Hi,
Firefox Dev Edition 90.0 b1 is HTTP 404
"The requested URL /portableapps/FirefoxPortableDeveloper/FirefoxPortableDeveloper_90.0_Beta_1_English.paf.exe was not found on this server."
New: MBox Viewer (Mar 22, 2026), Platform 30.3 (Mar 29, 2026)
1,400+ portable packages, 1.2 billion downloads
Our costs have risen a bunch. Please donate if you can!
As I was doing the cluster of releases today, I forgot to upload the Firefox Development Edition release to our own download servers. It's fixed now. Apologies for the inconvenience.
Sometimes, the impossible can become possible, if you're awesome!
No problem, that can happen. Thanks for the fix!
