I often receive a 403 error when using Firefox Every time, before this happens, I get the unsafe website warning and then the 403 error when I continue anyway


I am using the latest version at the time of writing These errors only occur on my desktop PC I have tried to replicate this issue on both my phone (Android) and another laptop(Windows 11) but all the websites work normally on there.

I have tried the following, none of which have any effect:

  • Clearing cookies
  • using Troubleshoot mode
  • Restarting
  • Changing Useragent
  • Using "Forget about this site"

The following do fix the issue

  • Using a VPN
  • Using Google Chrome
  • Running Firefox in another profile

Going through the privacy and security tab and reseting all the settings sometimes works but only temporarily

The following are a few websites where the issue occurs

  1. https://kdice.com/
  2. https://latinitium.com/
  3. https://theysaidso.com/

I believe there is a memory leak (or memory growth) bug in Firefox 133.0 on Windows 10. It's site-specific. I am trying to login to my account at https://www.ssa.gov/, and it never actually gets to the login prompt. Using the Windows task manager, I can see the RAM usage keeps increasing, until it nears the 12 GB installed RAM capacity, at which time I kill the firefox process. I'd say this is a bug in ssa.gov, except the problem does not occur with the google chrome browser.

To provide further detail, I go to site https://www.ssa.gov/, and click on the "sign in" button. That takes me to the page where you choose the login method (id.me or login.gov) and I choose "id.me". It takes me to the "you are leaving Social Security's website " message, which is still on the ssa.gov website. At that point, firefox memory usage starts to increase, as shown in task manager. The browser never advances to the next page, but main memory usage keeps going up. This goes on for about 30 seconds before I have to kill the firefox process.

On some websites, namely GMX, the UK Guardian newspaper, Etsy and PatientAccess (there may be others), I cannot sign in using my login details. If I switch to Edge, using the same details, with the same laptop, my login works immediately. This also happens with a second laptop. I have tried clearing cache and cookies, but to no avail. Is there any setting I can change to allow me to sign in or do you have to fix your browser.

The version of Firefox is 133.0. Since installation, I have not changed any Firefox settings.

Best regards

Cannot Log on to Costco.com site after update to Firefox 133.0 in Win 10 pro on 2 computers. Both are up-to-date with latest software.

Entering valid account and password cause the Costco logon page to freeze for a minute then returns to log on screen with no messages about failure

Same behavior on two computers. Log on to Costco via Microsoft Edge works perfectly (on 2 computers before any trouble shooting ). Logon with Firefox 133.0 works with every other site that I regularly use - Samsclub, Amazon, Yahoo mail, my own mail servers, NYtimes, WashingtonPost, Google, Walmart, and others

Trouble Shooting Steps taken with no change in the problem logon to Costco + Cleaned cache / cookies + Disabled virus protections + Disabled firewall + Stopped all security services + Rebooted + In settings | Privacy & Security: Added Costco.com as Exception for Enhanced Tracking protection + In settings | Privacy & Security: Added Costco.com as Exception - Cookies and Site Date

Cannot open Analyst links on eTrade website. Looking at a particular stock and clicking on the Analysts link opens another window showing individual analysts and articles relating to their opinions of this stock. I cannot click on either the analyst's name nor the articles associated with their name. eTrade customer service says Firefox is not working well on their site. I tried Microsoft Edge and everything was fine. Is there some feature I should enable on Firefox or is this a shortcoming in Firefox?

I'm an author, publishing through KDP since 2022. As a UK resident, I publish initially on amazon.co.uk, after which Amazon sends the ebooks and print books to amazon.com and so forth. However, when I view the books on the US site, they are shown as 'currently unavailable.' This only happens in Firefox. I also use Chrome now and again, and it's fine there. The books clearly are available, because US readers buy them. But clearly I don't want to risk any US Firefox readers thinking they're unavailable, if they have the same problem that I'm having. I raised this with Amazon a while ago, but they said it was nothing to do with them, and must be an issue with my browser. I've recently published the third book in a series, and it's just the same. Any suggestions?

Yesterday, something went wrong in my Windows 11 desktop (I have a virus program installed). One of the casualties involved corrupting Firefox (it would not open). I reinstalled Firefox without removing the old version. Now I have a new installation but all my bookmarks and other data are missing. There is a folder on my desktop labelled as "Old Firefox data". It is possible to restore Firefox to a previous time (a day ago)? Thank you.
