having troubles with Comcast email obviously using FF 87.0 (64bit) after hours on the phone and the problem being elevated to what Xfinity said level 4 ....they tell me it is in my settings.......I can login fine in private browser.....lost as to why I cannot in my normal browsing mode....help

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.

Turned on my imac this morning and the Firefox browser gave a "Error code: SEC_ERROR_BAD_SIGNATURE" for every page I tried to open. I have reinstalled the browser and that one is working properly. However, when I try to add Dashlane to it, the old browser opens and the same error message is displayed making it impossible to use Dashlane on the newer version of the browser. How can I get rid of the version that opens up when I try to install Dashlane on the working browser?

I just upgraded to Firefox 87.0 (64-bit) for Windows 7. After the upgrade the wheel click to open a link in a new tab isn't working. In fact, doing a wheel click does absolutely nothing now. I have relied HEAVILY on using wheel clicks to open links in new tabs. In fact, depending on what I am doing I am more likely to open a link in a new tab than to just follow it, as it is easier to close a tab then hit a back button 4, 10, or 20 times to get back to where I started.

I have verified the following options in about:config; browser.tabs.opentabfor.middleclick=true middlemouse.contentLoadURL=false middlemouse.paste=false middlemouse.scrollbarPosition=false

When searching to see if others were having this problem I noticed a user from 3 years ago had this problem in the Linux version, and that they had listed an option for middlemouse.openNewWindow=true. This option is now missing from about:config. I have no idea if it was in the previous version of Firefox or not, or if it being missing is the source of my problem or not. I have restarted Firefox itself a couple of times, as well as rebooting my computer, the problem is still there.

At this point I am already highly tempted to attempt to return to the previous version of Firefox just to get this one feature back, simply because of how regularly I rely upon it. The only reasons why I'm not at present is to ask for help fixing this problem and that I probably won't have the time around work to fight with it for several days.

First and foremost, screenshots/snippets are captured by the Windows 10 "Snip & Sketch" and "Snipping Tool" software. I checked the settings for both and there are no settings (toggled on or off) that would fix the issue when tested.

ISSUE: Essentially, once the image is captured and copied/pasted into a Gmail email (ex. composing a new message) ONLY in FireFox does the image paste twice. However, the same process does not replicate the issue in Gmail in other browsers. And I am also cognizant of key strokes aka possibly doing a Ctrl+V twice on accident; that did not occur.

Is this just a minor bug that can be fixed with a FireFox update? I already cleared cache and cookies, de-synced/re-synced FireFox, uninstalled/reinstalled FireFox, and restarted my device. Please advise.

Recently, I opened up the Firefox browser and it prompted me to create a new profile. I reopened the browser 2-3 more times and the same thing happened. I created a new profile. My bookmarks immediately disappeared. When I went to look for my old profiles, they all had disappeared, also. Firefox has been updated recently, and so has Windows 10. I have an older (2013) Toshiba laptop. Any suggestions for getting profiles and/or bookmarks back?

Do Firefox's title bar buttons change depending on custom Windows 10 themes (I hope that made sense)? Whenever I choose a custom theme (from DeviantArt) those buttons look out of place, any way to fix this? I only have this problem with FF The theme is this -> https://www.deviantart.com/kdr3w/art/Gray-Dark-807271550

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?

All of the add-on icons in the right-hand corner have disappeared. I want to have them back. But turn on, turn off toolbars doesn't fix anything. Customize toolbars doesn't show any of the icons. There's no help for this that I can find; it's hard to even find the terminology in order to describe it. Add-on bar? Is it turned off or hidden or nonfunctional?

I am unable to download anything using Firefox. I have tried everything listed in this article: https://support.mozilla.org/en-US/kb/cant-download-or-save-files

Nothing has worked; starting in Safe Mode; clearing my cache; disabling all addons; disabling my firewall; disabling my antivirus; even reinstalling.

I can download using other browsers just fine, but not Firefox for a reason I cannot figure out.

Hi,

I had to delete all my profiles and completely reinstall Firefox because Firefox was not changing the color of previous websites to purple no matter what I tried. I thought I could delete the profiles and create a brand new one to start over fresh.

After reinstalling Firefox (latest version) I have run into a problem where under <about:addons> <Plugins> it shows a yellow box and an error saying "Widevine Content Decryption Module provided by Google Inc. will be installed shortly".

This message won't go away and Widevine will not be installed at all. I cannot browse and Netflix, Hulu, HBO Max etc.

I have tried unchecking and checking the <Play DRM-controlled content> under <about:preferences> which does not work.

I have also tried going to this (link)link and manually installing it but the webpage for my OS's .zip file won't load for me.

Hello, I would like to log out remotely from the Firefox browser that is installed on another device because it automatically logs in to all websites that I have visited frequently. Among other things, it is a discord where I value privacy very much and I do not want any person using the laptop (because there is no password and the device is also used by other people in the family) to have access to the account. First of all, I want to log out of the browser (i.e. simply log in again to just protect my data). This need came to me because the website (I closed the discord and I am 100% sure of it and it shows me that it is open all the time). I apologize in advance for the spelling because I translated myself with a translator because I do not know English very well.

Hi, guys
Get this message in pop-up window. How can I fix it?

Es wird immer gesagt "Bitte geben Sie Ihr Hauptpasswort ein. In English: "Please give your main password". As I don't have a pin I cannot complete the task. Could you please help me?

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.

Gmail seems to be the worst site. Alphabet letters and numbers are missing from words and dates in subject lines. Same in the left folders column. Elsewhere, photos will not display properly. I'll only get bits of an image. Refreshing may resolve the problem momentarily but then it reoccurs. I reinstalled Firefox, but that didn't fix the problem.

This is said about master password: Important: After you have defined and set your primary password, you will be prompted to enter it once for each Firefox session, when Firefox needs access to your stored passwords. This also applies if you want to add, remove or show a password.

I think that "when Firefox needs access.." should be changed to "regardless if Firefox needs it or not".

It would be much better if the master password promt was delayed until the first time it was needed.
