Wow you have quite a lot of it. I use opera and I only have one: I don’t care about cookies.
I do not use any blocker in browser because I have Adguard Home on Orange pi zero.

I have a bunch for Chrome...

Here's the ones that I actually use.

Amazon URL Shortener - automatically shortens those long Amazon URLs

Fakespot Fake Amazon Reviews and eBay Sellers - gives feedback on Amazon reviews

find+ | Regex Find-in-Page Tool - helps me find "(new)" on BLF for new posts

Image Backtrace! - does a bunch of stuff, but I use it to do reverse image searches easily

Images downloader from amazon - makes it easier to download Amazon images

Images ON/OFF - makes it easy to disable images for any website like IMDb for example

Keepa - Amazon Price Tracker - keeps track of Amazon prices over time, like The Camelizer or The Tracktor

Photobucket Hotlink Fix - makes some PhotoBucket images appear

PriceBlink Coupons and Price Comparison - helps find deals when online shopping

Recent Bookmarks - helps you find your most recent bookmarks

ReviewMeta.com Review Analyzer - gives feedback on Amazon reviews

Secure Bookmarks - lets you have some bookmarks that are password protected

Stylus - does all sorts of things on different websites. I use it to block annoying stuff

Take Webpage Screenshots Entirely - FireShot - takes complete website screenshots, but it doesn't always work right

Toolbar Dial - replaces the New Tab page with a colorful grid of bookmarks and folders.

uBlock Origin - excellent for blocking avatars or signatures that you don't like

Wow thats a lot. I just use AdBlock addon and I use Opera.

Its defaults are so secure/private it breaks things occasionally, but I’m still really liking arkenfox

I don’t always agree with their reasoning, but Privacy Guides is generally pretty good.

I can’t live without SwitchyOmega (firefox and chrome). I can easily switch my browser between direct browsing, my personal VPN, or work VPN.

Bitwarden is just as essential in all my browsers.

Proxy SwitchyOmega looks pretty cool.

I wonder if it would work with my VPN, except I don't use my VPN for web browsing.

Just PrefBar on old FF.

All new browsers suck ass. Extensions are like slapping perfume on a pig.

“wink”

Yep, feel free to block my images if you like.

I don't block hardly any images on BLF, but I belong to an "adult" website where I block most avatars and signatures.

I’ve been using Bitwarden for a few years now. Easier to use than Keepass, and the Android integration is super nice.

Also, another vote for Keepa for Amazon price tracking. Super useful for identifying all the fake “sales” on Amazon these days. Combine that with Fakespot to make browsing Amazon slightly less annoying.

That’s just not true unless you mean from a subjective User Interface standpoint.

Your old FF installation likely has unpatched security vulnerabilities. And Mozilla reworked their browser engine for better performance and stability a few years back so you may be missing out on that. Does your old Firefox block ads on Youtube videos? That’s just one of the benefits of Ublock Origin.

Wellp, javascript doe not work for local files, ie, those you access with file:///.... And “turning it off” still allows it to be “partially on” and still do things I don’t want.

And I still want to be able to turn it on/off immediately (a la PrefBar), and not have to dick around with about:config or similar nonsense.

Yeah, it may be the UIs that are the biggest problems, but underlying stuff is still broken.

Rotate and Zoom Image
License: MPL 2.0
Platform: Firefox
Synopsis: It allows to rotate and zoom images directly on any website from the image context menu.

Print Edit WE
License: GNU General Public License v2.0
Platform: Firefox
Synopsis: Edit the contents of a web page prior to printing or saving. Elements in the web page can be edited, formatted, hidden or deleted. Unwanted content, such as adverts and sidebars, can easily be removed

This a brilliant add-on. This addon can save customized pages as they are displayed as a single HTML file or PDF and even works with Dark Reader.

You can do this manually using “inspect element” or developer mode in a browser. But it sounds like this plugin makes the process less time-consuming. Nice one!

I mentioned this in another thread...

I use the Chromium-based extension called Midnight Lizard.

It allows me to do a sort of custom Dark Mode on many websites.

I don't use it on BLF, but I use it on many sites.

You can choose many, but not all, of the main colors of a site.

I have a lot of dark blue chosen, which is not good for natural melatonin production at night, but I don't really care about that.
