Firefox-Hilfeforum

I have a problem where if I install the packages needed to get hardware video decoding working in firefox it completely breaks YouTube playback. I can't find any info on the internet about the problem and I am having a lot of trouble with it. YouTube playback with libva-mesa-driver and libva-vdpau-driver will start stop restart start playing audio then crash with a this error every single time. I am at my wits end trying to figure out this problem and I would love help figuring out the problem I am using firefox-developer-edition as a note thanks Ozzy

I've been having problems with some websites not displaying content, others displaying error messages. So have been going through the Troubleshooting Mode and diagnostic process.

The cause is the MS CoPilot extension for Firefox.

Useful in other ways as I discovered several other extensions I don't need, hence have remained disabled.

First, I am disabled

When I goto to YT Homepage it will play all the sounds of the downloaded video's when I hover with the mouse.

But I want to hear the sound of that video AFTER I selected that Video or clicked on the title.

Thx!

Issue summary: I lost over 100 sites listed in the Cookies and Site Data section when I simply removed a few websites in the Enhanced Tracking Protection section.

Under the Browser Privacy section, the two subheads, "Enhanced Tracking Protection" and "Cookies and Site Data" serve two distinct purposes—as I understand. Enhanced Tracking Protection will automatically add the URL of a webpage (that you currently have open) to the Enhanced Tracking Protection screen whenever you disable the shield in the search bar. This will turn off tracking for that website until turn you it back on. You can also manually add websites to the Enhanced Tracking Protection screen if you have mulitples to add. This whitelist will stay active until you delete them or click on the shield to turn it back on.

The Cookies and Site Data section further down, allows you to create a list of sites that you want to BLOCK, ALLOW FOR SESSION, or ALLOW cookies and site data to be used, and retained or not. This differs from the Enhanced Tracking Protection section.

Today, I wanted to delete one of the websites listed in the Enhanced Tracking Protection, and did so manually. But since there were only a couple listed (I rarely add to this screen), I simply clicked on "Remove All Websites" instead of "Remove Website." Unfortunately, when I went down to the Cookies and Site Data list (which I use all the time) to add a new URL today, my entire list was gone! I did not remove or enter anything in the Cookies and Site Data screen today, prior to using the Enhanced Tracking Protection screen.

As you can guess, I am sick because I had over 100 sites listed in the Cookies and Site Data section, and lost them all when I removed the few websites in the Enhanced Tracking Protection section. I don't know why or how this happened, but it is worth noting that I did just update Firefox this morning to vs 125.0.2 (from 124.0.2). My list is gone, but does anyone have a reason why it happened and is there a way to prevent that in the future? Or is it some kind of bug with the latest release or an earlier one. (I haven't opened the Enhanced Tracking Protection screen for a long time, so it could be from any past release.) Sorry I don't have more info than that. Any solutions would be appeciated.

I always want the address bar suggestions to start with my bookmarks. Is there a way to control the results? I remember there was something in about:config previously.

I’m using the official ShadowsocksX app to relay network connections through a Shadowsocks server, and Firefox seems to be having compatibility issues. The browser does not load pages when proxy settings are set to “auto-detect” or “use system:” I’m getting the “Unable to connect” error message. Manually setting the SOCKS host to 127.0.0.1:XXXXX does fix the problem, but that also means I have to switch back to “system” whenever I turn Shadowsocks off.

Neither Safari nor Chrome requires manual action to relay connections on the same computer.

On a different computer, I’m using the Outline client to connect to the same Shadowsocks instance. Firefox does not have issues with that.

Hi - I can't get 'pocket recommends' stories to appear in FF on my macbookpro (14.4.1)

I've done pretty much everything I can find online including the below – nothing works

ANy ideas?

Type "about:config" in the address bar and press Enter Click "I accept the risk!" to proceed In the search bar, type "browser.newtabpage.activity-stream.feeds.topsites" and press Enter Right-click on the "browser.newtabpage.activity-stream.feeds.topsites" preference and select "Reset" Restart Firefox and open a new tab to see if the Pocket Discover tiles appear.

Hi. Strange request I know because Firefox is working perfectly but Google has failed me.

We have a printer/copier in our small club. The IP address assigned is 192.168.1.125. Typing this into a browser should bring up the copier admin dashboard.

When I do this using Firefox everything works fine, BUT when I use any other browser such as Chrome, Edge or Opera I get the "Cannot connect" "Error connecting" etc message.

I removed Bitdefender antivirus and disabled Windows Defender but it's still the same.

Any network people who can point me in the right place as to where to look or report to the correct forum.

Apologies for posting in here when it's not a FF problem.

Thanks in advance TQO

I'm on a Mac running Monterey 12.7.4. I've been using Firefox for years with no issues. All of a sudden Firefox can't load any websites. Message: "We can’t connect to the server at www.XXX.ca." But Safari loads all websites with no problems. I can't figure this out.

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

Am trying to update my email address. When I try to make the secondary the primary, it wants a verification code entered. The field for this code will not let me paste it or enter it manually. Will this glitch be fixed soon?

Others asked and were pointed to extensions. As long as extensions get access to my pages, I'm not willing to use any. So, is there an option in advanced settings, to return to previously viewed tab when I close a tab? Thanks, Cat

I am a Salesforce (improveit! 360) user, exclusively browsing with Firefox for over 12 years without any problems. The most recent Firefox update 125.0.2 (64-bit) has caused an issue with my staff calendar. I have reached out to improveit! 360 they are a force.com developer and they will not help, said the error is caused by Firefox interpreting the code. I have figured out a work around to get the calendar to load correctly for a short term solution. Below is a screenshot of the error, any help would be greatly appreciated.

Thank you for your assistance in advance. Since I updated my browser, I've encountered some issues when trying to maximize the virtual screen in my tv. I use a Mac and connect the screen to a web TV to watch YouTube in my big tv. However, when I click to maximize the window, the connection becomes unstable, and the virtual screen disappears every time I click the YouTube icon to do this. This problem never occurred before. I would appreciate your help in resolving this issue. Please let me know if you require any additional information from me.

I noticed that FireFox downloaded a Firefox HTML Document called GnT6qZGD with a size of 0KB, during this time I had tabs open from both https://wago.io/weakauras and https://www.curseforge.com/

Scanned it with Bitdefender and it was clean and when editing in notepad it is empty and a blank page when accidentally opening it.

Then completed a full system scan and it come up as clean.

I have 2 questions,

1st, Is this still a bug in Firefox that appears to have been reported before? 2nd Should I be concerned about it?

Thank you

When choosing biometrics for 2-factor authentication, sometimes Firefox will only prompt for a physical hardware key, and Touch ID does not work. Support for built-in biometrics is inconsistent.

For reference, I am using Mac OS Sonoma 14.4.1 with an ARM processor.
