firefox dev tools inspector window keeps going blank

Posted

every few times i switch to FF to debug, the inspector window is totally blank. if i click the inspector tool and highlight html, it will appear to be scrolling over in the inspector window to highlight the code, but the page is totally blank. close/reopen tools fixes, but a few times later its broken again. has been going on for months and months, at least since v32. Using FirefoxDeveloperEdition.

Does this also happen if you use a release version instead of the beta?

Create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

A new profile didn't help.

I don't know for sure, but it may be triggered by alt-tabbing between Dev Edition and Release.
