1654963 - context menu is empty and hamburger menu does not work

Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

Description

[Harshal Pradhan]

Attachment: FFMissingDropdowns.mov

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:79.0) Gecko/20100101 Firefox/79.0

Steps to reproduce:

My laptop froze due to some unrelated issues and I had to hard-reboot it. Subsequently after restart it, Firefox is now misbehaving.

Actual results:

Items in context menus appear to have missing labels and hamburger menu does not work. In addition I noticed that even some content dropdowns (although not all) are affected. Attaching a screen capture.

Browser console has the following:

Expected results:

Menu items should have appropriate labels.

BTW, restarting Firefox does not make the problem go away.

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

Can you get to about:support? If so, try using the Clear startup cache… (it doesn't remove anything, just clear internal cache). Do you have any Languages installed in about:addons?

I'm afraid this not an actual bug, because something was damaged in your installation when you forced the shutdown (i.e. some files are damaged or missing).

Folks on the support site might have a better chance to guide you through the process to get a functional browser back

Clearing the startup cache fixed it. Thanks for the hint.

I originally filed this as I thought even accidental case of damage in a profile would be worth chasing down and debugging. Ideally, Firefox should detect the issue and try to discard caches ... or something like that. But perhaps that is not worth pursuing since I found a workaround.

I would have no objections if this were just closed as invalid.

Thanks. I'll raise the point about invalidating the cache automatically, but I'm not sure if it would be too costly, and defying the point of having the cache.
