I'm not sure what is going on with Firefox the past 6 months but I'm constantly getting an access denied message like this..... "You don't have permission to access "http://www.sunglasshut.com/us" on this server. " However, when I use the Chrome Browser, the webpage loads instantly. I'm not a fan of Chrome and have supported Firefox for years. Why am I having issues with your browser?

I use Firefox 150.0. Flightradar24.com reports that my browser doesn't support WEbGL2. However it reports that Firefox supports WebGL2 since version 51.

Hello. I have a problem with the chat.deepseek.com website - every time I launch the browser, the language settings are reset from the system (or Russian) language set manually to English. Interestingly, this problem only occurs in Firefox, while other browsers work as expected. Additionally, the test profile created again also works properly. What I have done: 1. Reinstalled the browser, but it did not help 2. Deleted the folders responsible for Local Storage in the profile folder - didn't help 3. Cleared the cookies - helped until the first restart, then it was the same. History is enabled, and cookies are not cleared when the browser is closed. How can I solve this issue without deleting my profile? I don't want to lose my bookmarks, passwords, and website settings. Thank you in advance for your assistance.

For quite some time now, I am unable to sign in to my account at CanadianTire.Ca I get an error. The signon process goes to CustomerAuth.Triangle.Ca for the email and password input. When I click "Sign In" the return message is a yellow triangle followed by the word "undefined" (see attached).

All other browsers I have (Brave, Chrome and Edge) can sign in without issue.

I noticed that other users have the exact same issue. I have tried all solutions I could find. The browser is up to date as of today (150.0.2 64 bit). I tried troubleshoot mode, clearing the cache, deleting cookies, history .... On the web site I turned off ETP for CanadianTire.Ca and CustomerAuth.Triangle.Com.

I have used Firefox since it was v0.93.

I was getting popping in audio both in Smplayer & videos on other sites. I discovered the problem went away completely when I closed the X tab. When it was open, I noticed another glitch. I keep a small video windows to keep track of my sleep time. The elapsed time is displayed on them. Only when X was open it was throwing it off by about 3 seconds a minute. I closed it in Firefox & signed onto X on Chrome & all these problems went away. This is the only web site that has ever done anything like this. What is Firefox's problem with X?

I can't log into chase.com from Firefox, which I've been doing for years. I get an outage message. But down detector shows nothing. It went on for days so I tried Microsoft Edge with Bing and it works. Is there some Firefox setting I need to change?

i have tried to login via your mizilla browser, but not logged in. also when i am trying to browse linkedin and other websites, the web page not opening at first time, i am suffering in problem, but in my laptop i have other 3 browser, chrome, edge, brave, they work correctly and smoothly in the websites and all sites. only problem .

I can open gmail but it does not refresh. If I clear the cache it refreshes the first time only. Sometimes I get a message saying that my account is temporarily unavailable but I can access gmail with no problem on my iPhone, android tablet and with Google Chrome without any problems. Turning off the Advanced Tracking does not resolve the problem.

I've tried to access each of 3 new TP-Link EAP 770 access points' web interface using current version of Firefox on a Mac and a Windows 11 laptop and I believe there's some security setting blocking the access. Usually, I would receive the warning with an "Advanced" button to allow you to continue to the web interface, but now I only receive a "Looks like there's a Problem with the Site" with a "Try Again" button. I had an older Windows 10 laptop with an older version of Firefox that actually allowed me to access one of the access points, but after the laptop had been online for a few minutes (and updated the Firefox version) my access started to fail again. Any help is appreciated.

Thanks, JB

the website gem.cbc.ca no longer allows me to play a video in Firefox since Monday this week, but works as usual on Chrome. I have the same add-ons on both browsers Adblock+ and NoScript. Tried in a private window too and all the suggested Firefox settings, no go.

Also I was able to use primewire.mov to watch videos up until yesterday, but none of them will play for me today. Guess I should try Chrome for them too. I use a private window for those sites.

Windows 10PRO + ESU up to date for April Firefox 150.0.2 64bit No other changes except for an Adblock+ update a few days ago.

Hey everyone!

I just noticed that post FF's 150 update, I can no longer drag and drop folders into my DSM window. This has been a non issue for over 6 years and all of a sudden, poof. I did find that you can still to this on Safari, but long term, Mozilla and Synology need to address this. There's already a post on the Synology fourms about it and I've emailed their Support Team to see what they have to day. Posting this here in case anyone has found a workaround in the Config settings pane.

Thanks! --Brian

Hello! I can't login to my x.com account from Firefox 115.35.2esr on Windows 7 SP1. I'd was stay logged in many years before I accidentally clear my cookies. And now I can't login. It just reloaded input form when I type my login and press "Next"button. I tryed login from Private mode, I tryed to disable all addons. Nothing helped. But I still can login/logout from Firefox 140.10.2 on Windows 11.

In Firefox console I see

errors [ {…} ] 0 Object { code: 399, message: "Could not log you in now. Please try again later. g;177706962260066684:-1778241640627:geToqptptoIvemMOHotwS0TF:1" } code 399 message "Could not log you in now. Please try again later. g;177706962260066684:-1778241640627:geToqptptoIvemMOHotwS0TF:1"

and

Can anyone help me to fix it?

Zum Beispiel auf Websites von Swissmilk.ch und Landi.ch kann ich nicht scrollen. Auf Edge geht es aber problemlos ! Was muss ich bei Firefox ändern in den Einstellungen ? Lieben Dank für Hilfe.

Went to VRBO website to look at a reservation and the website, which showed me as signed in, showed nothing of the reservation. Said I had no reservation,, no history of saved searches. When I used Microsoft Edge, all my previous reservations, searches etc. were accessible. I cleared my Firefox cookies, etc. still had the same problem

It is impossible to access a certain website using Firefox mobile. Edge, Chrome and safari work fine. I tried to turn protection off but it makes no difference. Why is this happening? Site is www.hlc.bike a large b2b distributor in the cycling world.

Been like this ever since I installed FF mobile.

I've recently switched to Firefox but am finding some of the performance a bit cumbersome. I am continually being asked to hit "Send" ["To display this page, Firefox must send information ..."] when I am logging into my Outlook email or looking at my bank information. I'd rather not be "resending" these pages each time and am wondering if there is a setting.

On all other browsers the drop down menus still show after first use, except in Firefox - where after first use they disappear and you have to go back to Home to re-show them.

I have tried the suggestions give for configuring the site iin Elementor/Wordpress but none have solved the problem and I can only assume the answer lies in Firefox settings.

TIA

I couldn’t open our Dell OME (wouldn’t even bring up the login screen). I won’t go through everything I tried, but it seems to be the recent Firefox 150 update.

Same result on multiple PCs and in private mode, but worked in Edge or Chrome.

Hello,

These error messages can result from a compromised IP address which you can check here:

https://www.akamai.com/us/en/clientrep-lookup/ or here: https://dnschecker.org/ip-blacklist-checker.php?

However, this post is for the condition where these messages are received yet your IP address is clean.

I have two browsers installed Firefox and Chrome. Firefox has problems with an ever increasing number of websites (that are switching to Akamai Edgesuite) while Chrome marches on without issues.

I recently discovered the Browser User Agent identification string that is used by the server to determine what browser it is talking to. This is useful for serving content correctly to different types of devices like a phone or PC. You can find your Browser User Agent string here:

https://dnschecker.org/whats-my-ip-address.php

So thinking that this might be Firefox's problem I copied the string from my working Chrome installation and added it to Firefox. Unfortunately the issue continues.

So somehow Edgesuite is using something MORE than just the user agent string to kick Firefox to the curb. Does anyone have any clues as to what this might be and how to get Firefox in the good graces of Edgesuite?

Thanks, Steve
