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.

Hello,

I have been getting a problem lately where nearly all the text on a couple of websites does not display. Only a few characters, such as 'T', 'E', 'L' and '4' display. I have attached screenshots of one of these websites - how it displays in Firefox vs. how it displays in Google Chrome. It also happens in the chat function of the online lecture video system my uni uses (Blackboard Collaborate Ultra), which runs in the browser (it's not a separate app).

I did a search for similar problems on mozilla support and tried restarting Firefox in safe mode, however nothing changed.

I'm using Firefox 78.12.0esr on MacOS X 10.11.6

Any help would be appreciated.

So, first off, Firefox is my favorite browser. I love it a lot. I'm also a pretty big supporter of Free and Open-Source Software.

With that said, I was wondering when and if Firefox will fully support ICC V4 profiles and the PNG specification.

I noticed that ICC V4 is not enabled by default, but even after setting gfx.color_management.enablev4 to true and setting gfx.color_management.mode to 1, ICC V4 is still not working properly.

You can test this yourself here: https://littlecms.com/blog/2020/09/09/browser-check/

Also, I noticed that PNG images of large sizes won't display at all in Firefox, resulting in a broken image icon.

You can test this yourself here: https://www.jwz.org/blog/2018/07/png-antics/

These seem to work at least passably well in other browsers, but I don't want to use other browsers! Does anyone know if Mozilla will fix these sometime? I do know that Little CMS is open-source under the permissive MIT license, so maybe Firefox could use that to fix the ICC V4 problem, if that could help. I don't know if using the latest version of libpng will help the other problem, but I know it is under a rather permissive BSD-style license.

I'm using Firefox 90.0.2 in case anyone is wondering.

In the last several days I have been unable to drag any tabs into a folder or other location to turn it into a bookmark. There are workarounds for this but they are much more complicated, inaccurate and time-consuming*. Similarly – I can't drag the folders around in the bar that they live in any longer. I feel as if some major interface change has been brought about, and it makes using the browser much more difficult. Can someone help me with this? I've lost a great deal of functionality and it's very frustrating.

  • as an example, I can use the bookmark tab option but then I have to navigate to the general area I want, drop it and then find a way to manually put it exactly where I want it. I used to be able to simply drag a bookmark to the desired location.

The appearance of my toolbars and tabs has changed a lot without my permission. How does this happen? It has confused me a lot and is no longer as easy to use, in fact it has become a burden trying to figure out how to navigate each window / tab I have open. Ex: some things that were in my toolbar have disappeared. Also, there used to be a pair of vertical arrows I could click once to zoom in or out. Now it has disappeared and I have to go up to the main FF menu then click View then click Zoom then click one of four menu items. This is nuts and adds several more steps to what used to be one simple step. WHY???? I have not downloaded any new recent versions of FF and yet all these changes were made anyway without my knowing it or asking for it. How can I get back to my former version that I was happy with?

Today is the first time I noticed a red fence icon above the box where I type my email address to login to the website where I do my work as a bookkeeper for a property management company. When I placed my cursor on the icon it said, "If you use your real email address here, Facebook may be able to track you. Click to learn more." See attached screenshot. But, clicking did nothing.

I'm pretty sure I'm safe since the email address I use to login to work is different from the one I use for Facebook, but could someone please shed more light on this?

Apologies for re-posting, I asked about this issue before https://support.mozilla.org/en-US/questions/1323826, but it was archived without any response :(

In an answer to this question: https://support.mozilla.org/en-US/questions/1318109#answer-1376159 cor-el warned that using OS authentication (for example, TouchID on a Mac) for passwords instead of a Primary Password is actually not really safe because it doesn't encrypt logins in logins.json and it would be possible to extract them by running: prompt("Logins",JSON.stringify(Services.logins.getAllLogins())); Now I am a bit confused because for storing Credit Cards the default is, of course, using OS authentication (I don't think there's an option to set a password instead). So I am wondering, is that safe, i.e., is the credit card information encrypted that I can retrieve with my TouchID (even without a Primary Password)?

And if so, would anybody be able to explain the differences between these two approaches and why the Firefox developers chose one for Logins/Passwords but the other for Credit Cards.

Firefox 90.0.2 macOS 11.5.1 Facebook Container 2.3.1

I work with an organisation which is using Workplace (https://www.workplace.com/), a "social media" site owned, managed and run by Facebook. If you aren't familiar with Workplace, it is a business-oriented site to allow organisations to communicate internally - Facebook trying to improve its image?

Except although Facebook Container recognises it as a Facebook site, it breaks the specific site (https://citizensadvice.workplace.com/) my organisation uses. And neither can I place this site within Facebook Container.

I really don't want to turn off Facebook Container everytime I access this particular site, several times a week but I don't want to open myself up to tracking by Facebook.

Ideas or suggestions for resolving this problem?

Thanks
