Firefox Support Forum

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?

I use windows 10, use firefox for months and now i dont know why it's crash. It do not open. I try to reboot no result, try to use installer once again with too no result. How can I fix this?

This morning I closed my bookmarks sidebar to frame open windows better. Now there is no option to restore it. Help please, as this is my best organization for web browsing. Thank you!

EMAIL DISPLAY IN GMAIL: Hello. All of my emails open the first page okay, but an increasing number of action pages in emails do not open. Those pages contain forms to fill out, petitions to sign, and donations to make. This problem began in late February/early March (FF 86&87).

The tech support at EveryAction.com said she thought they need Javascript to open, but I couldn't find any setting or add-on in FF to enable/disable Javascript. I don't know why all of their action pages have been opening fine for years--maybe it's related to FF's new versions. I tried adding Policy Control because it supposedly enables/disables Javascript but it didn't solve my problem.

The tech support at Earth Justice wrote this in response to my report about their action pages not displaying: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:87.0) Gecko/20100101 Firefox/87.0; https://earthjustice.org/action/investigate-troubling-payments-that-threaten-the-florida-panther?contactdata=8D8RgJTCUXwiDCjeWPHh7wQ1fwDy7YSqjRoUFBMLj9iH2tXUofJiQ1CKU%2fIhkHfdjY8KsFkiYme4BhD4yp%2bpJ9S13ALo6NdUs4CtwLA2KaAhIZ0GP2%2bWq9ZUYNwtkHNEKC%2bxUF4VNRJ1XirXG00WayYuwLGnnHVzRWtCwf3s%2fqtR64TlcMwKx0w2e3AyPLspJ8xDw1TQNs%2fSBpWztf%2fNBkvDKFTrC6fsKAvY54zt13IfVVPcfU%2byEdneTMzDaYIN&ms=email&utm_source=crm&utm_medium=email&utm_term=action&utm_campaign=2102_Action_Panthers_Haaland&%3butm_content=HTMLTakeActionButton1&emci=5a0f473e-c881-eb11-85aa-00155d43c992&emdi=01870d6d-d68b-eb11-85aa-00155d43c992&ceid=962627 "We are still investigating this problem, but it appears to be concentrated among Firefox users. We do know that our EveryAction forms require Javascript to be enabled, so if it’s disabled and you’re able to enable it that might work and would be helpful to our efforts to sort this out. Let us know if you’re able to get that to work, and thank you for your patience."

I would be very grateful for your help in solving this problem. I'm sure there are other users out there with same problem. Thank you. --Sincerely, Bo Bergstrom.

Dashlane Password Manager has been working as an extension on Firefox on my Acer Aspire E5-571 laptop, but for an unknown reason it has disappeared from my toolbar. When searching for 'Dashlane' on the Firefox browser to install the extension on my browser, nothing relating to 'Dashlane' can be foound.

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.

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?

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.

Firefox keeps going unresponsive after 10 to 30 minutes. I tried creating a new places thing. It didn't work, and oddly still let me restore my old session and kept my bookmarks, which it said I'd have to re-install. I'm only running two extensions, U-block and NoScript. It will go Unresponsive, remain so far minutes at a time, briefly return and then immediately go unresponsive again, just long enough for me to close a tab or shut down. Nothing I have done seems to fix this. I am on the latest Windows 10, Desktop, latest Firefox.

I can not press the "Backspace" on YouTube using Firefox, but my keyboard works fine cause in Chrome and Edge it works perfectly, I've already refreshed the tab and still not working. Have any idea of what's going on?

Hi, I have a probem. My PC broke down. I lost all my data. After i reinstaled Firefox on my pc and Connected it to Sync, i was not able to get my bookmarks back. I see them on my phone under - Bookmarks - Desktop Bookmarks, but i can' t see them on my PC. I tryed to sync them, but nothing. I remember that when this happened last time, i just loged in and got all my bookmarks back, but now i have lost half a day, but got nothing out of it....

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.

I recently upgraded to Windows 10 and MS Office 2019 Professional Plus and need to re-install a lot of stuff. I want to download Firefox to use as my default web browser. When I download and install, the icon shows up on my desktop all right, but when I click the icon to open the browser, the tab says "Problem loading page" and displays "File not found" error message (screenshot attached here).

Does this have anything to do with the "Sync" option that keeps popping up? I don't know what that means, except it looks like it wants to "sync" my computer with my phone or any other devices, which I don't have any interest in.

Please help! Thank you!

Is it possible for Mozilla Firefox to develop a feature that can delete downloaded files directly within the browser, like Edge does?

First of all, thank you for browsing and answering! Whenever I download a file by mistake, I have to go to File Explorer to delete it, even though Firefox can locate the downloaded file directly, but this still wastes some time. So to save time, can Firefox also introduce an option to delete a file after right-clicking on the downloaded file, just like Edge?

(New to the Firefox community, so please don't overly accuse me if I'm wrong)

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.

The "View History Sidebar" command is missing from the History menu after updating to Firefox 87. Is this a bug or was it intentional? The Bookmarks menu still has the "View Bookmarks Sidebar" command.

While I found it possible to work around the issue via Customize and adding the "Sidebars" control, this is quite unintuitive and awkward to have to use two different buttons in order to access your history. (IMHO, the History menu should just show the full history to remove the need for the sidebar, but that's a separate discussion.)
