I am a developer.I want to know the source code location in Firefox that reject tracker cookies and the code location for obtaining the tracking protection list after installation

Before update I have tree style tabs extension, that organized tabs and show it as list in left side of screen. And this was ideal setup for me. But new sidebar broke this. It Have rudimentary vertical tabs, that missed main feature from tree style tabs extension. But I cant hide this sidebar, because it also hide tree style tabs.

How i can return to my previous setup, where i only see tree style tabs extension ?

I am using Firefox 136.0 on a Macbook running Sonoma 14.5 & on a MacMini running Sequoia 15.3.1. When doing a search using the Google search engine in Firefox if I click on a result it no longer opens in a new tab, instead it just opens it in the same tab. If I right click on the result & select "Open in a new tab" it does. I experimented with using Yahoo search engine (which I hate) & new results still open in a new tab. I assume others are experiencing this problem when using Google search with Firefox since it is happening on both my Macbook & my MacMini. Anybody know if this a settings issue or is there a problem with the software?

/edit: moved thread from Firefox for iOS to Firefox section as you have macOS.

you are repeating old mistakes. You have become worse than Microsoft. Firefox is not remembering open tabs again. I have supported your Firefox until now but enough is enough.

现在的版本是136.0.1 之前鼠标悬停到标签页，会出现关闭的x按钮，这样无需切换标签页就可以关闭想要关闭的页面。 现在鼠标悬停标签页，关闭按钮也不会出现了，必须把这个标签页切换为当前页面才能关掉。 请问这个问题怎么解决？ （firefox的历次更新，似乎一直在去掉用户喜欢的，习惯的功能与特性，一直在自以为是的为用户制造麻烦，这个软件的衰落是必然的） The current version is 136.0.1 Previously hovering the mouse over a tab would bring up the close x button so that the page you wanted to close could be closed without switching tabs. Now when I hover over a tab, the close button doesn't appear either, and I have to switch this tab to the current page to close it. How to solve this problem? (The successive updates of firefox seem to have been removing the functions and features that users like and are used to, and have been making trouble for users, the decline of this software is inevitable.)

After a recent update, the 'Reopen Closed Tab' button has disappeared from my browser. Additionally, the drag-and-drop functionality to open hyperlinks in new tabs has stopped working. Is there a way to restore these features without reinstalling the browser?

Before I update, I often enter a url/paste a url in the current page and hit command + Enter and the page always open in a new tab.

Now I found that it sometimes open in a new tab, sometimes don't. Instead, if I do option+Enter it does open in a new tab every time.

This is a bit annoying because command + Enter has built into my muscle memory. Is this an expected behavior change and would I be able to configure it?

I'm a user of a site where I have ended up with a lot of accounts. I use the container extension to make it so I can have each account logged in simultaneously. However, since I added the accounts in a random order, the list is in nothing approaching alphabetical order. There are so many now it makes it hard to find them; plus I have containers I use for other sites. The only way I can find to reorder them is to remove and remake the containers in alphabetical order. I think it would be useful to make it so in the settings page there was the ability to grab a handle on the left-hand side of the container listing and drag it to be where you want it in the list.

help me restore all tabs if possible, there were more than 200 tabs i need to restore them. i tried to restore them through journal and other profiles but there were empty tabs there too.

I have literally over 200 tabs open at a time and recover them every time I reboot Firefox, but they are very disorganized. Is there a good way to organize them, for example, group related tabs together?

I've got a suggestion (for Firefox developers) for enabling the quick and easy saving, organizing, and restoring of tabs.

I've usually got maybe 200 or 300 tabs open --- all the time. And I always have Firefox restore them when I reboot. But they're very disorganized. Here's a suggestion for enabling the organizing of them more easily and quickly, using several features already available in Firefox.

1) use ctrl-shift-d to create a set of bookmarks with all of the tabs 2) export this set of bookmarks as HTML to a file 3) use your favorite text or HTML editor to organize the tabs 4) import this organized file into Bookmarks (with the same or a different name) 5) allow Firefox to open this new bookmark file as a new set of tabs (possibly replacing some tabs currently in use)

This seems to me a very logical, and not too difficult to implement, method of organizing a set of disorganized tabs, using a lot of Firefox infrastructure already in place. It would be a big help to me, and I suspect many others as well.

Firefox, as of less than an hour ago, is no longer saving tabs on close. This was also proceeded (After the first instance of this happening) by Firefox enabling the "Delete cookies and site data when Firefox is closed" setting (Privacy & Security -> Cookies and Site Data) all on its own (Also did this on my laptop a day or 2 ago). I have since uninstalled & reinstalled it almost 5x. Doesn't matter what settings I change. Doesn't matter if I'm logged in or not. It will not save them. Ever.

I have history set to not delete anything. I have the most obvious setting enabled (Startup -> Open previous windows and tabs). It still doesn't save them. Even after the reinstalls.

I have not changed my settings in over a month. The only difference between months ago, and now, is browser updates, and an extension I installed but didn't even have Enabled.

Including the issue with the browser not defaulting to the last folder that was downloaded into with the "Ask where to download" setting enabled. But that's an inconvenience. It's not making the browser virtually unusable like not having my tabs saved.

Hello, would like tabs titles to be styled like in attachment (screen is from Simple Tab Groups addon). Especially would like to decrease (vertical) gaps between titles. Is it possible by editing userChrome.css or something like this?

Hi,

I recently made an update and now got Firefox 136.

Now I´ve got the problem, that tabs where some sound is playing are getting resized.

There is no option for disable this and I haven´t found the specfic path for the about:config.

Any help would be welcome

I cannot consistently show an image preview when I hover over a tab, even though I have that function box checked in my general/settings page.
