Firefox 103 available for download, but promised swipe gesture is MIA

If you’re eager to get your hands on the latest version of the Mozilla Firefox web browser, you’ll be pleased to hear that Firefox 103 is now available on Mozilla FTP ahead of an official release later this week.

Mozilla Firefox 103 features another set of conservative changes aimed at improving the overall experience of using the browser rather than dramatically reinventing it.

This release was to add a big new feature: a horizontal two-finger swipe to back/forward between pages on Linux, with accompanying OSD animation/indication – like this demo gif:

It won’t be news if you read like I wrote about this change in June. Reader reaction to the (then beta) feature was positive; most welcome this long-requested feature that puts Firefox on par with other browsers available for the platform.

Despite the gesture tracking bug being marked as “fixed” for 103, the gesture does not work in the binary released so far. The idea is that the gesture should work “out of the box” when using the latest version of Firefox under Wayland (it will also work under X11 if the MOZ_USE_XINPUT2=1 environment variable is set).

Maybe it was sent to Firefox 104? You can keep on holding on alt and two-finger swipe left/right to move forward and backward, but the alt-less version is a much nicer implementation.

Elsewhere, Firefox 103 now highlights PDF form fields, handles high refresh rate (120Hz+) monitors better, and enables subtitles/captions in Picture-in-Picture used with Funimation, Dailymotion, Tubi, and a handful of other streaming video sites (adding the plethora that already support it).

Firefox 103 removes the configuration option to allow SHA-1 signatures in certificates. Mozilla claims that SHA-1 signatures in certificates are “no longer sufficiently secure” and are therefore no longer supported.

Elsewhere, Linux users benefit from a number of performance-related fixes to WebGL when running on NVIDIA binary drivers; VA-API runs on hybrid mesa drivers; and the “notify Mozilla of crash” checkbox is now checked by default on Linux (in line with the default setting on other systems).
