Firefox 150: Key New Features Explained

Mozilla's latest browser update, Firefox 150, brings a host of practical enhancements that make web browsing smoother and more efficient. From improved tab management to PDF tweaks and a long-awaited emoji picker for Linux users, this release focuses on productivity and user experience. Below, we break down the most notable additions in a Q&A format.

1. What is Split View and how has it been improved in Firefox 150?

Split View, first introduced in Firefox 149, lets you view two web pages side by side within a single tab—no more juggling separate windows. In Firefox 150, this feature gets a notable upgrade: you can now right-click any link and select Open Link in Split View to instantly open that link alongside the current page. Additionally, a new Reverse Tabs option appears in the context menu (accessible via the three-dot menu at the bottom of the focused split), allowing you to swap the left and right panels. These small but impactful changes make split browsing feel more intuitive and flexible for multitaskers.

2. How do you open a link in Split View in Firefox 150?

It's straightforward: simply right-click on any link on a web page and choose the new Open Link in Split View menu item. Firefox will immediately split the current tab and load the linked page in the adjacent panel. This eliminates the need to manually drag tabs or set up Split View from scratch, saving you time when you want to compare content, check references, or keep an eye on two pages at once.

3. What is the Reverse Tabs feature in Split View?

The Reverse Tabs option, found in the context menu (the three-dot menu) of a focused split, lets you swap the positions of the two web pages displayed in Split View. For example, if you have a news article on the left and a search results page on the right, clicking Reverse Tabs will move the article to the right and the search results to the left. This gives you quick control over which page you prioritize without needing to close and reopen splits, making it easier to compare information or adjust your workflow.

4. What PDF editing improvements does Firefox 150 include?

Firefox 150 adds several welcome PDF reader enhancements, most notably the ability to reorder pages. You can now drag and drop thumbnails in the sidebar to rearrange the sequence of a PDF document before printing or saving. Other PDF improvements include a more polished toolbar and better support for forms and annotations. While the exact list of changes is still being detailed, these updates make Firefox's built-in PDF tool more practical for basic document editing tasks.

5. Does Firefox 150 have a Linux emoji picker?

Yes! For the first time, Firefox 150 includes a native emoji picker for Linux users. Previously, Linux lacked a built-in way to browse and insert emojis into web forms, text fields, and messages within the browser. Now, you can access the picker by right-clicking in any text input area and selecting Emojis & Symbols (or using a keyboard shortcut). This brings Linux on par with Windows and macOS, making it easier to express yourself with emojis without relying on third-party tools.

6. What is multi-tab sharing in Firefox 150?

Firefox 150 introduces multi-tab sharing, a feature that lets you share multiple open tabs at once via the browser's share menu (available on supported platforms like macOS). Instead of sharing each tab individually, you can select several tabs from the tab list and send the URLs together to another app—perfect for collaborating on research, sending a list of articles to a colleague, or compiling resources. This enhancement streamlines workflows for users who frequently share collections of web pages.

7. How does Firefox 150 enhance multitasking overall?

With Split View improvements, the new emoji picker, PDF page reordering, and multi-tab sharing, Firefox 150 is clearly designed to boost productivity and reduce friction in daily browsing. The ability to open links directly into Split View and reverse tabs on the fly makes comparing content effortless. The emoji picker fills a long-standing gap for Linux users, while PDF enhancements and multi-tab sharing save time on document and link management. Together, these features create a more fluid, customized browsing experience that helps you stay organized and efficient.
