Running Firefox 149.0.2 (64-bit) on MacBook Pro (16-inch, 2019) with Catalina (10.15.9).

I was in the process of updating a non-profit's website and had opened the html file on my computer. I noticed that the "y" (lower case) was missing from the days of the week. I checked the RUNNING website and saw the same thing. Checked he same website with Safari and the "y" suddenly appeared. Okay, so I then tried to add another "y" somewhere else on that page and ... nothing, so on a whim I added a "Y" to my Mac's file and guess what? It upper case Y displayed. Also noticed that on some web pages instead of showing me the characters in some words, it substitutes "ddddddd" for some words. What's up?

I’ve been noticing an issue with YTS-type sites on Firefox. The site either loads partially, the player doesn’t start, or it keeps buffering without playing anything.

What’s strange is that the exact same site works perfectly fine on Chrome and other Chromium-based browsers. Videos load instantly there, but on Firefox it either breaks or takes forever.

Things I’ve already tried: – Cleared cache and cookies – Disabled all extensions – Tried in private window – Checked network (no issues)

It feels like something related to Firefox compatibility with the video player or scripts used on these sites.

I also tested another version here which seems to work better on Firefox:

ytsmx https://ytsmx.stream/

Not sure what’s different (maybe a different player or encoding), but it loads without issues for me.

Has anyone else faced this or knows what might be causing it?

I've recently had a bit of a strange problem. I use on-line banking. When I wanted to print off the latest transactions, I proceeded as usual. Then, when I clicked 'print', the list of transactions was overwritten by an (apparent) HSBC document headed 'Reactivate your unclaimed account'. I could still print my transactions, but only at a much larger font size.

I phoned HSBC and could not get any help. It was suggested I took the printed pages into a local branch (fine suggestion with all the branches that have closed!). I did. I also took my pinpad into the bank so I could sign in on their computer. Surprise, surprise, the strange document didn't appear. The bank said that it must be my browser at fault and suggested I update the version. However, they were able to confirm that all my accounts were fault and trouble-free, with no suspicious activity.

This evening, I tried to do just that. Nowhere could I find any way of updating Firefox, so I deleted the entire app and reloaded it, using Edge. Once set up, I tried again. I still get the document. If I try using Edge, I don't get the document. Now I'm completely puzzled. What makes me even more suspicious is that this strange document shows all of my HSBC accounts, with the correct figures, but at the foot of the first page, in large letters, is the line "Are you sure you want to redirection?". Very odd language. At the head of the second page is another line "You will be token to a new page to login an view your credit card details". More odd language.

This problem has only occurred on Windows 11 - it never occurred when I was using Windows 10. My anti-virus software (Bitdefender) reports my system is clean. The problem also does not occur when using any other web browser.

My conclusion is that there is a problem between Firefox, Windows 11 and the HSBC online app.

Please can this be investigated. Many thanks, John Jesson

vary unhappy with the new update. never have had issues with fire fox like this. when going to zillow.com i get this message: upstream connect error or disconnect/reset before headers. reset reason: connection termination. I noticed this is only the fire fox browser having this issue. i have already disabled ad blocker and vpn reset fire fox lost all my tabs! reset the computer and nothing still, i get the same message. i have used fire fox since it was a thing and recommending it always. getting a different browser right now to do my house buying, i don't feel safe using fire fox for this adventure any longer. my apologies if this seems like an emotional decision but i see this in everything that gets to big they lose the plot its an infection that is embedded in everything now, windows, home and car pricing. major changes to os and how its used. company's hate there customers anymore and were noticing.

replaced a windows 10 laptop with a Linux Mint 22.3 laptop. Used Sync to transfer profile to the new laptop. Logged into the banking account (BECU.org) successfully. When trying to transfer money from checking to savings, the transaction failed with a statement that the date was invalid. The date was valid. A separate Linux Mint computer that never had a windows profile synced does not show this problem. Disabling all extensions did not fix this problem.

Hi,

I’m facing an issue with my website’s fine checking tool on Mozilla Firefox. My website is evgfinescheck.com , and the tool works fine in some browsers, but on Firefox it doesn’t load properly and sometimes shows an error.

I am already using the latest (updated) version of Firefox, so the issue is not due to an outdated browser. The tool either fails to fetch data or doesn’t respond as expected when users try to check fines.

I’ve checked basic things like internet connection and browser updates, but the problem still persists specifically on Firefox.

Can anyone guide me on:

What could be causing this compatibility issue? Are there any common JavaScript, API, or CORS-related problems specific to Firefox? How can I debug or fix this issue?

Any help would be appreciated. Thanks!

I am not able to copy and paste in Firefox while using Microsoft Office for the web. I can in the same documents using Chrome & Edge I have searched the web and tried every setting I could find but can still not use copy and paste

I'm stuck in an endless loop in Firefox for Linux (MX Linux) whenever Cloudflare is used as security.

"Performing security verification

This website uses a security service to protect against malicious bots. This page is displayed while the website verifies you are not a bot."

I click "verify you are human" and it just loops back to the very same challenge. It isn't broken in other web browsers like Vivaldi for Linux. Or Firefox in Windows 11. Just Firefox for Linux.

It has been this way for months.

I am using Firefox 149.02 (64-bit).

I access the website The Daily Beast (https://www.thedailybeast.com) and like to make Comments on some of their articles. Up until about 2 months ago everything was running smoothly. But now I am unable to use the Comment section. I get the following response from The Daily Beast...

"Oops, something went wrong :( We detected some connectivity issues therefore we’re unable to load the Conversation."

I do not have this problem when using either the Norton Private Browser or the DuckDuckGo Browser.

What's wrong?

I have CentOS Stream release 8 on my laptop and desktop, with firefox-115.11.0-1.el8.x86_64

If I connect to some sites, such as signin.costco.com, www.tesla.com/modely, www.airindia.com, www.meijer.com, I get errors such as You don't have permission to access "http://www.tesla.com/modely" on this server. Reference #18.71951eb8.1774502305.1a7c7680 https://errors.edgesuite.net/18.71951eb8.1774502305.1a7c7680 You don't have permission to access "http://www.airindia.com/" on this server. Reference #18.c50e2017.1774501671.2dadbdb4 https://errors.edgesuite.net/18.c50e2017.1774501671.2dadbdb4

The error appears invariant of my IP address (different IPv4 addresses after rebooting my router, or an IPv6 address via a proxy). I have Firefox 60.7.2esr and 78.5.0esr on an older machine. Those sometimes work to some of these sites, but don't support all the site functionality, e.g. I can't actually login to Costco. www.tesla.com/modely works in 78.5.0esr. The Firefox on my Android tablet works for tesla; I haven't checked all the other sites. In conversation with my ISP (Starlink) customer service AI, I have tried deleting cookies and disabling plugins (only H264 and Widevine) with no effect. It suggests there is a problem with Akamai fingerprinting the browser.

I get edgesuite errors using Lynx or elinkx or curl also

Ive tried other browsers like Chrome and Microsoft Edge and have no problem.

I do get a Message that states my Facebook account has been temporarily suspended and I have to shut my PC down to get out of this message which locks my screen!

Can you help or suggest anything.

Windows Defender shows NO issues.

Have 4 Gmail accounts... after repeated opening and closing one or two on my IMac, suddenly Gmail will not open login page. if I close Firefox and reopen it, all is fine. Tried several solutions including elimination of extensions, clearing cache, etc. all work for a few days then problem returns. Imac running Tahoe 26.4, Firefox auto update turned on. Wish to avoid creating separate Gmail pages.. I open Gmail from my bookmarks at top. TPlease try to keep it simple... I am an senior and OK with basic technology and wife (who has one of the Gmail accounts) is more limited in tech skills. Thanks

Suddenly—with no changes made in Firefox, no power failures, no anomalous occurrences, and with the latest version of Facebook—Facebook would not display reels when clicked on.

What came up was at first a briefly (maybe a second) displayed image, but rather than remaining, the image disappeared, leaving an all-black screen except for the usual icons normally there: in the upper left, the "X" for closing the window and the Facebook logo; in the upper right, the Facebook menu, messenger, notifications, and account icons; at the middle right, the up and down circled arrows (which function but which lead to more displays of only black as well); and lower-right center, with the vertical display of the thumbs-up emoji, comment, share, the three-dots more options icons.

Firefox 149.0.2 is installed on a Windows 11 computer less than a year old (which has displayed no anomalous or unusual behavior at all).

Clearing the Firefox cache and restarting Firefox have done no good. What is wrong here?

Thank you.

This is the message I get when trying to login to my Costco account: Application error: a client-side exception has occurred (see the browser console for more information).

Running on a Macbook with Tahoe OS. Certain websites will not display my responses to a checkmark box. Certain websites will not permit changing a checkbox default setting. Specific example: https://cards.barclaycardus.com/ has a checkbox with remember user name defaulted to a check. Attempts to click to remove the check do not work. Also, on certain websites when entering login information that is incorrect, the message indicating to correct the item(s) in red or highlighted does not display the incorrect items in a highlighted condition. In fact at the bottom of this page, the response box labeled Email me when someone answers the thread does not display a response when I click on it, even though the "response" is accepted.

Both amazon.ca and mec.ca emails do not show anything in the body of an e-mail. If I use a different browser (duckduckgo) everything is ok and I can read the whole e-mail. This only started with the Firefox version 149 but is continuing with version 149.0.2. My email is handled by yahoo.ca via rogers.com. So far I am seeing this only with the two companies listed here.

Any assistance is greatly appreciated.
