Tabby. A tab manager, but I mainly use it to search for tabs.

Sidebery

CAD Cookie Auto Delete

Tree style tabs

Makes it simultaneously easier to open a billion pages but also manages them nicely

I’ll throw out a few.

• LibRedirect

• Chameleon

• NoScript

Consent-o-matic: automatically rejects cookie banners, even the most annoying ones.

Multi-account containers. Let’s you have 2 different Gmail accounts open at once. Also I try to silo different parts of my life to prevent tracking.

Noscript and tampermonkey too.

Sponsor Block–Skips some YouTube ads.

Language Tool–keeps me from making stupid grammar errors.

Cookie Quick Manager–you can lock cookies and other stuff.

Bitwarden.

Oooo, PopUpOff

Haven’t had to deal with annoying “LeGiTiMaTe iNtErEsT” cookie pop-ups for nearly a year. Honestly forgot they existed until I needed to deactivate it to briefly log back into my reddit account recently (I swear that entire website’s UI is just malware at this point).

Their website is also surprisingly gorgeous. I was surprised since most app makers usually don’t put much effort into something people are probably only gonna see once, if they even have one at all. It’s so well put together.

Snowflake - help others bypass censors

Port authority - stops port scanning of your local network [and I found out how many fucking assholes do this. My own employer freaking does it >:( ]

The one I want to point out the most is WebScrapbook, which is alternative to SingleFile. It can either snapshot the current DOM or the document source (handy for PDFs), can use proper directory structure and provides full-text search over the stored pages.

It has support for separate server should you want to keep the files outside browser storage or share an instance between several browsers. I use this with text browser as renderer to make summarizing pages into VimWiki easier.

Unfortunately it can’t do sync between instances, that’s something I wanted to add to it but I’m currently juggling way too many other projects.

Then there’s Feed Previews for getting those RSS/ATOM feeds where they still exist so I can avoid using the browser, or worse, getting notifications through antisocial media. (-:

Web Archives is making access to webpage archives much more convenient. Especially useful when dredging through old academic research pages full of link rot, or using TOR and getting locked out constantly.

For managing tabs I’m sticking with the venerable Tree Style Tabs together with few handy plugins like TST: Colored Tabs and TST: Unload Tabs.

While I prefer keyboard control for most things, and certainly Tridactyl goes the furthest from existing addons, it just can’t really handle all the screens as it was possible with the XPI addons. sheds a tear

For content blocking it’s the run of the mill uBlock with JS disabled by default (F8 mapped to selectively enable it on a page) and LocalCDN which has rule generator for whitelisting locally provided resources in uBlock.

And because some sites are broken mess and don’t work even with conservative Firefox setup I’ve had to use Allow CORS once or twice.

Non-addon bonus: Searx-NG has a CSV output which can be integrated with tools like rofi or dmenu so you can do web searches outside web browser and easily pick the result.

In no particular order;

• Unpaywall - for research papers tries to find legal and free copies of them
• Stylus - overwrite style on a per-website basis (I use the Compact Subscriptions style on YouTube, for example)
• uBlacklist - additional to uBlock that deletes some URLs from search results (such as an anti-AI list, or Pinterest from image search)
• Surmount - jumps over paywalled news articles using archive.ph

Adnauseam Silently click-spams ads to drain their bandwidth, with the purpose of making the horrible advertising business unprofitable.
