Diễn đàn hỗ trợ Firefox

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?

in google and in other browsers when you have multiple tabs in a container you have an option to minify all tabs in the container. is there a similar feature for firefox,

thank you!

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?

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!

When photos, videos, or websites are linked on a FB comment, it used to display a thumbnail preview below the comment. Now it just shows the link. On mobile, the preview appears. So I'm thinking a setting got changed on the desktop version.

Does anyone know what the issue is and how to correct?

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!

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.

I had downloaded a couple of pdfs from google drive via private browsing which were stored in my 'Downloads' folder. But as soon as I closed the window the pdfs were deleted. I had also downloaded a zip file which wasn't deleted.

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,

I recently facing an issue that the Firefox browser randomly maxed out my RAM and went unresponsive. Like the screenshot below, I am only trying to open Facebook and Instagram, 2 tabs.

I have tried to open about:memory and about:processes to monitor but it just went unresponsive and both the monitoring just hanged.

Have no idea why the Firefox process taking up so much RAM. Need help.

I was able to open reddit.com without any problems earlier, but recentrly I'm not able to load it up anymore. The loading screen is eternal and it doesnt show any kind of error (unless it tries to connect for too long like a couple of minutes, then the error does shows up). The site still sends me notificarions through the browser though. Any other site loads up without a problem. I tried to use methods mentioned in the help article (turned off proxy, turned on network.dns.disableIPv6, deleted cookies and cache). In other browsers (Edge, for example) reddit.com loads just fine. Please help me if you can.

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

you dont need a screenshot. its reral simple i am tired of nothing working right. i have added multiple wallets on my phantom app but it doesnt show up on my phantom wallet on my laptop. i have been hitting check for updates for 2 hours. why wont it update. and if i have to put in a 24 word secret phrase evertime i want to update my extension. then good bye firefox. then why have a check fofr updates button.

I've always had my firefox checkmark the "Always ask you where to save files" box. I started to download a file from Envato elements, and firefox asked me where I wanted to put it, so I pointed it to a dropbox folder on my finder level (I'm on a Mac computer). Some pop up showed up that said it didnt like the directory so I hit ok. Then I tried to download again to another location but now firefox won't ask me where i want to download the file to. And instead it just populates a file in the downloads folder called "7gp69ST8.mp4.part" or something similar. If I uncheck "Always ask you where to save files", the whole file downloads just fine to the downloads folder but I dont want that setting, I want the check mark ON so that it asks me each time where to save the file to. But its not asking me any more. So I hit quit on firefox and came back in and the issue persisted. I cleared the cookies and the issue persisted. Please help me fix this.

Hi Lots of my files on Mac have converted to Firefox (which I don't use) and will not open either in Mac, Adobe or Firefox. They are showing in my icloud drive but I cannot open them. And I REALLY need them as they are the source files for a website. I have no idea why this has happened, but would love some advice on how to fix it. I don't ever intend to use Firefox so not quite sure how it happened. Many thanks

A few days ago I started having an issue where Youtube videos 1440p and up would frequently skip ahead, stutter or freeze and play audio only. They also stopped loading as quickly as they had before. This issue only happens in Firefox as when I watch Youtube on Chrome everything is fine. I've tried disabling extensions to no effect. Is this a known issue or does anyone have suggestions?
