In the attached image you will see the text, "chevron_left" and "lock_open" which are the names of glyphs that are supposed to be displayed in those positions. This text obscures the actual text of the web-page. It should not be displayed. What do I do to get the glyph to display instead of its name?

Hi, I tell you that it is not an error that depends on firefox, it is attached to the website you are on.

But you can try this: https://support.mozilla.org/en-US/kb/how-clear-firefox-cache

I'm not sure what site that is, but I generally see those phrases when a site is using Google's "Material Icons" font, and for some reason that font is not loading.

Here are some of the reasons the font file might not be loading:

(1) Firefox set to always use your preferred fonts instead of the fonts specified by the page (2) Font downloading ("remote fonts" or "web fonts") blocked in an add-on (3) Google sites like gstatic.com blocked from being used in non-Google pages (4) Font downloading blocked in about:config

For #1:

Open the Options page:

  • Windows: "3-bar" menu button (or Tools menu) > Options
  • Mac: "3-bar" menu button (or Firefox menu) > Preferences
  • Linux: "3-bar" menu button (or Edit menu) > Preferences
  • Any system: type or paste about:preferences into the address bar and press Enter/Return to load it

Scroll down to the "Fonts & Colors" section and click the "Advanced" button.

Then make sure the box is checked for "Allow pages to choose their own fonts, instead of your selections above":

Any difference (you would need to reload the problem page, Ctrl+r or the circling arrow button, to see any difference)?

For #2:

For example, uBlock Origin has a setting to block "remote fonts". I'm not sure about others.

For #3:

If you use add-ons or container tabs to restrict where Google addresses load, you might need to make an exception.

For #4:

You can check here:

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

(2) In the search box above the list, type or paste gfx.down and pause while the list is filtered

(3) If the gfx.downloadable_fonts.enabled preference has a value of false, double-click it to restore the default value of true
