I-Firefox Isithangami Sokwesekwa

In most instances I can click on the solid black return arrow. However in an increasing number of instances the return arrow is gray and clicking on it does not result in a return to previous page. This is a problem when I am reviewing my emails. In order to return to the previous page, I have to cancel the operation and return to my home page, then go to my email page. This is a nuisance. I am using 10.6.8 operating system.

I've noticed this on various sites, but I'll use YouTube as an example. I'm sitting on my YouTube 'home' page and I see a set of 'suggestions'. I click on one of the suggested vids and watch it. Afterward, I hit the 'back' button in the browser (there is not an embedded back button in the app). Sometimes hitting the 'back' button takes me back to the same YouTube page with my suggested videos and I can watch another. Other times, hitting the 'back' button causes a new page to load and I now have a new set of suggested videos displayed. This behavior is not consistent - sometime the page load occurs, other times the same page appears. I cannot detect a pattern to this. What's annoying about this is that there may have been more than one thing I wanted to view on the initial 'suggested videos' section of the original page displayed. However, after watching one of the vids and hitting the 'back' button, if a new page loads, I now no longer have access to those other suggested vids I wanted to watch. As I noted earlier, I've seen this behavior in other apps too. I don't know if this is the right place to ask about this, or if it's a browser thing at all, I'm just trying to understand what's causing this behavior and figure out if there's anyway for me to mitigate it.

Ever since the upgrade to Firefox 76.0 on Windows 10 Pro ... sometimes I click on a link ... then click on the back button ... I am returned to the top of the page instead of the location from which I exited the original page

I have seen this reported several times ... with the workaround of Open Link in New Tab (which I have had to use for YouTube for several years) ... but now all pages (including my own) ... exhibit this problem

I have started Firefox in safe mode as well as with all plugins disabled ... and the results are the same

The page in question is my BOOKMARKS.html from this or any other profile ... if that helps

When searching on Google I sometime click on a link that takes me to Facebook. As soon as this happens the back button is greyed out and I have to close the window and restart my search. Why are Facebook allowed to have this annoying feature and is there a way to stop it?
