Firefox on Android freezes completely whenever I open multiple tabs.

Steps to reproduce:

Open the Firefox app on my phone.

Open a website in one tab.

Open a second or third tab and try to switch between them or browse.

Observed result:

The browser stops responding, freezes, and fails to load or switch tabs smoothly.

Expected result:

The browser should handle opening and switching between multiple tabs without freezing or crashing.

Can't get rid of this spam: ecare.all.r@emailff.att-mail.com Unfortunately I clicked on it and multiple spam sites came up. I've tried the spam filter and it doesn't work. Suggestions?

i have wasted hours trying to figure this out and to download the newest version IF it is compatible with my older Ipad Mini. All directions are bogus, as i do have any of the options which are mentioned.

What do I do about this warning I am receiving when I refresh my inbox? "The certificate for pop.windstream.net is not valid. Someone could be trying to impersonate the server and you should not continue"

   Unable to receive new messages on my Thunderbird inbox for this warning

Hi there, I have several email accounts I use Tbird to manage. One of those is a hotmail account. I have the settings setup correctly for IMAP synchronization. But, after the initial pull of messages, the connection to the server seems to fail? For example, I open tbird, it pulls in new messages, run filters, etc... If I come back and try to reply to a message, the outgoing server will timeout (if you test the outgoing server in settings, it connects. If you reply as soon as you open tbird, it will send a message from that outlook account). I believe this issue is more than just the outgoing server. For example, if I move an email to a different folder, it won't register the move until I reopen tbird? Similarly, sometimes if I try to open a message after tbird has been running for a while, the message will not open/fail to load.

These issues seem to be impacting only this outlook account. I'm really not sure where to go with troubleshooting and looking for guidance.

much thanks, Ryan

Currently I am trying to use the firefox built in VPN option. When I hit the turn on it turns on and goes green but I am unable to browse. I suspect this is due to the corporate firewall and content filters that are in place when I am in the office. The firewall team is looking for support as we are unable to find out what access is needed to be open for this service to work. What IP's does the service connect to for access? What ports are use for setting up that browser level VPN? Is their any application or urls that should be allowed? If documentation for what access is needed to be opened on a corporate firewall would be appreciated. We have searched extensively and cannot find the information other than this runs by Fastly. We cannot find ports/urls/ips that are needed.

Thanks Chris.

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

Firefox on Android freezes completely whenever I open multiple tabs.

Steps to reproduce:

Open the Firefox app on my phone.

Open a website in one tab.

Open a second or third tab and try to switch between them or browse.

Observed result:

The browser stops responding, freezes, and fails to load or switch tabs smoothly.

Expected result:

The browser should handle opening and switching between multiple tabs without freezing or crashing.
