If there is anything I haven't tried yet, please let me know.

Hello, I have been unable to watch Netflix or any "other" video content using the Firefox browser for the past few weeks. I've been pulling my hair out while working through the help articles, alongside bouts of furious googling - all to no avail. On Netflix I am getting error code F7701- 1003. Netflix is telling me to use the latest version of Firefox, but I have been checking for new updates almost every day since I noticed this issue. My current version is 100.0 (64-bit) On other website I'm getting the error message "No compatible source was found for this media." I have followed all of the fixes listed on the following articles, but so far have not been able to fix my problem: [[Fix common audio and video issues]] [[Fix video and audio playback problems on Firefox for Windows]] If there is anything I haven't tried yet, please let me know.
