I've been having issues with Cross-Origin Request Blocked errors for a while now. I'm on Windows 11. I first noticed this issue when visiting YouTube. I would go to play a video and any video I tried to play would just load forever and never play. Then I noticed I was having the same issue on Facebook. The page would load but then a majority of the images wouldn't. I can use YouTube and Facebook just fine on Chrome. The reason for the error shows as "CORS request did not succeed". Initially I tried uninstalling all of my extensions. Then I completely uninstalled Firefox using Total Uninstall (for good measure). Nothing has worked. I'm not sure what changed that would cause these errors. Could this be a network issue? I've been having issues with certain sites on my Macbook Air as well (Chrome and Safari) but I thought maybe that was because it's pretty old and not supported by apple anymore.

When I click submit on a form and switch tabs before it completes processing and return to the tab after the page is not refreshed with the new page returned from the server. However, the action has completed on the server. This only started happening in the last couple of weeks. Note: if I stay on the tab without switching it is fine.

Firefox has an excellent built-in screenshot feature that allows users to take full page screenshots of web pages. I am a Mac user. I use Sugarsync cloud service to keep my Mac Studio desktop (OS 12.6.3 Monterey) and Macbook Air (OS 13.3 Ventura) laptop in sync. I am running Firefox 133.0.

I have noticed that Firefox .png screenshots have not been uploading properly to Sugarsync for the last 6 months or so. In Finder a green tick appears which indicates that a file has been properly uploaded to SugarSync but when I go to the Sugarsync app I can see the following error message for such files "Waiting on upload from Mac Studio". This means that screenshots I take on my desktop do not go across to my laptop and vice versa.

I spoke to the very helpful tech support (Luis M, senior tech support) at Sugarsync today and he and his colleague were able to figure out that the problem has to do with the attributes of the saved .png files.

I will outline the issue in detail:

On a Mac you can examine the attributes of a file by doing the following: - right click on the folder in which your file is located and click "new terminal at folder". This opens a new terminal window - type the following: xattr -l and then drag and drop the file name from finder next to the "xattr -l" and then insert a space, a dot and a forward slash and press enter, i.e. myusername@NameOfMyComputer Foldername % xattr -l full path and file name ./

For example if I take a screenshot of the following URL: https://www.mlb.com/ and I save the screenshot in a folder I have named "Firefox Screenshots" it saves as as "Screenshot 2024-12-07 at 14-48-02 MLB.com The Official Site of Major League Baseball" on my computer. I can examine it's attributes in terminal using the steps outlined above:

myusername@NameOfMyComputer Firefox Screenshots % xattr -l /Users/myusername/Firefox\ Screenshots/Screenshot\ 2024-12-07\ at\ 14-46-28\ The\ New\ York\ Times\ -\ Breaking\ News\ US\ News\ World\ News\ and\ Videos.png ./

When I click enter it generates a massive amount of information that looks like this: /Users/myusername/Firefox Screenshots/Screenshot 2024-12-07 at 14-46-28 The New York Times - Breaking News US News World News and Videos.png: com.apple.metadata:kMDItemWhereFroms: bplist00?_ /Users/myusername/Firefox Screenshots/Screenshot 2024-12-07 at 14-46-28 The New York Times - Breaking News US News World News and Videos.png: com.apple.quarantine: 0081;6753c517;Firefox;0F67116D-C970-45CB-A578-65EAFC93F6DD myusername@NameOfMyComputer Firefox Screenshots % xattr -l /Users/myusername/Firefox\ Screenshots/Screenshot\ 2024-12-07\ at\ 14-48-02\ MLB.com\ The\ Official\ Site\ of\ Major\ League\ Baseball.png ./ /Users/myusername/Firefox Screenshots/Screenshot 2024-12-07 at 14-48-02 MLB.com The Official Site of Major League Baseball.png: com.apple.metadata:kMDItemWhereFroms: bplist00?_Q?^data:image/png;base64,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 etc etc etc

The total output is over 19 million characters long due to the long alphabet soup that is generated. And this why Sugarsync is unable to properly upload the file.

You can retrospectively fix folders that contain .png files that will not properly upload to Sugarsync by right clicking on a folder, selecting "new terminal at folder" and typing the following: xattr -d -r com.apple.metadata:kMDItemWhereFroms ./

This fixes the attributes and the .png screenshots files immediately start to upload to Sugarsync. When you examine the attributes of the file again it shows the following:

/Users/myusername/Firefox Screenshots/Screenshot 2024-12-07 at 14-48-02 MLB.com The Official Site of Major League Baseball.png: com.apple.quarantine: 0081;6753c575;Firefox;D5072DFA-9EE8-4EF1-9658-86263462F1CD.

Could the Firefox developers please look at this issue and liaise with Sugarsync?

Many thanks in advance.

I have a typical search bar at the top of the browser window. Recently, as soon as I begin to type a search, the bar expands to cover the whole top of the browser window. How do I stop this from happening? It's unnecessary and irritating. Firefox 133.0, Win 11

Is this something to be concerned about with future sites, or is this an unfortunate, isolated incident? One of my local utility companies is not going to be supporting the use of Firefox on their website any longer. Has anyone else seen anything like this on other sites, or has this been brought up elsewhere? Frankly I find it outrageous and is forcing me and others to use Chromium based browsers (aside from Safari which I don't use).

• I emailed the company asking for an explanation, and I'm awaiting a reply.

I would share the URL for others to email and help press the company on the issue, but wasn't sure of the guidelines of the forum or if that was appropriate. I'm just irritated and venting sorry =/

I would like to take a screenshot of my expanded emails on protonmail.com - but it is not working when when I click "full page" option. Is this possible? I don't want to take screenshots manually by scrolling down the window...

I recently started having a problem with my banking website. Before I could investigate or report it, Mozilla released a bug fix 1923500 "Firefox 131 Enhanced Tracking Protection major breakage of multiple banks Bill Pay services" I have updated to Firefox 131 however, there may still be a problem, however before I report it I'd like to verify if it's simply that their link is broken. Let me explain: On my bank's website there is "Payment Inquiry" link with this link "https://paybills.MyBankName.com/imm/Auth/SLO/4661?ReturnUrl="

What happens is that it sends me back to the login screen, I navigate to the Payment Inquiry again, click the link... rinse and repeat... in an endless loop. I suspect that the URL is malformed because there is nothing following the "=" sign. I would expect something to follow the equal sign. Is this indeed a bad URL? Should I pursue with my bank? I only ask because is seemed more than a coincidence that this occurred near the same time as bug fix 1923500.

I've just updated from Firefox 101.0.1 to Firefox ESR 115.18.0 (I'm still using Windows 7, so can't get a more recent release). I have a program which reads a cURL command from the clipboard then runs cURL repeatedly with slightly modified versions of the command. The command is read from the clipboard rather than pasted into the command prompt window because it may be more than 4096 characters. This no longer works with the updated version of Firefox. Comparing the cURL commands from the two versions of Firefox showed lots of "^" characters had been added. For example "120Months|Yield|RiskScore" had become "120Months^|Yield^|RiskScore". When I edited the cURL command to remove the "^" characters, everything worked like it had before the Firefox update. I suspect this is related to the changes introduced by Bug 1777800. I would like to know whether the problem can be reproduced using up-to-date versions of Firefox and Windows. Starting with web page https://www.trustnet.com/fund/price-performance/t/investment-trusts?norisk=true&PageSize=25 use the network monitor to capture the result of moving to the next page of data, Copy as cURL (Windows) and use the result. Do you get a response containing the data for the next 25 funds or a very small file containing an error message?

'Another' Issue With Firefox:

On my desktop, I view Facebook via the Firefox browser. When viewing posts from other people, the date/time stamp is no longer visible.

Instead, it shows a random series of numbers and digits. However, 'hovering' over it displays the date and time.

Refreshing the page does not work. The issue also occurs on Opera.

'Again,' am I missing an 'obvious' detail here?

Hi, there are bugs with text selection when using touch. The video below explains. But simply selecting text is really buggy and the bugs happen randomly, long pressing on text sometimes selects text sometimes not, sometimes opens context menus sometimes not. The preferred behavior is to select text and open the context menu at the same time.

Hello, earlier in the day I pressed a keyboard shortcut on accident when picking up my keyboard and has changed google results quite dramatically. I grabbed my keyboard and had a menu pop up on the left side and after i closed it noticed my google results had a scroll bar now. The results page only presents itself on the left half of the screen and a scroll bar has appeared on both the right side, cutting off text, and bottom of the page. These scroll bars only move a tiny bit and are quite unnecessary, but makes scrolling a pain as I have to be sure I am outside the new scroll bar area as they take precedent from the main scroll bar. I have googled Firefox's keyboard shortcuts and haven't found the one i need to fix this. Before I'm asked, no I do not have crazy zoom on and no zooming in does not fix this problem.

I'm on Developer Edition of Firefox. In previous versions of Firefox (Probably 132), I could share the window just fine, but since an update to either Teams or Firefox, it just results in a blank screen for viewers.

Unable to view YouTube comments using Firefox on android. I can view the comments on Opera, duckgo and chrome.

This problem started about four days ago. Comments show on the short videos but not the regular videos. When I tap on "comments" the resulting page/frame is empty.

Latest Version Private Browsing Mode

Hello.

'Autoplay->Block Video and Audio' selected.

2 websites listed, which I did not place there, 'Allow Audio and Video' selected:

1. about:welcome 2. aboutwelcomeprivate welcome

'Removing' them causes them to be automatically 're-appear.'

Suggestion: about:config, .isolateBy.privateBrowsing,' and change 'True' to False.

Changing the 'above value' does not remove the 2 'allowed' websites nor does it stop A and V from playing automatically.

Not possible to Block all Video and Audio Automatically 'or' am I missing an 'obvious' solution?

FF v131.0.3

Just started seeing this issue when selecting a news item video in emails from Haystack News Midweek Report <founders@haystack.tv>.

Normally, selecting an item in the email message would open the subject story video in a new tab where I can 'play' the video. Now I get the new tab opened with a blank (white) screen, but noticed something strange in the URL. Here's an example: https://notifications.haystack.tv/CL0/https://www.haystack.tv/v/economy-grew-robust-pace-quarter.

https://notifications.haystack.tv/CL0/ is leading the normal URL address. If I take this part out the video loads and plays as expected.

Anyone have an idea what caused this? Thx.
