Firefox Community Forum

Using the Firefox browser, I tried to copy an image and wasn't able to do so. Then I copied an image using another browser and wasn't able to paste it into a Facebook post on Firefox. Please tell me how to fix this. I can't copy/paste text either. Could the problem be my Mozilla VPN?

Hello there.

Since last update i'm unable to browse websites like youtube, social media and all other websites with video content. Video often fails to load,the wholewebsite is not loading, freezes while played or while exiting full screen mode. All of these freezes the browser - the site cannot be refreshed, links does not work. The only way is to close the tab with the freezed page or kill the Firefox process in windows Task Manager. Refreshing, re-installing, deleting or using different profile don't work. Same with add-ons. Seems like the issue lies within the browser and it started to appear since last update.

Hi, for the past month or so I'm not able to reply to emails using Apple Mail on Fire Fox browser. The arrow gets cut off in the upper right hand corner. Also I'm not able to move emails into their appropriate folders by selecting the folder icon in the top middle of the screen.

All my attempts to pay online with 2 out of my 3 cards have failed in the last 2 weeks. The Mastercard says it has connected to my bank and I'll get an SMS - but the SMS never arrives, and when I phoned my bank, they said they had no authorisation attempts reach them at all! The Visa card simply says it failed at the first step, without saying why or serving up the usual security dialogue. (The other Visa card just works).

I suspect the Autofill may be the problem here. I've recently had other scenarios where FF filled in a field for me, but the Javascript behind the website refused to accept it, eg saying it wasn't a valid phone no when it clearly was. The only way to get round this seems to be to type in the complete value yourself, which rather defeats the object. It could be something else, but it's clearly dependent on which software's running behind the card, as the third card succeeds.

All the tabs, in both my profiles are constantly crashing. I cannot keep at a task for more than a few minutes without needing to restart the tab. Is this a setting problem? I've cleared the cache, and reset Firefox, to no avail. Thank you for any relevant advice and/or assistance.

This past Friday morning, May 29, I tried to access www.healingwell.com which I have always been able to do. But this time Firefox gave me a red screen with message: "Firefox blocked this page because it might try to trick you into installing programs that harm your browsing experience, for example, by changing your homepage or showing extra ads on sites you visit." And same message again over the weekend. But yesterday, Monday June 1, I was able to access that website, and all seemed normal. Why did Firefox give me that message on Friday, but not yesterday or today?

I edit a newsletter substack and sometimes I have links embedded in it. Mozilla denies me access to those links when I check the newsletter. Do I have to cancell Mozilla protection to have full access to the links in my newsletter from substack?

Hello! Is it possible to recover older open tabs from a broken device that had sync activated? For a while they appeared in the hamburger menu in the top right, but now they suddenly disappeared, and under the "connected devices" I cannot click the device or anything. It went broken 2-3 months ago. Best wishes!

성인사이트가 크롬과 엣지에서는 정상적으로 열리는데 파이어폭스에선 보안 연결 실패라고 뜹니다. 원래 파이어폭스에선 성인사이트를 차단하고 있는 건가요? 아니면 차단을 해제할 수 있는 방법이 있는 건지요 Adult sites open normally on Chrome and Edge, but on Firefox it says security connection failure. Is Firefox originally blocking adult sites? Or is there a way to unblock it

When I click on a link in outlook recently, I have been getting an seperate firefox pop up but it has none of my passwords. How do i set up to have all the info as the regular firefox browser I use.

Hi everyone,

I'm having trouble accessing my local network devices (a 3D printer and Raspberry Pi) using short hostnames like "http://impressora3d" or "http://impressora3d/". Firefox keeps blocking the connection with the "Looks like there’s a problem with this site" error page.

I've captured a network log using 'about:networking' and I can see that: 1. DNS resolution works perfectly and points to my local IP:

  "CompleteLookup: impressora3d has 192.168.1.10"

2. Firefox is upgrading the request to HTTPS (port 443) automatically:

  "nsSocketTransport::ResolveHost [...] impressora3d:443" -> "pushing io layer [0:ssl]"

3. The device rejects it because it only listens on HTTP (port 80):

  "Bad Socket 804b000d" (NS_ERROR_CONNECTION_REFUSED)

What I have already tried: - Disabled "HTTPS-Only Mode" entirely in settings. - Checked "Secure DNS" (DoH) settings (set to Increased Protection and added exceptions). - Cleared history and used "Forget about this site" on the hostname. - Typed "http://" explicitly.

Firefox still refuses to connect via plain HTTP (port 80). Is there any hidden 'about:config' preference or HSTS cache forcing this behavior for local unformatted domains?

Thank you!
