Comment # 3 on bug 1192978 from Carlos Robinson

Notice that I have 37 FF windows with a total of 815 tabs.

I started FF now from a terminal, so far nothing gets written there. But as a
side effect, I can now not open any link from Thunderbird: it first asks what
profile to use, and when I select the currently running one, it thinks for a
few seconds and says it is not responding.

If I open a tab and type a link it is working now, maybe it fails later on.

I could also obtain an strace or ltrace or whatever.

Yes, I have some addons.

I have ublock origin - wait, now when I click on "Tools, addons" there is no
response. This is new.

I can not get a list of addons today.

[...]

Ok, found a window that was displaying the addons, on another desktop, that one
was blocking, and focus was not jumping to it.

I have:

 * tab counter - https://addons.mozilla.org/en-US/firefox/user/DaAwesomeP/

 * UBlock origin. When the problem happens, I tried disabling this one, no
effect.

 * Window titler - https://addons.mozilla.org/en-US/firefox/addon/window-titler


Disabled addons:

 * Addblock plus

I will add information later in the day when tabs stop working.


This tab crashed when I clicked on save changes; fortunately, restore all
crashed tabs worked.
