When I click on a new tab, it still shows me the webpage of the tab I was previously on, but the new tab is highlighted.
Example:
I am on tab B and I have ~5 other tabs open. Browsing is normal. Randomly, when I switch from tab B to tab A, tab A shows that it is selected and the URL changes in the address bar, but the website that shows is the one of tab B. I still even scroll and type and interact with tab B, but on the top bar, it shows that it's tab A. So none of my 5 tabs show what they're supposed to show and basically only show me tab B, but I need to go do work on other tabs.
The only way I can fix this problem is to close firefox and started it again (restart), but this is time consuming and I shouldn't have to do that.
This has happened at least 5 times within the last 2 weeks.
