I'm really upset about a recent change in JIRA.
In a recent JIRA update the browser functionality "go to the previous page" is not working for JIRA which is really a nightmare to follow the links back and forth between JIRA tickets.
It represents a great setback in the usability of JIRA, which makes JIRA ticket management much more complicated and therefore reduces a lot our productivity.
I'm really disappointed with that change.
