firefox dropdown menus break after url launched from dash

Status changed to 'Confirmed' because the bug affects multiple users.

Firefox 14.01, Ubuntu 12.04, Kernel 3.2.0.27, Unity 3d

I'm having the exact same problem.
Firefox menus reliably stop working whenever I open a web page from the HUD/dash.

I've tried in safemode with the same result.

Regardless of what I'm doing in Firefox, when I open a link from the HUD I get to click on menu one time, after that all dropdowns are gone (including searces in the url bar).

I've only used 12.04 + unity a little over a week but I believe it didn't happen the first days so it may be related version 14, at least I only noticed it in the last couple of days.

Upon furter research:

This happens only with the "ask ubuntu" lens but not with the video lens which opens links to youtube. So it must be related to the way some lenses send links to firefox.

Yes it happens in Firefox 14.01 , Ubuntu 12.04 64-bit , Kernel 3.2.0.27.29 , Unity 3d.

Apart from Drop-Down Menu , it also disables my RIGHT-CLICK menu in Firefox , nothing happens on right-clicking .

On continues Right-clicks it shows a tranparent Right-click Menu's Rectangular Border and nothing else.

Upon restarting Firfox this problem vanishes , but using Ask-ubuntu lens again triggers this behaviour. Restarting Firefox seems to be current workaround.

i think this should be reported in https://bugs.launchpad.net/askubuntu-lens page rather in Firefox, since Ask Ubuntu lens seems to be the problem . Please comment so , so i would report theis bug in Ask Ubuntu lens page.

It also happens with the bookmarks-lens and with a quickly-based lens I have written: https://github.com/gbishop/favorites-lens

Since Firefox breaks, there is some bug in Firefox on in the unity interface to it. A lens should not be able to break the browser with a URL.

I can't find the source of the youtube lens that does not cause this problem but I guess it handles the URI itself since it allows choosing the player to be used. If a lens handles the URI and (for example) using xdg-open to activate it, the bug is not present.

The bug only occurs if the lens relies on the dash to open the URL.

Following can be a different bug, but I hope that this is likely to be the same bug:
1. Open Thunderbird
2. Open account settings *from HUD* (it is needed to open it from HUD and NOT from Thunderbird overview page)
3. Try to expand some dropdown menu (e.g. "Outgoing Server (SMTP)" or "Server Settings / Connection Security").

The same proglem appears. The dropdown men does not expand. Since both Firefox and Thunderbird are Gecko-based and there are similar Ubuntu add-ons, I hope this is related.

This is probably duplicate of bug 1035755.

I remember having this problem from time to time, but I can no longer reproduce it on Ubuntu 12.04 and Firefox 16.0.2.
Anyone can confirm?

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

Ubuntu 12.04 (precise) reached end-of-life on April 28, 2017.

Do you still see a problem related to the one that you reported in a currently supported version of Ubuntu? Please let us know if you do and in which version of Ubuntu otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
