Firefox Support Forum

After a update my browser was running very slow, I'm not sure what I did but my whole browser, including history and bookmarks and add ons reverted back years. But I have a whole folder of Old Firefox Data which is from today.

How do I get this back on there and get everything back to normal?

I have Firefox as my browser on my laptop. Today I have been getting numerous pop-up messages from McAfee (which I do not have- I use a different web defense app) saying I need to renew my subscription or virus detected. Nothing I do gets rid of these pop-ups, which keep coming back (see example below) . How can I stop this from occurring? HELP!!

As of 21/11/2023, I can no longer use several chat services that had previously worked on Firefox, for example Santander bank and EDF. Plus, the POWR widget has stopped working on one of my favourite websites.... it used to pull in the charity's Facebook content but now all I see is the text and no imagery. All of these functionalities work fine in Google Chrome and Edge so what's wrong please? Thanks in advance UF https://www.aldingbournetrust.org/make.html

I can't seem to access one website that I used to visit daily: www.leftwinglock.com

I have no issue with any other site that I visit daily, and my co-workers are able to access that site so it is not down.

Is there something in my settings that is preventing me from viewing this site now?

Thanks.

When I try to login to the Tesco website I get this message: Access Denied You don't have permission to access "http://www.tesco.com/account/login/en-GB?" on this server.

Reference #18.26cc19b8.1700669440.3c27026b

I have cleared History plus cookiies and site data and cached web content

But I'm still unable yo login to this site.

I want to find to get rid of this or find the source of this so I can delete it.

In "about:policies" there are 2 Active Policies: "DisableTelemetry", and "DisableDefaultBrowserAgent" Also, in "about:policies" I'm not sure if it's related, but there is a long list of policies there too.

What can I do to prevent Firefox from keeping me out of certain websites and showing this error message: Firefox Can’t Open This Page

I just updated to Firefox 120, and tried the new GPC setting (Tell websites not to sell or share my data). I ran into a problem when I went to the Xfinity community forums (https://forums.xfinity.com/) . It causes a banner on top showing they recognize the setting. There is an "X" in the corner, and some text that says "Hide this banner", but they are not active. Plus, I cannot make a new post or do a general reply (that weird forum software has both local replies to a particular post and general replies to the general thread.)

Is this a bug in Firefox, or a bug in their forum software? I attached a picture of the message it gives.

Dear Mozilla/Firefox, in the past week or so Firefox is noticeably slower to load than Norton Secure or Google Chrome. Running from a shortcut or pasting the same link into the address bar, Firefox takes around 25 seconds to load where Norton is almost instant. There are features of Firefox that I prefer over other browsers so hope you can guide me how to fix this. Thank you,

Updated FF Tuesday evening and noticed first on Wednesday when unable to log in to my Tesco food website. Access not allowed from this server or some such. I tried to use the Tesco feedback form and then got alerts both from Avast (saying it was infected) followed by FF refusal to connect. I tried safe mode and removing and adding FF.exe to Avast without change. I reset FF without change. MS Edge allowed access to all these sites without a murmur.

Today i can get to Tesco main site but still not Feedback.

Also my local Synolgy NAS now has a warning that it is dangerous to access from FF. Nothing has been changed in its set up or security. I can and do override and access everything

Something in the Tuesday update has caused this clash. I did think at one point I also saw 120.0.1 being offered but that may have been my confusion.

Happy user of FF fro many years and do not want to change.

After years of shopping online with Tesco using Firefox suddenly I can no longer log in to Tesco.com. Just get 'Access Denied. You do not have permission to access------etc' I am sure that this happened after the last update of Firefox ! Tesco say its not their problem and the problem is with my Firefox browser. Please advise.

I am trying to log in to the Tesco retail site, and get this message: Access Denied You don't have permission to access "http://www.tesco.com/account/login/en-GB?" on this server. Reference #18.26cc19b8.1700734342.438f9dd8 This is a new problem - it was working fine a week ago, and I have made no intentional changes to the Firefox settings. I went to the Settings: Enhanced Tracking Protection, changed it to Standard, and added the Tesco site as an exception (this was following the advice on some other "Access Denied" posts) but it made no difference - I still can't log in. Everything works fine on Chrome, but I would prefer to keep using Firefox if possible. Any suggestions? Thanks

Trying to access my Tesco account but a page saying 'Access Denied on this server' appears. Can you rectify this? I urgently need to login to my Tesco Account.

PS. I have tried to solve the problem for 2 days but no success!

Hi. I've used Firefox as my main web browser on desktop computers for over a year now, and it's so far been the best web browser I've used.... except for one issue when it comes to major updates to the app.

I have Firefox set to open up on the tab/site I was using before I end a session and close the app. Whenever there is a new major version release, the update gets installed the next time the browser is launched before showing the browser window. But, when the window opens back up, I'm not sent back to the site/tab I was previously using. A new tab automatically opens up to a Mozilla page saying that Firefox has updated, along with a large promotion for another Mozilla service.

I then need to manually close this new tab, and find the tab I was previously using during the last session before the auto-update. This is mildly irritating since it takes some control away over how I want Firefox to start up, and the new update tabs seem to just be used as a way to promote other Mozilla products seeing how the actual "Firefox has updated" text is very small.

Is there a way to turn off these automatic new tabs after every major auto-update? Or if there isn't, could an option to change the way Firefox notifies about updates be added in a future version, such as using the OS' notification option instead of opening a new tab?

Currently running the latest version of Firefox on an iMac, with Mac OS Sonoma.

I have been playing gin rummy plus on my windows 10 pc in my firefox browser with no problem until a few minutes ago when I tried to sign in to the game again. I got this message: Your browser does not support WebGL. The game works fine on my laptop using the same browser. Can anyone tell me how to fix this problem?

I am in Europe. My Bank is in the U.S. I can no longer log on and access my account through this Mozilla Browser.

I continually receive this message:\Secure Connection Failed

"An error occurred during a connection to click-notification.capitalone.com.

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

This is my ticket (116230) from my initial request.

What can I do?

i have done everything i can to try and fix this issue but i cant seem to watch live stream on kick.com or twitch.tv

I can log into preply.com with Chrome and Edge, but always have problems with Firefox. I was able to log in once, but after that, I can't log back in.

Recently I had to reinstall Windows, and saw the opportunity to try getting this to work. Installed Firefox, but *before* I logged into Mozilla Sync (so I'm working with a 100% fresh installation with no history of having Firefox installed) I tried to log into preply.com. It worked. Then, I log myself out and try to log in again, and once more, I can't log back in. I'm attaching a screenshot of what I see when I try. Please note -- I have no bookmarks, no extensions, no addons, no browser history. Everything is tabula rasa.

I found this page:

https://support.mozilla.org/en-US/kb/fix-login-issues-on-websites-require-passwords

and followed it to the letter, meticulously, to no avail. I still can't log into the site with Firefox. Chrome and Edge, yes. Firefox no. I only have Edge because I can't uninstall it. I only have Chrome for situations like this, where Firefox doesn't work. Firefox is my main browser, and I really, really would like to figure out what's happening. I can't understand how this problem persists when the browser is freshly installed; I haven't imported one bit of data yet from my sync account.

Can someone more experienced than me please help?

Please help me restore my bookmarks and history - the update seems to have wiped everything clean. PLUS I have multiple Firefox icons appearing in my dock. MacBook Pro.
