Firefox Community Forum

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/
4. https://opensource.org/
5. httpe://obsidian.rocks/

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

Dear folks , Every time I click on Firefox for web search , Fragilepottery.com comes up , I simply cannot find a way to delete Fragilepottery , should I uninstall Firefox and install Firefox again ?

I have used Firefox for years. Suddenly, when I try to use it, it is replaced by yahoo.com. What is happening here?

I have tried doing the History > Forget about this site stuff and deleting cookies on individual sites. Still, I cannot get past the login page for a number of websites that are crucial to my operations. Like Elementor.com. when I need to connect to my account, I enter my username and password and it just stays frozen on the login screen. If I go the Edge, it works just fine, but FF keeps hanging on websites????

I am reaching out with a request regarding the regional availability of my add-on.

I would like to disable access to my add-on for users in Russia. Could you please guide me on how to restrict its availability in this specific region? If there are any settings in the Developer Hub or additional steps I need to take, I would appreciate detailed instructions.

When I try to log onto microsoft outlook I get the following message--- Your current User-Agent string appears to be from an automated process--- This has only started today so I can not log onto my account.

I'm using Floorp and its working perfectly aside from this one or two pixel thick line of white that completely borders the left side of my screen every time I open the Browser. Is there any way I can fix this?s

I use Firefox desktop for buying and selling on eBay. Lately when trying to buy items on eBay I can not view pictures on some items. The other problem is the buy this item button does not work. Some times this also happens when on mobile. Firefox is up to date. I believe this is all part of pushing everyone to use chrome or edge by websites. First started using Seamonkey and now Firefox. I prefer not to use either one ) chrome, edge) browsers. Why would eBay want to limit people to buy products on eBay? Any suggestions to fix this problem?

Hi, 2 days ago I switched from Chrome to Firefox. I buy a lot of stuff online from many shops, so I really need the autofill feature. I checked and it is available only in some locations, ex. France. Will it be available in Poland in about a month?

I recently got seriously worried when I became aware about the new AI firewalls these days, which monitors or inspect SSL encrypted packets, before the packets reach to the main website. These new AI firewall systems are installed in some countries by their governments to suppress free speech, or just spy on its people. These firewalls, as you may already know, uses DPI-SSL system, which decrypts packets traveling from user to the main website. To decrypt the HTTPS packets, these firewalls uses its own self signed CA certificates. So I am asking the firefox developers, that why you guys allow this privacy issue? Does the packets sent from a firefoxe browser to other websites are also decrypted, by these firewalls? If yes, then why you guys allow this? Firefox must ONLY allow a specific CA certificate made for firefox browser only. Firefox browser must never let other third party softwares, or any software, to decrypt its encrypted packets. This is a serious privacy issue. With these firewalls, they can see what users write in chats, or posts, they can see witch content we are watching on a website, they can see who we follow on social media platforms, they can see which content or posts we like and etc. Even passwords are not safe anymore, which e use for any website of platform. When passwords are not safe, so does our accounts of various websites. This is a serious privacy breach.

These firewalls is a weapon for those countries which want to suppress free speech or suppress opposition sides in a government or spy on its own people.

Please let me know if I am mistaken or my concerns are genuine.

When attempting to sign in using google on firefox, the page I've included as an image below pops up. In order to solve the issue, I've tried clearing cookies and browsing data, refreshed firefox, and uninstalled and then reinstalled firefox. This happens on all websites, and only when using firefox.

After last update Firefox will not open my Weebly website editor.

It keeps telling me that Firefox will not allow the page to be displayed if another site has embedded it. It advises me to open the link in a new window.

This does not work - I get the same error message. I need to be able to edit my website! Can anyone help, please?

I am writing to request assistance with recovering my deleted browsing history for my Firefox account. On June 18, 2024, I accidentally deleted my browsing history and I am hoping there is a way to restore it.
