[harlan4096]

Mozilla plans to release Firefox 73.0.1 to the Stable channel later today. The new version is a bug fix release that fixes several issues in Firefox including crashes on some Linux and Windows machines.

The release is already available on third-party websites and Mozilla servers, but it is advised to wait with the upgrade until the official release announcements.

Firefox users may then select Menu > Help > About Firefox to check for the update to have it downloaded and installed.

Firefox 73.0.1

Firefox 73.0.1 fixes crashes in Windows and Linux instances of the web browser. Windows users started to report issues after upgrading to new versions of the Firefox web browser last month (in Nightly). Firefox would open but would not navigate to any URL or open any internal pages (about:config or about:addons).

Analysis showed that certain third-party applications, specifically programs by G Data and 0Patch, caused the issue on Windows systems Firefox was run on.

The engineer who has been assigned to fix the issue discovered that the programs were injecting dlls into the browser process which caused the issue.

Ok, I confirmed this issue with G DATA Internet Security 2020 for Windows. Looks like they inject C:\Program Files (x86)\Common Files\G Data\AVKProxy\ExploitProtection64.dll into the browser process, which modifies ntdll's export table. With the fix for bug 1608645, detouring ntdll's functions fail when modification is detected, resulting in no content processes. Let's find out how we can be compatible with the variation of export table tampering such as 0Patch and G Data..

The new Firefox version addresses another issue on Windows systems. The bug report on Bugzilla reveals that Firefox would not work anymore when the browser was launched in Windows 7 Compatibility Mode or when custom anti-exploit settings are used. The symptoms are identical to those of the issue mentioned above; Firefox becomes unable to load any URL.

Firefox 73.0.1 fixes crashes on Linux devices that occurred when playing encrypted content. A user reported the bug seven days ago after noticing that the attempt to play music on Tidal would throws a "plugin crashed" notification in Firefox.

The two remaining issues fix connection problems to the RBC bank website, which resulted in a blank page for some users who logged into the site, and Firefox unexpectedly exiting when leaving Print Preview mode.

Now You: did you run into any of these issues?
