Shortly after upgrading FireFox, whenever I try to go to a website, like PayPal or my bank or anything else, I immediately get a large Ad/site for something frequently related somehow.

Like my bank I will get something suggesting an online bank, or ways to make banking easier. It will be a large window, covering my original window. I have to exit THAT site to get to the one I want.

It is a separate window, I cannot just X it out, I must shut down that window. Then the window that I actually want will be beneath it.

I can't figure out how to fix it.

I am using 147 ESR and when I go to permissions and block all cookies for the site plex.tv the cookies are not blocked. If I go to the URL field and select the lock, it shows "clear cookies and site data" which means the cookies have being accepted.

Why are the cookies accepted from the site when I have set cookies "blocked"

My Windows 11 computer crashed recently. Before restoring windows I was able to backup some data files. I thought that I had a Firefox backup, as I recorded a folder called “Old Firefox Data” It contained a Folder called “2eguguhi.default-release” of size 751 MB. It in turn contained 7,708 Files, & 2,269 Folders. When I re-started Firefox on my “fixed” Windows 11, It was a virgin with no History & no Bookmarks; my old configuration was lost. I tried to follow the advice Fro Mozilla Help But to no avail. It was not able to detect or recognise the Folder in “Old Firefox Data”

Am I Lost or can someone Help please.

在 Firefox 内部：

通过 JS 触发的新页面 通过 a.click 触发的新页面 甚至 rel=noopener 都会被标记为：

“related browsing context”

进而共享同一个进程，新页签因为内存占用过高，导致旧页签卡死。

通过设置

1. 添加 COOP 响应头 add_header Cross-Origin-Opener-Policy "same-origin" always;也无法解决

设置空白页再重定向也无法解决

I dislike having my search suggestions show in the address bar. I have cleared the box on the search settings box, however searches continue to show only in the address bar. If i go to the Google home page the searches show on a webpage Any help will be appreciated.

Hello,

As you can see always ask where to save is selected but whenever I download a PDF file it doesn't ask me and it just saves to downloads. How can I fix that?

In Firefox 148.0, I am encountering an issue related to input‑focus behavior on the default New Tab Page. I would like to confirm whether this behavior is now hardcoded or whether any configuration options remain available to modify it.

Issue description

When opening a new tab, Firefox displays a search box in the center of the page. In previous versions, this search box could function as a true input field. However, in Firefox 148.0, any attempt to type into this field results in the input focus being immediately transferred to the address bar (Awesome Bar). As a result, the central search box no longer accepts direct input and appears to function only as a visual entry point.

Configuration options already tested

Based on documentation and community discussions for earlier Firefox versions, I attempted to locate and modify the following about:config preferences:

• browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar
• browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar2

Neither preference exists in Firefox 148.0. I also reviewed other Activity Stream and URL bar–related preferences but did not find any that influence this focus‑handoff behavior.

Current observations

Testing suggests that Firefox 148.0 may have removed the internal toggles that previously controlled this behavior. The focus handoff from the New Tab Page search box to the address bar appears to be enforced at the application level, with no remaining user‑configurable switches exposed through about:config.

Questions for clarification

1. 1 Has the focus‑handoff mechanism for the New Tab Page been fully hardcoded in Firefox 148.0, making it no longer configurable through about:config?

1. 2 Is there a new or undocumented preference that restores the ability for the New Tab Page search box to receive input directly?

1. 3 Are there design documents, Bugzilla tickets, or release notes that describe the removal of the previous handoff preferences?

1. 4 If this behavior is now intentional and no longer user‑configurable, is using an extension (e.g., New Tab Override) the only remaining method to prevent focus from being redirected to the address bar?

Any technical insight or references from developers or community members would be greatly appreciated.

My browser recently updated and announced some stuff about using AI. I don't want it. I don't want to associate with AI. Is there a way to rollback my browser to a previous version?
