I cannot get screen share, webcam share, microphone share to work with my default profile. I get a Cross Origin Request Blocked. If I create a new profile everything works as it should even if I install all the same plugins. I have tried changing security..cross_origin in about:config and it makes no difference.

I have a lot of tab groups and sorting in my default profile, so I'd prefer not to have to set that up in a new profile. Importing to a new profile ends me up with the same issue as above.

This error is profile specific and I am wondering if anyone knows the specific profile files that I could regenerate, delete or replace to tackle this cross origin blocking.

Also I've disabled all my plugins, and enhanced tracking protection on the default profile and it still does not work..

Thanks.

Need to clear all previous activity [history, cache, etc.]. I create websites. Do NOT save history. Option turned off. When I bring up a changed website, I see the previous version or the one before that half the time. Rebooting PC does not clear it. Am tired of playing browser roulette, trying to find a browser which will A. Show the latest version. [which is being displayed on other people's devices] B. Perform the desired action as designed by the product creator [which works on other servers and devices, and even sometimes on my device using another browser] I am not skilled at seeing physically thru other people's eyes, only imaginatively. My partner is 200 miles away in another state. We don't always see the same, even when the display is identical. Am starting to create 2 versions of sites, a .org and a .com and explaining to people WHY. I think the "don't save" does not work. It merely turns off creating an index of the viewed material and leaves the viewed material in cache. And re-displays the initial data eveytime, no matter how many updates. Thank you.

i have just downloaded Firefox and i go to open in and it flashes open an close immediately. the occurs every time that i open the program. i have reinstalled it multiple times to see if that's the issue, used the Microsoft store to download it, the website, i tried to get the beta that didn't help and i was just wondering what the issues was and wondering if you could. i looked in the error message folder as well and its empty.

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

Hello,

I've just downloaded firefox, making the switch from chrome. Doing so I've migrated a couple of tabs and extensions I had. Totally it was 50 tabs, with 6 extensions, I've downgraded now with the switch and it's only 37 tabs and 2 extensions, even so firefox is using more ram than google by a large amount. With 50 tabs open, chrome was using 1.5gigabytes of memory. With the same 37 tabs and extensions, firefox is currently using 6 gigabytes of memory.

The tabs used are from reputable sources, so firefox shouldn't be breaking on these websites. The extensions I am using at the moment on firefox is, Ublock origin, Dark Reader.

As far as reputation goes, firefox should be using less Ram than chrome. Is there a setting I should know about to lower such performance issues? Firefox acceleration is ON.

Thank you for any answers.

Immediately on update to 96.0 this afternoon, multiple sites failed to load - Google(Maps, News etc), Yahoo, Flightradar24 etc - others partially loaded - then sat there blank. Explanation of errors is NOT clear -

Is it possible to revert to previous version? Everything seems to work fine when using EDGE!

Hello all. Since the update to Version 113.0 I have been getting an error in my Event Viewer which is Event 2 Firefox Default Browser Agent . I am now on Version 113.0.1 and still get this error. Firefox is my default browser. Below is an image of what I see in my Event Viewer and also the full view of the event itself. I seem to not be having any problems with the browser but I was wondering if anyone could shed some light on why this is happening or forward to the Devs.

Respectfully, Don

The latest example is the button to sign into LinkedIn. It is not working in Firefox, but it does in other browsers. I have other examples just from today. I have used firefox as default for many years. I assume this is a security thing, but these are basic links. I have no add-ons or other complications. Most times, I do not even realize there is a problem, but when I feel something is wrong, I try another browser and it works. Thank you.

Whenever I attempt to access DRM content such as netflix or spotify I am notified that the WidevineCdm plugin has crashed. I'm running firefox version 101.0.1 on Kubuntu 22.04, I am running the debian package release, but I had this issue with the snap version too. I've submitted crash reports, but they're all "EMPTY: no crashing thread" (https://crash-stats.mozilla.org/report/index/20af09a5-6bc4-4719-9242-38f5c0220614 here's one).

Just now, after a massive and catastrophic SUPER-MELTDOWN-crash that arbitrarily decided to absolutely murder my day, ALL my tabs and windows and ALL history of "Recently Closed" tabs and windows is gone!

THIS IS COMPLETELY UNACCEPTABLE!

What is the reason for the existence of a SYNC feature if it isn't to MAKE SURE that a record of open tabs and windows is SECURELY maintained no matter how many times the application crashes, so that AT ALL TIMES, this information is kept INTACT, regardless of the state of the end users device? That is BY FAR the most important part of the sync feature! Are you telling me that there is no backup process of that information?

This is the kind of thing I never expected from you guys at Mozilla. I've been using Firefox for MANY years because I trust what you do. Today that trust has been SEVERELY and BRUTALLY wounded, most likely beyond repair...

I need you to fix this...

I need you to recover that information for me and I need you to make sure that what just happened could never, ever happen again unless God himself caused every digital storage unit on earth to disintegrate.

I'm on Ubuntu 22.04 which is using the snap package of Firefox.

It seems that I cannot open local files in the /tmp directory. When I place a test.html file there and run `firefox /tmp/test.html`, it returns a file not found error. Why?

I don't have the problem with files in my home directory.

Hi, so my problem was exist for several times both on my PC and laptop and can't figure it out keyword to fix my issue and tbh i don't know what trigger this behavior. When browsing sometimes came situation can't type anything using my keyboard, even when outside firefox.

my current workaround to encounter this, i just need open any web with place I can type like search bar or text box and type there then back to normal (so I guessing it's maybe related to when I open web with this kind search box then move to other tab it's stuck on that box? but i can't make sure, it just happen randomly but often). and I don't know if this issues related to windows or just firefox because I didn't know the trigger so i can't recreate this on other browser.

If anyone know how to fix this, please help me.

thanks in advance

I had the same problem like the link below when I use firefox.

https://www.reddit.com/r/firefox/comments/tjxh7s/videos_freeze_when_window_isnt_in_focus/

So, did what the instruction says and it solved the problem regarding discord.

But, since I changed that setting, firefox doesn't remember my google login or dark skin settings of other websites (it was always automatically logged in when I use YouTube. Not like it remembers the password).

How can I solve it? I resetted firefox multiple times.

Hello Whenever I start a download, it immediately crashes, no matter what you do all downloads fail. Tried solutions that didn't work:

• refresh ff,
• delete profiles,
• uninstall + reinstall.

The BBC website believes I am in another country, other than the UK. It currently redirects from bbc.co.uk to bbc.com, with some content no longer being available.

I have checked my IP, and it is currently a UK-based IP address. I do not have any active VPN profiles.

I have refreshed Firefox, deleted profiles, and redownloded but still the issue presists.

This problem is not reflective on any other browsers on the same machine.

Grateful for your help.

This is the BBC's advice, which I have followed - https://www.bbc.co.uk/contact/questions/behind-the-scenes/website-domain-change

Hello, I am using a personal PC. So I don't require the Firefox to be managed by an organization. In settings it shows "Your browser is being managed by your organization" . On clicking on it, it says "The Enterprise Policies service is active but there are no policies enabled". I have attached screenshots for the same. Does any one know how to resolve this bug?

Hello,

I've spent several hours today trying to fix FireFox slow start up on my system. After start up (about 2 full minutes), everything works normally. The hardware is an ASUS A88xm-A MB, A10-6800K processor, 16G DDR3, runs OS and programs off an SSD. I worked through all the slow startup suggestions, ran memtest (0 Errors, 1 Pass), disabled all add ons, (even the OpenH264 video codec (I use the onboard HDMI, no graphics card)), turned off hardware acceleration, etc. When starting in troubleshoot mode, less than 30 seconds, (acceptable), but I really don't know where to begin with the "More Troubleshooting Information" when I look at the table generated by it. There have been no other problems to date with the system, and the long start-up time began with 20.04 Ubuntu (about a minute), then got worse when I upgraded to 22.04 to try to solve THAT problem. Currently running FF 104.0, and the update page says wait for a distro update if that is how it was installed. I believe 104.0 is the latest Linux 64b version though. All updates to the system are done as soon as I'm notified of them. there have been none since the upgrade a few days ago.

Any suggestions? Gotta get some sleep now... TIA, Dave

I'm running Firefox 99.0.1 on Ubuntu 22.04. Recently (I think since I updated to Ubuntu 22.04 about a week ago), Firefox has been refusing to show me file upload dialogs. When I click a button that's supposed to give me one, nothing happens.

This has been happening with: - The "attach files" button in Gmail - A file upload button on Gradescope (website for managing homework assignments) - File -> Open File... and Ctrl+O.

Dragging and dropping a file onto an email in Gmail does attach the file -- it's just that the button doesn't work.

I've tried restarting, and I've tried running Firefox in Troubleshoot Mode -- so far nothing has fixed the problem. What else should I do?
