Diễn đàn hỗ trợ Firefox

Hello, When I view some pages with inline video graphics, I see a garbled video frame. I have attached a screen grab from part of one screen. I have no issues with YouTube or other videos. It's just the graphics of some webpages such as looking at an Apple product on their site. I have not had this issue using Chrome under the same conditions. It's like I have a corrupted Codec or something. Does anyone have any suggestions? Thanks.

I recently added the "Display Autoplay" extension. I can't seem to figure out how to get the icon to show in the tool bar. See Attached acreen shot. That's assuming that this extension icon can be added to the tool bar. I look forward to anyone's comments. Thanks

I have encountered PR_CONNECT_RESET_ERROR for the last few days. All websites cannot be accessed. I tried to uninstall/reinstall Firefox several time and nothing works. My system is Windows 11 Home, Version 22H2, Installed on ‎2/‎7/‎2023, OS build 22621.4037. Kaspersky Anti Virus is 21.3.10.319(m).

When trying to use one particular website on Firefox, I get a message that I am blocked because of an ad blocker but I have not turned on any ad blocker in Firefox. How do I find out if an ad blocker is enabled on my Firefox and, if so, how do I turn it off? I have ensured that the ad blocker option in settings is unchecked and even added this web site to permissions but to no avail. Can someone help? Here is the message I get but none of the steps in this message I am told to take show up on my screen:

Adblock Plus Instructions

   Click the AdBlock Plus icon in the extension bar.
   Beneath “Block ads on”, click the large blue toggle next to “This website”.
   Click refresh.

Were these instructions helpful?

Version 129 is not printing headers and footers, despite manually checking the "print headers and footers" box in the print dialog (and despite making Page Setup visible via about:config). This persists in the preview, when printing to PDFs, and when printing to physical printers. This is new behavior to me since some time in the 128 series (the last time I tried to print a webpage showing the URL and date/time).

I have manually reset all print_h... and print_f... entries to default, but that didn't help either.

I am having trouble pinning any Extensions to my toolbar. When i click on the Extensions icon (puzzle piece), the Extensions menu immediately pops up. My extension (Bitwarden) is set to "Enabled". When I click on the three horizontal dots, however, the only options are 1) Remove, 2) Report, or 3) Manage. There's no option given to pin the extension.

Because of that, the extension basically never opens, and I am unable to use it. Does anyone have any suggestions for me? Thanks in advance.

I am running Firefox 129.0.2 (64-bit) in Windows 11 on a Surface tablet. FWIW, the extension is running fine in Chrome.

I want Protonmail as my default mail for Firefox. Windows 11 allows me to install Protonmail as an application. I cannot find or use that application in order to use my Protonmail email as my 'mailto' option in Firefox. Why does Firefox not allow this? Why can't Firefox find and suggest the Windows 11 Protonmail app in its list of suggestions under 'mailto' options?

I like to clear the cache on a regular basis but then Facebook does not recognize my laptop and I have trouble logging back on. Is it possible to clear the cache for all but a select website? Thanks

I downloaded a large filed in my Firefox Browser and it took me 2 days to download the file but when it's almost done, it suddenly failed download. Can you help me resume the download? I think it stopped around 60 gig.

For some reason I looked into whether my Firefoxes are ever using HTTP/3 - turns out they aren't. I looked up how to get any kind of information on this, and saved networking logs. They indicate that the moment Firefox tries to send the first UDP packet for the HTTP/3 connection, it gets "ErrorAccordingToNSPR [in=-5987 out=80004005]", the connection fails, and the server is added to an exclusion list so that no further (futile) attempts at using HTTP/3 will be made (which makes reattempting a HTTP/3 connection by hand that much harder). The initial platform was Windows 11, with Firefox 98.0.2, but afterwards I reproduced the issue on another PC running Windows 10, and with a nightly version on Windows 11, which I also used to save some logs which I can publish, as they don't reveal the sites I visit (though I can always provide the logs from my everyday instance of Firefox, should you find the information insufficient).

I also confirmed that HTTP/3 works with Chromium on the very same system and network, and also with Firefox on another machine running Linux.

For the past several months, I've had increasingly worse graphical errors on Google Drive. At first it was only in a few documents, and now it's in every single document. These errors only occur on Firefox, no other browser. Text that I type is constantly blurry, oddly-sized, or oddly-spaced, with some letters touching while others have large gaps between them. I've also had some other small issues, like the document thinking that I'm two people and asking me if I want to see "the changes made my collaborators" when I'm the one currently typing (the documents aren't shared with anyone else, and there are never any changes beyond the ones I make), or showing my cursor highlighted with my name as if I were someone else watching myself type. It's made it more difficult for me to focus on work and I don't know what to do about it.

I've tried the following methods (most of them multiple times over the past months) to solve it, none of which worked: - Running the windows in safe mode - Uninstalling all add-ons and themes, clearing cookies and cache, and then restarting my computer - Uninstalling Firefox entirely, restarting my computer, then reinstalling it - Refreshing Firefox - Looking through pages like Firefox Task Manager and such (although the information there didn't really mean much to me, nothing looked out of the ordinary)

Does anyone have any ideas about what I can do about this? I was ignoring it for a while since it's still legible, but it's become really annoying, especially when it makes some words hard to read. Thanks in advance for the consideration. Here's a screenshot of a document with the weirdly-spaced, blurry text:

I had a Firefox account on my phone. I got hacked. So I uninstalled the Firefox app. I got the upgrade for Lookout and added that to my phone. I opened a new Firefox browser on my PC because I was tired of Google and I don't like Bing. I think you are still using my phone account. dawniegirl1973. lt has never been a primary or secondary email for phone or Pc. But you caught the last hacker! I would like an upgrade with Firefox on both PC and phone if I wouldn't have to pay for both devices. Would that cover both PC and phone? They are not linked, but they do share 2 emails and passwords. I also would like VPN, if that would secure my wifi. But I need a network that I can use for all my internet needs. I don't know what all VPN does. Please help me out. I don't know what to do anymore. It's all gotten so confusing. I'm tired of being hacked. Please advice. I trust, you, Firefox and I want you on both devices can we do this?

New computer, running Windows 11, McAfee LiveSafe came with for 30 day trial. I use Firefox, have since 1997. Just added Mozilla VPN. Old computer ran Xubuntu. Windows 11 needs antivirus because it's Windows. So. How compatible are McAfee LiveSafe and Firefox with Mozilla VPN? What suggestion, if any, does Mozilla have for an antivirus program that will work well for Windows 11 but not mess with Firefox and Mozilla VPN? Thank you.

I travel for work and often stay at IHG properties (Holiday Inn, etc.). I have Firefox as my default browser; version 99.0. I cannot login to their wifi using Firefox; I have to copy the address and paste it into Google Chrome and after confirming my information I am able to browse normally until the next day; It must reset at some point.

This is the web address for the network login: https://www.msftconnecttest.com/redirect

I read this article about Captive portal detection: https://support.mozilla.org/en-US/questions/1314194 I change the setting per the article hoping it would take care of my concern but it did not.

Thank you!
