In a recent Firefox browser update, my ability to reference my home router by name via the Windows HOSTS file stopped. I can ping the router by name from a CMD window just fine but keying the name into Firefox now fails. Images show the two forms of failure - a 500 Error when DNS over HTTPS is enabled; a 'having problems' error with suggestion of www..com alternative when DNS over HTTPS is disabled. Neither is the least bit helpful.

I can't imagine what changed and I can't find a prior support response that gives any clear ideas.

When running a remote desktop connection, if the the remote computer has a web player running (YouTube, Spotify, SoundCloud, etc.) it will stop playback and audio will stop outputting from the remote computer.

However, you can hit play again on the web player and it will resume playing. But once you end your remote desktop connection the player will stop again and all audio or video output

There is a post here (https://mzl.la/3Pg6xU3) that stated you can change "security.sandbox.content.level" value to "2" but this did not work.

Any ideas?

I'm having this insanely irritating bug where when I have my DAW software, specifically FL Studio, open at the same time as Firefox, and I try to pull up any sort of video or content, whether that be Youtube, Twitch, Dropbox or Google Drive files, or even videos just being queued up by Twitter or Reddit in the background, there'll be a chance that Firefox sort of "crashes," and goes all white (or grey with the default theme) for up to dozens of seconds, and forces the video to reload, or it just breaks the player.

​I need to be able to use my browser and my DAW at the same time to preview and drag files into it, and to work with video, so closing one or the other isn't an option. I've tried everything short of a drive wipe and OS reinstall; I've tried making a new profile, disabling extensions, disabling hardware acceleration, the troubleshoot mode, and even a complete wipe and reinstall of both Firefox and FL Studio. Nothing has worked.

​Has anyone else had that issue and hopefully been able to fix it? Or does anyone know any way to alleviate this? Thank you!

​I'm using Windows 11 Pro on a Framework 13 with an AMD 7840U with all the latest updates and drivers, and can provide specifics if needed.

Greetings,

I had stumbled on a list of your fixed bugs lists and noticed updates were made on my keyboard.

On 03/09/2024, my left shift key, z, X and C keys are not working.

I have to copy and paste those letters from other documents to type it here. Do you have any idea how those keys stopped working?

Thank you in advance for your input.

Firefox will not load images at launch with my VPN on. And text is all garbled. Other browsers such as Chrome and Safari work fine with the VPN on.

On a MackBook Pro, M3 chip, Sonoma 14.3.1, and the latest ver. of Firefox.

MacBook Air, OSX 12.6.1 Firefox 123.0.1 iPhone 12 IOS 17.3.1

Using a wifi hotspot from my iPhone, Firefox on the Mac gives me "Hmm. We’re having trouble finding that site." for all sites. As if there is no internet connection Chrome works fine, other internet based apps like Skype, Whatsapp work fine (but Mac Mail won't connect either)

Before IOS 17, everything worked fine.

Is there a setting in Firefox that is responding to something new in IOS 17's hotspotting feature?

Thanks

Example Video Address is "https://www.bilibili.com/video/BV1LF4m1E7kB". Open the URL and watching 2 or more videos can repeat the problem.

The first image shows the memory usage when I first open the video URL. The second image shows the memory usage after I watching some video. The memory usage can be even more as you keep watching.

I can help debug the problem if need. Can any one help? Thanks a lot.

Hello! I have two FB accounts, one business and one personal. Since they started their new login procedure (trying to get access to your other devices), I can only log into my personal account on FF, because FB gives me other options besides logging in on another device, but on my business account, it doesn't. I work on my computer and refuse to give FB access to my phone because of all the annoying spam and notifications, and because I don't trust them.

I can only login to my business account on Chrome, and I don't trust it either. Is there a setting I need to change on FF to be allowed into this other account?

TIA

Long time technical, firefox user. One day starting firefox caused the system to slow unacceptably down. No changes before other than a possible background update from v122. Tried to do a Fresh Firefox v123, but firefox is attempting/constant localhost connections (ports in 40k-65k range) (attached screenshot).

It's on a Windows 10 desktop, uninstalled Firefox v123, manually deleted %appdata%\mozilla and %localappdata%\mozilla, reinstalled firefox, as soon as firefox.exe executes, I get constant localhost connection attempts from the "firefox.exe" process (Process Monitor image attached).

ran about:processes, found it was the "Network" category causing the problem. Permalink to report... https://share.firefox.dev/4972weA

Ran dism, it found no system files had issues. Only firefox has an issue, the system is great without it running.

Is this a bug?

What does firefox use the localhost connection for?

Is there a secondary component that is required by firefox that it is not running on execution that it is looking for?

I have the same problem https://support.mozilla.org/en-US/questions/1421734 it's not a pdf. If I want to print a shipping label from eBay using Firefox nothing happens if I try to make it bigger. I can make it smaller but it is too small to begin with. If I use Brave or Edge (using the same printer) it works I can adjust it and make it bigger up to 200 %. I have already reset the printer options in Firefox and tried when disabling all add-ons.

When you switch the language in a text field, the focus on that text field is lost and the focus goes to another browser tab. This only happens if at this time a video is playing in mozilla in picture in picture mode with the Always on top option enabled. How to fix it? (Ubuntu 22.04)

Firefox is frequently deleting entries made on websites. I am entering information in boxes (like this one) on websites when suddenly FF bails out, the data vanishes off the screen and leaves me back where I started. It happened several times attempting to post this question. This seems to have something to do with hitting a key or the space bar--but what and why eludes me. I have tried changing settings on trackpad and mouse without any impact. Although this is a recent issue with a new computer, the issue does not occur using the same computer on Chrome. Any ideas?

When I'm viewing a PDF from within Firefox and try to print the page, it shows a smaller version between 1/2-3/4 of the size of the paper. I have "fit to page selected" and this doesn't change it. I try a larger than 100% scale and this doesn't change it either.

However when I download the pdf and pull it up using Acrobat it allows me to print full page, fit to page, scale, etc no problem.

Initially I thought it was my printer, but I removed and reinstalled the drivers for the printer and I don't have this issue with any other program except for printing from Firefox. It's almost like the Firefox browser has too small of a page default set so that it's fitting to a page, but the page is smaller than 8.5x11 printer paper.

How do I fix this?

In devtools when i search in all resources it takes 2+ minutes to find all of the matches, while chrome is near instant, same website. theres around 200 requests. On my laptop it completes faster though so im a little confused.

Using Mac OSX El Capitan 10.11.6 and Firefox 75.15.0 esr

I have a number of desktops defined in "spaces" and each app goes into one. Something odd has happened with Firefox.

When I select a different Window from the Window dropdown, or from the Dock, sometimes there is a "sliding sideways" effect.

And if I go into Firefox by going to the Dock and tapping its icon - it goes to one window; BUT if go to the Dock and tap again, it changes to another window. I think, always the same two.

So its sort of behaving like "spaces" does, but when I view all the "desktops" in the selection view at the top of the screen, I only see one containing Firefox windows.

Its really annoying when the window changes like that, and I don't know how to get them into a single grouping. I have quit & reopened many times, but it persists.

If I knew which of the Firefox Windows were in each of these glitchy "pseudo-groups" then I might quit all of one group, and then re-open them. Not sure if there are just two such pseudo-groups, or more.

It is sort in the background like a page behind the main screen I am viewing but it causes Firefox to crash. I have seen other posts say disable hardware acceleration, but mine is disabled, others say disabled extension, but I only have ublock! It is not my graphics card as it is all up to date. My laptop is new 6 months old.

This brings up something I have been trying to fix for more than a year. When I click on the email link "Start with a free scan", google.com appears at the bottom left and nothing happens, not just with your link but with all. I have waited many minutes just to see if it will link. Sometimes, after minutes, it connects. I have been trying to get Google out of this in "mailto" but cannot. If I right click "open in a new page", google does come up, the target site does (I think) and we move along normally.

Can't you fix this? Google it and you'll see it everywhere. Mozilla has a suggested approach online which does not work. Please help all the AVG and Firefox folks who suffer with this.

Thank you,

Hi, lately I have been having issues with updates. When Firefox browser in MacOS gets update, it ask me to sign in to all platforms again. This wasn't the case at all before.

Looking forward to the responses.

Thanks!
