Firefox 81 is a lean, mean browsing machine. As Quantum’s engine uses 30% less memory than Chrome browser, so your other programs can keep running at top speed. Now multi-tasking with multiple tabs just got easier. Because Firefox is a multi-process browser, your tabs stay fresh and quick to reload.

Firefox can now autofill credit cards
For Firefox users in the US and Canada, Mozilla can now autofill credit card information saved in the browser when shopping online.
When released, users can secure the passwords with your operating system login password. This option for Windows will be named 'Require Windows authentication to autofill, view, or edit stored credit cards.'
The new autofill feature is currently rolling out to users in the United States and Canada and may not be available to all users at this time.
New Alpenglow theme
Mozilla has added a new theme to Firefox 81 called AlpenGlow that provides a colorful appearance for the buttons, menus, and windows.
You can enable this theme by going into the Firefox Menu > Addons > Themes and then clicking on Enable under Alpenglow.
Control videos directly from your handset and keyboard
Firefox 81 now allows you to control videos via your headset controls or the keyboard, even if you are not using Firefox at the time or are in another tab.
This feature will be particularly useful when listening to a video or music in the background while performing other tasks.
Other bug fixes, improvements, and developer changes
New:
Firefox can now be set as the default system PDF viewer.
The name reported by accessibility tools for items in multi-tiered tree controls no longer incorrectly includes information from items at deeper levels, providing users with the correct level of content when using a screen reader.
Fixed:
We’ve fixed a bug for users of language packs where the default language was reset to English after Firefox updates.
Browser native HTML5 audio/video controls received several important accessibility fixes:
- Audio/video controls remain accessible to screen readers even when they are temporarily hidden visually.
- Audio/video elapsed and total time are now accessible to screen readers where they weren't previously.
- Various unlabelled controls are now labelled making them identifiable to screen readers.
- Screen readers no longer intrusively report progress information unless the user requests it.
Changed:
You will soon find Picture-in-Picture more easily on all the videos you watch with new iconography.
The bookmarks toolbar is now automatically revealed once bookmarks are imported into Firefox, making it easier to find your most important websites.
We have expanded our supported file types - .xml, .svg, and .webp - so files you’ve downloaded can be opened right in Firefox.

Developer:
TypeScript files are now properly identified in the Debugger panel and labeled with corresponding icons making it easier for you to find these files in the list.
HTTP JSON responses using XSSI prevention characters are properly parsed and JSON data presented in a form of an expandable tree. This allows easy inspection of such HTTP responses through traditional (expandable) tree UI.
It’s possible to pause on script first statement, which is useful e.g. in cases where developers want to debug side effects caused by script execution or timers.
The color vision deficiency simulation in the accessibility panel of Developer Tools is now more accurate. We removed protanomaly, deuteranomaly and tritanomaly and aded achromatopsia.
