This is my rig: www.bit.do/kanishkpc and I use the latest Firefox Beta (always updated)

I have been using Firefox without the kind of memory usage that I am seeing recently. With ~10/15 tabs open, my PC would never be troubled. The RAM usage wouldn't be at 90% but in the past few days (possibly because of a beta update?) I get 50% RAM usage (8GB) with 15 tabs. Yesterday concurrently loaded ~6 YouTube tabs caused a 90% usage from the app and I had to close it.

The RAM usage might seem normal but Firefox actually never uses that much RAM - or didn't earlier at least.

I used MalwareBytes a few days ago to do a malware scan and it found my PC clean. If I did have malware (I had a bit of scare earlier), how would I detect it?

Hi everyone,

I am having trouble getting my custom new tab page to be focused when opened (instead of the address bar).

I am currently using the `autoconfig.js` + `mozilla.cfg` approach to overriding the `AboutNewTab.jsm` service with a custom local file. This is working great with the two files containing this code:

autoconfig.js: ``` pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0); ```

mozilla.cfg: ``` // Custom firefox config

let { classes:Cc, interfaces:Ci, utils:Cu } = Components;

try {

 Cu.import("resource:///modules/AboutNewTab.jsm");
 let newTabURL = "file:///home/vallode/Documents/test/index.html";
 AboutNewTab.newTabURL = newTabURL;

} catch(e) { Cu.reportError(e); } ```

I have been attempting to use the `gBrowser` global to add an event listener to the new tab opening, but with no success. Could anyone point me in the right direction for something like this?

HTML5 Games freezes on Firefox 79.0b1 Dev.Edition

Hello, i've just updated my firefox developer edition from 78.0b9 to 79.0b1 (64-Bit) Now a HTML5 Game in the first tab freezes when i'm opening a website (google or mozilla or any other) in a second tab. Occures with the HTML5 Versions of Shakes&Fidget and Forge of Empires, which i play. No problem with latest version of the normal Firefox (77.0.1 64-Bit) and the previous dev edition 78.0b9 64-Bit. My OS is Windows 10 Pro Version 2004 Build 19041.329

Thanks in advance, Nicole

I'm using Firefox Beta on a slow laptop in Linux -so, manually changing videos to 360p from the cog works to make them play smoothly. The facebook SD Only setting in https://www.facebook.com/settings?tab=videos doesn't really work -only in a few videos. If anyone knows of an extension that handles this on latest Firefox Beta let me know. Thank you.

JIT/GC/Cycle Collection hanging periodically

After my browser being open for a while, usually a few hours, Firefox starts to get some major hanging in some tabs; I can have two windows open, one with a youtube video playing and another with like reddit or something else, and when browsing reddit, I get major hanging when interacting for around 7 seconds.

I recorded a couple performance profiles to see what's causing it, and it seems to consistently be a very long JIT or GC call, also labelled as "Cycle Collection" in the waterfall view.

I saved the profiles and I can upload them, but I'm not sure if they come with any private info so I'm reticent to add it to this thread.

I've watched the Task Manager (the Firefox one and the Windows one) while this is happening and memory usage in the Windows task manager seems to rise quickly over a few seconds then suddenly drop back down. I'm not sure if that's relevant. In the Firefox Task Manager I didn't see anything particularly salient other than energy usage spiking up just after the hanging is over.

This doesn't only seem to happen on Windows because it also happens on my Linux laptop occasionally as well, in a very similar manner. I didn't collect any evidence on Linux yet.

This has been happening for quite a while now, on multiple versions of Firefox in a row. I'm using 79.0b3 Developer Edition right now on my Windows machine.

Closing and reopening Firefox usually causes things to clear themselves out and I don't get such long hanging for a while.

I would expect JIT and GC to happen in much smaller chunks to avoid hanging, it's strange that it takes that long for one call.

Firefox completely stops canvas rendering after switching back from a tab

I have been facing this problem from some of the recent versions where:

  1. I open a tab with an HTML 5 canvas [please see note 1 below] with some drawing animation or even online games
  2. I switch to another tab, wait for a couple of seconds there.
  3. Come back to the previous tab (point 1 tab) and see the beauty of frozen canvas (completely stopped rendering)

[note 1] For the test, I also have an open source app that has the canvas (no ads): http://jmblr.rf.gd/?i=1 ... </div>

Here you click on a word, then click on the organized words, that will open a background tab in duckduckgo. Then come back to the tab of jmblr.rf.gd, you will see it. If you can't see, try opening a couple of more tabs, maybe wait 2 seconds for each. Won't take long for the freezing experience.

Now this doesn't only happen with my apps, but also with other apps, and games (well this feels bad to write a site full of crappy ads, but I played subway surfer on www.poki.com and the game froze in a similar way when I switched to another tab).



Recently I was playing subway surfers online, and then switched tab, then came back and saw the game is frozen. It's happening for a month or two now...

I have tried different sandbox levels from about:config (because I previously set "security.sandbox.content.level", and "security.sandbox.socket.process.level" to 0), tried the default one, nope that's not a problem here.

What's going on?

When navigating Patreon, I have noticed that Firefox Nightly bogs down/becomes unresponsive within the first few links. This trend has also been observed on Ebay, and other image heavy websites. Previous versions of Nightly (approximately 1 week ago) did not exhibit this behavior.

The regular edition of Firefox also exhibits this behavior.

Firefox Developer Edition remains more stable/responsive. However there has been a decline in its responsiveness as of the July 18th update.

I have tried to create an account on bugzilla to report these issues in greater detail, However I am not receiving the activation/confirmation email required to complete the account.

Hi!

I've added a new device and am trying to synch it (my new laptop). My account shows everything synched (history, bookmarks, log-ins). However, none of my previous history is showing up. None of my old bookmarks are visible.

Either something didn't work right with synching, or (much worse) all of my Firefox bookmarks, history, and log-ins have been lost. I have no way of knowing what the problem is, since everything shows as being correctly synched on my laptop when I view my Firefox account.

Please advise.

Thanks!

Jeff
