Symptoms include the options pages and menus of these extensions failing to open, being unable to save any preference changes, or data being discarded after restarting Firefox. If that sounds familiar, be aware it might be caused by having cookies off, using Private Browsing mode or clearing history.

Examples of affected extensions include uBlock Origin 1.14.14, Greasemonkey 4.0a, Referer Control 1.27 and Feedbro 3.30.3.

Bug 1406675 - WebExtension cannot use IndexedDB at all if "Accept cookies from websites" is disabled
Bug 1313401 - Background Page LocalStorage is cleared along with site storage
Bug 781982 - IndexedDB does not function in private browsing mode

The cookie issue can be worked around by creating an exception for the extension, as you would for a website. For instance, if you open uBlock Origin's dashboard, the location bar will show something like this:
Code: Select all
moz-extension://9a86b180-1776-1337-bd69-2ec004f0135f/dashboard.html

That first bit, moz-extension://UUID, minus the folder path and file name is what you use as the exception URL. That string of characters is different for each Firefox profile. If you can't get to the extension's options page, enter about:debugging into the location bar and look for it there.

Firefox 57.0rc1 is out and these bugs are still not fixed.

Instant Translate 4.4.1 affected by bug 1313401.

Sticky thread?

....... when will the Firefox developers finally fix this ?
Apparently this issue was already present before the Firefox Quantum release.
Small, but very annoying issue to me .......

P.S.
Sticky Thread ?
Probably a good idea

Cookies - Will probably be resolved in Firefox 59.
LocalStorage cleared - It depends on the cookie problem being resolved first. The developer working on that took it over a couple of weeks ago, so I guess he'll start working on this afterwards.
Private Browsing - Most recent patch is 1 year old. The person it's assigned to last participated in the bug report 9 months ago. In short, it's not likely to be fixed any time soon.

....... it's not the reply I was hoping for.
That's the new "Firefox Quantum" browser which is going to take over the competition that doesn't have these particular issues ???
Privacy is top priority - Sounds a bit like a Joke in this case.
Anyway, I'll stick with Firefox but it's a shame isn't it ...?...

....... thanks for the news, but the extension in question changed it's name and the developer is asking for cash now.
Even though I liked this add-on (very well done by the way) it doesn't interest me any more.
Still good news that this bug is patched .......
