Firefox freezes when I try to sign into YouTube via Google. Becomes totally unresponsive and I have to close browser. It's the only site this happens on. I have cleared the cache and cookies, unchecked "Hardware Acceleration" and other recommendations from other posts. Please talk to me like I'm your Baby Boomer dad.

As per the topic, since the MacOS 26.0.1 update Firefox freezes after resuming from sleep. Specifically, tab selection, page refreshes or menu selections cannot occur. Keyboard command to quit does work and after a reload all tabs, windows and function is restored

None of my extensions have changed and for the first week or so after the initial MacOS 26 release this issue wasn't occurring. No other application or system changes have occurred since 26.0.1.

I use both Firefox and Google Chrome. My mouse works fine with Chrome but with Firefox there are frequent long delays (60-120 sec.) when moving from one web site to another. The mouse just freezes up and I have to struggle to close Firefox. No problem with the mouse with Chrome, but I prefer Firefox and its features. Any suggestions?

I opened Firefox on one of my computers as usual today but the whole performance changed. Used to go to my home tab and select various news sites to see what was happening. First, when I scroll down the bookmarks, I would hit the "news" and click on it so all the sub items would stay in the scroll, but instead of that, it wanted to open every item as a new tab. When I finally started opening the various news outlets, it opened them in new tabs, it had always opened in the same tab. Then, I couldn't close the various tabs it had opened. I would go to the tab and hit the "X" but it didn't close the tab. I had to use a drop down menu to close a tab. And when in a site, I used the scroll button on the mouse, instead of scrolling, it made the page larger or smaller instead of going up or down. What could make such a change in behavior? I opened up the 'settings' on it and looked at 'tabs' and they were the same as the ones that are on this computer that works as expected. Both computers have it set to open all previous windows and tabs. Both have the same settings for 'tabs' and 'browsing'. I don't get it. Both are version 143.0.3 (64-bit) I have Ubuntu OS.

Macbook Pro using Tahoe 26.0.1; desktop freezes when Firefox 140.3 is active. Desktop icons do not work. Firefox has to be shutdown for the desktop icons to work.

Hi,

When i switch between two tabs by clicking with my external mouse ( I am on one tab and then point and click on another) and then directly start to scroll the page zoom like it does when i hold ctrl+zoom. What causes this?

It does not do the same in other browsers or other apps. It does the same with external mouse and track pad.
