I can't access the Firefox Add-ons website

I installed Ubuntu on my laptop a few days ago since then I'm unable to access the Firefox Add-ons website properly. The site takes a very long time to load and then I only get the html without the CSS. And even then if I try to install an add-on I get a connection error message.

Other than that, my internet is working perfectly fine. Chromium works and I can install extensions for it.

It seems that this url https://addons.mozilla.org/en-US/firefox/ is the only website I'm having trouble accessing right now.

It looks that you are missing some CSS files.

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

  • hold down the Shift key and left-click the Reload button
  • press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
  • press "Command + Shift + R" (Mac)

You can check the Web Console (Tools -> Web Developer) for error messages about blocked and unsafe and mixed content.

You can check the Network Monitor to see if content is blocked or otherwise fails to load.

Use "Ctrl+F5" or "Ctrl+Shift+R" to reload the page and bypass the cache to generate a fresh log.

I was just there, no problems.

Many site issues can be caused by corrupt cookies or cache.

  • Clear the Cache and
  • Remove Cookies

Warning ! ! This will log you out of sites you're logged in to. You may also lose any settings for that website.

Type about:preferences<enter> in the address bar.

  • Cookies; Select Privacy. Under History, select

Firefox will Use Custom Settings. Press the button on the right side called Show Cookies. Use the search bar to look for the site. Note; There may be more than one entry. Remove All of them.

  • Cache; Select Advanced > Network. Across from

Cached Web Content, Press Clear Now.

If there is still a problem, Start Firefox in Safe Mode {web link} A small dialog should appear. Click Start In Safe Mode (not Refresh). While you are in safe mode;

Type about:preferences#advanced<enter> in the address bar.

Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.

Then restart. Poke around safe websites. Are there any problems?

Thanks, but I did all of that and I still have the same problem on that one website. Here is a screenshot of what I get when I try to access it. It's what I get on both Firefox and Chromium.

Again, every other website on the internet is working just fine. It's only the mozilla add-ons website that's giving me trouble for some reason...

To add more info in case it's helpful, I installed the Ubuntu minimal ISO and LXDE desktop on top of it. I didn't install the ubuntu-restricted-extras package.

Ahh. Load the web page. Then, to reload the page bypassing the cache and force a fresh retrieval; Ctrl+Shift+R (Mac=Command+Shift+R)

The console showed a lot of errors that look like this for both css and js files,

Looks like it's the same issue as this question , but I don't have an antivirus and I'm not on Windows.
