In such cases forced to switch to Chrom where things work just fine.

Can you reproduce this with a clean profile? How are you copying/pasting (keyboard, context menu, main menu, toolbar buttons, ... ?) Are there any errors in the browser console (ctrl-shift-j) when pasting fails? Are you using a distro build of Firefox, and if so, can you reproduce on an official build ( https://www.mozilla.org/en-US/firefox/all/ ) ?

either do not work.

>Are there any errors in the browser console (ctrl-shift-j) when pasting fails?
No errors.

> Are you using a distro build of Firefox, and if so, can you reproduce on an official build ( https://www.mozilla.org/en-US/firefox/all/ ) ?
No, from openSUSE distro. Not reproducible with an official build.

Changed branding package now from MozillaFirefox-branding-openSUSE to MozillaFirefox-branding-upstream, seems works now, thanks!

It might be worth filing a bug with opensuse (I'm not familiar with them, so can't really help, sorry!).

Marking this one WFM for now.

After some period of work (open some tabs, Youtube, etc) problem appeared again: can't copy-paste to an input.

Still exist in Firefox 47, Linux Mint or openSUSE Linux.

I take it this happens with an official build as well? Can you post the contents of about:support?

This really needs proper triaging. At this stage I have no idea what would cause this, but it's clear it doesn't happen to everyone all the time or it'd be failing automated tests and we'd have dozens of dupes of this report. It could very well still be a Firefox bug, but we need to narrow down when/how/why exactly it happens.

[Aleksey]

Yes, reproducible with official build as well. Content attached.

My best guess is that it's related to one of your add-ons, but I wouldn't want to take any guesses which one. I'm guessing this doesn't reproduce in a new profile?

Scrolling issues appears time to time, not reproducible in clean or my regular profile for now.

Closing this as Worksforme then. If you can still reproduce the issue on a clean profile, feel free to reopen.

This happens after session restore, also I can't load more often visited sites list (from URL bar) in this case. Think it is connected with Bug 1259133.

[Aleksey]

P.S. If I restart FF then - all works fine.

Hi, 
I tried to reproduce the issue on Firefox 49 but I could not. After session restore I can scroll the pages, can copy-paste text, and can load visited sites from URL bar. I tried on Ubuntu 15.04.
Do you still reproduce the issue on the last release (FF 49)?

Comment 17

[Aleksey]

Not reproducible in FF 48 as well for me now. Will check 49 when update available in Linux Mint.

Comment 18

[Liviu Cirdei]

Thanks Aleksey. 
Please leave a comment after you check 49 too.

Comment 19

[:Gijs (he/him)]

We're going to need a lot more info here to move forward, and it seems the reporter could no longer reproduce, so going to close as incomplete. We can reopen if there's enough information that points out there's a specific problem for Firefox to fix (rather than an add-on breaking things), and then move it to the right component when we actually know where/why things are breaking.

Not reproducible in 49 for now.
