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 have issues discerning where each of my desktop windows are. To help with this I use gtk.css styling to add a border on all of my desktop windows. For some reason, Firefox does not draw this border.

Is there any way to apply a border around the Firefox window?

I was able to get a border around the navigation area of the browser by adding a userChrome.css file but I don't see any way to do the same thing for the whole window.

Can this be done in userChrome.css? Using gtk.css styling? Any other setting or file?

I am running Firefox 155.0.1 on Ubuntu Linux 26.04.1 LTS using the Gnome 50 desktop.

Firefox on Windows 11. When I try to open Firefox I get a message that Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window. Close does nothing, Task manager - end process does not close. Stuck in a permanent loop here. Rhonda

Hi, I'm trying to pair my devices but it gets to the authenticator step but doesn't say which authenticator it needs. Is there another step I should be taking? Lou
