Firefox Clogged

Hello, I’ve noticed sometimes that my Firefox starts clogging and gets super slowed down to the point I can’t do anything in it. I’ve checked System Monitor and the PC is not overused, nor Firefox is using CPU extensively. All other apps work fine, I can also happen to be gaming meanwhile. It’s just Firefox that gets clogged.

I am on latest Manjaro, I have NVIDIA GPU with Nvidia Drivers… I can provide any info needed in case.

Also, for firefox … make sure to check against your configurations, for example safe-mode;

firefox --safe-mode

I notice your BIOS is very out of date.
(and updates include processor support, ram compatibility, speed, etc)
If my search-foo is correct

Yeah probably, because I never touched my BIOS in my life

I have this problem on occasion, it’s always tied to bad code in advertising. I get those warnings, something to like “this website is slow.” I close FF and start anew without going to that website and everything is fine.

People should probably be making use of a (decent) adblock method.
I use a number of things … ublock:origin in the browser and optionally hblock on the system should be enough to avoid most problems.

For extra steps you can achieve something similar but better than noscript by using a minimum of medium mode with noop rules

* * 3p-script block
* * 3p-frame block 

No no I don’t get any site warning honestly.

Yes, I have UBlockOrigin, but I have this exact same Firefox build on Windows (copied the user profile to Manjaro) and it works flawlessly, so I don’t think it’s that

Know what’s better than thinking that?

Knowing it.

So try it with a clean profile first, that way you can know, because I don’t have that problem:

firefox --profilemanager

If that works for a day or so, longer than you’d usually have to be working to experience he issue, try your previous profile again, but disable all extension and themes. Enable them one-by-one to test them individually.

Once you’ve encountered the experience again, you know what theme/extension is causing it.

My guess is some extension causing havoc on Linux.

Firefox needs some kind of clean/refresh after certain time of usage, what I do normally is:

  • Clean browser cache
  • in about:support launch “Clear startup cache” and restart
  • If above steps do nothing, then in about:support Perform “Refresh Firefox”, it will remove your extensions and customization but keep your history, bookmarks and passwords.

I’ve never had to do this in the ±3 years’ Manjaro installation…

I use many extensions with Firefox, and the first problems that always happen on my laptops after a period of usage is that the browser takes long time to start and to connect to internet, and also takes long time to load YouTube and Facebook websites. After doing those cleaning steps, my browser becomes fast again.

This is not a problem specific to Linux, on Windows 10 it’s much more severe, the browser always needs to be periodically cleaned and refreshed.

I do too. I think 85:

$ ls -lah ~/.mozilla/firefox/ | wc -l

…so I still suspect it’s some extension, but yeah, Windows is a lot worse.

I don’t run adblock because I want the sites I visit to make money so I can continue to read them for free. Besides it’s an infrequent problem I can deal with on my own. No desire to install 85 extensions, yikes, have fun diagnosing that.

I find the use of more than 1 or 2 a bit messy, beyond 4 or 5 is pretty much unthinkable.
Something like 82 (gotta subtract a few for non-ext directories and the .. . things created by the ls string) is probably a medical condition. :sweat_smile:

The ‘I allow ads on the whole internet because I want to support these handful of people’ is a very old (but not very good) argument.

Do you click on a few too, because they are click-generated revenue?
(otherwise they dont get the money?)

Or no, because they are time-leases so they are still supported?
(in which case they get the money regardless of you viewing it?)

And you really support website to such an extent, that even when they serve you ads so horrible they crash your browser … that you still want to allow them all?

And whats to stop you from having it enabled on most services, but disabled when you really support bloggyblog123?

Etcetera … but … as I said, its old arguments, so a handful of the familiar hits are good enough for now.

:rofl: Not disagreeing with you! :rofl:

But it does serve to illustrate my point that “many extensions” is no reason for what he described…

I didn’t use to mind ads…when they weren’t half the page or more…now even the, supposedly “free” sites are clogged with 'em.

Similarly I didn’t use to have a worry or care about so-called bloatware on my phone. Until I remove most, if not all Samsung applications out of boredom and curiosity.

And the phones battery life skyrocketed. Literally doubled.

Not me having to diagnose anything.
