Firefox 技術支援討論區

There seems to be something specific to the Phlearn site and Firefox which prevents videos from auto advancing. They either recommence the just completed video or revert to an earlier one.

Hi there!

I'm trying to troubleshoot why firefox isn't connecting to my DNS over HTTPS instance running adguard home. Every other device (including another laptop) is able to set the DNS over HTTPS and connect successfully - but my desktop PC instance gets NS_ERROR_CONNECTION_REFUSED. Despite multiple reboots, ipconfig /flushdns, release/renew, etc...

Even my android phone is able to connect to it using the "private dns" feature (uses port 853 instead of 443).

I've been able to verify https access to the DNS server and it's querying successfully. It's just this one instance it won't connect.

Windows 10. Weird glitch.

If I use Wondershare UniConverter's downloader function to download a video, as soon as the download starts, all Firefox open windows close. This is a recent thing, the last couple of weeks or so. I have reinstalled Firefox and UniConverter. The first time I tried it after reinstalling UniConverter, all was well. But the same issue has shown up again. I have tried rebooting my PC to no effect.

Any bright ideas welcome!

I have scoured the web and read/tried everything. I cannot remove the time and date stamp from my documents. No matter what program/app they are printed from it shows up ruining my printing. I've tried unchecking the header/footer box. There's nothing in my brother printer set up regarding the date/time stamp. It has to be firefox. How do I fix this? I'm not a computer guru so I need details. I'm at my whits end! Thanks!

Steps for reproduce:

• Turn ON PC
• Launch Audacious player
• Launch Firefox
• Visit to drupal.org

And I have sound glitches like on radio tuning. From all software, that have sounds: players, browser, messengers. Glitches disappear after restart. I find only 2 sites, that make it: drupal.org and my local bank. With Chrome - no problems.

Without Audacious glitches can be to, but not in 100% of cases.

Well, since I changed to a new computer with Win 11, videos on Facebook don't play right. They are videos that are posted by various people and real entities. They are not smooth. They start to play and immediately pause then jump forward then pause and jump forward. If I copy the link and go to Chrome, paste the link and play the videos, they are normal Never did that on my old computer. Any ideas why the videos don't play normal?

hello when i write many cell code in google colab and then run all of them when output there and i want to scroll up from last cell code to go to top of page,i have lagging for scroll up in that and this problem just in firefox and in chrome is'nt problem thanks

I've noticed that when logging into various websites, a random email address not known to me appears in autofill among my usual email addresses. This unfamiliar address is under the @shanreto.com domain and shows up across different websites. My Firefox account is synced between my PC and mobile phone. Both devices are password-protected and under my control at all times, and I have only installed uBlock Origin as an extension.

Could there be any explanation other than the possibility of someone accessing one of my devices through malicious software or similar means?

bold textExperienced Firefox browser session freezes a month or two ago. It seemed that some March/April '24 fixes/patches stabilized the app. They are occurring again with increased frequency. What should I do to avoid this problem or switching to another browser? Thx

When I watch a video not in the full screen mod, the colors are as dark as they're supposed to be (pic 1), but when I enter the full screen mod, the video gets pale/brigher (pic2, compare the dark zones). it's fully connected with hardware acceleration. When it's on videos get pale and when it's off they don't. But I can't turn it off because I also need it for an addon I use as it won't work without it. Someone on the forum here said that turning on layers.force-active might help with a bug of hardware acceleration. I turned it on and it helped - acceleration was on and videos didn't get pale, but then everything got back and now this setting doesn't work anymore. I also opened trouble shooting mode and videos didn't get pale with it even with acceleration on, but I don't know why, becaues when I closed it I deleted all the extensions, turned on acceleration and videos got pale again. And, this problem is only in this browser. This problem really keeps my up at night and I'm so tired of it

Long ago I used to never have to hit F5 to see today's version of a page instead of the cached version, and I do NOT want to clear cache or cookies or history on exit, no, that's not the setting I'm looking for, thanks.

Why you create Mozilla account with sync, if I can't use profile which I saved on my old PC. I change my PC and now I can't use my open tabs as needed, I need to open each tab one by one. Why ??? Why I can't use saved profile on my new PC ??????

When I pull up my settings, it states that my browser is being monitored by my organization. The problem is that my laptop is my private laptop and not connected to any organization, at least, not with my knowledge. When I click on the link associated with the message, it lists two policy names. One policy value is locked with the word true after it. The other policy value is unlocked with the word false after it. What do I do?

In Chrome, I can hit CTRL+SHIFT+I to open developer tools, add the Media tab, and go to the Media tab, and I can see the codec and what decoder is being used.

How do I do the same thing in Firefox?

For some reason when I opened Firefox this morning, my Firefox home page did not have any of my shortcuts. They all disappeared. Please have a look at the image attached to see what I mean.

I spent almost the entire day searching up the issue on the Internet and trying different things but they all did not work.

Look forward to your reply.
