Firefox Community Forum

After tinkering with about:config (shouldn't have...) the background of every page that does not specify a body background color turns the color of my theme background color.

Using the firefox color pipette says its white, but it clearly isn't.

The theme i have is dark, making any page that expects the background to be white unreadable (without DevTools -> Body -> background-color: white)

I haven't been able to find the config that fixes it.

When watching a HDR video on Firefox on Mac (in this case, a Mac Mini M4 running Sequoia) - freshly installed, connected to an AOC QHD HDR monitor via USB-C->Displayport cable, the video appears overexposed with large patches of white making the video unwatchable. This applies to all HDR video on Youtube.

Watching the same video on Safari presents no such issues - HDR video plays as expected.

My laptop unexpectedly closed Firefox after it crashed and upon a restart I re-opened Firefox, which normally restores all my open windows/tabs from the very last session no problem whenever it force quits due to laptop crashes. But this time when opening, it restored windows/tabs from almost a month ago. I closed Firefox and checked the sessionstore-backups folder: - the recovery-backup files are from the session date I just re-opened with old tabs - the previous.jsonlz4 file is from about a month ago and seems to be the reference point used when restoring tabs rather than my actual last session

Is there any other file or method I could use to recover my actual prior session tabs before it crashed?

I have not re-opened Firefox since quitting the browser after seeing it restored the old tabs.

Thank you in advance!

I confirmed with my host provider that my website is in a secure environment, but when I access three form pages that end in "php" there is a broken padlock icon in the address bar and says that the connection is not secure.

I checked other browsers (Edge, Chrome, & Brave) and all show a secure connection. So this only happens in the Firefox browser (v141.0). I'm using Windows 10 64bit.

Has anyone else had this issue? Any suggestions on how to fix?

The form is how my clients order on my website (no financial info is entered on the form, just data), and I fear that if they are using Firefox and see it's "not secure" they will leave.

I am using the Firefox browser on my iMac. Suddenly, I am not able to 'sign in' or access pages of common websites. I am getting blank pages or pages with the ever-circling ball when trying to access websites, like homedepot.com, shutterfly.com, etc. I can access them via safari.

I have gone through the Troubleshooting steps, have Uninstalled Firefox and Reinstalled, etc. What is happening with my browser?

So, this has been going on for a while in multiple devices.

If for some reason the network that I'm connected to loses connection to the internet and I connect to another network that has internet access Firefox fails to recognize that there is internet access from another network. The only way to get Firefox back online is to close it and open it again, losing any work that was being carried out.

This happens with multiple devices on different networks

¿how do you get Firefox to understand that there is internet access from another network? (like when switching from wifi to a cabled connection)

When I access Facebook via Firefox browser there usually are issues - site does not load properly, videos stop working, and more. I do not encounter the same problems with other browsers.

I was on a website and noticed I was signed out, so I went to log in, but the browser did not display the username/password like it usually does. I clicked on the hamburger menu to go to my passwords and I noticed that it said "Account disconnected" at the top. I figured this was the issue, so I clicked it to log in. After going through the forgot password steps, I got logged in to Mozilla. Firefox then prompted me if I wanted to save that password and I clicked yes. I then went to the password manager and the only one listed was the Mozilla password that I just saved. After some digging, I found there was a logins.json.corrupt file in the profile folder. I tried renaming it to logins.json but that does not work. I tried viewing the corrupt file, but it was not legible.

Is there any way to recover the passwords or are they gone for good?

Sending this using Safari because Firefox is totally messed up. Firefox 115.24.0esr (64-bit) OSX 10.13.6 High Sierra 2011 Mac Power Book (MPB) with 16 GB RAM. Verizon DSL line, download speed tests from 10-14 Gb/sec but Latency is always 400-900+ msec. No way to measure Jitter with speedtests that will run on my older system, or Bufferbloat now that DSLreports has gone dark.

I want a tool that will allow me to see all the attempts to connect, and packets/traffic, to see it its my old computer going bad, Firefox, the wireless or wired connection to the DSL modem/router, or the DLS modem/router itself, such as a problem with reaching the Domain Name Server (DNS) etc.

I can access the DSL modem/router in the browser, but there isn't much documentation. Its made by Actiontec but customized firmware for Verizon.

The problem persists whether I am using wifi or an Ethernet cable.

My wifes 2010 MBP computer with 8GB RAM using about 6.4GB, running High Sierra and Firefox 115.24.0 (esr) seems not to have the problem at all.

Firefox will show something in the lower left corner, "connecting to..." or "loading..." etc. It can stall with either status.

Search engines would be StartPage or DuckDuckgo. With DDgo, sometimes it just spins forever, but if I click on the URL bar, it drops down another line with the same URL and "--Visit" appended. Sometimes that will load, but seems random.

Some URLs / links open in a few seconds, some spin forever.

I first called Verizon Tech support on May22 about problems (see full exchange of repeated calls & new trouble tickets below). I think, IIRC, this happens to be shortly after I upgraded my Firefox version. They have admitted to PINGs not returning, packet loss, no excuse for the Latency.

I do have a lot of pages/tabs open; Activity Monitor says my memory use is about 14GB, but the Memory Pressure stays low in the green. I also run Thunderbird, TextEdit, maybe Adobe Reader and Excel. But even when I close everything else, the non-loading issue persists. When I shut down Firefox, the memory pressure can go into the red and take a very long time (so I always shut down all other apps first). A recent shutdown stalled & I ended up losing many open pages/tabs, but even the slimmed down load has the same problem.

I have shut off the AddOn NoScript, but the problem persists.

I am unable to sign into the iCloud web page on Firefox. I can sign in on Microsoft Edge, or on the Safari browser on my phone, so this is clearly a Firefox specific problem. When I try to sign in, the page skips the option that verifies my identity and goes straight to a message saying "Failed to verify your identity, Try again" without allowing the verification to occur. The verification would occur if the page would allow it to, as it does in the other browsers I mentioned. This was working fine last time I logged in a few days ago, so this is a new problem. I could switch over to Edge, but would prefer to use Firefox, if I can. Please help me. Thank you.

Hi, I've been using the latest Firefox version on 2 MacBook Pros, and the bookmark favicons are lost when syncing to other devices. They remain on the host device, but are not transferred to the synced device. This is my first attempt at syncing anything in Firefox, so I don’t have any previous settings/files that could be interfering.

Also, “Tabs from other devices” in the Firefox View window lists all of the tabs grouped together, and there are hundreds in the list. How can they be grouped by window (the same way that they appear in the browser), and is there a way to have them sync directly in the windows (w/ fwd/back history in tact) so that each browser appears identically when switching from one device to another?

Thanks

I feel like I've tried everything to stop Firefox from automatically opening when I start my Windows 11 computer.

I've checked: task manager, the startup folder in Windows 11 (shell:startup), The registry under "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run", Settings>Apps>Startup, and also in Firefox under Settings>"Open Firefox automatically when your computer starts up", and under "about:config">toolkit.winRegisterApplicationRestart (change value to false).

Can anyone tell me why Firefox is still automatically launching at startup of Windows 11?

Since the FireFox Desktop update over a month ago (and subsequent patches, currently on Version 142.0.1 (64-bit)), every time I type an email using AOL webmail in the FireFox browser using my Windows 10 Dell desktop, I can only type a few characters before the cursor jumps off the line I am typing and I have to use the mouse to reclick where it stopped typing to again try to retype. This can happen multiple times sometimes as a short as typing only one character before the cursor jumps and I cannot further type. It has now become soooo annoying that I am thinking of changing browers after having using FireFox for as long as I can remember. This does NOT occur when using any other browser, including Edge and Chrome, so it is not to AOL webmail app but rather something in FireFox.

Has anyone else reported the same? Can anything be done to fix this problem before I jump ship to Edge or Chrome on a permanent basis?

Version: 115.27.0esr

Hello.

I 'might' be missing a detail but there is no 'X,' in the top right corner, when viewing Google Reviews.

Clearing cookies, closing and reopening the browser, and rebooting the PC are not successful.

.: Hello. A couple of days ago Firefox stopped displaying thumbnails of YouTube videos. I tried YouTube on other browsers and the thumbnails appeared as usual. On Firefox, they've disappeared, but only on my Windows 10 computer. The YouTube thumbnails appear on Firefox on my MacBook. The attached graphic shows what it looks like on my Win 10 computer.

Any ideas on how to solve this would be greatly appreciated. I have also searched the Internet and YouTube for a solution, but was unable to find one that works.

Thank you.

Hi, I am facing a problem where if i start multiple youtube videos and stop the last one that was started, then audio of all the other videos gets paused as well and the video continues, there isn't any change in the volume or in the volume tab icon. I am getting a bit frustrated here, because i tried a lot of options already and most of them just disable all audio. If anything is needed for testing or something, I will add it asap.
