Firefox 95.0.1 fixes Microsoft.com connection issues and other bugs

Mozilla plans to release a minor upgrade for the stable version of its web browser today. Firefox 95.0.1 is a bug fix release that will address several issues in the browser, including a connection issue to several Microsoft domains.

The connection issue was posted to Bugzilla, Mozilla's bug tracking site five days ago. The reporter received an error message, MOZILLA_PKIX_ERROR_OCSP_RESPONSE_FOR_CERT_MISSING, while trying to open a page on the Docs subdomain of the main Microsoft website.

The page, listing supported AMD processors by Windows 11, returned an error message and not the actual content. Firefox displays a Secure Connection Failed error page with the aforementioned error message.

Several users reported issues on other subdomains, including https://msdn.microsoft.com/, https://go.microsoft.com/ and https://support.microsoft.com/.

The issue appears to come and go sporadically, but the planned update of Firefox will resolve it for all stable users of the web browser.

Firefox 95.0.1 fixes three additional bugs. The first affects the Linux version of Firefox only. It addresses a crash in WebRender on "some Linux/X11" systems according to Mozilla. The Bugzilla report suggests that crashes "have increased a bit over the last month" and that the crash takes down the entire browser and not just a single process.

The next issue fixes a crash on Windows devices, specifically crashes when shutting down. The volume of crashes was exceptionally high according to Mozilla and made up about a quarter of the top 50 crash signatures reported to Mozilla during the time.

The volume jumped from 500-1000/day to multiple thousands per day around Oct 26th or so. We heard there was a Windows update around that time. However there are crashes on win7/8/10 and 11. Just the one most common signature for this issue has had 16000 crashes in the last 7 days, and about 1/4 of the top 50 crash signatures are from this issue, including #2.

The final issue is again limited to Firefox running on Linux devices. It fixes a website contrast issue that some users experienced when Dark Mode was enabled on the operating system level.

Firefox 95.0.1 will be released later today for all desktop operating systems that Mozilla supports. Users may open Menu > Help > About Firefox to run a manual check for updates once the update is released officially to update Firefox as soon as possible.
