One of the features in Firefox which is very annoying is the tab scrolling buttons when you have a lot of tabs open. I’d prefer to just see all the tabs on the screen, even if they are small.This is tutorial to disable this feature
Steps to Follow
- Type in browser.tabs.tabMinWidth, or at least type enough that it narrows down to the option you are looking for.
- Set the option browser.tabs.tabMinWidth to 0 to completely disable this feature. You could also set it to a smaller value like 50 or 75 if you wanted to.
