Firefox drops connection speed after a while

Hello,

since about 3-4 days I got the problem that firefox stops loading pages for some minutes. I first recognised it while watching a video on Youtube. The video stops buffering and eventually stops playing when buffer ran out. After a short period of time, mostly between 1 and 5 minutes, the browser continues to load the video. Other sites dont load aswell in this time. I checked the Youtube "Stats for Nerds" an could see that my connection speed drops from about 21k kbps down to approx. 350 kbps in this short period of time. Afterwards it gets back up to its normal level. Also, while this happens, watching my taskmanager I saw that firefox raises my harddisks usage from about 3% while idle to 95+%. This also drops down to normal after a while. While this happens, all other sites I try to open dont load aswell. I disabled all my Malware-Protection already without any changes to my problem happening. One thing that solved the problem was to run Firefox in safemode, so with all addons disabled. SInce this worked, i tried disabeling and even removing all my addons from normal firefox mode, but unfortunately, even on a clean reinstall without anything imported or any addons installed, the problem keeps on persisting in normal mode and is gone in safemode. I went to using safemode for now, but that doesnt work for me in the long run, since I want at least adblock back on.

I hope someone can help me out since this tends to get a little annoying :D

Some infos on my system: Firefox x64 Version 53 Windows 10 Pro x64 i5-6300HQ Processor @ 2.3GHz 8GB DDR4 RAM Nvidia GTX 950M, but Firefox is set to run on the processor graphics (Intel HD Graphics 530) Firefox is set to use hardware acceleration

Sorry for the weird formating, didnt know my linebreaks would be cut, so just imagine there would be commas or linebreaks inbetween my system specs :P

It is not your fault that the formatting is broken. Its an issue with the first post where they didn't add class="content" to the first post that prevents some CSS code (.content > p {white-space: pre-wrap;}) from getting applied to this first post. I see is as it is intended to show.

You can try to disable hardware acceleration in Firefox.

  • Options/Preferences -> Advanced -> General -> Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

You can try to disable multi-process windows in Firefox to see if that has effect. You can disable multi-process windows in Firefox by setting these prefs to false on the about:config page.

  • browser.tabs.remote.autostart = false
  • browser.tabs.remote.autostart.2 = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
