This issue is new and I have never experienced it before. Upon trying to open anything in a new tab, firefox gets completely stuck loading the site, and when refreshed, does the tab becomes "dead" and nothing can be entered or clicked on, even after minutes. I know it is not my internet connection, as other browsers such as opera and edge work, as well as my ability to download games from steam, and firefox is also up to date as shown by the settings page, but firefox does not allow anything to be opened or viewed other than the settings page, which I used to navigate to the support page. I could not even use "continue with google" as a method of signing in and needed to manually enter everything.
