Displays Strange Characters on some websites
On SOME websites firefox displays characters strangely while other browsers work fine. Screenshot attached. Sites are allowed to choose a font. Refreshing and deleting cache don't help. Any ideas?
It looks like the web page is not loading properly. Load the web page. Then, to reload the page bypassing the cache and force a fresh retrieval; Ctrl+Shift+R (Mac=Command+Shift+R)
Try this several times.
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. Also make sure you allow pages to choose their own fonts and that you do not block remote (downloadable) fonts.
You can right-click and select "Inspect Element" to open the builtin 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 Font 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.
