Incompatibility with Firefox v83

[javiquinte]

We received from ODC a report of a user informing an incompatibility with Firefox v83. Both ODC and GFZ instances fail with the following error:

Loading webinterface v1.2 (2019.331)...
fdsnws.js: initializing
fdsnws.js: access to database denied
fdsnws.js: init failed
Ready.

ODC has checked it various environments with anonymous window, plugins and addons disabled, but no success. The user says Chrome-based browsers work fine.

I tried with a Firefox v83.0 in a Mac and it works perfect. I cannot reproduce.

Loading webinterface v1.2 (2019.331)...
fdsnws.js: initializing
fdsnws.js: init successful
Ready.

I don't have Firefox 83 yet, but generally "access to database denied" means that IndexedDB aka database storage has been disabled, possibly for privacy reasons. Check page rights under right mouse click.

Hmmm, interesting. In firefox 83.0 if you under: "Privacy & Security" -> "History" select the option "Never remember history" this automatically activates "Always use private browsing mode" which causes the issue. The workaround is then to select the option "Use custom settings for history" and then under settings fine tune (do not really find anything there related to IndexedDB though).

There's no "page rights" under right mouse click but presumably "VIew page info" is its successor (under "Permissions" there is an entry "Store Data in Persistent Storage", perhaps this is what @andres-h refers to?).

In any case, thanks for pointing me in the right direction, but perhaps some info on the above may be warranted as the messages in the console on load are rather cryptic (to me at least...)
