Problem solved


I would like report that I've had this issue on Lubuntu 14.04 and Firefox 29.0 I followed the instructions above and the black line is now gone.

Thank you very much because it was driving me crazy!

Thanks Habitual. Your "promise to be careful" made me nervous. lol So I type "about:config" in the terminal? Then I am careful. Then in the search bar of Mozilla I type the gfx...thing. Then I right click (or hit F12) and Toggle to make it false. (What's "it"?)Then I exit Firefox and open it again and the black line is gone?

Oh great, this is working for everybody but me!

Nope, not in the terminal. That's your problem. You type about:config in the navigation bar of your browser. Then brace yourself for a rather hefty list.

"it" specifically is the configuration element called "gfx.xrender.enabled"
Open a new tab in your browser and type "about:config" without the quotes.
Search for gfx.xrender.enabled
Right mouse click this value in your config editor and select Toggle.
This will turn the element's property value to false
Close the configuration editor tab.
Restart browser and you should be good to go.

Here's what your may look like before changing this property's element value to false.

Great stuff, Habitual! It worked perfectly. Before, I thought you were just telling me to be careful (in a general way) and so I got a little freaked. Now I can see what you were saying. Now I can start using Firefox (I'd been using Chrome because of the black line) again. Lots of people tried to solve this. You must be pretty good to be the one who did. Thanks tons!

Lightbulb Better way

Hey,

for my old intel gfx card I found a better way to work around this bug: switch from SNA to UXA acceleration. How to do this exactly differs in distributions, but usually you create an /etc/X11/xorg.conf with the content given here:

https://wiki.archlinux.org/index.php...ics#SNA_issues

This way you may fix graphics bugs elsewhere (for me, video playback works better with uxa, too) and still have hardware acceleration in firefox (much smoother scrolling, for example).

Just to thank Habitual, and let others know that this ^^^ worked for me.

It only happened after a routine update, so not sure what went wrong, but fine again now

When Firefox 40 came out this quit working for me and all my other clients. All I got was a blank firefox window. I had to go in and create a new profile and go back in and set enable. Then I went into themes and added FXChrome theme. Now it works again.
