I have Firefox version 115.9.1-1.el9_3.x86_64 from RHEL 9 appstream repository. RHEL version is 9.3 (Plow). I have found that when I visit certain sites or pages the tab always crashes. Other sites work without problem. Issue happens without any addons, after cleaning history&cache, with new profiles and even after reinstall of Firefox. Examples of sites where the issue happens: - https://crypto.stackexchange.com/ (All addresses on the domain I have tried, while other Stack Exchange sites work fine.) - https://www.xxl.fi/ (All pages from frontpage dropdown menus crash but links from the frontpage to product pages work. Other language version of the same shop does not crash: https://www.xxl.se/) No errors are visible on the console when tab crashes. I have tried changing settings such as disabling hardware acceleration but it did not make any difference. How could I fix this problem or at least find more information about cause of it?
