Firefox Support Forum

Greetings. Lately, I am unable to log-in to some websites. This has started recently, about a few short weeks ago. The Social Security Administration and Electronic Design (magazine) are just a couple of example. I don't get much information from either of the sites. Electronic Design just replies with unable to log-in The SSA site replies with:

"Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit."

I cleared the cache, and reinstalled the latest version, Firefox 120.0.1, 64 I am on Windows 10 Pro 64, latest update AMD Ryzen 7 8-core 16GB RAM 1TB Samsung m.2 2280 system disk

Note: I have no issue logging in to the SSA website using MS Edge, but I'd rather use Firefox, which has been my default browser since Adam & Eve hit the earth! Your assistance would be appreciated. Thank you. Sam H. Electrical Engineer (248)677-1039

Animation triggers my migraines.

Man websites use transition and animation timing functions such as "ease in-out" to animate the interface. I try to block this. Among other tools I use userContent,css, including the following:

• {animation-timing-function: step-start !important}
• {transition-timing-function: step-start !important}

This works to de-animate regular css elements, but not ::before and ::after pseudo-elements.

The current css standards do not apply user css to pseudo-elements. I've written to the WCAG about the issue.

https://bugzilla.mozilla.org/show_bug.cgi?id=1865572

https://github.com/w3c/wcag3/issues/40

But I really really need some way to de-animate these, because they trigger my migraines. Aside from css fixes, I often reduce the frame rate in about:config, but can't always do that, disable smooth scrolling, disable animated gifs and animated pngs, disable autoplay, block various non-scrolling elements using either css or uBlock Origin, etc.

Since the last FF update (115.5esr, Windows 8.1 Pro) I keep getting the following error message when I try to access one particular website:

The page isn’t redirecting properly An error occurred during a connection to www.doordash.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I have tried virtually all the solutions suggested online. I have cleared my cache, deleted cookies and site data, and I have tried to access the site using Troubleshooting mode, all to no avail. I contacted support for the particular website and they have no difficulty accessing the site with FF.

I can access the site in question with the Chrome browser, so the issue would appear to lie with Mozilla. I use this particular site frequently and would much prefer to continue to access it using it with FF, as I have done for over a year. I just installed Chrome on my Windows 8.1 Pro PC solely for the purposes of accessing this one website.

Help in resolving this issue would be greatly appreciated.

Firefox 120.0 on openSUSE Tumbleweed.

Google Maps (https://www.google.com/maps) results in CPU being pegged at 100%. No other tabs open. All I have to do is load the URL and do nothing else. This behavior is repeatable. CPU stays at 100% until tab is closed or browser is shut down. Sometimes the browser will hang and its PID has to be killed.

Offending process:

Just opened up Fireox and everything has gone - all bookmarks and folders, toolbar with shortcuts, all of it. I am not a technical person. What do i do to get it all back? Thank you Harry

Firefox is my browser, and Outlook my email program. After years of troublefree access to Kickstarter, I now cannot link to the site, neither by Google search, nor by responding to an email link sent to me by Kickstarter. Instead, I get a message which reads:

'You are sending too many requests to Kickstarter at this time. Please contact support@kickstarter.com if you continue to see this error.'

I have contacted Kickstarter, but their response is that the problem probably lies with my browser. Do you have any idea why this problem should suddenly have appeared?

For the past few days, when I try to log on to PlayStation on Firefox, the sign-in page sits on a loading swirl after inputting email. There's a clear memory leak shown on Task Manager. The menu bar's right-click doesn't draw properly. FF can't be closed and needs to be terminated. The only extension I have is uBlock Origin disabled for this site.

This website works on Edge.

Attached is the broken menu from right-clicking the menu bar.

This issue started with a (frustrating) set of steps following a page which wasn't displayed (https://www.ziggogo.tv/) - the screen remained black. Refresh solved it but the reinstalled plugins didn't show an icon and did not work at all. I de-installed Firefox, installed some old version from an update, installed all plugins and then updated to the latest version. Now finally everything seems to work- except that the 2nd and next windows show at a quarter of the size compared to the first whchi show correctly. I've tried everything I could think of with xulstore.json in the correct ..\AppData\Roaming\Mozilla\Firefox\Profiles\ subdirectory but nothing helps. I deleted it (which requires you to re-check that you want a menu bar),when I though for a moment it worked, made it read only (which means Firefox makes a .tmp version of it), manually changed the content (e.g. to "main-window":{"screenX":"4","screenY":"4","width":"3840","height":"2048","sizemode":"maximized"}}} matching my 4K monitor but nothing helps. And no, Ctrl click the Close button doesn't help either.

I suspect that it is a (maybe reintroduced) bug in a later build. I don't update often and I haven't seen this issue before.

Anything I can do which I haven't tried?

I'm trying to load https://bfjoy.com/ and only Firefox is redirecting my typing of 'bfjoy.com' as an http: website instead of the correct https:

Why is this? I assume DNS but what is Firefox doing to redirect to the unsecured site that other browsers aren't?

Firefox tells me to close program because Firefox is already running. When I close Firefox then re-open Firefox: same message. When I check Firefox in Task Manager, there are anywhere from 6 instances of FF running and sometimes up to 24. Something needs fixed.

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

I always have the latest version of Firefox today it is 120.0.1

I get several of these and I have Bitdefender antivirus

What to do ?

Hi! I am running Firefox on an old MacPro5,1 with MacOS Ventura using Open Core Legacy Patcher. The graphics card is a NVIDIA GeForce GT 630. So overall it's a pretty old setup but everything works fine. However, since day one, I've been having rendering issues with some (not all) videos on Firefox. These videos include some but not all YouTube videos, some embedded animations on websites, and every live stream video. The workaround is pretty straightforward: everything works fine on Safari and Chrome. Still, I am wondering what the issue could be, any help would be appreciated. Attached are two screenshot of what the rendering issues look like.

I just realized that my user agent string is wrong (for instance, it says that I am on OS X 10.15, even though I am on 13.6, not sure if that makes any difference at all.

Hi, I got a new laptop recently and ever since then I've been experiencing this problem. Websites like https://tabs.ultimate-guitar.com or https://ukutabs.com offer the option to autoscroll, so that you can play your instrument without having to pause your playing and scroll further yourself. This feature hasn't been working for me ever since I got my new device and since it's various sites, I suppose the problem must be in the browser itself, I just can't figure it out. In the case of Ultimate Guitar, when I click autoscroll, it does move slightly, once, but then stops again, and you'd miss the movement if you're not paying close attention. I can switch between various speeds on this site as well, but it doesn't do anything. In case of Ukutabs, there's not even any kind of response from the site when I click the option. I tried turning on and off Firefox settings concerning autoscrolling and smooth scrolling, but nothing solved my problem.

Thank you for your time and energy, everyone!

I have recently (today) installed a device (Mini Wireless USB adapter) on my desktop computer. I am now connected to my ISP modem wirelessly. I have been using Firefox as my browser for many years (ten?) and have not had a problem until today. When I attempt to go to a web site I get a notice that says: "Unable to find the proxy server. Firefox is configured to use a proxy server that can't be found. Check the proxy settings to sure they are correct. Check to make sure your computer has a working network connection. If your computer or network is protected by firewall or proxy make sure that Firefox is permitted to access the web."

I am able to get to any web site I choose when using another browser. I am also receiving my emails, and able to send emails. So I know the computer has a working network connection. When I have visited the Mozilla support site (having to use another browser) I see advice that shows opening the Settings page and getting to the Proxy settings. When I open my "Settings" page from the menu on the Firefox home page upper banner I do not see any option to get the Proxy settings. How do I access the Proxy settings page? Or how do I access the Firewall settings? Don't forget, I cannot open any web page from Firefox.
