Improve Firefox Startup Time

Are you tired of waiting for your Firefox browser to start up every time? Look no further! There are several tweaks and optimizations that can be made to improve the startup time of your Firefox browser.

One of the most significant improvements can be achieved by using media-libs/openh264 for H264 support instead of downloading a binary blob from Mozilla at runtime. This will eliminate the need for extra downloads and reduce the overall startup time.

Another optimization is to enable profile-guided optimization for faster binaries. While this option will double the compile time, it can significantly improve the performance of your Firefox browser.

Additionally, you can enable sound server support via media-libs/libpulse (PulseAudio or Pipewire, or apulse if installed) and disable support for remote desktop and screen cast using PipeWire. This will help to optimize the startup time of your Firefox browser.

To get meaningful backtraces, it's recommended to enable EME (DRM plugin) capability at build time. You can also allow Gecko Media Plugins (binary blobs) to be automatically downloaded and kept up-to-date in user profiles.

Furthermore, you can activate default security enhancements for the toolchain (gcc, glibc, binutils), force-enable hardware-accelerated rendering (Mozilla bug 594876), and enable support for the JACK Audio Connection Kit.

If you're using a Unix-based system, you can also enable unified build - combines source files to speed up the build process, but requires more memory.

In terms of known issues, some users have reported that Windows decorations are missing in Fluxbox since FF-91.3.0. Additionally, some users have experienced dbus support issues for applications like gpsd and gnomemeeting.

If you're experiencing issues with touchpad scrolling, you may want to adjust the scrolling speed settings or try using a different pointing device. Some users have also reported issues with screen tearing or stuttering smooth scrolling on certain systems.

In terms of sound-related issues, some users have experienced problems with PipeWire or JACK Audio Connection Kit not working properly.

Finally, if you're experiencing hardware acceleration issues or green artifacts on video playback, it may be due to a conflict with your system's graphics drivers or hardware configuration.

By implementing these optimizations and tweaks, you can significantly improve the startup time of your Firefox browser and enhance overall performance.
