Have you read and tried the suggestions in the recent thread Is there retina display support for new Firefox 19? /questions/950900. Please look at that and say what you have tried.

This is a relatively new feature and does seem to cause some problems. There are some threads about this but not a mass of feedback about blurry screens.

You did not include troubleshooting information when you posted this. Please paste into the next reply a list of your modified preferences.

How bad is it, maybe post screen shot of it with retina enabled and disabled

• How do I create a screenshot of my problem?

Do you only have a problem when retina is enabled ?

Hi,

Thanks for the reply.

I already had a look at this thread before but it looks like I missed trying changing this setting: gfx.hidpi.enabled. I set the value to 2 and restarted FF and now it's ok, ie graphics look sharp on the retina display.

Definitively a setting that should be defaulted to 2 for mac retina users... if not the user experience is quite bad. I understand this is because there are still some bugs about menus? Any hope for v20 ?

Thanks,

Glad it helped.

As for version 20 that is already out in Beta, but nothing that relates to retina important enough to list here

• http://www.mozilla.org/en-US/firefox/20.0beta/releasenotes/
• or in the putative 21 http://www.mozilla.org/en-US/firefox/21.0a2/auroranotes/ that is out on the Aurora channel

Please do not post in bugs (etiquette), but there is a listing of some related bugs in this one (The info is not user friendly; and the 300+ comment original bug even less so)
