Whenever I press SHIFT in twitter message form, or on forms of some other sites (but not in this form), I get weird behaviour, like:

  • removal of the previous symbol, or
  • acts like i pressed HOME, or
  • does not type the symbol at all.

GIFs are attached (in twitter):

  • in one of them I literally type <write SHIFT> but get only <write F>
  • in another I type <press """"">

(ignore symbols < and >)

This behaviour is in *safe* mode already. Related is this unanswered reddit thread: https://www.reddit.com/r/firefox/comments/7jdmll/firefox_57_issue_shift_key_deleting_text/

Chrome works perfectly; ~one year ago, firefox worked perfectly.

Firefox Quantum 61.0.1 (64-bit), Ubuntu 16.04, T420 thinkpad laptop.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window

Try the Firefox version from the official Mozilla server if you currently use a version from the repositories of your Linux distribution.

As I wrote in the original post, I tried the safe mode.

I just now tried the default theme (in safe mode) and a latest version from the server you mentioned.

The same problem.

I also tried a new keyboard, the problem persists.

Too bad that SHIFT works fine in Chrome, otherwise we could blame it on your device (not necessarily the keyboard, but the motherboard) .....

See these search results

Question : Does SHIFT behave the same way on the on-screen keyboard  ?

Thanks for reply. Yes, on-screen keyboard produces the same results. Just recorded the video of the twitter form. The same for right-shift. CAPS lock works as expected.
