1759693 - Stored breakpoints should automatically expire

Status: NEW

(DevTools :: Debugger, enhancement)

Description

[Jan Honza Odvarko [:Honza] (always need-info? me)]

The Debugger is currently persisting all breakpoints within Firefox storage and there is no way to clean up it. This might be a problem since the amount of breakpoins the can grow over years and have negative impact on performance. It's easy to create breakpoints in a script and never load that script again.

It would be great it every breakpoint is auto-removed after some time (few weeks? a month?)

We might want to thing about the following:

• Storing each breakpoint with a time stamp, so we know its age.
• Updating the timestamp if the breakpoint is active (e.g. hit in debugger, the parent script loaded, etc.)
• One time action: Remove all breakpoints users have persisted (when introducing this new feature)
