Often part of the text of a webpage or menu is blurry. For instance when i registered on this site, after clicking on the box to fill in my username the text above it became blurred. Another exemple, when scrolling in the menu with open tab pages serveral lines of text become blurred. This only lasts until i do something for instance scrolling or selecting the text or ctrl+ (using ctrl 0 does not help).
I have a screenshot if i can find a way to upload it here.
Hello jozeph, try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

Try to set the gfx.content.azure.enabled pref to false or if this didn't help disable Direct2D by setting the gfx.direct2d.disabled pref to true on the about:config page and leave hardware acceleration otherwise enabled.
That way you still have the benefit from hardware acceleration, but may not suffer from rendering issues.
You can also try to uninstall Windows update KB2670838 if you have this update.
I've been using the gfx.direct2d.disabled setting for several days now. I haven't seen anymore blurry text so far. So this seems to have done the trick. Thank you for that.
I had read about the gfx.content.azure.enabled somewhere before. I assumed it was a joke. What it does is turn the right click menu into a back box.
Disabling graphics hardware acceleration crashed my firefox and after restarting it i couldn't get the "save my windows and tabs from last time" feature to work anymore. So i had to use the "reset firefox" button.
I was experiencing this too, I've attached an example.
Setting gfx.content.azure.enabled to false as described above fixed it without causing any apparent difference to performance — pages still seem lovely and smooth due to the hardware acceleration.
Interestingly, Firefox isn't the only application where I've encountered this. My code editor (Komodo Edit) suffers from the same issue at times. Anyone know what underlying cause is at play here?
FWIW, my GPU is an ageing AMD 4850. This is probably relevant.
