Are there any active, up-to-date browsers which have the following capabilities (all present in Opera 12.x and older versions):
- separately block / allow image display on each open tab (some tabs will have images blocked, some won't, and some will display cached images)
- ignore a site's built in CSS, and apply your own (again, on individual tabs). Something like this.
If none of the new browsers have these capabilities, are there any add-ons for, say, Firefox, which can provide what I'm looking for?
It should run on Windows XP, though I'll settle for something that I could run on Ubuntu 16 (through VirtualBox).
It should run on Windows 7, or any Linux distro.
I am aware of Firefox's Reader view option and View > Page Style > No Style option. That's not quite what I have in mind, though it does ignore a site's CSS.
