How to actually fix HiDPI?

It's now Firefox 23 and the HiDPI mess is still going strong!

Does anyone know how to actually fix it and return Firefox to looking the way it did up to version 21 or is going back to 21 the only viable solution?

I did try the whole messing around with layout.css.devPixelsPerPx but it doesn't work - interface text gets too small and blurred, icons on the other hand are still big and blurred, and website content is HUGE. In addition to this Firefox feels slower.

Hi AuldWolf, you usually cannot get an official response about future UI plans here in the support forum. It might happen, but you may need to raise the question in other ways.

If you decide to install Firefox 26 "as is," I think the main problem is losing the site-specific zoom levels. I mean, you can easily force the scaling to 100% by changing the devPixelsPerPx setting, but I'm not sure how to migrate the site-specific zoom data from the pre-Firefox 22 format to the newer format (assuming that is what needs to be done).

Your userChrome.css file might need manual editing as well, but the extent of changes probably depends on whether you are using absolute measurements (e.g., pixels) or relative measurements (e.g., em or percent).

What about:config settings do you think would get lost?

Set the layout.css.devPixelsPerPx pref on the about:config page to 1.0 and if necessary, adjust layout.css.devPixelsPerPx starting with 1.0 in 0.1 or 0.05 steps (1.0 or 0.9) to make icons show correctly.

You can look at the Default FullZoom Level or NoScript extension if web pages need to be adjusted after changing layout.css.devPixelsPerPx.
