We recently update Firefox with version 138.0 and now getting the message "Gah. Your tab just crashed" when opening the browser.

We attempted to update and install version 138.0.1 only resulting with the same error. We also found and attempted the following all resulting with the same error: - change the about:config page for settings to false for both browser.tabs.remote.autostart and browser.tabs.remote.autostart.2

- clear browser cache.

- enable Temporary Mode in the Help menu. This appears to fix the problem but only for the current browser session. When a new Firefox window is opened, the error reappears.

What is needed to resolve this error or is there a way to permanently enable Temporary Mode or some similar setting? Thanks for all your help with this.

All of a sudden I am not able to download files on my MacbookPro in Firefox. I am using Version 126 on Mac OS 12.7.5 Monterey.

Downloads are working if I use Safari, but I do not use it. I just used it for testing purposes. Is anybody else having this problem? I've already "refreshed" Firefox per their suggestion.

Youtube won't work anymore. I've been watching youtube for years and now on Firefox and now it won't work anymore. For months now it keeps saying "Gah. Your tab just crashed". I've tried many things to fix but nothing works. Really annoying. Is it time for me to stop using firefox?

Thanks
