Comment on attachment 9139105 Bug 1495900 - Add fontconfig cache directories to content-process sandbox read paths. r=jld
### Beta/Release Uplift Approval Request * **User impact if declined**: Long pause (jank) in Firefox as a result of starting up chrome (or possibly other triggers) * **Is this code covered by automated tests?**: No * **Has the fix been verified in Nightly?**: Yes * **Needs manual test from QE?**: No * **If yes, steps to reproduce**: On affected system, launch chrome while firefox is running, observe whether firefox pauses for a noticeable period. (Dependent on fontconfig version and possibly other aspects of system configuration.) * **List of other uplifts needed**: None * **Risk to taking this patch**: Low * **Why is the change risky/not risky? (and alternatives if risky)**: Trivial, just whitelisting directory where fontconfig caches may be stored * **String changes made/needed**: -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1870827 Title: Firefox hangs after simultaneously opening Chrome/Electron-based applications Status in Mozilla Firefox: Fix Released Status in firefox package in Ubuntu: Confirmed Bug description: When opening Chrome/Electron-based applications while Firefox is open, Firefox' tab contents stop responding, and it becomes necessary to close Firefox and reopen it. This includes: - VSCode: https://code.visualstudio.com/download - Atom: https://atom.io - Chromium browser Here's a link to a screenshot that shows Firefox with a "loading" waiting icon on the center of the tab (applies to any other open tab) https://imgur.com/PHHr3zt.png This has been happening since Ubuntu 14.04, but my previous report was quickly dismissed. I've done fresh installs for 14.04, 16.04 and 18.04, and the problem persists ever since. OS: Ubuntu Release: 18.04 LTS (other 18.04-based distros such as elementaryOS exhibit the same behavior) Firefox: 74.0.1, 64-bit (although the problem happens since 32-bit 60.x or even earlier) Current Hardware: Lenovo ThinkPad T410s: Intel i5 540M processor, NVidia NVS3100M graphics, 8Gb RAM, 480Gb SSD # Expected behavior While Firefox is open, any Chrome/Electron-based application that is opened works without affecting Firefox, either loaded before or after it. # Observed behavior While Firefox is open, any Chrome/Electron-based application that is opened hangs Firefox, as observed according to the screenshot link provided above. Note that if Firefox is loaded *after* Chrome/Electron-based apps, the above described behavior isn't exhibited.
