Hi

If you wish, you can download a theme more to your liking from https://addons.mozilla.org.

Thank you Seburo. I have tried half a dozen since this updated on me this AM. I have not found one that is as clear to reas as the old one. The tabs for instance, on several are so faintly changed in outline color it is not possible to tell very easily which one is active. I fail to see why the theme change could not have preserved the previous them, even if the layouts and some of the features were otherwise changed. Thanks for you help. I have to say that Firefox has been my browser of choice for years, but I am not evaluating others. Buzz

Hey, A theme called Photon Colors solved this issue for me you can try it out, I will be attaching a link to the same below. https://addons.mozilla.org/en-US/firefox/addon/photon-colors/

Thank you Mamoon. I have installed the Photon Colors theme, and it is tremendously better. Strikingly clear and simple. I had tried a number of alternative themes yesterday, and none were anywhere near as easy to read as Photon Colors, especially if one prefers simple themes without a lot of artwork that makes seeing text difficult. Thanks again Mamoon.
