Hello Chintan, try clicking the menu button on the top right of your Firefox browser, then clicking "Settings". You will be brought to the general settings page so please navigate/scroll to the "Language and Appearance" section. At the "Fonts and Colors" section, click "Advanced", and then check if the "Allow pages to choose their own fonts, instead of your selections above" checkbox is unchecked, then check the checkbox. Hopefully that will solve your issue!

[v56+] Type about:preferences#general<enter> in the address box. Under fonts and colors, press the Advanced button. Scroll to the bottom, turn on Allow Web Sites To Choose Their Own.

Make sure you haven't enabled a High Contrast theme in the OS settings.

  • We have seen reports that this can be caused by a problem with fonts like Roboto or Helvetica that

you have installed locally and that might be corrupted or are missing some variants. Also, make sure you allow pages to choose their own fonts and that you do not block remote (downloadable) fonts.

  • If you use uBlock Origin make sure not to "block remote fonts".

Thanks @FredMcD & YongHan for support, 'Allow Web Sites To Choose Their Own.' was on by default. I have tried to remove Helvetica font from the PC but it always shows Fonts are in use - can not be deleted.

Any other way to the delete font ?

Or to solve original problem ?

You can check in Font Book for font issues like corrupted and duplicate fonts.

You can right-click and select "Inspect" to open the built-in Inspector with this element selected.

You can check in the Rules tab in the right panel in the Inspector what font-family is used for selected text. You can check in the Fonts tab in the right panel in the Inspector what font is actually used because Firefox might be using a different font than specified by the website.
