Why is Android Firefox so slow?

I've used Firefox, Firefox Beta, Firefox Focus, and Firefox Nightly. They're all absolutely glacial browsers on Android.

Every time I click a link in FF (any version) it takes up to a second to even register I touched the screen, and another second on top of that to load a page. This is the same regardless of wifi or data.

It's kinda ridiculous. I wanted to get away from Chrome, but it's shockingly fast compared to FF on Android.

I have an essential phone, if that matters.

Mozilla is aware of Firefox for Android's performance problems and is rewriting it.

I don't know if they have a full grasp of what causes its issues or not, but they are aware and are working to remedy it.

Firefox Preview or fenix is a promising browser . It has modern superfast Ui . Better page loading time and benchmark scores . It is currently under development (that's why it's called preview ) . But ones Firefox mobile completely adapts fenix it will be a huge success . What we have to do is download and test the thing .

It's honestly showing A LOT of promise.


Edit: If you want a stable alternative then I've heard Bromite (Chromium based) is good, though I can't vouch for it myself. Personally I'm running both Fenix-nightly and Chrome.

Is it just me or do you think the scrolling on firefox preview is kind of inconsistent so far?

This is me comparing the scrolling with Samsung Internet Browser's scrolling which I don't know if you have experienced it but I feel like samsung's is a whole lot smoother and consistent.

I just started using fenix the other day and it's blazing fast

At least Firefox (fennec) has a better tab management than Chrome in some respects. I hope that the 'Fenix' versions use a similar implementation in the future.

I think it could be some Add ons which are optimized for much more cpu capacity than your phone actually has ๐Ÿค” Edit: because they are made for desktop i forgot to mention

Here it is usable. The main lag is when I enter an url, it starts a few seconds to start to load the page, but when it is done, it reacts as it should here.

I'm testing reference browser too, it is faster. Too slim on features, but since it is more a test browser than anything, that is ok.

I'm considering entering firefox preview, but maybe later. Nightly is already my main browser, isn't wise go more edgy than this.

Nightly is actually just really stable now because most work is now happening on Fenix.

It needs more UI feedback, at any given moment it's hard to know what it's doing or if it even registered my tap.

Can you provide some feedback here? https://bughunterissues.mozilla.community/

Just the way it's been for the non Windows platform. With the Android version, Mozilla is wisely rewriting for better performance.

I really don't have any issue with the performances of FF. I'm using a pixel 3a (so not the fastest device) and it works just fine. Chrome may be a bit faster but it does not prevent to use Firefox. O don't have many extensions so that's maybe that. The web is so much more enjoyable with uBO that I can accept a small anoyance here and there. I wonder if some phone/firmwares don't have an issue with Firefox.

I have the same behavior. I got frustrated a few times, but now I cannot take it anymore, I uninstalled it from my phone (Pixel 3). Now I don't know what to replace it with. I was using Opera, but some websites just disappeared from my history, so I've lost faith in them. Chrome is not an option, Brave doesn't have the mute tab option, and I don't know other ones that I can use on Windows + Android

I can try kiwi browser a chromium fork which support Chrome desktop extensions and is even faster than Chrome

I looked into this a while ago and what struck me was that Android on Firefox is essentially the same browser as the desktop version, with the only important differences being due to the UI. Phones are simply much less powerful than x86 computers, thus the poor performance.

Are they? Snapdragon 855 and 6Gb memory blows my PC out of the water honestly.

Focus shouldn't have worse performance, AFAIK its using the default Android web engine (same as chrome)

This isn't true anymore, Focus uses an early version of Geckoview, the core of Fenix.
