Zero regrets: Firefox power user kept 7,500 tabs open for two years

In brief: For most of us, having more than a couple dozen browser tabs open at once feels like a cluttered nightmare. But for one software engineer, managing nearly 7,500 active Firefox tabs is just another day at the office.

Hazel, who prefers not to share her last name, is what you'd call a hardcore Firefox fan and self-proclaimed "tab hoarder." She recently posted a screenshot showing a mind-boggling 7,470 tabs open simultaneously in the Mozilla browser. Turns out, Firefox had some trouble restoring the gargantuan tab load initially, but Hazel was able to revive the vast digital collection via the browser's profile cache functionality.

"I feel like a part of me is restored," Hazel wrote on X after getting her 7,000+ tabs back from the great digital beyond. We've all felt that little pang of anxiety when our browser crashes with tons of tabs we've been meaning to get back to, so we get it.

But what's the deal with Hazel's extreme browser usage? In her words, the memory impact of running that many Firefox tabs is actually "marginal." The session file containing all 7,470 tabs is only around 70MB in size, and Firefox optimizes things by only loading tabs into memory if they've been opened recently.

This aligns with what Mozilla told PCMag about the browser's ability to handle extreme tab hoarding. A Mozilla representative confirmed that having countless tabs open consumes "practically no memory whatsoever" in Firefox.

"We're working hard to provide people with even better tools for managing dozens to thousands of tabs," the Mozilla spokesperson said. "While we think it's amazing that anyone has 7,000 active tabs, it also shows the degree to which tab management is a common problem."

Indeed, tab groups have been a highly requested Firefox feature for years now. If it had that functionality, users like Hazel could easily group together all 7,500 of their open tabs, minimize the group, and temporarily pretend that massive tab debt doesn't exist – at least until they need to dive back in.

Currently, Firefox users can create different user profiles to segregate workflows and open tab sets, but more granular tab organization is on the way. Mozilla says it will roll out an improved profiles system and new tab management capabilities later in 2024.

In the meantime, there are third-party Firefox add-ons that can help tame tab situations like these to a certain extent.

I thought 50 was a lot... It makes sense. You save a bookmark, and it is somewhere away from your eyes among many other you probably already forgot about. Tabs are open. In my case, I can go back and finish few videos IU started or get back to a site I visit.
 
I have a specific FF plugin that lets me unload tabs at will. Makes for super easy management of the (at most) dozen or 2 tabs I might have open on any given day.

Though, I generally try to keep it down to a few when I can. I don't understand the point in keeping dozens upon dozens of tabs open (unless you're doing in-depth research and neeeeeed them open).
 
My tab count rises over time, even with periodic culls via the Tab Stats extension (side note: it's awesome; I use it to do things like close duplicate tabs or all bugzilla tabs, etc).
Right now my primary desktop has 9803 tabs. Others machines have 500-2500.
I find that they work as better bookmarks - they have history, which is often very handy. They also have a spatial meaning - related tabs are usually near each other, or tabs from a similar point in time.

Pro trick: "% word" in the awesome bar will show you matches only from open tabs.

Fyi, I work for Mozilla. Someone there wants to use 'jesup' as the unit for 1000 tabs. I.e. Hazel has 7.4 jesups open. Amusing...
 
How...why?
I think the most I've had open at once is around 10.
Close them when they're no longer needed, close the browser whenever I'm done with my sessions/load up a game.
Old habits die hard I guess.
 
I switched from Firefox after they killed (the classic) TabMixPlus and then forced everyone on to the annoying infinite scroll to go through tabs. Now I use Vivaldi and have a good amount of tabs open and easy ability to navigate through them.
 
I have 'only' 278 tabs open right now, but it varies up and down by a hundred or more over time. This is the main reason I keep going with FF as my daily-driver. Its memory use is infinitessimal compared to chromium-based browsers.

I use Opera as my secondary browser, and it starts to balloon up in memory usage quickly after running for a while with lots of tabs and multiple workspaces. I _always_ have to exit Opera before playing any games. Sometimes I can get away with leaving FF open, but usually I need to kill both. And that's with 64GB ram.

I use Vivaldi only occasionally - it's mainly there as my 'delete browsing data since the beginning of time' browser, for when one or another annoying site starts paywalling me after I've read a few articles.

As another user noted, TabMixPlus was an awesome tab manager, but eventually I adapted without it. Highly recommend 'Tab Session Manager' to perform regular automated backups of all tabs.
 
Firefox is still my favorite browser.I'd like it to have native vertical tabs though and why not tab tree view.
 
Sheesh. I mean, I probably have like 100 tabs (split between several windows), but I do close some once in a while. I guess I won't judge, though, I could probably cut mine down to like 5 or 10 if I wanted to.
 
***Warning to everyone***

Firefox has one stunning flaw that Mozilla ignores for ages, so if you have a lot of tabs open (I have 200 tabs), and set Firefox to continue where you left off (do not clear history)

and if you have opened a private window, closing the normal window before closing a private window, ends up killing all of your tabs forever, I wanted to kill myself IRL :-(

Install the Tab Session Manager extension. At least going forward you won't have that concern.
 
I doubt I have 7,500 things I could think to open a tab about. There must be a few duplicates in there. Has she never heard of the ‘favourites’ bar?
 
6,500 on just my youtube profile. my main I won't even count. let alone all the backup .jsonlz4 I have, to which I probably will never come around to browse lol

what @jesup said. it's easier to browse. with vertical tabs this is a no-brainer.
 
Started using Firefox ten or fifteen years ago and have never looked back, you couldn't bribe me to use Chrome or Edge or anything else for that fact.
