I currently have 2014 tabs in my session (almost all unloaded, using around 2GB of ram that I wouldn't use otherwise). I had 1600 tabs a few days ago. They are links I clicked on in other apps or browsed to over the past few months. When I get a chance to plow through a few dozen/hundred of these tabs I can read/view them and close them very quickly. Notice all the UI stuff I don't have to do: I never had to perform…

In terms of UI stuff, how do you find a tab among a thousand? When the tab page title shrinks and all I see is favicon, I feel lost.

In all honesty chrome is by far and away the worst at handeling large numbers of tabs of all the browsers (bar perhaps version of IE).

> The way I use Firefox is that having 50 or more tabs open is normal for me I've never understood this. Isn't that what bookmarks are for?

I used to do somethingng similar but I've been using reading lists and a little more self control to manage most of my favs now.

I had the same experience though I have to admit that some things in Firefox are better these days, like checking where an event comes from, going really deep into objects, referencing other objects, comparing rather big objects. The only thing I really miss is a view WebSocket frames. In many other cases I ended up preferring Firefox Dev Tools which I think while a bit harder to get into are more powerful. But that…

The only thing I'm missing in either browser is the ability to ignore jQuery as I'm debugging. Stepping in and out of jQuery (and other libraries like underscore) is a pain.

The Firefox debugger should automatically blackbox minified sources. You can also click on the little eye icon in the debugger panel to manually blackbox sources.

You can also use the developer toolbar to run a command like `dbg blackbox --glob *-min.js` etc. to blackbox a bunch of stuff at once.

Now if I can only fix the wobbly address bar that changes size depending on Back/Forward availability.

Can you please post a bug (with screenshots, list of add-ons installed, and any custom browser css tweaks) to https://bugzilla.mozilla.org/ and CC :callahad in Bugzilla?

Those sorts of fit-and-finish bugs really bother me, and I'd love to figure out how we can fix that one for you.

From the experience I've had with Chrome, I would say that process per tab is overhead. Sure, there are some benefits from having a few processes that are managing different parts of the system, but not hundreds of processes just for browsing. The way I use Firefox is that having 50 or more tabs open is normal for me, sometimes there are even hundreds of them. Currently Firefox works great and although there are some…

"There are multiple competing factors when it comes to choosing the right number of processes. - For security, more processes is better; one per tab is probably ideal. - For crash protection, ditto. - For responsiveness, one process per CPU core is probably best. - For memory usage, one process is probably best." as a dev wrote in the mailing list: https://groups.google.com/forum/#!topic/mozilla.dev.platform... For v…

This summer I'm going to be working on an implementation of software based fault isolation for my masters degree. We are looking to sandbox a web server without the need to partition via processes and incur expensive interprocess communication and context switching. I don't see why it couldn't work for Firefox either.

Please please test battery life impact while implementing the Multi-process stuff. I had to move away from Chrome just on the battery life issue. I suspect (but cannot conclusively prove) that the multi-process crap that Chrome has just drains your battery much faster. And yes I am perfectly aware of the supposed fix in Chrome for the battery killing bug.

Safari is multi-process and it has the best battery life.

Safari makes use of a kernel feature that allows giving some leeway for when the process should be woken up again (eg. from a timer source). That way the kernel can put the CPU to sleep until it can schedule as many processes as possible at once to wake up and perform their work. That way the CPU doesn’t have to wake up all the time to wake up a single process and let it do its work.

Is Firefox really better than Chrome here, or is it worse because it is enabling bad user behavior?

ctrl-shift-e should open a canvas like area where you can group tabs. Similar to a file folder, I prefer it to bookmarks

Interesting, but seems to be very basic. I still prefer using a wm. I can use different layouts, group windows into hierarchies, display them side by side, take advantage of tiling, use workspaces and have configurable keys for each of these actions. You know, functions that a wm is built for. And I can always switch to a different wm altogether if I'm not comfortable.

Once you get used to the tab groups they can be very powerful. I use them for contexts myself; one for casual browsing, one for development for client x, one for client y etc, one for research, and the list goes on.

Obviously you can easily achieve the same thing in separate windows as well, so ultimately I suppose it doesn't make a huge difference, but it's the way I find makes for the biggest difference in separating workspaces.

What extension do you use to unload your tabs? Or keep them unloaded, not sure of your workflow in that regard.

I use one called UnloadTab. Works a treat, and does exactly what it says on the box!
