uBlock Origin

uBlock origin

• Reopen closed Tabs

I often want to reopen a tab i recently closed, so this is very handy for me.

• Languagetool

On the fly rule-based Spelling check. Works very good and in many languages. And the best: It's Open Source.

• Facebook-, Google- and Microsoftcontainer

Uses the Firefox Tab-Container Fwature, to lock those companies in Tab-Groups just with themselves. I don't use Tab-Groups aside of that, so it comes in handy.

• Firefox Translate

• (Not really an extention, but still nice) Firefox Gnome Theme, for my personal machines and Firefox UI Fix for the machines at work to make Firefox look more at home on Linux and Windows.

Ublock Origin, Privacy Badger, LocalCDN, Multi Account Container and Dark Reader.

• Checker Plus for Gmail - Great way for me to see incoming emails in multiple inboxes, and mark as read/unread or respond
• Open With - quickly open a webpage in another browser
• SponsorBlock for YouTube - skips ads and sponsor segments in YouTube videos
• uBlock Origin - The best adblocker
• Video Speed Controller - Allows you to change the speed of a video, outside the normally allowed range (some slower videos are much better at 3x)
• Snap Links - Lets you draw a rectangle and opens all links inside. Great for checking out a list of links, like the links in this comment, for example

Swisscows search engine, can't live without it

I see a lot of the same addons here, as one would reasonably expect, but I'm surprised there's been no mention of uMatrix. Using uMatrix and denying most elements by default, you can manually allow scripts, media, etc. per domain and save those rules for pages you go to often. It gives you more granular control than simply choosing to allow/deny all third-party scripts, and you can see exactly what's going on under the hood.

Anyone here use AdNauseam?

The ones I am unable to use a browser without:

• Sidebery
• Darkreader
• Bitwarden
• uBlock origin
• uMatrix (even if it won't get any more updates)
• Firefox Multi account containers (although I probably can just do this with Sidebery)

Nice to haves:

• Tabby
• Don't Fuck With Paste (this is really nice when login pages try to prevent password manager for “Security” reasons)
• Augmented Steam
• ProtonDB for Steam
• Imagus
• HTTPS everywhere (because websites still to this day can't set a proper redirect)
• Facebook container
• LanguageTool (semi open-source alternative to Grammarly)
• Invidious (this redirects YouTube links to invidious instance selector)(There are like 4 different ones, all not updated in 2–4 years, I am thinking of learning enough coding to support this)
• Tabliss (this is a nice new tab where I can add reminders of what I am supposed to be doing instead of what I am doing)
• Custom Scrollbars
• User-Agent Switcher and Manager

I used to have plugins for reddit (like RES and old reddit redirect), but won't need them anymore.
