Canadian provinces of BC, AB, and MB are all moving to new timezones on Nov 1, 2026.

Firefox still does not support any of the new timezones. This will break automatic timezone support for many applications, if not addressed immediately.

For the new timezone: Pacific Time (British Columbia): - Intl.DateTimeFormat().resolvedOptions().timeZone returns "Etc/GMT+8" instead of the expected value 'America/Vancouver' - new Date().getTimezoneOffset() returns 480 instead of the expected 420

There is only a few days left to address this issue. What is the rollout plan for the required updates?

Thanks.

Hello, I installed the Firefox 158.8 update on my iMac (macOS Sequoia 15.8.1) today. All websites are working as usual, except for Amazon Prime Video; it loads once and then freezes. I can't perform any actions on the page—everything remains unresponsive. I can't enter a different URL in the address bar or reload the page, either. The only thing I can do is close the page. I’ve cleared the cache and disabled ad blockers, but nothing changes. Strangely, this doesn't happen with Firefox on my MacBook. What could the problem be?

regards Burkhard

After a 10/20/26 update I cannot sign into my credit union through Firefox. I can sign in using Flex and other search engines. Why???

This morning I went to open gmail as usual with WIN 10 laptop using Firefox and I kept getting ...there is a problem. Didn't say WHAT THE PROBLEM WAS! Worked FINE yesterday????

amazon.com works. but amazon prime videos hangs up -- the first page htat comes up always has an add and a watch now button. instead of getting the arrow to watch, i get a rotating pizza and it never loads the video
