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

Homepage: http://www.mozilla.com/firefox
Description: Firefox Web Browser
with these plugins:
- adblockplus
- flashblock
- foxyproxy standard
- restart browser
- user agent switcher
- youtube all html5
Occasionally, according to no discernable pattern, all my tabs on all
some/most/all Firefox windows stop responding. Clicking and scrolling
in
the content has no effect. Can't open new tabs, can't close tabs, can't
switch to existing tabs. Sometimes it affects only one firefox window,
sometimes all firefox windows.
Imagine if you will that firefox is coded with one global loop that
gets
user actions and responds, then that loop gets stuck somewhere. The
firefox window will not be affected (controlled by KDE), and neither is
the X-server but the tabs can all do nothing till the loop unsticks.
It's an effect like that.
Sometimes it does work after a delay >30s.
The sysadmin in me says 30s? Hah, check DNS resolver timeouts. Checked,
found nothing unusual. Proxy looks OK, VPN looks OK, Chrome never has
this problem so it's firefox specific.
Firefox itself is up, it responds correctly to moving around the menus,
just can't do some of the actions like open the Addons page (that is
regular content in a tab).
The issue ALWAYS goes away if I restart firefox, either with the
restart
addon or Alt-F4 and start from KDE menu. I have "load previous tabs"
set
to true so those actions are pretty equivalent.
DE is Plasma 5, and the problem isn't from a recent upgrade, I've been
battling with this for ages through MANY kde and firefox updates.
My question:
Where the hell do I start to figure out what's really going on?
I used up all my sysadmin troubleshooting knowledge and have had to
revert back to n00b status on this one.
I see this with some websites that do some weird stuff.
CPU for at least one core then also goes to 100รท.
Make a list of websites open in tabs when it happens to see if there are common
ones that are always there when you have the issue.
Good idea. For posterity so's I don;t forget:
- gentoo home page
- one or more readthedocs sites (especially docs.ansible.com)
- 1 or more jira pages (work stuff)
- 1 or more confluence pages (work stuff)
- a local gitlab site
- 1 or more python html apps for, errr, usenets stuffs
- 1 or more python apps running in flask (work stuff)
