There are no "3 dots" at the right end of the address bar. Is there another way to take a screen shot?
I have seen the advice about clicking on the 3 dots in the address bar to take a screen shot, but there are no dots in the address bar. I cannot find any other option for taking a screen shot. Is there one I am missing?
Hmm, your Firefox identified itself to the forum as version 53. The ••• "Page Actions" menu was added in Firefox 57, I think.
The current release is Firefox 63. If something is holding you back from upgrading, please let us know so we can suggest solutions or workarounds. Version 53 is not secure; Mozilla discloses security flaws after each new release.
Sometimes Firefox reports the wrong version because that information was saved in a preferences file. If the "About Firefox" dialog or "Troubleshooting Information" page shows Firefox 63.0.3, you may need to clear out that incorrect information. See: How to reset the default user agent on Firefox.
And finally, there are add-ons for capturing screenshots if Mozilla's extension doesn't work for you.
