Hi

For American Airlines, try https://www.americanairlines.com

For Lowes, try https://www.lowes.com

I hope that this helps.

Does not matter if I use http or https, the problem remains. The problem started concurrent with imposed update and is gradually getting more prevalent.

Problem resolved via:

Go to waterfox.net download/install the latest version waterfox.

sudo apt remove firefox

Works like firefox used to...

Do you have any add-ons installed in Firefox?

What level of Enhanced Tracking Protection do you have set?

Yes, DuckDuckGo Privacy Essentials. Worked before the upgrade, disabled DuckDuckGo, still did not work. Strict Tracking Protection, reset to default, still did not work after upgrade.

I've been having the same issue fairly regularly for a couple weeks. The request returns 403 and I'm served the same page as the OP with a reference to https://errors.edgesuite.net.

Domains where I've seen this today:

• https://www.rei.com
• https://www.mathworks.com

The home pages of websites have always loaded fine, but I encounter errors deeper in the site. On rei.com for example, I cannot load any product pages.

Here's an example URL that doesn't load for me: https://www.rei.com/product/127086/yeti-rambler-tumbler-with-magslider-lid-20-fl-oz

The only "fix" I've found is to open the page in responsive design mode with user-agent "Mozilla/5.0 (Android 15; Mobile; rv:143.0.1) Gecko/143.0.1 Firefox/143.0.1". This works the first time, sometimes, but reloading the page will bring the error back.

What doesn't seem to work:

• Clearing website data.
• Disabling all plugins.
• Adding exceptions to Enhanced Tracking Protection.
• Overriding the user-agent header to something known to work outside of FF.
• Fetching data from affected pages using cURL.

And of course, any website that gives me trouble will load just fine in Chrome ='(

It seems like these sites are using either a CDN or security service by Akamai and that that service has access filtering that is sensitive to Firefox users. So yes, this probably isn't a problem with Firefox. But individual Firefox users aren't having any luck getting Akamai to fix the problem.

FF 143.0.3 on Ubuntu 24.04.

I've started using Firefox on Ubuntu, coming from a Windows machine.

I'm having the same issue. Intermittently and quite often I cannot access certain sites (mouser.com, digikey.com). I'm also often forced to prove I'm human by holding down a button for 10-15 seconds, something I've never experienced running Firefox on Windows.

Just like the previous poster I get access denied on his posted link (I don't know where it's supposed to lead): https://www.rei.com/product/127086/yeti-rambler-tumbler-with-magslider-lid-20-fl-oz

This link here worked intermittently for me, but now refuses (access denied): https://community.element14.com/products/devtools/avnetboardscommunity/avnetboard-forums/f/auboard-15p

Clearing cookies and playing with the security settings do nothing. So I think the previous poster is right, that some common content delivery network doesn't like the Firefox+Ubuntu combination.

For now I will install Chrome, otherwise I cannot do my work.

FF 145.0 (snap for ubuntu canonical-002 - 1.0)

Update: there definitely seems to be a connection to Akamai causing this issue.

I filed an issue with mouser.com and this was apparently done through an "Akamai Customer Form", as I got the below reply from customer support, suggesting that Akamai doesn't like my Firefox browser. The mouser support page says "Firefox: Latest Non-ESR Version" is supported, not sure what that means.
