Obviously, this was a footgun for power users. Removed leftover Electrolysis controls that could sometimes trick parts of the browser into starting in a (very broken) multi-process mode due to some plumbing for it still being present, if users would try to force the issue with preferences. This potentially improves performance on some systems. Removed most of the last vestiges of the invasive Mozilla Telemetry code from the platform. Removed the non-standard ArchiveReader DOM API that was only ever a prototype implementation. Restored Mac OS X code and buildability in the platform. Removed all Google SafeBrowsing/URLClassifier service code. In other installations, you may find this licensing statement in the added license.txt file in the browser installation location. This improves compatibility with particularly old and/or archived websites.įixed several crashes and stability issues.Īdded a licensing screen to the Windows installer to clarify the browser's licensing. "Default browser" controls in preferences has been moved to "General".Īdded support for extended VPx codec strings in media delivery via MSE (RFC-6381).įixed a long-time regression where the browser would no longer honor old-style body and iframe body margins when indicated in the HTML tags directly instead of CSS. Improved display of cursive scripts (on Windows). Improved performance of parallel web workers in JavaScript. Improvements to CSS grid and flexbox rendering and display following spec changes and improving web compatibility. Implemented accepting unit-less values for rootMargin in Intersection observers for web compatibility, making it act more like CSS margin as one would expect. Implemented queueMicroTask() "pseudo-promise" callbacks. Implemented setBaseAndExtent for text selections. Implemented "optional chaining" (thanks, FranklinDM!). Through GPC, you indicate to websites that you do not want them to share or sell your data.

Implemented Global Privacy Control, taking the place of the unenforceable "DNT" (Do Not Track) signal. This will include the converted extensions for the few of you who are coming from recalled versions with -fxguid suffixes. Firefox extensions will be indicated with an orange dot in the Add-ons Manager in the browser. As always, please note that using extensions for an old version of a different browser is entirely at your own risk and we obviously cannot and will not provide much (if any) support for their use. We're once again accepting the installation of legacy Firefox extensions alongside our own Pale Moon exclusive extensions.
