Hi Shaun,

Sorry you are having problems. Possibly it is something odd with your set up.

I am not seeing problems on Ubuntu precise (12.04 LTS) on a 64 bit sytem. I am using Canonical Firefox15.a.2 and also have Mozilla's own release of Firefox 13.0.1 working normally.

Ensure you do you have javascript enabled.
(If so you should see the edit format buttons for Bold, Italic, Links, and paragraph number and bullet listings when posting messages on this forum. )

I would guess some other software extension is interfering try in safe mode, and if that does not help try the new reset feature

• Diagnose Firefox issues using Troubleshoot Mode
• Refresh Firefox - reset add-ons and settings

Start Firefox in Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).

• Don't make any changes on the Safe mode start window.
• https://support.mozilla.org/kb/Safe+Mode

• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

It's not working after restart with disabled add-ons

Sometimes problems with menu display are down to the interaction with the Desktop that is in use. It may be worth trying Ubuntu forums to see if your particular Desktop is causing problems with Firefox.

What is your Ubuntu version and desktop ?

Ubuntu 11.04

Maybe if you boot from an Ubuntu standalone CD or Flash stick, and open a CLI terminal then start your Firefox on the computer from that terminal it would be an interesting exercise. If the problem disappears would that indicate the problem is the Desktop environment rather than Firefox or its profile.

that is bug, how to fix it say

IF you are saying your computer version of Firefox runs ok with that profile, so

• you can for instance see the bookmarks you have made ?
• and have none of the display problems ?

it is looking like a problem with something else not Firefox.

You are probably best trying to get Ubuntu help (if you post on another forum maybe mention this thread, with a link so that they can see what you tried)

IF on the other hand Firefox's Safe Mode or the Firefox reset solve the problem it is a Firefox problem, so keep posting here.

In my firefox 13 checkbox, inputbox and title also not working. Even flash is installed and youtubes also asking install missing plugins. What can i do ? See in this screenshot title of link and video also not working. Thanks for you all replies, but it's all not working :(

Waiting for good reply to solve this issue.....

Thanks, Mani M

Did you try to disable hardware acceleration in Firefox?

• Edit > Preferences > Advanced > General > Browsing: "Use hardware acceleration when available"
• https://hacks.mozilla.org/2010/09/hardware-acceleration/

Make sure that you've installed 32 bit versions of plugins like Flash.

I'm also used with disable acceleration hardware and there is no plugins. When i'm going to install missing plugins, it says the adobe flash is already installed and failed to install plugins :(

Are you using a dark theme in your Linux distribution?

How do tooltips show normally?

Is that with such a dark background?

See this is my about:config
