Pages load slow and get boxes instead of text
I upgraded to latest and not all my pages takes ages to load and when they do images are fine but txt is just weird small boxes.
Additional System Details
- Shockwave Flash 32.0 r0
- User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:67.0) Gecko/20100101 Firefox/67.0
Can you attach a screenshot?
- use a compressed image type like PNG or JPG to save the screenshot
Do you see little boxes with a hex code instead of the image?
Special icons are usually supplied by an icon font that is downloaded from the server via @font-face CSS rules.
You can check gfx.downloadable_fonts.enabled on the about:config page and make sure it is set to true (if necessary double-click the line to toggle its value to true). Also make sure you allow pages to choose their own fonts.
- Options/Preferences -> General: Fonts & Colors -> Advanced
[X] "Allow pages to choose their own fonts, instead of my selections above"
If you use uBlock Origin then check "block remote fonts".
If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (uBlock Origin, Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger) always make sure such extensions do not block content.
- make sure your extensions and filters are updated to the latest version
Firefox shows the shield icon at the left end of the location/address bar in case Content Blocking is blocking content.
- click the shield icon for more details and possibly disable the protection
You can check the Web Console about what content is blocked
- "3-bar" menu button or Tools -> Web Developer
I have removed all extensions, add-ons and plugins but still nothing. Attaching screenshots.
This looks like an issue with a corrupted font.
What font is Firefox trying to use?
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.
Attached a screenshot of the inspector.
I was able to fix the issue with the solution from the below link.
