does this still happen when you run firefox in safe-mode?

Start firefox from command-line like: firefox -safe-mode

Thanks,

disable your extensions one by one until you find the one that causes
this issue then.

apparently an extension bug.

[John Nelson (skyfalcon866)]

i have disabled all my extentions and uninstalled them and it still happens.

This issue just started to happen to me.
Sometimes opens two or even three tabs of the same thing.

Firefox: 82.0 (64-bit)
Ubuntu 20.04.1 LTS

Boris, have you tried what Alexander was suggesting in earlier comments? I.e. start firefox in safe mode, to find out whether the problem might be caused by an extension.

[Boris Rybalkin (ribalkin)]

Yes, just did, restart in safe mode. Also removed all the extensions before that.
Issue still persists.

[Olivier Tilloy (osomon)]

Can you try the following?

  - run `xev -event button` in a terminal, this will open a small white square window
  - do one click with the scroll wheel inside that window
  - close the window
  - verify that the output in the terminal has exactly one ButtonPress event and one ButtonRelease event
  - repeat a few times

Please share your results here. Thanks!

Hi, it actually shows two events sometimes:

xev -event button
Outer window is 0x3400001, inner window is 0x3400002

ButtonPress event, serial 25, synthetic NO, window 0x3400001,
    root 0x57c, subw 0x3400002, time 192169015, (41,34), root:(803,559),
    state 0x10, button 2, same_screen YES

ButtonRelease event, serial 25, synthetic NO, window 0x3400001,
    root 0x57c, subw 0x3400002, time 192169071, (41,34), root:(803,559),
    state 0x210, button 2, same_screen YES

ButtonPress event, serial 25, synthetic NO, window 0x3400001,
    root 0x57c, subw 0x3400002, time 192169096, (41,34), root:(803,559),
    state 0x10, button 2, same_screen YES

ButtonRelease event, serial 25, synthetic NO, window 0x3400001,
    root 0x57c, subw 0x3400002, time 192169191, (41,34), root:(803,559),
    state 0x210, button 2, same_screen YES

ClientMessage event, serial 25, synthetic YES, window 0x3400001,
    message_type 0x146 (WM_PROTOCOLS), format 32, message 0x144 (WM_DELETE_WINDOW)

So that's a hardware problem with the mouse itself, or with its driver.
Not with firefox.

It could be that with time, the spring that maintains the scrollwheel in place has become loose.

Thank you very much, sorry for that :)
