Diễn đàn hỗ trợ Firefox

I'm having a novel problem today for the first time. Firefox is apparently using a p2p protocol, and I have no idea why. My VPN is detecting this whenever I open Firefox. I disabled all extensions, tried opening Firefox's safe mode, and it doesn't matter what tab is open. Brave browser doesn't give me this problem. My VPN's servers do not allow P2P use, so this is a big deal. Why would Firefox be setting off the p2p alarm, and how can I fix this? I'm using the newest Firefox version on windows 10.

I recently noticed that the Windows 7 feature of searching the internet directly from the start menu (via policy and explained here does not work any longer. The search string is not pasted into the seach box. The feature still works with Chrome 83, so it is safe to assume it's not an OS issue.

I just downloaded Firefox as a first install on a new installation of windows. When I open twitch there is no volume control bar, the ability to put the stream into full screen or theater mode, or the ability to change the quality of the stream. Is there something I need to turn on to get this working?

Firefox has stopped display embedded images in my E-Bay listings. See the attached screen shots for the HTML code and results. I have tried all of the solutions posted here with no good results. This seems to have started in the pas few releases.

So I've been using firefox for a while now, and I really like it, but in the past few months it has suddenly decided that my browser is out of date (not the case, I'm running the latest update) and unsupported, even though it says firefox is supported. This happens on a lot of different sites. I tried resetting my useragent and clearing my cache and cookies, but nothing seems to have happened. I still get the bug. I submitted to webcompat too.

Please help, its super irritating to deal with, and I don't want to have to switch browser.

I have been using firefox for years and am very happy with it. I have a Dell optiplex 7010 desktop. I am running Ubuntu 18.04.4 LTS. I do not have a firewall turned on. Apparently, my desktop browser was updated to Firefox 78.0.1 (64-bit) on 7-1-2020. Since that time, I have been unable to access any websites from Firefox including mozilla.org. I am connected through WiFi. After downloading the Opera browser I have been able to access any website with no problems. I read community troubleshooting on this issue and tried various fixes including turning off IPv6. I read the community article about turning off my personal firewall. I was unaware of using any firewall so I installed Gufw Firewall 18.04.0. Running this program shows my firewall status is "OFF". I checked my AT&T modem and could not find any firewall settings that specifically mentioned Firefox. I would like to continue using Firefox since I use it on my phone and laptop also use it.

My laptop is a Dell Vostro 1520 running Ubuntu 18.04.2 LTS 64 bit. It also accesses the internet through the same WiFi. It currently has no problems loading web sites with Firefox version 78.0.1

Please help.

I live in the mountains of North Wales so am at the end of a lot of copper or (even) aluminium wires. I rotate ISPs regularly and have been at this shit since the WWW was invented and have even bought a Cisco router to host our own web site in the 1990s. I KNOW that the ISPs manage my connection speeds, router management software WILL be more capable than the Cisco router we managed ourselves!! I notice a similar profile of getting the speeds that are advertised at the start of a contract and then to throttle it as they add more customers to the same kit that they lease from OpenReach; increased latency! I also get OpenReach business notifications and know that the ISPs pay OpenReach for not only bandwidth that they use but also the electricity that powers them, OpenReach also charge for shit loads more but lets stick to the simples! ALL the ISPs deny ANY management function which is disengenuous to say the least!! There is a worrying trend in businesses to not only have no usable phone numbers (I had about eight BT numbers when we had the Cisco Router but NONE work anymore) due to the telephony shit that infests what laughly passes for customer service these days. {Thinks: Is there an undisclosed word limit to this field!?!?? I daren't hit return to go to a new para 'cause it might send like the excreble messaging systems which pass for comms in these benighted days!! My point for the designers of Firefox is: when I try to do "Speed test I can count up to FIVE seconds before a Ping is registered which is never more than a 100ms so that's bollocks! Then it doesn't matter how many tabs I have open (often shit loads) the speeds that I get are independant and even when I'm "listening" to radio articles that doesn't effect the results either! A GENUINE speed test should be built into Firefox don't ya think??

I have the latest FF on my Windows desktop with no new add-ons. The past month or so when I load pages, usually ones that have a lot of ads, all the ads or other extras on the page start flickering - the icons for stop loading and reload alternate back and forth fast. I can stop the flickering by clicking on one of those icons but why does it do that? It makes the whole page distracting to read. I sometimes have to do that for page after page.

On some sites and a NextCloud installation, I suddenly cannot click on some links that report following error in the console: Uncaught Error: Permission denied to access property "apply"

   jQuery 7
   clear searchprovider.js:292
   attach merged-index.js:11661
   jQuery 8
   _setCurrentDir merged-index.js:5820
   changeDirectory merged-index.js:5752
   actionHandler merged-index.js:3432
   action merged-index.js:2894
   _onClickFile merged-index.js:4757
   Underscore 3
   jQuery 2
       dispatch
       handle

I've checked and disabled add-ons to see if these were blocking somehow, but no result. It worked fine before, so my suspicion is something changed in FF78? Thanks!

A group of experienced hackers have made my devices their target. They continue to remove any security I try to place on my computer, i.e., downloading developer apps which allow them to administer the computer and devices.

They have maliciously targeted my business and sabotaged a lot of my apps so that they will not work. Going to the "Authorities" is a waste of time. so I will not discuss this.

I need help in tracing the street trash thugs who continue to access my computer, place malicious malware and worms on my computer so that it will not function at his required level, and replacing bonafide adds with fake apps so that they can control and conduct surveillance on all of my Apple Devices.

I have reported this problem to Apple and they are worthless. Not enough training, and the service is inferior.

I need upper level technical support to identify how they are manipulating my browsers so that they provide absolutely no security.

Malwarebytes is manipulated, Avast as well, and they have downloaded an app that allow them to share my screen and collect all of my passwords as they are individually entered.

Hi today I opened my linux installation and Firefox is only getting a window with the text:

             <toolbarbutton id="UITourTooltipClose" class="close-icon"
</pre>
I tried to run from the console with the  --MOZ_LOG_FILE flag and the generated file has absolutely no text in it.
Some information about my system:
kernel: Linux localhost.localdomain 5.7.7-1-default #1 SMP Wed Jul 1 19:03:27 UTC 2020 (cba119b) x86_64 x86_64 x86_64 GNU/Linux

Lately ( maybe a month ) my screen started to act strangely when in the message center of Aliexpress . The power led in front of my lg 27ud58 lit up and the screen blinked in repetition . The same thing occured when in other site with an interactive design . After making sure i was running with the latest drivers, i tested those site with chome and everything was fine . This problem imitate a faulty cable but why not in chrome ? I'm using Firefox 78.0.2 for Win7 .

and I have already changed the starting page and indicated that for an extra page I want an empty page, but it keeps giving that page. This is since the last uodate. I don't want that because it is very enervating !
