Terrible slow response to mouse clicks

[bobbiemac421]

I am using Firefox on Linux Mint 19. At first, everything seems fine and gradually the response to a mouse click takes so long that I click again, then end up with a window opening twice, or whatever. Moving the pointer over a link does nothing unless you wait a long time. Etc. Unusable-can't be the way the guys who wrote it intended. They'd never have gotten the work finished if they had to use my computer (btw, about 4 year old HP desktop with core i5) . I think Chromium has the same problem.

Replying to my own post. I installed Chrome in addition to Firefox and Chromium. Chrome works just fine. I have not gone back to Firefox and Chromium to check as I was very happy to be rid of the issue. In addition, I have stopped using Gmail in the browser and started using Thunderbird. I'll post more when/if I find more info.

Do a killall firefox-bin while ff is running.
Reopen and all should be good.
It's a ff thing that is doing this.
I stick with ff even so.

If you are still interested in solving the trouble with Firefox:
Open in FF the hamburger menu -> help -> troubleshooting mode. Same behavior there?
