Diễn đàn hỗ trợ Firefox

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!

Greetings, Mozilla Community

I'm contacting you to ask for help with a problem I'm having with Mozilla Firefox when attempting to visit the website https://proroofingcontractorgreenville.com/. The website won't load, and I'm not sure if that's because of a technical glitch, incompatibility with certain browsers, or anything the browser may be obstructing.

Has anyone else had this problem or has advice on how to fix it? I've tried removing extensions and cleaning the cache on my browser, but the issue still exists.

Any advice or tips on how to navigate the website more easily would be much valued. I'm grateful for your support in advance.

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.

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.

How do I get rid of this on my Firefox browser it keeps coming up all the time??? https://www.offidocs.com/media/system/app/view_edit_pdfeditor_nav.php?myServerhost=tut&urlpathx=/community/pdfeditor/editios-ext.php&service=--&username=rkl8d4hjzu&filepath=68747470733a2f2f7470622e70617274792f7c7c7c68747470733a2f2f796f7572616463686f696365732e636f6d2f636f6e74726f6c

I used Firefox Developer Edition and yesterday saw that a new extension released for using Chrome web api to search and duckduckgo as one and had to test it "DuckDuck Chrome"... I have since had keneral level drivers registered, IP addres ls directly connecting, every one of my files scanned and index and still I'm getting logs for connections from the same IP's that were using kernal calls to bypass me seeing whats going on... at one point they did a lernal call and changed the requested package power.

There were enough things ran from 5am pst today till 4pm pst today I have exporting the log file for multiple hours and it only has a tray icon telling me it's still creating it as the context was to large to be seen or queried in the Event Viewer itself (error 1734).

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?

Hi, I'm using Firefox 125.0.3 64-bit with Linux mint and some of the tiles on the homepage have disappeared I have selected 4 rows in settings but only 2 and a half rows show, I can remove all rows and select 4 rows again but only 2 and a half rows will show all the edit, pin etc, options are there and work and I can rearrange the tiles but if I dismiss a tile it disappears completely, any help much appreciated. please see added image.

I can add the short cuts I want but if I go someplace new Firefox will add it to my shortcuts without permission. This seems to be a new problem, and I don't like it! Then if I dismiss or delete from history its still not removed! Very annoying and may cause me to ditch Firefox for good!

I using kubuntu (ubuntu with kde) 22.04 and firefox will not recognize my security key. There is a really good thread on this here. It is now closed.

One of the solutions is to install firefox from the mozilla server. On other forums, this is referred to removing snap and installing the debs. I haven't tried this.

Reading through the thread however, it seems like the snap version should work. The manufacurers id and product code for my Thetis FIDO2 usb key are present in the etc/udev/rules.d/70-snap.firefox.rules

This answer says to disable apparmor. I tried that, but it didn't work.

I have quoted this answer below.

This isn't actually a firefox problem. KDE Neon uses the firefox package from the Mozilla Team PPA and there's nothing wrong with that package. The problem is that Neon enables app armor on firefox which breaks access to password managers and security keys. sudo aa-disable usr.bin.firefox works around the problem by disabling app armor for firefox. aa-complain was not sufficient in this case.

Is there anything else I can try?
