Support,

After updating Firefox to 159.0, two Firefox windows were opened although only one was open at the time before Firefox was closed during a Windows 11 Update! The first window was expected but the one below at the URL was not:

This has happened before. Please address.

Firefox Color themes and vertical tabs—it’s enough to drive you crazy. For starters, most existing themes don’t support vertical tabs, so the tab bar just looks awful. And even after I went to the trouble of creating my own theme, a subsequent update left the sidebar without the actual background image—it’s just a plain, solid color now. What’s the point of putting in all that effort to make things look good, only for a single Firefox update to ruin everything? They’re pushing these vertical tabs on us, yet they haven’t even bothered to implement proper support for them. I really wish they’d finally address the vertical tabs and give them a decent, polished look; it’s not a bad feature, it’s just half-baked.

hello support team. after updating Firefox to latest 159.0 i faced crash error to opening some sites like www.digikala.com and so on. i want to ask you what should i do ? earlier i can use every sites and i uninstall completely and install again . nothing fix. so please help me to solve this issue. thanks

I have been using a financial website recently. I signed out and closed the web pages, Mozilla is set to always clear my History when closing my MacBook or my Windows 11 laptop. When I came back to either laptop some time later and go onto Mozilla and enter the webpage details, when I clicked on the login page my username and password are both in both of the relevant boxes. This should not be happening. Is it a setting I need to change or an issue with the Webpage? Just to confirm I deleted the user & password details from the login page & closed the login page. closed every other Mozilla webpage that was open. I quit Mozilla on the Macbook. Then I opened my Windows 11 laptop. Signed into Windows. Checked my Mozilla Account & cleared all history so there was no Nucleus webpages in history or anything else. My settings are set as shown in the attachments.

Then I found the login page and opened it.and There is were my user details & password. as shown also.

As I am trying to make my browsing faster by minimizing the use of the mouse, I have come across an issue: if I search among all tabs on Firefox for Mac, either by "shift + command + A" or by adding a percent sign to the address / search bar, selecting a tab that is within a collapsed tab group deleted the tab group in question in this keyboard-based manner of execution. This issue leads to the unnecessary need to recreate the tab group. I have verified the issue at least with a collapsed tab group containing a single tab.
