conclude all my thoughts and assumptions are wrong and not worth even
5 sharing (on account of them being so wrong).

31 Homepage: http://www.mozilla.com/firefox
32 Description: Firefox Web Browser

34 with these plugins:
35 - adblockplus
36 - flashblock
37 - foxyproxy standard
38 - restart browser
39 - user agent switcher
40 - youtube all html5
41
42 Occasionally, according to no discernable pattern, all my tabs on all
43 some/most/all Firefox windows stop responding. Clicking and scrolling in
44 the content has no effect. Can't open new tabs, can't close tabs, can't
45 switch to existing tabs. Sometimes it affects only one firefox window,
46 sometimes all firefox windows.
47
48 Imagine if you will that firefox is coded with one global loop that gets
49 user actions and responds, then that loop gets stuck somewhere. The
50 firefox window will not be affected (controlled by KDE), and neither is
51 the X-server but the tabs can all do nothing till the loop unsticks.
52 It's an effect like that.
53
54 Sometimes it does work after a delay >30s.
55 The sysadmin in me says 30s? Hah, check DNS resolver timeouts. Checked,
56 found nothing unusual. Proxy looks OK, VPN looks OK, Chrome never has
57 this problem so it's firefox specific.
58
59 Firefox itself is up, it responds correctly to moving around the menus,
60 just can't do some of the actions like open the Addons page (that is
61 regular content in a tab).
62
63 The issue ALWAYS goes away if I restart firefox, either with the restart
64 addon or Alt-F4 and start from KDE menu. I have "load previous tabs" set
65 to true so those actions are pretty equivalent.
66
67 DE is Plasma 5, and the problem isn't from a recent upgrade, I've been
68 battling with this for ages through MANY kde and firefox updates.
69
70 My question:
71 Where the hell do I start to figure out what's really going on?
72 I used up all my sysadmin troubleshooting knowledge and have had to
73 revert back to n00b status on this one.
