Firefox Community Forum

Getting around 20ms for DNS lookups so thats not the issue. Why do I see Error Code: NS_ERROR_OFFLINE maybe once every several days when this Firefox has never been in offline mode and never will be? Env is MacOS 26.5.2 with current Firefox installed.

Have cleared browser cashe and rebooted, all to no effect,so how can I complete an upload of requested information if I can't get through and keep getting the 403 error message?

I must find a way to disallow this undesirable and very annoying feature. It is always there even after removing all the protection I could. Please help

I have cleared data and cache and the time is correct but I get, Error Code: PR_CONNECT_RESET_ERROR, and will not log in. I have also done a cold, and hot restarts.

I keep getting a connection failed warning and a new Key that blocks connection appeared after the last Firefox update, which I cannot /have not figured out how to remove or cancel

Hello,

I would like to report an issue with the Firefox Add-ons Store.

Recently, I suddenly encountered an "HTTP 406 Not Acceptable" error when trying to access the Firefox Add-ons Store. The store is completely unusable for me right now.

Here are the specific details:

Issue description: I have tried accessing the store on every network available to me, including mobile data, my office wired network, and my home wired network. Unfortunately, I get the same 406 error on all of them.

Timeline and context: Everything was working perfectly fine last week. I was able to search for and install a Markdown add-on without any issues. However, starting this week, it suddenly started returning the 406 error.

Additional troubleshooting:

I am not using a VPN or proxy. However, if I enable a proxy, the Add-ons Store works normally.

There is no antivirus software or firewall blocking Firefox's network requests.

Other websites load normally. Even mozilla.org works fine, but addons.mozilla.org does not.

I have also tried changing to other DNS resolvers, but that did not help.

Could you please help me understand why this is happening and how I can resolve it?

Thank you!

I keep getting these error messages on some websites I frequently visited in the past. I didn't change anything in Firefox. I can go to Costco's home page but in searching or clicking on an item I get this message "Access Denied You don't have permission to access "http://www.costco.com/laptops.html" on this server.
