Firefox Support Forum

I've been browsing some coding sites to learn a bit and I've noticed that the text boxes they use to display the code or the way they format it, is not showing the numbers properly. Like how sometimes instead of 3 it'll just be A and zeros don't show. Commented code seems to fine.

Hi. Text on my Firefox suddenly turns into solid coloured boxes. This problem has started only recently and is happening only of Firefox. I have not made any changes to my PC recently.

Hi there,

I've just downloaded the dev version of Firefox, and for some reason some of the text defaults to italics; I can't see where to change this. On all other browsers, this text is not italic.

Does anyone have an explanation / solution?

The non-italic text in the picture attached is the 'good text' which accurately reflects itself accross browsers and devices. The italic text is the 'bad text' that I want to change for consistency.

Thanks!

The font displayed in gmail won't change using the firefox browser. It works fine in other browsers. I tried to select sans-serif normal size and it stays with a serif font and small size.

My title bar has a weird symbol in front of where it says Mozilla Firefox

Sort of looks like a yen symbol and the m of the Mozilla Firefox looks weird as well

Posting on mobile devices other wise would attach photo

It's probably something I did to myself. I never had it before, but I did a clean install of the latest version and now I have a layer of type on top of a layer of type (see attached screen shot). Now I already have slight double vision in my right eye, so this new phenomena isn't helpful, but it's not my eye,. both eyes see the two fonts in use overlaid.

It probably is caused something I did wrong???

I've looked around and I can't find it; it may be hiding in front of me, but I've looked through settings several times and nothing pops out as something that would result in this. Any suggestions?

To me it looks like two different fonts and sizes. It does make it more difficult to surf.

Thanks in advance, Dean

Hello,

I have a problem displaying fonts in FireFox. At some websites they are badly readable. In Chrome I do not have this issue. I already browsed several solutions. If I switch off "llow Web Sites To Choose Their Own" it works for the website in the screenshot that is then correct (same as chrome) but other website (like ads.google.com) then have problems.

Safe Mode did not make a difference.

Also I tried this "exe" file to set windows font, which I forgot the whole file name. Also did not work. I have it not only at one website but it happens more often.

I use the most recent FireFox for windows 93.0 (64-bits) The website as an example is https://www.retourplaza.nl/152006-broodbakmachine.html And then any PDP (product detail page)

Image FireFox with bad readable font on top. The chrome one is the bottom picture.

As written I have it on more websites.

Thanks for helping out.

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?

This has happened on several of my computers. Upgrading from some version of FF80 to some version of FF90 results in gibberish text.

What Mac OS system fonts does Firefox require? I somehow got this fixed on one system, but many monthds ago, so I don't know what actually worked. I have cleaned font caches, etc. but cannot get it fixed on the latest so far. Settings are Latin, normal fonts like Georgia or Verdana.

How do I enlarge the font size in gmail? It was suddenly much smaller when I opened it a few days ago. I enlarged it to 18 in Preferences, but when I tried to increase the percentage of enlargement from 133%, it went back to the smaller size. Then the window for increasing percentages disappeared. I see a lot of people are complaining that their font size also spontaneously changed, usually to a smaller size. I am also visually impaired, so this is a real problem.
