Firefox Support Forum

Hi, Since yesterday Firefox won't play any live video streams on any website. An HTML5 error message shows up.

I've tried upgrading Firefox, disabling Add ons, starting in safe mode, completely uninstalling and starting from scratch and installing and deleting Adobe flash as a last resort.

I made sure everything was up to date on my laptop and they play no problem on other browsers. I just can't work out what's wrong with Firefox.

FF is unable to navigate the grocery purchase procedure for Walmart. It has cost me hours and hours of tech support and re-entering data over and over, and also cost me hundreds of dollars paying for groceries that were supposed to be free, and my limited income doesn't have that type of fiscal flexibility. How do I get FF to look into this and fix it?

I seem to have signed up for a product that costs $2.99 per month. I don't know what the product is and I don't use it. Mozilla provides no way to cancel this charge that I have been able to find.

Just curious what the text file "alternateservices.txt" has for function. It is located in the Firefox user folder on Windows 10 systems.

Would be grateful for answers.

When I try to use my existing Firefox account login on my new Win 10 laptop, it tells me the password is incorrect. I have tried this both manually and with a password manager; fails either way. (This question has been posted using my Win 10 desktop PC, using that very login.)

Hi, I just updated to Firefox Developer 83.0b4 and the two-finger scroll sensitivity has been drastically reduced with no clear way to reconfigure it. I've spent the past 30 mins tweaking scroll settings in `about:config` (restarting FF after each value change) to no avail. In fact, it doesn't even appear that enabling/disabling `general.smoothScroll` or `general.smoothScroll.mouseWheel` have any noticeable effect, let alone the many other options listed. Are there any pages that describe the myriad options in `about:config` so that I can take a more measured approach to troubleshooting this issue?

What changed? And why? Chrome did this same thing at v68 without ever providing any way to configure it and FF has been my main browser since. I'm just trying to understand how such a significant input change can happen overnight without any explanation or any way to fix it.

As the title implies, I am unable to open any local files on Firefox. The tab just keeps loading forever and using up all available memory until it crashes the tab. (the browser still remains operational, since the crashing process is a child process of the main browser)

I took a look at the process in GDB and it looks like it's hanging in `read () at /usr/lib/libpthread.so.0`, called from libxul.so. (possibly a spinlock, since it also grinds one of my cpu cores down) I've checked and this problem is not related to my profile, settings, or extensions.

I'm at a complete loss for what to do now to fix this, since I don't have the time or disk space to build a full debug build of Firefox and figure out what's going on.

Hi, With Firefox 81.0.2 64-bit running on Windows 7, I can't logout from my account on a very specific site. If I delete the 2 cookies the site wrote on my computer, I'm then presented with the logon window and I'm able to login again but not logout until I delete the 2 fresh cookies the site just put on my computer during the new session. Should I log under a private window, nothing being written to my computer, log out is always possible. I'm also able to log out from my current session with an older version of firefox (50.1.0). This also close the session opened under Firefox 81. At the moment, only one site is behaving like this. I first asked the support of this site. Here's its reply: <<That is an interesting problem you have there! It might be that your session wasn't properly removed from our server but I know that we restarted our webserver 3 days ago, so that should have resolved itself if that was the problem. I don't have any other suggestions, but if a private window works, this suggests an issue with your cookie management of the browser.>>

Please may you help ? TIA

I have been logging in to M&S Internet Banking for ages. Now I can't. I phoned M&S support and they said try a different browser. I tried Microsoft Edge and was able to log in normally. I don't want to use Edge I want to use Firefox. Any help will be appreciated. Andrew M

I've tried in a new installation of windows and firefox, if you load more than one digital certificates in the "your certificates" tab, the browser gets stuck in the first digital certificate that you have selected. No matters if you close the browser, when you open it again the browser acts like the certificate is already selected without being prompted when you try to enter a webpage that needs a digital certificate.

For example: Spanish Social Security https://sede.seg-social.gob.es/wps/portal/sede/sede/Ciudadanos/CiudadanoDetalle/!ut/p/z0/rU_LDoIwEPwVOHA02wIhciTGEJQmGkOEXkgDBeujPFqN_r3UO5y8TDKzk5kdoJADlewlWqZFJ9l94gUNSg8HPg4RTmOUbFGUkX0WekcvTjCcuIId0AWTG5gUdyQb0gLtmb6shGw6yA2OD66sj1XxUYtGVKzuFOQIz56gENdhoBHQqpOavzXkite8_DEpJo-DjOCgSjxrVjNplJk4B803LW-ahv_7FRfhdeBDf4vPh7QhKrLtLwe74DE!/

I have marked the checkbox "ask every time" and disabled any master password.

Any help is welcomed!

I can reach Virgin Mobile Canada, that is I can login and then see my account, with Vivaldi and Chrome, latest version, but now with FF 82.0 I cannot do so. Trying to login just results in a coming back to login page over and over. Seems like something funny has happened with latest FF, as this was not a problem before.

Navigating on Ebay causes The page isn’t redirecting properly error on some pages.

For example I'm unable to navigate through categories but searching and clicking on a search result seems to work fine.

While viewing an item clicking on a subcategory under the search bar generates this error 100% of the time, everything seems to work great on other browsers though.

Sometimes I'm unable to even view an item when accessed from a google result or even an sponsored listing.

I have tried clearing cookies and cache, allowing ebay to set cookies, disabled ETP, run in safe mode, private mode, reinstalling firefox and finally windows but still the problem persists.

I work in IT for Cisco (even though my account is using my own email). We have over 100 cases raised where users have updated to V82 and then cannot load Firefox.

We have 2 fixes currently:

1 Downgrade Firefox - but we don't want to do this. 2. Load a new profile.

Is there anything else we can check on. All our users are on Windows 10 Enterprise, there are several versions used from 1803 to the latest, we have a spread of Windows 10 versions where this issue is experienced.

Should there be a better way to resolve this or if there is a root cause that's been found I would be very grateful if this could be passed on.

Hi,

I'm trying to get into my onedrive through firefox, but it won't login, as described in the title. I log into my office 365 outlook mail (which works perfectly fine), and then I press the dots in the upper left corner and click on onedrive listed in the apps. I tried removing cache, cookies and all that, I tried reinstalling firefox, but nothing worked. For reference; it does work when I use edge or another browser, and it also works when I use firefox on another device.

Can anybody tell me what the problem might be? Thanks in advance!

Georgia DOT recent traffic upgrade (511ga.org) no longer works with Firefox. I can not see traffic cameras and does not remember settings between sessions. It works on my iPad and windows explorer. I'm running Windows 10 Home 64 bit with Intel i7-7700. Thanks for any help you can give me. Jay

Hi, I have a returning bug in Firefox. I am getting the tool bar in order and immediateoly after restarting my computer all is sorted again in an alphabethic order. I did most of the advices I found on the help sides. But it is not ok so far. It happens always again. Who can help?

I downloaded my browsers from the developer sites. I have two Firefox icons on my workspace - one on the desktop and one in the taskbar. Although they appear to be the same icon, they each open two different versions of the Firefox browser. The desktop icon opens the 32-bit and the taskbar opens the 64-bit. I don't like the consistent overriding of my preferences when I open the 32-bit version I often open the browser to find my bookmark toolbar has been deleted. Over and over. Recovering my bookmarks bar is time-consuming and tiresome The 64-bit version has been consistent. I wanted to create a 64-bit desktop icon and have not found a way to do it. When I try to create a desktop shortcut for the 64bit Firefox (it only appears on the taskbar), I have mysteriously got Opera icons for each try. When I create a desktop shortcut from the open home page in the Firefox browser, the shortcut appears with the Startpage or the Opera icon. I learned that icons have their own folders.... so I found and opened one for Mozilla Firefox -but the folder has only three Opera icons and one Startpage icon. I have no idea how the taskbar 64-bit icon has kept its original Firefox appearance from the original install, nor how the 32-bit icon in the desktop has also maintained its appearance. I cannot find any other icon folders in any of the other Mozilla folders. Any suggestions short of starting over with uninstalling the lot and reinstalling?
