I just installed Firefox to my laptop and noticed that Japanese characters are not working. I tried to change the language from english to japanese because I thought it would install the characters but didn't work and rolled back to english. I need to read japanese texts in webpages.... I also checked text decoding from settings > more > text decoding. Unicode is selected and I cannot change to anything else, it is unselectible. What should I do to be able to use the browser properly?

On some websites the fonts are all displaying in a large bold text instead of whatever font that page is meant to use. It will revert to a default font if i turn off the ability for sites to choose their own fonts, but this interferes with the functionality of a lot of sites' icons so its not a great solution. This also stops when i go into troubleshooting mode, but when i went through hardware acceleration and my extensions one by one, none of them were the cause.

images in order: my roll20 homepage with the incorrect font display, the same page with fonts disabled (note the notification icons in the upper right are broken now though), the same page in troubleshoot mode with the correct font display

When I open a website using special symbols, the symbols are replaced by a sign with 6 hex symbols in it.

It even happens when the symbol is used in the page title (see image). Site used: https://emojipedia.org/yawning-face/).

Interestingly, other emojis from the same site are displayed correctly (means the '01F971'-type symbol is replaced by the emoji, in all occurrences on the site and title)

I have seen multiple threads about this, even on this site. However, I could not solve it with the suggested solutions. What I have tried so far:

1. Disable addons 2. Make sure fonts are downloaded through settings 3. about:config -> gfx.downloadable_fonts.enabled -> make sure its true (4. no-script is not installed)

Any ideas?

I've read some complaints about the font that FF desktop uses on some websites. I'm seeing a very annoying font with some letters thicker (almost bold) and other letters thin. This occurs, for example, on the mozilla.org website and when FF is displaying a PDF.

I have "allow pages to choose their own fonts" checked, and I am not using hardware acceleration.

I went into the developer console and turned off the Mozilla-supplied font for a support webpage, and it then used something like a Times New Roman, but it was uniform in letter thickness.

I have attached screen snips.

If I display the same page using Chrome, the font looks great, so I don't know exactly what the problem is, but it's clearly a FF problem.

Notice in Chrome that the word "garbled" is in bold, and it does not appear in bold in either of the FF font examples.

Noticed a weird problem - some sites don't render their fonts, just empty space in place of text.

Tried to debug it: 1. Safe mode and disabling hardware acceleration doesn't fix it 2. Sandbox values don't change anything 3. Tried other Mac with the same Firefox version and macOS version - same issue 4. Experimented with CSS in dev tools - issue is related to the specific font (InterVariable in this case, also saw it with OpenSans before).

As you can see on screenshots - we have InterVariable font for this specific block. If I change CSS and remove this font, replacing it with some other one like Roboto - font starts rendering fine. Interestingly enough - font preview in the dev tools works completely fine - font renders, it just is not rendering in the page itself.

As it is a Variable font and me having older MacOS 10.11 - I was suspecting that it is a bug with Variable font support, but why does it render in dev tools and why doesn't it fall back to the other supported font, if this one is not rendered?

Disallowing pages 'to use their fonts' obviously fixes it - as it activates fallback to fixed fonts, but it is not a proper fix, as it obviously messes up designs for sites and their custom fonts.

This side renders completely fine in Chrome, so it must be a Firefox issue. Upgrading macOS is not an option, so I would be fine with a fixed ESR version that works correctly.

Attaching screenshots showing debug info.

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.

Hello,

It is not the first time I got that error. I have no idea why.

When I want to start Firefox, this blank window appears (see image). When I click the button or close the window, nothing happens except the window being closed.

I tried to reinstall Firefox, and the autolaucher after the installation opens a Firefox window but, if I close it, I see the error window again when I try to open the program later.

I tried to reset the taskbar's shortcut with the new-one-time-only-working-window-following-the-reinstallation but this did not work.

Please, check for this error. I can not just wait for the program to be ok to run without any logical reason/explanation.

So recently, when I open web pages, any numbers will display sideways. I reinstalled firefox, but this did not resolve. They appear correctly in other browsers (i.e., chrome). Does anyone know what I can do to resolve this? Thanks!

Can anyone help me with a master password issue?

The box appears at the appropriate time but I am unable to enter any text into the box. I point and click in the text space but the cursor does not appear and nothing happens when I start typing.

The sign in button is grey although I can click on it and the box briefly disappears then reappears asking for the password again. The cancel button works and closes the box.

I do not have the same problem on my Android mobile and I can access my passwords on my phone but not on my Windows laptop.

Thanks in advance, Grant.

Hello, since quite some time now, I've got a problem with some websites, https://www.20minutes.fr/ among them. With other website, it's all good.

In safe mode, the display is good, but I can't seem to find the responsible for this problem. Here's two picture to show you the problem. It's the same article, one in safe mode, the other one in normal mode

I've tried to run Firefox without any add-on, but, it's the same. My é and è, and à are gone... And it's not on every website, just a few ones.

I've also tried to clean firefox, the problem remains.

Thanks in advance for your time.

the new 89.0 firefox browser has changed the font to be thinner & lighter. although it is elegant & attractive, it is much harder to read. how do i make the font thicker & darker?

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.

Hello there. I have a 'funny' problem since last night. Fierfox in default mode is unable to display Ä Ö Ü on certain websites. It's a fresh installation without any Add-Ons. When entering troubleshooting mode it can display it. So the thing is: something is altering the displaymode of websites betwine modes.

where do I find the variables that do this in the config - or worse in the registry?

When visiting sites such as the Russian Wikipedia, characters that are in the Cyrillic Times New Roman font display as blocks (shown in image). Safari does not have this problem.

For the last few versions of FF (currently on 88.0.1 (64-bit) OSX Big Sur) certain websites display text incorrectly where the text is bold and each character is offset with the next one (see attached Images).

It only seems to happen to certain websites and happens both within my web based email and on standard websites - but only some of them.

I've attached a photo of the issue in my webmail - I'm viewing an email sent to me using mailchimp, but even this is inconsistent as other emails using mailchimp are fine. And as I said before it happens on websites too (examples attached).

I have this issue on my 2020 iMac and my 2020 M1 MacBook Air but not on my 2019 iMac. All 3 are running latest version of FF and all synced to my FF account and have all the same settings. Attached photo of plugins/extensions installed too.

Please help me fix this it's so frustrating!

Thanks

Since the last (?) update, sometime in the spring months this year, Firefox has not been able to display website fonts correctly. Often times part of the fonts turn to question marks, and the problem just turned even worse: even sites that I use regulary turned to complete mess – ALL TEXT. What the hell is wrong?

And NO, preference settings have no effect whatsoever.

Hi, To start with I love your browser been using and recommending it for many years. I am a service provider and have a customer that started getting this in her Firefox browser. Started a few weeks ago. Hard to describe the attachment will show more. There is a image box link. No image shows in any of them but clicked on it does go to the url. The url address is right after it. They are partially imposed over part of the description of the web site. Now my Firefox browser on my machine does not look like this. Is this a setting I need to disable to return it to normal and remove this little image box at the beginning? Or is there a problem with the browser? Thank you for your time and help. SEBassman

Hi, i have font rendering issues on some websites.

I found out it has something to do with the Hardware Acceleration.

When I turn it off, everyting is ok.

However, then other websites which require more performance are really slow.

How can I fix the big without turning off hardware acceleration?

This website among others causes font issues with hardware acceleration ON:

https://www.lazada.vn/

Certain websites font's have gone weird in Firefox, it's not reproducable on other computers just my own.

I have looked through this community and run through:

   Set gfx.canvas.azure.backends & gfx.content.azure.backends to direct2d1.1,skia,cairo
   Set gfx.font_rendering.cleartype_params.rendering_mode to 0
   Set gfx.downloadable_fonts.otl_validation to true
   Disabled hardware acceleration

Firefox Version is: 90.0.2 64-bit Windows 10 21H1 All drivers are up to date

Attached are screenshots from Chrome (what the website is meant to look like) & Firefox - I prefer Firefox over Chrome so I would rather not move.
