DOMException: The quota has been exceeded
A site that my company must use daily and frequently for work routinely stops working for everyone who uses Firefox and we get "DOMException: The quota has been exceeded" errors in the console.
Closing and relaunching Firefox usually resolves this temporarily.
I have tried adjusting dom.storage.default_quota but even at hundreds of MB I still sometimes get the error.
The site vendor seems stumped and after weeks back and forth with development are now telling me to use Chrome :( Other Firefox users have been making noise on their product forums but we haven't seen any solutions yet.
I see some bugs in Bugzilla from about a year ago that seem related but it doesn't seem like they are actively being worked. Will there be a long term solution to this?
