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?

My computer was updated with the latest linux and the latest firefox browser. I want to create folders in my bookmarks. All the help answers say to go to Bookmarks and click on 'Menu'. That does not come up as an option. All I get is: Show all bookmarks; bookmark this page; bookmarks toolbar; other bookmarks. I can't find anything similar in tools, edit, or file. I also don't get 'Edit Bookmarks' like was in the last edition I had.

Hi,

searching for bookmarks (with sidebar) is no problem. There are several cases where I look, if something or similar had been bookmarked already. With this I want to avoid doubling/tripling/'moreling' bookmarks. But if I find something already bookmarked, I do not know in my about 1000 bookmarks where the bookmark is located. I tried to show properties of the found bookmark but it does not tell where it is placed. So I would have to look manually about 100 folders to find where the bookmark is located.

The most easy solution I think, would be indicating the place of the bookmark when showing settings of bookmark. On hovering over the found bookmark in a third line of popup could be told the location of this bookmark and would be visually more pleasant I think.

Else I have to put the bookmark doubled in a more visible location and delete the bookmark found by search. This workaround works but is not intuitive and bothersome (and costs much more time).

As this solution would be easy to implement, I hope, this can be implemented 'soon'. I think, this would help many others, too. (At least I heard from several others in my environment, that they miss such a thing.)

Not forgetting, thanks for the great browser, Niels

a similar problem in a browser installed with apt (but when running in safe mode, there is no problem, and manually disabling extensions and cleaning / refreshing firefox, does not help). When installing via snap, there is no such thing, but it does not suit me for work, since there is a problem with profiles.

I would be very grateful for your help in solving this problem.

Hello, how can I get similar functionality to "New tabs" as I have for "Homepage and new windows"? Because right now all I can do is either choose to open Firefox's home page or a blank page, but I would like to be able to open my custom sites just as I do for "Homepage and new windows".

Firefox version 87.0

Ever since I signed up for Firefox sync, I have been berated with emails from them asking me to sync more devices. I really do not want to receive marketing emails from Mozilla and there is no unsubscribe button in the email. How can I stop these emails?

I am having issues playing back video on certain sites using both FireFox Developer edition and Regular Fire Fox

FireFox Developer edition: Version: 89.0b4 Fire Fox: Version 88.0

Sites I have having issues with - Hulu - Twitter - Discord

These sites work with Google Chrome but I really don’t want to have to use those sites for video play. Any help would be appreciated.

Operating System: Manjaro Gnome Linux Graphics Card: NVIDIA Ge Force gt 1030

Introduction So I learned the hard way to never run sudo apt remove python3 on an ubuntu system. I'm running Linuxlite (Ubuntu 20.04.2 LTS) on a dell desktop (unsure of the model).

The Problem After looking at some guides and upgrading the operating system, I managed to get most of the fonts to display correctly. Sites with certain kinds of text still appear to be "too bold" (see images).

""What I've tried"" The command actually removed Mozilla, so I had to reinstall it. Updating it also didn't fix the problem. I have messed around with the font settings and nothing changed. It seems that only Mozilla is doing this because the Brave browser displays the fonts correctly. Other than that, I haven't really done all that much. Also the font as I write this is normal.

Thanks for your consideration!

Ever since installed Ubuntu 18.04.5 LTS (& latter upgraded to Ubuntu 20.04.2 LTS), I am unable to watch YT live videos! Below are the screenshots of the issue & a test page report.

I have a problem with enabling two-step authentication for my Mozilla account. There have been several questions regarding issues with two-step authentication, but none of them applies to my case, so I started another one.

When I try to enable 2SA, there are seemingly no problems. When I scan the QR code and enter the 6-digit security code, I don't get the "invalid two-step authentication code" message. I do get the 8 10-digit recovery codes. After I enter one of them I get a prompt saying "Two-step authentication enabled" (see attachment), but nothing else happens. It seems like the process is stuck here and isn't completed.

I have tried setting 2SA from my profile settings (https://accounts.firefox.com/settings) too, but when I logout and login again, it says Not Set.

I wouldn't normally use 2SA at all if it hasn't been made mandatory for logging into Add-ons (addons.mozilla.org). Now, I'm locked out of my Add-ons account and can't access my extensions!

Moin, I activated the HTTPS-only mode as I used the "https everywhere" plugin so far.

But, in a very special network segment for radio amateurs, the 44-network (ampr.org) encryption is not allowed. So is there a way to configure the HTTPS-only mode in a way to say ".... but not for 44.0.0.0/8?

i prefer one configuration than constantly clicking the "continue to http site" button for the next few years.

Thanks in advanced

Hi, a few days ago, the cursor began to appear in the elements of a web page and it is a bit annoying, has it happened to someone? I already updated and reinstalled but it was not solved.

Thank you!

Bonjour, depuis plusieurs semaines j'ai des bugs graphiques sur l'interface de Firefox et sur les pages web. J'ai attendu en pensant que ça passerait avec une nouvelle mise à jour mais rien ne passe. J'ai testé le mode dépannage et le mode réparer Firefox, le problème persiste.

I have Firefox home with a search engine as home page, but since the update to 89, when I try to type into the search box, it jumps to the address bar. This is very annoying. Can it be fixed? I do not want to use the address bar this way. I found a help that said to open the application menu and click "customize" but there is no "customize" option there. In the attached photo, I clicked in the search box to place the cursor there, but as soon as I began typing, it jumped to the address bar. This has never happened to me before in the 15 years I have used Firefox. I am a recent convert to Linux (about 1 year now) and am using Mint 19.3, Cinnamon 4.4.8, if that makes a difference.

When you click on the address bar a drop down menu appears which allows you to immediately select a site that you visit frequently. How do I remove an item from this menu?

Some solid colours on certain webpages do not appear whilst on Firefox. The background will show up instead of the colour the image should be. I have tried to delete the cookies and cache on Firefox as well as trying Firefox in troubleshoot mode to no avail. Whilst writing this question, I have also discovered that taking a screenshot of the issue shows how the image should look as opposed to what the screen shows. Attached are some images of the issues I am facing, two images are of what appears on the screen and one image is the screenshot from the webpage which is what should have been shown. Apologies for some of the photos, I had to take a photo of the screen with my phone to show the issue. I have also closed the browser multiple times and restarted my computer, any help would be appreciated. Thanks in advance.

Hi,

I'm using Firefox 89.0 (64 bit) on Lubuntu OS via Mozilla Firefox for Ubuntu Canonical - 1.0.

Despite selecting Restore previous session in settings, and quitting firefox using Ctrl-Q, firefox does not restore the previously open tabs. I have to click on history -> Restore previous session for the tabs to load.

This issue started recently. Please fix the bug.

Thanks, Ajit
