Steps to reproduce:
Used firefox devtools, used breakpoints, debugged stuff.
Actual results:
I'm not sure if it was directly after setting it (I'm not even sure if I've set the breakpoint where it's listed) but I've noticed a breakpoint I can't remove.
I'm removing it, it disappears, I toggle devtools and after what seems like the time it takes to load source maps, it appears again.
Expected results:
The breakpoint should stay removed.

Piotr, thank you for the detailed description. We had some more bugfixes landing around breakpoints in 69 – are you able to reproduce the issue in Nightly? You can use both profiles side by side, so it would maybe help just to use Nightly for some debugging sessions and see if it happens again.

closing as it is likely fixed in nightly, but feel free to re-open if you can still reproduce it.

I didn't notice it lately so it's most likely fixed :) I'll let you know if I notice it again.

It also happening to me. Similar to OP, the breakpoint is also in Typescript.

Darn, I'm not able to get a simple repro. I'm only seeing it in the company I'm at's (complex) app.
I'm attaching my attempt in case anyone wants to try to repro with that. It can be run with
cd repro_attempt_devtools_breakpoint
python3 -m http.server

Thanks for the test case. I put that online here: http://janodvarko.cz/tests/bugzilla/1554054/example.html
I can't reproduce the issue using that page. Are there any specific steps?
E.g. specific line I should create a BP at?

Sorry, I may have caused confusion there, I also wasn't able to repro.
Although I tend to see 2 other possibly related bugs in addition the bug described in this bug report. I think all 3 bugs could be related because they all occur when I have a pre-existing BP and reload a page. I see I am now able to repro the second bug which is described in the following steps and shown in the video attached.
- Open new window
- Load http://janodvarko.cz/tests/bugzilla/1554054/example.html
- F12 to open DevTools
- Insert a BP, say line 3
- Refresh and observe that it correctly stops on line 3
- Hit continue
- Observe that in the top middle, a widget now incorrectly appears saying "Paused on breakpoint". The "continue" triangle icon is not clickable. You then have to click the "Pause" icon in the DevTools window.

Thanks for the update!
This scenario is covered by bug 1580394 I copied the test case over there too.
