1963231 - DevTools crashes after indeterminate time

Status: RESOLVED DUPLICATE of bug 1954474

(DevTools :: General, defect)

Description

[Jake]

I had firefox open for close to ~3 weeks on my laptop, I tried to open devtools on a duplicated tab & it would no longer open devtools on any tab after that.

Restarting the browser fixed it. Likely can close the issue as the reproducibility is low, but figured I'd raise in case this occurs again / impacts others & has only occurred for me on this version of firefox.

Error:

Thanks for the report Jake.
This looks like the same issue as Bug 1954474 , which is fixed in Firefox 138 (should be released today)
I'm going to close the bug but feel free to reopen it if you see this issue again
