当我用旧版和新版火狐浏览器64位最新版，浏览http://www.urllib.cn时就会跳转到一个色情网站， 当我以https浏览https://www.urllib.cn确是正常的， 而我网站开启了强制https访问，为什么用火狐浏览器没有用https访问我的网站， 而我用，edge,谷歌浏览器，却不存在这样的问题， 官网能给一个合理的解释吗，

Bonjour, ce matin 2 juin 2025 j'ai vu qu'il était possible de faire des recherches en changeant uniquement le moteur de recherche qui figure sur une liste. Mais je suis incapable de trouver la page de Mozilla Firefox qui s'est ouverte en premier AVEC MA CONNEXION INTERNET CE MATIN COMMENT PUIS6JE RETROUVER CETTE PAGE ? Cordialement Dominique

I know, sounds stupid, but it is what it is. It happens rarely, only with Firefox on the secondary display from my laptop, via HDMI. It starts with some random few thin horizontal bars across the window itself, and soon, it turns off my display. It seems the bigger the window is, the more severe the issues. So full screen usually, it shuts it off and keeps it off. Not black screen, no signal style. I manage to get it out by Winkey+arrow. If i then put it back same issue. If i lower the width of it, it manages to stay coherent longer, but still resets the display with a quick black screen on page reload. The lower bounds on a 1920x1080 display resolution was 1515 pixels. At 1515 pixels, it works fine, once this is triggered, it's very repeatable on 60-70% of webpages. If i drag another window on top of Firefox, the monitor comes back up.

Before anyone asks: I have tried turning off hardware acceleration. I have tried putting firefox.exe to run on the integrated video card and on the dedicated 1060 Max Q videocard. I have cleared cache and etc.

This persists on a Windows session, across multiple Firefox restarts. A computer restart technically fixes it but i have no clue what triggers it. Laptop monitor works fine.

My firefox on my Mac will not open in full screen mode. It use to open in Full screen, but now no matter what I do when I close it out then try to reopen it, it opens in half screen mode. I set it to full screen mode in the setting but no luck. I tried deleting it and re-downloading it. I tried every tip online but nothing works.

Are their any plans anyone knows off to create a version of Firefox that supports the ability to use FileSystemAPI on directories.

The current one won't work with a BeatBuddy project and SD cards that are saved on my computer using their online editor - https://bbmo.singularsound.com/ - which forces me to use another browser for that...

I read the The Times in the UK and have no problem viewing on my iPad and Google Pixel phone using the Firefox browser. However on my laptop using Firefox I get a screen that says Secure connection failed and recommends contacting the vendor as there is no workaround. On microsoft Edge there is no problem I like Firefox but for me this is a major limitation. Any ideas or suggestions welcome

I cant get the browser to add bookmarks and the "For quick access. place bookmarks here....." doesn't go away All of my bookmarks I had before are gone too. But i don't care too much about that i jut want that message at the top of the screen to go away an i want to be able to add new bookmarks. Can you help me?

Free youtube downloader wants my age from Firefox to download popular music videos. I am logged in to FireFox and Free YouTube downloader identifies FireFox as my default browser.

This is really an error for Free YouTube Downloader to correct, but many FireFox users must have solved this already. Any advice?

Thank you!

The recommended methods, changing to this in the registry :

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\Certificates] "ImportEnterpriseRoots"=dword:00000000

Reverts back to 00000001

Put this policies.json and did nothing: {

 "policies": {
   "Certificates": {
     "ImportEnterpriseRoots": false
   }
 }

} What am I missing or what's changed?

My specific need at the moment is to add another search engine option in about:preferences#search

Thanks.

When I want to access a site, I am told JavaScript needs to be enabled for access. In checking I am told JavaScript is already enabled. To check it, I should about:config in Firefox mobile and toggle JavaScript to true if it is shown as disabled. However, when I do that I am blocked for safety reasons. I want to know what's happening here with JavaScript and Firefox mobile.
