Browser / Version: Firefox 106.0
Operating System: Windows 10
Tested Another Browser: Yes Chrome

Problem type: Site is not usable
Description: Page not loading correctly
Steps to Reproduce:
Since the 106 version, all the google-related websites (google.com, youtube, google-translate, google-analytics) have difficulties to load on firefox. Sometimes some are working and other not, most of the time a part of them are inaccessible for hours (page loading indefinitely). It happens only since this last version, and it doesn't happen on Chrome or Edge (on which everything works fine). Every usual solution (new profile, deactivate extension, clearing cache, restart...) didn't work. The only thing which did work was to deactivate the HTTPS protection on Avast antivirus (after that, all works fine again). Cutting this Avast HTTPS agent also did the trick for another user (on french mozilla forum) which had the same problem. Problem is also reported there: https://www.reddit.com/r/firefox/comments/ybvfqf/i_have_trouble_loading_all_webpages_that_are/
