Screenshot is not useful because you're not showing the entire browser? Provide link(s) and steps to replicate so that we can try. Windows home or pro? What security software besides MS Defender are you running? If you're running Windows Pro version, I would test in the Sandbox to confirm. https://www.howtogeek.com/399290/how-to-use-windows-10s-new-sandbox-to-safely-test-apps/

I have no issue on the home page. see screenshot

Another example taken from this website. Note that others have had the same issue. No solution is ever given. Just more questions. Chrome and Edge do not have this issue.

You didn't answer Jonzn's question - what OS you using? This would appear to possibly be a locale/localization issue - via the OS. In firefox General settings have you checked the Fonts? Then check Language and maybe translation - I am not aware of any such problem beyond locale issues personally. You are correct, there have been other posts with similar issues - 1st I looked at was from 2022 - haven't really seen anything current. I'd venture a stab at your fonts - I don't have windows.

My PC is Windows 11 with Microsoft Defender.

Hi Harold, in your screenshot from this site, the local code "ka" is in the URL. If you delete that or change it to en-US (for U.S. English) and press Enter to resubmit, it should return to looking more familiar. I'm not sure why the server thought you preferred that locale; could you check your Language setting? See: Choose display languages for multilingual web pages.

As for the WSJ, that's hard to say. Especially without a subscription. But it could be that the site uses a custom font downloaded from their server which Firefox either isn't loading or isn't applying for some reason. Some users block "remote" fonts using a setting in uBlock Origin or other add-ons. Could that be a factor on your Firefox?

See settings...en-US

Could you click the Choose button to the right of "Choose your preferred language for displaying pages" and see what order is listed there.

If only the Mozilla Support site is switching to the wrong locale, that would be weird, but it's certainly possible. Try using the language selector near the bottom right of the page (above the Twitter YouTube and Instagram icons) to select English.

No luck. See screenshots.

That setting looks right. But if you use a general address for Mozilla Support (https://support.mozilla.org/), it still redirects you to the "ka" locale?

For the WSJ, could you check what font the site is using in that area? This involves using the Inspector tool, which hopefully they don't block. Right-click (or Shift+right-click) the problem text and choose Inspect. Firefox's developer tools panel should open with a diagram of the HTML of the page. On the right side, there will be one or two panels with details about the area of the page you clicked. Along the line with Layout Computed, etc., click Fonts. Sometimes this will require clicking a little triangle to access the full list. On the Fonts panel, Firefox should show the font details for the funky text.

See below.

Please note I have had this issue with several websites...including Mozilla and Costco.

On the WSJ, the site prefers the "Chronicle SSm" font and falls back to the browser's default serif font. Your Firefox indicates it is Bookshelf Symbol 7 and Times New Roman -- Times New Roman usually is the default serif font on Windows.

First, I don't know why Bookshelf Symbol 7 is referenced there. If you go back to the Settings page, Fonts section, Advanced button, could you make sure that your default fonts for both "Latin" and "Other Writing Sytems" are sent as:

• Serif: Times New Roman
• Sans-serif: Arial

Second, we should try to figure out why your Firefox didn't retrieve and use the "Chronicle SSm" font. I assume the problem on this site (which prefers the Inter font) is related.

On the other hand, Costco specifies a more MacOS-friendly font preference of "Helvetica Neue", Helvetica, Arial, sans-serif. In Firefox on Windows, "Helvetica Neue" historically looked like hollow outlines. Are you seeing that?

Webfonts Not Loading

(1) Allow pages to choose their own fonts

This checkbox is in the Fonts dialog mentioned above.

(2) Check for extensions blocking downloadable/web fonts.

(3) Check that Firefox is not set to block downloadable fonts:

(a) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

More info on about:config: Configuration Editor for Firefox. The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.

(b) In the search box in the page, type or paste gfx.downloadable_fonts and pause while the list is filtered.

Firefox should list about seven preferences; ignore the bar at the bottom with Boolean Number String.

(c) If the gfx.downloadable_fonts.enabled preference is bolded and has a value of false, double-click it (or click the Toggle button or Reset button at the right end of the row) to restore the default value of true

(4) If Firefox still seems to be substituting local fonts for web fonts, consider whether any external security software or proxy could be involved
