Firefox fails to use some local fonts

After installing the Native MathML extension (to get MathML typeset equations on the Wikipedia, as suggested on mediawiki.org), all equations set by MathJax/MathML turned to using STIX instead of Latin Modern. I'd like them to stick to Latin Modern instead.

The only possibly related setting I've found is `font.name-list.serif.x-math` in about:config, whose value is `Latin Modern Math, STIX Two Math, […]`. I tried to manually change the font family specification of some text to see if Firefox could use Latin Modern Math to begin with, but apparently it can't (see first screenshot attached), while it loads STIX allright (second screenshot). Latin Modern is not the first locally installed typeface I haven't been able to use, but it's the first one I have really tried to (I don't remember which one the other typeface was).

My Latin Modern font comes from TeX Live 2019 installed using the TUG installer, not Fedora's package manager. `fc-list | grep -i "latin modern math"` returns `/usr/local/texlive/2019/texmf-dist/fonts/opentype/public/lm-math/latinmodern-math.otf: Latin Modern Math:style=Regular`. I'm running Firefox 87 on Fedora 33.

When I go to https://www.sz-shop.de/ostern, FF tells me that there is a risk

"Warnung: Mögliches Sicherheitsrisiko erkannt ... Am wahrscheinlichsten wird das Problem durch die Website verursacht und Sie können nichts dagegen tun. Sie können den Website-Administrator über das Problem benachrichtigen."

That is what I did. I called that shop and told about that warning. The lady on the phone also went to the address, but she did NOT see that warning. She confirmed that her PC was OUTSIDE of sz-shop.de like mine.

So the problem is a potentially wrong warning? Or how can we explain that I see a warning and other people do not see it?

Hi all, I have an Apache site on Kubuntu 20.04 with a certificate signed by my private CA. I've added the root CA ceritificate in Firefox and in Chromium.

Firefox throws a SEC_ERROR_BAD_SIGNATURE error

Chromium accept the certificate as valid

What can I do?

Hi guys i'm new in the forum so i have no idea if anybody else allready had my problem,i've tried to fix it myself but i cant seem to get it done. Yesterday i had a problem with my OS linux,and i had to reinstall the system,while i was pretty sure i had all bookmarks saved in an external HD i went straight to a quick format and reinstall of the OS,after installed all the due system update.

The Problem:

While i was importing the bookmarks.html i stored in external HD i noticed that nothing was being added in the bookmarks of Firefox,so i tried few times just in case i was doing something wrong but still nothing was being added in the bookmarks,so i tried to import the bookmarks on Tor Browser and the same thing happened nothing was imported. So it came to my mind that the .html file could've been damaged. Now i tried many ways to open the file either in command line or text editor i even tried using libreoffice,in the case of text editor,command line such gedit,pico,nano it loaded the file but it was heavily encrypted,in the case of libreoffice shortly after i tried to open the file popped up a message telling me that the file was corrupted and libreoffice couldn't read it and stopped.

I need a solution to either fix the .html file or decrypt it so i can recover the web addresses inside and it would be very bad for me since my bookmarks.html is 3.3Mb large with ALOT of bookmarks inside.

Can anybody tell me how to?

Thank you in advance for any help or suggestion that may help me to retrieve my bookmarks. Ludo.

P.S. OS Linux BackBox 7 up to date along with it latest version of Firefox that update server provides me.

Hello dear community,

I recently switched to a dual boot system and got Ubuntu 20.04.1. If I want to watch Netflix for example I cannot because of DRM settings (at least the pop-up of Firefox says so). Other video and audio content is working fine so far. The guidelines on what to do to solve the problem like this

https://support.mozilla.org/en-US/kb/enable-drm?as=u&utm_source=inproduct

won't work unfortunately. Does someone have any other idea what to possibly do?

Thanks a lot for your help! -Jo

We have a new add-on of our own that we were trying to add to the Firefox browser. This add-on was tested locally and worked fine. However, upon trying to install the official add-on to the browser, it is throwing the following error, "Installation aborted because the add-on appears to be corrupt".

The add-on in question is, https://addons.mozilla.org/en-US/firefox/addon/searchgiggle-search/

Any suggestions to address this issue would be appreciated.

I also noticed another post or two about the same topic. As per those posts, the issue got resolved automatically after some time. Can I expect the same?
