I have the same issue as other users. All my tabs in Firefox are loading on start-up. I use the extension because Google does not load when I am connected with the desktop app only. Somehow with this plugin I bypass this issue.

I have tried all the commands around the tabs loading in Firefox config but it does not matter, the extension bypasses them no matter what. Only deactivating the extension resolves the issue.

I tried deleting and re-adding the extension. Nothing at all. It is sad. We pay for this service and it doesn't work. Please fix it. The issue happened to me yesterday as Firefox updated to latest version.
