Last night Firefox on my laptop did an automatic update and installed a new Firefox browser than can only display 1 tab .. Pleae help !
7/7/2026 Last night Firefox on my laptop performed an automatic update to the latest Firefox version. The new Firefox has a very bad setting in about;config .. this new Firefox can only show 1 tab ... it is opening up a new tab on top of the first tab, making it impossible to have more than 1 tab ..
This is going cause problems for thousands of Firefox users .. . how I fix this problem ... I tried setting the add tab settings into about;config to add a new tab to the right of the current tab, but my change made no difference ... how can I fix this problem ... does Firefox have a plan on how to fix for this problem for thousands of Firefox users.. this problem will impact thousands of Firefox users..

Hi
I would not recommend altering about:config as that may cause further issues in the future.
Please appreciate that you appear to be using the extended support release version of Firefox. The functionality you manetion may be included in the main Release version.
Have you tried this in a copy of the Release version of Firefox?
