Hi Alexey!

Sorry to hear you are having issues with your mouse and the scroll-wheel. There have been some similar issues related to Extensions being the culprit.

You could Restart in Safe Mode to see if the middle scroll wheel works. To do this :

1. Click the 3-bar menu at the top right corner of your web browser
2. Click Help
3. Click Restart with Add-ons Disabled...
4. Click Restart
5. Click Start in Safe Mode
6. See if that works in Safe Mode by trying to scroll and open new tabs.

If you are able to scroll. Try disabling each extension(if you have any) one at a time as suggested : Suddenly my mouse wheel does not scroll a page as before on various web pages, but on some pages it works fine; Why? {link}

See related article : Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems {link}

Let me know if this helps or if I could assist you further.

WMagicModel, I'm a pretty experienced user. And as I said, it's not about add-ons/extensions. I understand when there may be problems because of them. However, I checked again with the plugins disabled, but the problem still remains.

Problem 1: I can't click the scroll to move the content on the page. Problem 2: Tabs sometimes open in pairs.

Hi Alexey,

I understand you're still having issues with your scroll mouse and multiple tabs opening in pairs.

Just to double check, have you tried to clear your cache/cookies as some may have been corrupted resulting with these issues.

Did your mouse come with any new Drivers you could install? Maybe you could check the brand/model and make sure it is up-to-date.

This might be difficult to check, but if possible see if your mouse works with (Firefox) on another computer to eliminate any hardware issues and compatibility with your web browser.

it was just to turn on "Use autoscrolling"...

Hi Alexey, thank you for reporting back. That should be turned on by default, so it's strange that yours was turned off on a new installation.

Did you resolve the issue with two tabs opening instead of one?

Note that you can duplicate a tab by holding down the Ctrl key and dragging the tab in case your mouse driver software modifies key pressses as well.

the problem with opening double tabs was associated with a double-click mouse scroll (Cougar Minos x5)

Hello. Excuse me for my poor English, I was translating with the program. Recently assembled a new computer, quite expensive and powerful. And there was a problem with Mozilla Firefox. No other browser has such a problem. Namely: pressing the "scroll" button on the mouse does not work, i.e. I cannot hold down the "scroll" button and move the content of the page up and down and right and left. How can you turn on this button, as it was before on another PC. This is the first problem. The second problem is that when you create a new tab or open a page in a new tab, two of these tabs are created (attached image). Two identical copies. It's as if the mouse is double-clicking. But that's not true. I checked in other browsers. The mouse is new and working. I also checked with all the disabled add-ons. Help me solve these problems. Thank you.

ScrollTabs adds scroll buttons on the left and right side of the tabs container if not all tabs are visible. It also adds a mouse wheel listener on the container. How it works If either a button is clicked or the mouse wheel is used over the tabs, a 'scroll' event is being fired. This event contains the node elements of the new and old active tab, and the direction in which the tab has changed relative to the old active tab. How to use Provide a tab container var $el = (

); var scroller = scrollTabs($el, {

 selectors: {
   tabsContainer: '.my-tabs-container',
   tab: '.my-tab',
   ignore: '.ignore-me',
   active: '.i-am-active'
 }

});
