A webpage is slowing down Firefox (107.0)

Just today 30 nov 2022

Is it just me? while moving and copying some files decided to watch something on Youtube and this message just appeared: "A webpage is slowing down Firefox", ok... I thought, perhaps the copying is taking too much resources? not that it makes sense entirely (didn't have any other open apps), just copying files.

Decided to turn on my Microsoft Surface and watch a video there (on Youtube) but the browser started behaving strangely, slow and the same message appeared time after time while trying to do anything on Youtube (360p, yes, not even using higher resolutions). Restarted the Surface, same issue, did this a couple of times: same issue, after finally managing to watch a video the mouse vanished, closed Firefox and without any windows open the audio continued... that's weird, so I turned off my Surface.

After finishing the file-copy session on my desktop computer decided to restart and booted from my second hard drive (not partition: entirely different hard drive) and experienced the same issue "A webpage is slowing down Firefox". What? so I restarted back again with my first hard drive (SSD btw), and I get the same message just by opening Youtube.

Just as opened this thread, checked my FF version to post the details (107.0 64-bit) and suddenly a new update begins to download, is this a causality? or did they break something? I'm restarting FF after posting this.



107.0

Ok, after restarting, I'm on 107.1, just had ONE window/tab open (youtube) and turns out FF ix using 3.2gigs of RAM. Just checked memory usage internally with about:performance, and turns out Youtube is only using 37mb of memory, that's what the FF report says. What´s happening?

The thing is, the weird behavior is suddenly happening on 2 Windows systems on the same desktop computer, and also on my Microsoft Surface out of the blue.

Firefox is denying some location information that sites try to collect. It started after a recent update.

It's not a Firefox issue, the site you are connecting to is denying page load momentarily to try a few more times.

It seems to go away once a cookie is set but if your browser clears cookies on browser window close the slowdown persists next time.

I'd just put up with the slowdown. Don't reward bad behavior.

That's weird, I didn't get any of these messages yesterday, it's not happening across all my devices running Firefox today, specifically on Youtube (I don't see yet the same issue elsewhere).

Thanks. My FFxs don't clean the cookies or seesions on exit, but it does deletes cache.

Mine is 107.0.1 but I am not on Win, it may be different on Mac 64 bit, not sure.

That's weird. I was in here when FF showed a Download Available and I clicked for it to download. Then I left and turned FF off to reload the newer version. It is showing 107.0.1 as the new version, same version I had earlier today.

Aaand just now I read that some browsers (not Chrome yet) are dropping a root certificate authority (TrustCor) with ties to government contracts and some intelligence spyware. So that might be why there have been oddities in FF updates (?) and/or possible slow connection negotiation.

Major web browsers moved Wednesday to stop using a mysterious software company that certified websites were secure ... Mozilla’s Firefox and Microsoft’s Edge said they would stop trusting new certificates from TrustCor Systems

Strange. My settings for "delete/clear" cache on exit were gone, unchecked. Something happened on my FFx installs yesterday taking place a while after being online and closing/opening again, pretty sure an update, and then later while manually checking I noticed an incoming 107.0.1, things remained weird until the end of the day. Checked with a few websites and the issue happened only on Youtube.

During the night everything was running ok again, all my FFx versions are on 107.0.1 today.

Yes it sounds like an update not going transparently fine.

Ive seen this previously, but not often, and it's a script that is causing the problems. I haven't seen it in a while.
Stop the script and it seems to resolve.
