bad perf/memory on some sites [A: bad website design + webgl disabled]

[Obegg]

🟥 https://github.com/arkenfox/user.js/wiki/5.2-Troubleshooting

• [x] I have read the troubleshooting guide, done the checks and confirmed this is caused by arkenfox

🟪 REQUIRED INFO

• Browser version & OS:

  Edition Windows 10 IoT Enterprise LTSC
  Version 21H2
  Installed on    ‎3/‎23/‎2024
  OS build    19044.4170
  Experience  Windows Feature Experience Pack 1000.19054.1000.0

• Steps to Reproduce (STR):
  1. Download and install Firefox.
  2. Download and run arkenfox.
  3. Visit https://app.tvtime.com/ and https://my.bezeq.co.il/#/dashboard_screen
• Expected result: Pages will not be slow, memory usage will be low.
• Actual result: Slow page performance, can't login, high memory usage:
• Console errors and warnings: ?
• Anything else you deem worth mentioning: First noticed on my main machine, later on tested on a fresh install of windows on VM. On the second website (bezeq) it will have high memory usage. This is the default arkenfox user.js, there are no overrides. As I said - tested on VM, so I also tested it without arkenfox and there were no issues, this is caused by arkenfox.

Not even going to try to diagnose or confirm memory/perf

both sites seem to use webgl - try that

• close Firefox, reopen (so everything is sanitized)
• open about:config, type webgl.disabled and double-click it to false
• test

If that's not the pref then try privacy.resistFingerprinting

There are some basic very common prefs that cause 99% of all issues, listed in the wiki. TRY them - I just listed two

Thank you, this has fixed the issue.

listed in the wiki. TRY them - I just listed two

I'm sorry, but I don't think this webgl.disabled perf is well mentioned in the wiki, I'm saying it because I did look at the wiki and I did already try to change privacy.resistFingerprinting perf, As the webgl.disabled perf is part of FINGERPRINTING part - I ignored it. And even here - https://github.com/arkenfox/user.js/issues/1080 it's part of FINGERPRINTING, on top of that - this is the note:

// 4520 [mostly pointless if not using RFP]

[Thorin-Oakenpants]

I can't tell for sure, but if webgl is required then the site won't work anyway - it's not just your memory and perf - it's bad website design

[Thorin-Oakenpants]

out of 9 items listed on the wiki - 3 are directly web site related - all the rest are usability issues (retain logins, history, etc). I don't think a 9 item list with webgl, RFP and strict pinning is making anything too hard to find

webgl also has a [SETUP-WEB] tag - as per the wiki [SETUP-WEB] can cause some websites to break
