Firefox Developer Edition (eo) 145.0 herunterladen

New
- Copy Link to Highlight allows users to share arbitrary sections of page with others by copying a link through the context menu with a given selection.
- Add, edit, and delete comments to make your own notes in PDFs (summaries, questions, tasks, etc.). The comment sidebar helps you scan all your comments and quickly jump to them, which is handy for long or heavily marked-up PDFs.

- Need a reminder of what tabs are in a group? Hover over the tab group name to get a preview of the tabs inside without opening it.
- Starting with Firefox 145, Nightly and Early-beta builds can now find previously visited pages using Semantic History Search, which lets users recall sites with natural-language and concept-based queries, all processed locally for privacy. (Learn more)
Changed
- Starting with Firefox 145, 32-bit Linux is no longer supported. We encourage users to install a 64-bit version of Firefox.
- Horizontal tabs are now slightly more round, following the look of vertical tabs. Buttons and text inputs, including the Address bar, have been updated as well for consistency.
- When a Firefox user has no extensions installed, and clicks the Extensions button on the toolbar, they will now see a message explaining how extensions can elevate their browsing experience with links to the Firefox add-ons store.
