Ask HN: What browser extensions are a must-have in 2021?

I was kind of forced into the Dark Reader way of life and I love it. I got a monitor with Adobe RGB color gamut. I have no use for this, and the OS doesn't understand it, so by default all colors are wrong. I know it's wrong and it makes me mad. So I put the monitor into sRGB mode. But in that mode, you can't adjust the brightness and so things are way too bright. I use dark mode for everything, though, so it's not too bad. The improved contrast ratio is actually excellent, and I much prefer a too-bright monitor in dark mode to a dim monitor in either bright or dark mode.

Dark Reader was the missing link for web designers that won't make a dark mode. Honestly, in a lot of cases it does a nicer job than the designer, so for a few sites I opt out of dark mode and let Dark Reader do it for me.

HN is one of the hardest sites to get right, however. It seems to change every version. My current configuration is: Dynamic, Contrast +20, Grayscale +100. I lose my topcolor, but everything else looks good. (This changed with a recent Dark Reader update. I had everything perfect, but the algorithm changed, and so I compromised on this. A few weeks in, and HN looks normal to me. If I saw the unmodified page, I don't think I'd know which site I was on!)

I stopped trying to whitelist sites. Now I just use cookie autodelete and container tabs.

Full list:

- Joplin web clipper

- BitWarden

- Firefox containers

- Containerise (choose tab container based on domain name or url regex)

- Cookie autodelete (in case I ever accidentally log into something in the wrong container, this cleans it up)

I also modify the search bar so it only suggests locations from my bookmarks, and I use separate bookmarks for each account, eg:

- gmail [user@gmail.com]

- gmail [other@work.com]

- aws console [prod@work]

- aws console [me@personal]

- github [work]

- github [personal]

I type "gmail work", hit return and Firefox opens it in the correct container tab, already logged in. (Honestly, who uses bookmarks any more? They just turn into a bloated to-do list, hundreds of links you'll forget about until one day you try them and the domain no longer exists)

Make Google results suck less with Greasemonkey and a script that blocks junk domains (I maintain my own block list). And I have a junk Google account just for random searches etc, and I leave that logged into the "default" container tab, so I'm not plagued by Google cookie / T&C pop-ups.

Other Greasemonkey scripts, eg: make Reddit suck less by using old.reddit.com.

I also log into Firefox and sync this stuff across all of my browsers. Unfortunately the setting per addon do not sync so I always export text configs to a Syncthing directory any time I make a change (eg: update containerise rules, blocklists, cookie autodelete settings)

Bitwarden - for passwords

Brave - for adblock built in

Sponsorblock - to cull all the youtube bullshit

Imagus - to hover over images and see the content without having to open a new tab

old reddit redirect - for the occasional google result that takes you to reddit

reddit enhancement suite - to remove all custom css from old reddit
