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.

I need a fix for my ESPN+ account. I can watch live sports and videos but cannot read ESPN+ articles. Everything works great with Edge and Chrome, so maybe I will have to switch browsers.

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.

Very sorry. I saw 2 icons on my desktop and deleted one without checking to see if my Bookmarks were in both of them. They weren't. Do you know of any way to retrieve what I deleted, or should I just put them back as I need them? Also, I set up my original Mozilla account 5 years ago, and don't remember how to add a bookmark panel on the left of the screen.

For the last two months since November 2023), log-in to the Wells Fargo online bank site no longer goes past the log-in page. If I use Edge log-in works fine. I use private browsing on Firefox, but I always have. I have Firefox password enabled, but I always decline to use it for online banking when it pops up (and it doesn't matter if I accept it, still no log-in on Firefox).

I don't want to use Edge but Firefox no longer is working on this task for me.

In my Firefox settings I have selected "check for updates but let [me] choose to install them" but Firefox automatically installs updates while I'm using it and immediately requires me to restart the browser. All navigation thereafter returns a page saying I have to restart Firefox to continue.

It's incredibly annoying to have to then sign in to all half dozen or more sites that I was already signed in to. I'm going to have to abandon Firefox if this continues.

Is it a security setting my employer configured? I think I have the same problem at home.

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.

I frequently need to access a Hi-Fi device on my local ethernet network from https://www.skytune.net For example ... http://192.168.1.68/ or http://192.168.1.62/ (The last 2 digits of the IP change from time to time)

Recently, I keep getting unnecessary security alerts - Any idea why? I have use https only disabled.

I could be with skytune's certificate. I have done everything I can to bypass these errors.

The Disable Protection For Now option seems to be unavailable if the latest Firefox.

I've reinstalled my Windows and once I logged into Firefox and synced my data, I got the wrong bookmarks from years ago, most stuff are of my brother. I tried restoring them, but I only got the date of today which is completly empty. My history looks right, so I guess this is the right account. They're really important, what do I do?

Read about using the Project Fission settings in about:config and only needed to change the gfx.webrender.all to True but I don't see the 'F' when hovering over the current tab to prove it's working.

Dubious as to whether this 'built-in' sandbox is as robust as Sandboxie.

Appreciate any feedback.

Thank you,

Hi, I've set in my settings to use the unified search+url bar, Also I've set Google as my search engine, but when I type a search request Firefox searchs by default an URL, leading to an error every time, I don't know what to change and Ive tried different settings with no change

What would it take for Mozilla to offer a version of Firefox without permanently built-in plugins and/or extensions, and just offer them by selection upon installation, or offer a a registry editor program to add and/or remove them, or simply a paid-for version without them? A paid for browser that could be configured the way a person wants it would be worth the cost of such a browser.

examples of plugins and/or extensions desired to be permanently removed:

Amazon.com Bing DuckDuckGo eBay Firefox Screenshots Form Autofill Google Wikipedia

Refreshing does not work. Disabling does not work as they are enabled after another update, upgrade or by accessing your Firefox account.

Many years ago, M$ was sued for making Internet Explorer an integral part of the operating system yet is being allowed to do the same with Edge today. Just as back then, the browser cannot be permanently uninstalled from Windows, unlike with a Linux OS. Example: Mint will work perfect without the automatically installed Firefox browser should a user want to have a different browser. However, since undesired plugins and/or extensions can be permanently removed, there is no need to uninstall and remove Firefox.

Unfortunately, although I love the Vivaldi browser (which is built from Google's chromium architecture, just like chrome and many others) for any M$ or Linux OS, there are two features Firefox offers still unavailable with Vivaldi at this time. Therefore, Firefox remains my backup browser and for when I would like to use those two features unavailable with Vivaldi. However, Firefox would become the default browser not just for me, but an unknown huge number of users if permanently built-in plugins and/or extensions could be permanently disabled and/or removed because users want less intrusion and thus more security.

Firefox is a great browser. However, not being able to permanently remove permanently built-in plugins and/or extensions is more than a nuisance. Reason: If the built-in plugins and/or extensions can be re-enabled after an update, upgrade, or accessing your Firefox account, then there must be some type of script, sub-routine, program or AI detecting the permanently built-in plugins and/or extensions that have been disabled. That by definition is spying.

What is needed is a method to permanently remove permanent built-in plugins and/or extensions, or at least prevent the disabled built-in plugins and/or extensions from being enabled again.

Perhaps Amazon.com, Bing, DuckDuckGo, eBay and Google and Wikipedia are paying $$$ to be embedded within Firefox which may be needed by Mozilla for the ongoing development of updates and upgrades. If so, a paid-for browser might eliminate the need for Bing, DuckDuckGo, eBay and Google and Wikipedia to be included.

Thoughts and/or discussions?

Thanx!

Suddenly my ISP is HACKING into my browsers to give me "notifications" without my permission (see image), ignoring Firefox settings and UBlock Origin add-on. They appear above whatever website I'm loading. The company has my email address if they need to notifiy me of anything, so this just seems like a giant middle finger - a way to remind me of their absolute control over my computer. It's totally creepy. Is there any way to block them?

Hello!

I have the problem that every of my most visited sites are loading normal fast except for YouTube.

YouTube needs about 2 to 3 seconds to load the site itself and the thumbnails like "lagging" pictures which are rendering real slow while my other most visited sites like Twitch, Reddit or Twitter are loading in about 1 second or less. (i have installed the "Page Load Time" addon to check that).

I have only installed uBlock and nothing else.

For some reason Montserrat fonts ignore font-weight for me on all websites. In happens on my main browser profile, with a new clean one with no add-ons and even in Tor Browser. Pictures 1 and 2 illustrate the problem. If i go into page inspector and replace "font-family: 'Montserrat', sans-serif;" with "font-family: 'Segoe UI';" the parameter works as expected and the alternative font is rendered properly.

Reinstalling fonts from fontsource.org didn't help.

OS: Windows 10 1607, FF - 120.0, issue was present for many versions before.

What is going on with the Bookmarks function continuously duplicating? I've used the add-in tool (Love It!), but my bookmarks keep duplicating! What is going on & are you going to fix it? I use Mozilla Firefox exclusively as I don't like or trust Microsoft Edge or Google Chrome. Would REALY like to get this problem corrected!
