Firefox 社群討論區

Yesterday Firefox started crashing tabs on load of a handful of websites that are seemingly random, like Twitter and a few shopping site tabs I had open. It wasn't after a system update or anything, it just started happening while Firefox was already open and those tabs had already been open and loaded. I've tried clearing my cache, site data, reinstalling Firefox, and it still does it. Upon further investigation, it seems to be something regarding libfontconfig, and mostly specific to users of openSUSE Tumbleweed.

Every time I open Firefox, the checkbox next to "Opening links in tabs" always disappears, even though I've checked it in previous sessions. How can I make it permanent?

I use Firefox on the Linux Mint operating system.

Is anyone looking into this? I found an article that told me to remove some cash files and it seemed to fix the issue but it continues to reoccur. Some apps such as MS360 Outlook seem to trigger it, but if it was truly just a corrupt cache issue then cleaning the cash/profile once should have fixed the issue. Instead its become a constant pain in the *** and I'm tempted to find another browser. Seems very recent as well as I've never had issues with firefox before.

Ubuntu 24 Mozilla Firefox 151.0.3

I signed in to https://accounts.firefox.com to sync Firefox on iPhone iOS 26 and got a sign in from an unexpected location.

Firefox iOS on iOS 18.7 Toronto, ON, Canada (estimated) Tuesday, Jun 9, 2026 11:43:14 AM (EDT)

I am in the NY,US and do not own any iOS 18.7 device.

Can you give me more information why the jump to a foreign device?

I play https://crazyshooters.com/ and https://crazyshooters2.com/ a lot! But the game became laggy since Firefox 148 and my ping spikes up. Other browsers play fine. I am on Linux Mint if that helps. (147 and below run fine)

bold text So I get the latest update to Firefox this morning, open a new tab, and all the tiles I had arraigned the way I wanted them no longer in that order, some are missing, some are duplicated 2-3 times. Why can't you guys quit with the window dressing BS and just make the browser stable. Why do we need to hunt for functions that were the same for many years that you decided needed to be changed? I remember when 'Settings' was on the new tab window instead of on the drop down menu in the tool bar.

My new tab tiles are a mess and I don't think I'll ever forgive you for that!

I am using Linux mint and have never encountered this problem before. It is not a login or password problem! I can't even open the site to get to that part! Connection timed out. Is there a simple fix like allowing AI enhancements? I found disabling them solved my shut down lag time and load time. I wonder what other sites won't work now.

Why is Firefox sending me email msg's saying to try the new firefox VPN when It doesn't seem to be available to me? It's not in the upper right corner as they state and it's not in the toolbar either which they also say it's suppose to be in!

I've file download feature in my web application. When polling of file percentages is complete i am sending file to the client (browser) But in fire fox it downloading an .html file instead of actual file. Whereas in chrome it working as expected.
