That’s all my extensions I have installed into Waterfox.
Make sure you’re using “Imagus mod” and not the old “Imagus,” which hasn’t been updated in 5 years. It also requires simple-modify-headers + the rules you can find on the subreddit to get the most out of it.
It’ll still work with a lot of stuff without SMH, but with SMH and importing the rules from that thread allows it to work with stuff like tiktok (though it’s somewhat finicky, I find hovering over the pause button works the best). You can even tap Z, then right click on a video and save it to easily download it. Also works on youtube if you don’t switch to the actual youtube player (left and right arrow keys).
Make sure to change the “disable on site” hotkey to something other than G, because it’s easy to accidentally disable it on a site and think it’s broke (speaking from experience.)
A lot of the comments recommend the same well known and popular addons. Instead I’ll give a couple of little known addons that I regularly use and love.
“Go To Playing Tab” when you have a silly amount of tabs open, if one has a video playing or some random audio due to a simple miss-click it can be a real pain in the arse to find the culprit among nine virtual desktops each having a firefox window holding a plethora of tabs. With that addon you click the button and it focuses the offending tab.
The second is “Maximize Video”, every bloody website these days has their own video player ui, often lacking the simplest of features like a maximise button. With that addon you click on the video and it gives you the standard firefox video ui, gets rid of any irritating right click hijacking. The video sits above any overlayed ads , for example when you just try to pause a video it’ll trigger some awful casino scam or hot singles in my area popups.
When you use maximise video all that nasty crap is pushed below so you can safely use the ui.
You might consider YouTube enhancer which provides some extra gimmicks for YouTube. It also provides a lot of customization so I suppise you might find something useful out there
Just switched to Firefox and as I have Malwarebytes I see that it added an extension, Malwarebytes browser guard. As I also vahe uBlock, shoul i Uninstall Malwarebytes?
I really enjoy simple tab groups (since Firefox doesn’t have native tab groups) and tabliss. Tabliss not really “essential” but it makes the home screen pretty on desktop.
I recommend the Chrome Mask extension. It enables you to spoof your user agent for any sites that think (incorrectly) that they won’t work on Firefox. It makes it really easy to switch between Firefox and Chrome.
uBlock Origin is an essential. The rest, like Bitwarden, are optional improvements. Privacy Badger is completely redundant with uBlock, so remove it and use Yokoffing’s recommended uBlock settings.
