Hi,
after upgrading Firefox to version 47.0 in my Leap 42.1, I started to observe that addon “Friends who listen” did not work anymore (as it did up to version 46).
After some investigation (including debugging the Javascript withing this addon) I discovered that at some point it gives this exception:
dom.storage.default_quota
I already found a workaround from here: https://confluence.atlassian.com/jirakb/accessing-jira-in-the-browser-fails-due-to-ns_error_dom_quota_reached-751633975.html
(different source, same behaviour – but this one was rather old, I see).
By increasing this parameter in about:config, from default 5120 to 10240, now the addon works again. Increase of memory consumption is insignificant for me anyway (Firefox already is at about 1 GB in RAM, from the 4GB total…).
But, nonetheless, I wonder what change in the Firefox “for” Opensuse did this ?
Because version 47.0 in a Windows system did not have this issue.
Also, same addon, the variant for Google Chrome, also did not have this issue (OK, different browser, with different methods).
I couldn’t try Firefox + this addon for Fedora, or other Linux, but I feel this would also work OK.
Am I wrong about it ?
Thanks,
Cornel

The openSUSE package does not contain any modifications in that area.
So if it’s different on Windows it might be an upstream difference
between Linux and Windows.
From https://www.mozilla.org/en-US/firefox/47.0/releasenotes/
FUEL (Firefox User Extension Library) has been removed. Add-ons relying on it will stop working.
Hmm … that’s interesting…
The same downgrade from version 47.0-24.1 to 47.0-6.1 (see here: https://forums.opensuse.org/showthread.php/518348-After-upgrade-to-Firefox-47-from-46-OK-Cancel-buttons-reversed-a-la-GNOME?p=2782416&posted=1#post2782416) solved this issue also !
That is … after this small downgrade, I tried to revert the setting for parameter dom.storage.default_quota to it’s default value.
And now the addon works also, without that error/exception.
P.S. Before that, I also did gave a try to the “upstream” version of Firefox (downloaded directly from Mozilla site, the 64 version). After backing-up and removing folder ~/.mozilla so as to start anew hat downloaded edition, installing the addon again … it worked without any error, also with that parameter at it’s default value.
Anyway, I suspect at least part of the problem with that addon is also due to a very large cache accumulated to my .mozilla folder, especially as that addon is regarded (which has it’s particular cache for it’s internal needs), so now I have a rather empty cache folder, also.
Still, I can’t help but to suspect something is not quite right with version 47.0-24.1 in this regard (parameter dom.storage.default_quota) also.
