When using Firefox, in rare cases the yellow/black error message "QuotaExceededError: The local storage's quota is too low" appears at the top of the screen.
Solution 1:
Open Firefox settings -> search for "Chronicle" -> set the "Firefox will create a chronicle" field to "create".
Solution 2:
Enter "about:config" in the address bar -> search for "dom.storage.default_quota" -> edit value and enter larger value (e.g. 25120) (default is 5120).
