Diễn đàn hỗ trợ Firefox

Ever since installed Ubuntu 18.04.5 LTS (& latter upgraded to Ubuntu 20.04.2 LTS), I am unable to watch YT live videos! Below are the screenshots of the issue & a test page report.

Moin, I activated the HTTPS-only mode as I used the "https everywhere" plugin so far.

But, in a very special network segment for radio amateurs, the 44-network (ampr.org) encryption is not allowed. So is there a way to configure the HTTPS-only mode in a way to say ".... but not for 44.0.0.0/8?

i prefer one configuration than constantly clicking the "continue to http site" button for the next few years.

Thanks in advanced

I have three FF profiles on my Linux Mint 19.3 system (work, not-work and one for e-tail). Somehow the problem only appeared after I added that last one. All profiles have the same syntax; I checked the files. Neither one is set to be the dominant one. Typically, I don't use more than one at a time.

I also use Claws mail. Whenever I get any mail with a link I want to check out, I just used to click on that link and it opened in a new tab in the FF browser profile that was currently open. Similarly, whenever I wanted to see the HTML version of a mail, I right-clicked on the html-icon and chose open. Again, it picked the open browser.

Now, though, whenever I pick either one of those options above, I get the "Choose User Profile" box. If I pick the profile that is currently open, I get an error telling me that it's already running.

Since I mostly read email when I use the no-work FF profile, I tried to add "firefox -P NotWork -no-remote --class NotWorkProfile" but that also resulted in the choose user profile box to open.

My current work-around is to copy the link and open it in a new tab, or pull the whole mail into the tab to see the HTML version. Quite annoying.

Is there any way to get it to ignore all other profiles but the currently open one? Thank you for anyone who has an idea. Let me know if there's anything else I may add to explain the situation.

[My apologies if this isn't the right forum; I'm also attempting to ask this question in the Linux Mint and Claws forums, if those exist.]

I got an email with a .docx attachment, and when clicked attachment I can view in FF.

Downloaded, and clicking file and open in FF ends in endless loop asking to open, if FF selected. Seems like mime type not being detected and processed from FF directly but does from webmail.

Same action with a PDF, image files works great.

My ISP is Plusnet. When I try to access their website using Firefox browser I get the following error:

=====

Secure Connection Failed

An error occurred during a connection to webmail.plus.net. Cannot communicate securely with peer: no common encryption algorithm(s).

Error code: SSL_ERROR_NO_CYPHER_OVERLAP

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the web site owners to inform them of this problem.

I have reported the problem to Plusnet but they say 'not our problem'. Their reason being that the problem does not occur using Google Chrome.

Can you help please?

Using FF 88.0.1 in both Linux Mint and Windows 10 and without syncing add-ons, The "New Tab Override" looses my granted permission and opens a new tab on it's own Options/Preferences page, where it shows that permission is granted.

The simple solution I found that clearing the Startup cache restores functionality.

Already reported this on the add-on's Github site, which directed me back here.

Hi all,

since I set up my blog I am sometimes & very infrequently experiencing the problem that either the style sheets are not supported (see attachment), or I am getting an error message to the effect that the address of my blog can't be reached. I already posted in the WordPress forum, and a user took a look at my blog, but couldn't replicate the error. So I came to the conclusion that this is maybe an issue with Firefox. My question: Can anybody replicate this error, and may--if possible--be post a solution here?

TIA,

Claus

The firefox installation on my desktop is not able to render anything.

Even the about:preferences window is not able to show anything both under my account and a new account I made. I even attempted to update to a new version of my distro (Pop OS) in an attempt to fix it.

My Firefox account is able to do a sync (shows up in the dropdown) so it does not have to do with proxies. Chromium also works fine.

I would rather not have to use Chromium so any help will be appreciated. I have tried running firefox in safe mode and doing a "Refresh".

Hi forum The email provider for my preferred secondary email address uses greylisting. It works, very well. The confirming email from firefox is sent from a random amazon address, which gets greylisted as intended. There's a 5 minute limit for entering the confirmation code, but greylisting slows delivery of the email to around 15 minutes, waiting for the amazon sending server to try multiple times. Is there another way to update the secondary email address ?

There are only a few things that I need on right click. Open in New Tab, save image as, copy link, copy link location. Only rarely do I use the developer functions, so that over time I am accustomed to accessing the Developer Tools from the Tools tab on the main menu. The fact that many of these tools that I do not use are now on the right-click menu are causing me to make errors. I subscribe to an online newspaper that is the first item I read in the day. I go through the front page of the newspaper, I right click on articles I want to read in a new tab. I am so used to doing this efficiently from older versions of Firefox in which the right-click menu always opened where I right-clicked and therefore at the "open link in new tab" selection. Now, what happen is that I react by instinct and find myself clicking the middle of the menu and not the top. This results in errors that waste my time and cost me time and frustration.

Having read a few other problems that other people have had with updates of Firefox, I have to add my voice here. I realize that there are legitimate reasons to change some things - but these things are technical and deal with internet security - not style. It seems to me that constantly moving things around (like menu bars and the like) interrupts a user's accustomed work flows and therefore not a benefit.

It seems to me that there are two possible solutions: One is to make every aspect of user preferences editable by the user. For me, that means the main menu bar is on the top, followed by the tabs, and the right-click or context menus are editable by the user. The other solution is to create two Firefox browsers - one for the traditionalist (I'm 82) and a new browser called "Firefox Superuser".

For now, I'd just appreciate it if someone could tell me how I can get the stuff I don't use off the right-click menu.

I apologize for my grumpiness, I realize you're all volunteers. But, first thing in the morning, having to try to remember that the right click menu might not be opening with "open link in new tab" right next to my cursor is more than I can manage. I automatically click and at least 80% of the time, I'm clicking the wrong thing.

I upgraded SuSE leap 15.1 to 15.2 two days ago and still can't play videos or live streams on most of websites. Works only on youtube and rumble. On twich, netflix,odysee and several others is no go. With other web browsers is just a same, I tried Cromium and Opera I have and love Firefox 78.10.0, ffmpeg is installed , Leap is updated via Yast ... what is that I'm forgetting?

Thanks,

Can someone help me customize the appearance of the active tab? I was able to remove the borders and separators, however I'm now left with a thin white line at the bottom of the active tab and I don't know how to get rid of it. I have tried changing the border and padding, but nothing really helped:

Anyone with an idea? Any help would be appreciated.

Hey there,

I have the following issue with Firefox, is this maybe something I should report to the Ubuntu support or directly to Bugzilla?

Steps to reproduce: ---

1. Open Firefox
2. Go to a page that contains an embedded video that is not playing automatically, e.g. https://www.rottentomatoes.com/m/sound_of_metal
3. Do not play the video

Environment --- User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:83.0) Gecko/20100101 Firefox/83.0 Firefox version: 83.0 (64-bit) pulseaudio version: 13.99.2 OS: Ubuntu 20.10 64-bit Gnome version: 3.38.1 Windowing system: Wayland CPU: Intel® Core™ i7-8565U CPU @ 1.80GHz × 8 RAM: 15,5 GiB GPU: Mesa Intel® UHD Graphics 620 (WHL GT2)

Actual results --- pulseaudio process is spawned and rapidly becomes the most CPU consuming process on my machine (especially after a few seconds, when the Web Content ones start to cool down). Even though no sound is actually played! When switching to another tab with no embedded video, pulseaudio keeps overloading the CPU. This only stops after closing Firefox.

Expected results --- I'm not sure this is what should be expected, but I'll give it a shot:

• pulseaudio process should only be spawned when actually playing a media that requires audio
• pulseaudio should not be the #1 CPU consuming process
• pulseaudio process should at the very least not massively use CPU when no sound is playing

Hi,

I'm using Firefox over various devices and systems.

For instance: - Firefox binary downloaded from Mozilla website and executed over Debian Testing - Firefox from Arch Linux official repositories in Arch systems

My doubt is: could this cause any problem with the Sync function? Or Sync has the flexibility to allow syncing between a wide specter of Firefox installations

For instance: Could I add Fennec from F-Droid to my LineageOS smartphone or Firefox-ESR from Debian repositories to my desktop machine, log in with my account in all of them and synchronize all the sessions without problems?

Thanks a lot in advance!, and let me know if I should add any technical information.

Kind regards!

Say you are reading [this comment](https://github.com/philc/vimium/issues/226#issuecomment-847959671) in the thread and you click the first link, titled "philc". That now brings you up to philc's comment, but how do I get back down to my original spot in order to continue reading?

This is only a problem when navigating within a page, as if the link is opened in a new page, closing the new page returns you to your original spot in the original page.

Dear Mozilla Community,

I would like to suggest you to make built in adblocker in Firefox. For example Opera have this feature so we don't need install any extension. People from Mozilla read subjects in support.mozilla.org? If not where I can send my suggestion?

P.S. I wanted to install Adblock Plus extension but I am afraid about safety so better option is to make built in adblocker to protect from malware. I think that this can be direction in good way.

Yours faithfully, Piotr

Hi, I'm running Firefox on Ubuntu 20.04.2 LTS Gnome Version 336.38. For at least one month now Firefox has stopped working. When I start Firefox normaly (or in the tor-browser bundle) the Firefox-Window opens but no page is loaded. No matter what page I navigate to, nothing happens. I can't even open the firefox settings. I updadet from the normal version to 89.0 but still nothing working. Anyone got any ideas?

firefox 88.0.1-1 on linux Since recently firefox started to open random udp ports that's what i see in netstat udp 0 0 0.0.0.0:36531 0.0.0.0:* 16227/firefox udp 0 0 0.0.0.0:43783 0.0.0.0:* 16227/firefox It only happens on some sites likes youtube and discord is that related to http3 in some way? there is nothing in about:networking

I am just not sure if this is anything to be concerned with, i did a bunch of searches for firefox open ports, but couldn't find an answer
