how to stop tab closing when i scroll?

[coy_archivist]

does anyone know how to disable the act of closing a tab when you scroll too far on the left on firefox?

i noticed only this morning, when i scroll all the way back on the left to check my mails, if i scroll a bit too much it closes the tab? it never did that before, i often have a lot of tabs open and then scroll a lot to the left to go back to my mailbox/main tabs, and now it closes them?

if anyone know what keyword look for in about:config? i searched scroll or tabs, but there is a lof of them and i'm afraid to mess up!

thank you!

I can't reproduce that. Does that also happen in Troubleshoot mode (https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode/)?

hello!

it didn't, then i restarted the usual, to see if it could be an extension, but it now stopped happening. 

i am unsure of what i did differently, but the problem seems to be gone for now!

thank you!
