When opening Firefox, the screen turns white before page opens! There is a version that was updated for this issue however,at that time I did not have this issue! After downloading the newer version, I now have this white light issue! I like to mention, my computer never crashed! I believe (134.0.3), was the update that was a fix for the White Screen problem. And, I am using ver-139.0.4 (64 bit) (win. 10-64 bit) I appreciate any help with this issue! Thank you!!! geo (7/6/2025)

When debug threejs in firefox(windows, not verified in linux), after breakpoint is hit the other web page is un-operational, you can not click the url on other webpage.

Since the last update Firefox sends the processor load through the roof. Both on desktop and on Android. For the first time since like version 7 I'm a bit disappointed.

What's up with this?

I have been using Firefox for awhile now and something weird is happening. I can't close tabs by clicking on the 'x' on the tab. I also can't use the back arrow and the refresh button. I can right click and close tabs that way and the bookmark bar works. The problem seems confined to the top two bars. Thank you.

When I start Firefox without any internet, i.e. Airplane mode, the browser starts up pretty quickly. However when I connect to internet, either via WiFi or LAN, the startup time increases dramatically. This means that Firefox is connecting to the internet, waiting for some server to respond and then finish the launching of the browser. I have been able to figure out that Firefox connects to the following URLs when it launches.

1. cdn.statically.io
2. img-getpocket.cdn.mozilla.net
3. ublockorigin.github.io
4. aus5.mozilla.org
5. content-signature-2.cdn.mozilla.net

Please note that this is not the complete list, it is just what I have been able to figure out. There might be other URLs that Firefox connects too, which I am not aware off.

So my questions are as follows 1) How do I come to know all the URLs Firefox is connecting too, when it launches? 2) How can I check how much time does the server take to respond back to Firefox? 3) Is there a way that to stop the connection between these servers and Firefox? For example, pockets is getting shut down and I do not use pockets. So I maybe the connection to img-getpocket.cdn.mozilla.net can be terminated or stopped. OR maybe the connection to content-signature-2.cdn.mozilla.net can be asychronous and need not hold up the browser loading and so on
