Firefox freeware - The Latest User Reviews
Firefox freeware - The Latest Versions History
135.0.1 Feb 18, 2025 New Release New:
Firefox Translations now supports more languages than ever! Pages in Simplified Chinese, Japanese, and Korean can now be translated and Russian is now available as a target language for translating into.
The credit card autofill feature is now being gradually rolled out to all users globally.
AI Chatbot access is now being gradually rolled out to all users. To use this optional feature, choose AI Chatbot from the sidebar or from Firefox Labs. Then, complete the provider selection to see the chat interface become available on the sidebar.
Firefox now enforces certificate transparency, requiring web servers to provide sufficient proof that their certificates were publicly disclosed before they will be trusted. This only affects servers using certificates issued by a certificate authority in Mozilla's Root CA Program.
Additionally, the CRLite certificate revocation checking mechanism is also being gradually rolled out, substantially improving the performance of these checks.
Firefox now includes safeguards to prevent sites from abusing the history API by generating excessive history entries, which can make navigating with the back and forward buttons difficult by cluttering the history. This intervention ensures that such entries, unless interacted with by the user, are skipped when using the back and forward buttons.
Fixed:
Made improvements to the Translations feature which will reduce the likelihood that models will invent new, made-up words under some circumstances.
Various security fixes:
CVE-2025-1009: Use-after-free in XSLT
CVE-2025-1010: Use-after-free in Custom Highlight
CVE-2025-1018: Fullscreen notification is not displayed when fullscreen is re-requested
CVE-2025-1011: A bug in WebAssembly code generation could result in a crash
CVE-2025-1012: Use-after-free during concurrent delazification
CVE-2025-1019: Fullscreen notification not properly displayed
CVE-2025-1013: Potential opening of private browsing tabs in normal browsing windows
CVE-2025-1014: Ce
135.0 Feb 4, 2025 New Release New:
Hardware-accelerated playback of HEVC video content is now supported on macOS.
Hardware video decoding is now enabled for AMD GPUs on Linux.
Firefox will upgrade page loads to HTTPS and gracefully fall back to HTTP if that does not succeed. This behavior is known as HTTPS-First.
Having any issues with a website on Firefox for Android, yet the site seems to be working as expected on another browser? You can now let us know via the Web Compatibility Reporting Tool. To access it:
Open the Menu via the three-dot button while on a browser tab
Tap on “Report broken site”
Provide the form with as much information as possible, and you’ll directly help us detect, target, and fix the most impacted sites to make your browsing experience on Firefox smoother.
Fixed:
Firefox will now prefer PNG when copying images out of Firefox, allowing the preservation of transparency.
Changed:
Cookie Banner Handling by default in Private Browsing is now disabled. This was previously enabled only in Nightly and Beta. The feature can be enabled via the cookiebanners.service.mode and cookiebanners.service.mode.privateBrowsing prefs in about:config.
Developer:
The Developer Tools debugger editor now uses Codemirror 6 which improves performance.
Changes for add-on developers:
menus.update and menus.remove and the aliases contextMenus.update and contextMenus.remove now reject with an error when the menu item doesn't exist. Previously, the error was ignored and the promise fulfilled. (Firefox bug 1688743).
Web Platform:
Added support for the Intl.DurationFormat object, this enables language-sensitive duration formatting.
Added support for the CSS :open pseudo-class for styling elements that can be toggled “open” to display more content.
Added support for the :has-slotted pseudo-class, allowing authors to style the contents of a <slot> element when it is not empty or not using the default value.
The value plaintext-only can now be specified for the contenteditable attribute, maki
134.0.2 Jan 21, 2025 New Release Fixed:
Fixed UI hangs happening on YouTube and Google Docs in some situations (Bug 1939295).
Fixed a startup crash affecting some users upgrading from Firefox 133 (Bug 1941134).
Fixed an issue where search engines selection menus and context menus could be broken if a user had previously reverted to an earlier version (Bug 1940533).
