Reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
If it does work in Firefox Safe-mode then disable all extensions (Tools > Add-ons > Extensions) and then try to find which is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
To Cor-El..I appreciate you giving me a response. The problem is that I don't know enough of the terms you are using. For example, when you mention that the extensions will be disabled, I don't know what that means and it sounds complicated. I am game to try something, but, I would like to know what the outcomes are and the difficulty in getting the problem solved.
Extensions are used to customize Firefox.
You can see the installed extensions (if you have any) in Tools > Add-ons > Extensions.
Thank you, I did check as you suggested and I don't have any extensions. What would be the next step? And, thanks for your patience with this process.
Are you left clicking the link?
Does it make a difference if you middle click with the mouse scroll wheel (if you have such a mouse) or try top open a link in a new tab via the right-click context menu?
Can you open links like a bookmark in another tab with a middle-click with the mouse scroll wheel?
Hi, I have a MAC and my mouse doesn't have a middle scroll thing. You lost me with that second part of opening a link via the right-click context menu....what is the latter?
The right-click context menu of a link has an item to open a link in a new tab ("Open Link in New Tab")
You can try to create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
Is there any way to speak with you over the phone, it will simplify this whole process...I do appreciate the efforts you are making, but, it's getting
complicated, I think, unnecessarily so.....
