Many site issues can be caused by corrupt cookies or cache.

If there is still a problem, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

How to disable Hardware Acceleration {web link}

Did you try different Windows themes to see if you can find one that works better ?

Hardware acceleration disabled - still same issue. Delete cookies and site data when Firefox is closed is checked. attached is two website examples.

Yes, tried different themes and 'high contrast'. None helped.

The text boxes are plainly visible, if too light for you. Unfortunately, accessibility does not seem to be a design imperative for most of the internet. The images like the duckduckgo logo may disappear when changing settings because they are svg, or simply because changing any colors overrides all or arbitrary color and image settings in a page, which would require a script to set every single color setting. If extensions like Stylish still work in Firefox, you might be able to adjust certain of these color settings on a per-site basis.

For DuckDuckGo, you can change the entire search engine appearance by changing the theme and appearance settings on the DDG main page from the menu in the upper-right, or from any search page, top-center, as well as the upper-right menu. You can save the settings to the cloud (they give you a code to use) or as a bookmarklet.

It's a sledgehammer, but you can inject a custom style rule into every page forcing all borders to black. I just posted a user style for that here:

https://userstyles.org/styles/178024/make-borders-black

The rule is simply:

* { border-color: #000 !important; }

(It would be nice to fine-tune that so it doesn't apply to links but I couldn't find a quick way to do it.)

To install a user style, first install an extension that injects them into pages such as Stylus:

It is how FireFox is handling it.

I suppose I could go into 'about:config' to make alterations BUT that VOIDS support and can break other websites/firefox if not careful. Is anyone WITH Mozilla support going to chime in? Mike

It doesn't "void" support it just makes it harder to diagnose issues without refreshing/reverting Firefox to default settings, which is generally the first-step for all support questions. If people don't mind reassigned these individual preferences each time they potentially run into an issue, then that's okay.

It's mostly a "be careful here, you can break stuff by changing these settings."

In most cases, changes made individually can also be reverted individually, and only certain settings can MAYBE break sites, depending on the site.

Mike, Firefox lets sites set border colors. If the site doesn't set the color, Firefox takes its cue from your OS.

There is not a setting in Firefox to darken website border colors without affecting other colors. So the best solution is one addressed precisely to the problem. You can try the user style and see whether you like it, or not.
