And I assume you've already got uBlock Origin. And as others mentioned, try also using Firefox as your mobile browser, so you can send tabs from one to the other, which is pretty neat.

- SponsorBlock - Automatically tag and skip portions of youtube videos, such as sponsors, intros, recaps, and others. - https://addons.mozilla.org/en-US/firefox/addon/sponsorblock/

- Firefox Relay - Automatically create up to 5 (for free, more if paying for it) email addresses that redirect to your actual address, to avoid giving your private address to everyone. - https://addons.mozilla.org/en-US/firefox/addon/private-relay...

I'll be sure to keep Relay in the back of my mind, I haven't had need of it yet.

Though I do have requirement for SponsorBlock avid watcher of YT that I am, I am a little hesitant to add SponsorBlock as I am not quite sure how it would work flawlessly without some really complicated algorithms potentially involving ML work. I am curious to know if in your experience it has ever erred and automatically skipped portions it wasn't supposed to ? Or any other type of errors ?

I have never seen bad section tagging over the past two years.

This is a good start for a but what I'm looking for is Local Full Text Search of every page in my history. It shouldn't be hard to automatically maintain a text index of the pages I've browsed so that I can search them by keyword without bookmarking everything. Maybe it's just me but chronological history is useless beyond a few days.

Why don't you just search the add-ons? This would have taken less time than to formulate your post.

You could have just pasted the URL. When someone here asks a well-formulated question I assume they've done their research first.

I would add in a couple more, for anyone tempted to switch away from Chrome or Safari:

- Redirector: https://www.einaregilsson.com/redirector/ Very helpful for redirecting "new" reddit to old.reddit.com, AMP links to normal links, Twitter to Nitter, etc.

- RES (Reddit Enhancement Suite): https://addons.mozilla.org/en-US/firefox/addon/reddit-enhanc... Provides built-in image preview and lots of other subtle goodies for old.reddit.com. I have a very hard time browsing reddit without it!

- Sponsorblock for Youtube: https://addons.mozilla.org/en-US/firefox/addon/sponsorblock/ If you watch any amount of YouTube on channels with lots of sponsors, this is a great way to keep your sanity. Works just like sponsor skipping in the Overcast podcast client.

(Sorry for the lazyness :P)

This is the biggest reason why Chrome sucks - they have no workable version of vertical tabs.

Reasons why horizontal tabs are clearly inferior:

1. Screens (generally) have way more horizontal space than vertical and you read webpages vertically. I already have an OS top bar and a browser top bar taking some of this valuable vertical space.

2. Most webpages have predefined right and left margins, so vertical tabs don't take away from the visible space of the page.

3. The size of the tab header is critical for being able to read the name of the tab. I have my vertical tabs set to 30 characters. If I had horizontal tabs with 30 characters, I could fit maybe 6 tabs on the screen at once.

4. Ease of having many more concurrently open tabs. I easily have 38 tabs open and visible without scrolling. 8 of those are pinned tabs which take up the space of one tab. I use 6 different windows (which are category titled using the Titler extension). That is 228 tabs open at once and very easily accessible and readable. (of course I use Total Suspender to keep them from taking too many resources)

All this said, Firefox still sucks because vertical should be the default or at least a simple toggle. As it is, you have to trust some extension and then you have to jump through obnoxious hoops just to get the damn horizontal tabs turned off. And yes, there are some other browsers that have vertical tabs built in, but I am not touching Edge or Opera as they are from dubious companies. I also think that Brave is working on it, but they seem dubious as well.

Now to my complaints about Sidebery (which is superior to Tree Style Tabs). Sidebery has tree style as well, but I turn it off as it undermines the value of #3 above. It has panels, which are goofy and, while you don't have to use them, you still lose a tab worth of space for it. You also lose an even larger tab space to the Sidebery title (which is a menu and an X that aren't necessary. Sidebery doesn't work well with the Titler extension - when you want to move a tab to another window, it doesn't show you the title.

Opera was very much a not-dubious company. But that is what it has turned in to.

-- I use Firefox as my main work-browser, and have for a long time, and the last few years I've used Vivaldi as my main personal browser.

I find it easier to just have separate browsers rather than do anything more advanced for context. :)

Firefox has a really great json viewer that I prefer even over my IDE, but it's one weakness is it's lack of XML support which Chrome does have :/

This matters when you can't 100% trust your browser session, or the installed extensions. Did you ever load https://my.1password.com in your browser? How do you feel about it? Do you trust your installed extensions to not take a peak? I don't.

Chrome solves this elegantly via profiles. Even more, you can install websites as “apps”, with a shortcut that gets indexed by the OS, and Chrome remembers the profile. I simply type “1Password Online” or “Banking” and my Chromium opens a new window in my “Private” profile that has no extensions installed. Firefox dropped the ball on both PWA shortcuts, and on profiles.

Even for using multiple accounts, I feel like Chromium profiles are a better solution.

For example, my workplace has very strict security requirements, and when looking at company documents it's not cool to provide access to extensions like LanguageTool or Grammarly. I'd be in trouble. And Chromium always had finer grained permissions for extensions, like activating or deactivating them per website.

That said, containers are a handy tool for people who want to access multiple accounts without the trouble of setting up individual profiles. Keep in mind, if you're only trying to access a personal and work Google account you probably don't want to spend time setting up a separate profile for each then keeping the settings synchronized.

Starting a profile is difficult, and also switching between windows, since the OS sees profiles as different apps. It's probably not hard to fix, but Mozilla has had other priorities.

I don't know why they don't add this somewhere in the menus and I don't know why you can't bookmark about:profiles, but this works well for me as it is.

You can create shortcuts (or shell scripts) by hand with --no-remote -p ProfileName to auto-open specific sites in specific profiles. It's certainly less convenient than PWA installs, but is an old tool with all sorts of old ways to automate it.

Multi-account Container is far easier than all that though and does reduce the number of windows to manage in your OS taskbars. Obviously you need to be careful with which extensions you install that they are safe for every container you want to use, but that's a given and a good idea in general no matter how many profiles you use: keep extensions to the bare minimum you are comfortable with. Vet their permissions manifests and keep additional permissions you grant them to a minimum.

I have to log into multiple Microsoft365 tenants and it drove me crazy with the amount of signing OUT I needed to do when switching accounts, to the point where my crappy workaround was to use different browsers for each account (Chrome, Firefox, Edge, Opera, Brave, etc) but I started to run out of different browsers.

This multi-account container extension is a godsend

I do that, no chance for one to leak into the others.

FF containers are more work than the 2 clicks I do now, powered by some Python I wrote like 15 years ago (with minor maintenance).

For instance, I can't have Youtube Music playing something on one profile while doing a Google Meet on another profile in a different tab (has to be the other profile window). In Firefox it's site-based (and tab-based) but Chrome locks down on any Google site.

Finally it's actually really hard to undo multi-profile in Chrome once you switch to it, I had to throw out all my Chrome profiles to get back to the old, preferred behavior.

It's sort of like everything opens in a private browsing window, except the stuff I've whitelisted.

This lets you set regex/wildcard to contain subdomain or redirect happy sites into a single container

You can configure 10 different tabs in extensions settings

I simply use Temporary Containers to isolate tabs (or different domains) and login to websites either by hand or via KeepassXC's browser integration. No per-container setup needed, every tab just lives briefly in its own little container.

1. Further defense in depth against common XSS attacks: if you only ever log into banking sites in a Banking container, then some random ad-sprung malware trying to access your bank in any other container will never find a logged in banking session to hijack (no matter how good your bank thinks they are at XSS protection and auto-timeouts).

2. Isolating tracking cookies from major ad companies. This reduces cross-correlation between/among them. I have separate containers at this point for all of: Google account usage, Twitter account usage, Facebook account usage, and Amazon account usage. The amount of targeted advertising I see decreases every time I sequester one of these major accounts into its own container. The trade-off is the increase in ReCaptchas needed and the increase in advertising companies complaining I must be using an "ad blocker". (I don't have any ad blocker extension installed, just this strategy of isolating major cookies to specific containers and Firefox built-in Enhanced Tracking Protection.)
