I know these two environment, and it helps with webpage scrolling only. In some menu, like history menu, it does not scroll but drag the text only. Better file a bug report.

Thanks for reply. Report on bugzilla

Originally in that post, I commented that the bug is caused on Firefox nightly. But later, I find out the bug is caused by misconfigeration of no-scripts, so I detete the comment and post another one.

Maybe I should edit the comment next time. Sorry for inconvenience caused.

I reproduce it with no-script addson enable. Should be some wrong setting in the extension cause the problem.

And I am surprise how the bug exists for years and no-one brother it. Anyway, it’s going to be fixed in future.

Yes, you can get it at here

No. I am too broke to buy the license of gnome :(

Seem like not happening on me. Maybe try using external image host (like shota.nu) next time?

after a few testing, it seem it is caused by no script of my browser. Thank for your reply.

It’s Wayland. It happen with gtk based app, especially the menu button. It’s always the menu button not working.
