Firefox for Enterprise Community Forum

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.

We have an application running on Firefox and noticed that with new Firefox ESR, Ajax call (XMLHttpRequest ) from js script running on Firefox browser on thin clients seems to be blocked frequently (same call succeed most of the time, but blocked from time to time). Issue was raised starting with Firefox 128.2.0esr), but in general persist with newer Firefox ESR. We tried replacing XMLHttpRequest with fetch which seems making no much difference so far.

We've been noticing for some time now that we haven't been able to load the Microsoft Bookings Page using the Microsoft Store version of the Firefox web browser.

Here's what we have tried and what we know: -We cleared cache and cookies using the "Everything" drop down option to no avail. -Confirmed that we are running the latest version and no extensions are running. -Tested running it in "New Private Window" to no avail. -Tested Diagnostic Mode to no avail. -Tested Refresh Firefox to no avail. -We confirmed that we are able to login and load the Microsoft booking page using different browsers (Edge, Chrome and even Firefox directly from their own page) with no issues. - We confirmed that different users can replicate the issue and can be replicated on a different computer as well. -We confirmed that we are able to access other Office 365 web apps with out an issue on the Microsoft Store version of the Firefox web browser.

Microsoft Support stated that they are able to replicate the issue on their end, but advised to reach out to Firefox support to investigate this further.

Feel free to let me know if any other information would be helpful such as .HAR log file(s) etc.

Thanks!

I confirmed this problem on two separate computers(windows 7 and windows 11) and version 115.23.0 of Firefox ESR can not properly play streams on twitch.tv

Audio will play, but the video does not load with only a black screen with question mark icon replacing video feed.
