Github commit messages don't come up on Firefox 52 based XP compatible browsers

When you visit https://github.com/python/peps using any of those browsers

basilisk-55 (serpent)
bnavigator-0.9
centaury-0.14
iceape-uxp-52.9_20200905
k-meleon-76.3.1
mypal-28.14.2
palemoon-27.9.7 (New Moon)
slimjet-10.0.13

the commit messages which are in the middle of the page don't ever come up and worse still the browser uses the 100% of the CPU. That url was just an example. It happens on many other Github pages too. On some of the Github pages it doesn't happen for instance on https://github.com/python/cpython it doesn't happen.

Here is a screenshot using the bnavigator-0.9 browser visiting the Github url: https://github.com/python/peps



Here is another Github URL on the same browser visiting the Github url https://github.com/python/cpython



Among all the Windows XP compatible browsers I've tried so far, only those 2 didn't cause this problem. They are:

firefox-52.9.1 (original Firefox)
maxthon-5.2.4 (trident or webkit based)

 

I use firefox and mypal and the issue does not occur with my browsers, therefore it would appear to be some setting on your system,

 

Well I wish it was really some setting on my system but have you actually clicked on the link https://github.com/python/peps
I've just tried clicked that link on mypal-28.14.2 on both Windows XP and on my Windows 7 64bit laptop. and on both machines that github commit messages column didn't come up. Here's a SS from the Windows 7 laptop:

 

https://github.com/python
the two below open fine, but the other four do not, now if some will open but not others from the same page it would seem to me that it is the other four uploads that may be the problem (pythondotorg, Peps, devguide, and typeshed)

mypy and cpython

 

There's a fine detail here: The mypal-28.14.2 (64bit) on Windows 7 does open the https://github.com/python/peps fine but the same mypal-28.14.2 (32bit) on Windows XP doesn't open it.

 

Weird. When I first went to that GitHub page the commits wouldn't display. I cleared the cache and restarted the browser and now it displays normally.



But when I open the cpython page the commits don't display unless I clear cache and restart the browser. I don't get 100% CPU usage but it does slow the browser to a crawl if I have more than one GitHub tab open.

Centaury x86 0.0.7 Windows XP SP3.

 

On Windows 7, the Bnavigator displays the https://github.com/python/peps normally but the Centaury and the Iceape browser just dont't, even after I cleared all the cache. There's really some sort of incompatilibility problem among some of the Firefox based browsers and that problem should be addressed ASAP because it causes 100% CPU load (about %50 load on dual core CPU's) and when left unattended, that may cause hardware failures because of overheat.

 

I experienced the same problem with MyPal in Windows 7 x64 but not Waterfox. Seems to be a problem with legacy Mozilla browsers javascript renderer since it's intermittent.

There is currently only 1 person maintaining XP compatible browsers so I don't know how ASAP this will be addressed. You are always going to encounter issues when running legacy software and systems. You just have to learn to live with the quirks or use a modern OS/browser.

 

I have some good news. I've found a fix. On this link https://support.mozilla.org/en-US/questions/1231257 titled
All github repo are broken and says "Cannot retrieve the latest commit at this time."

it is suggested to clear the cache before clicking the Github pages in question. I've cleared cache on BNavigator (2021 01 30 version) and clicked the link https://github.com/python/peps which would always fail to display the commit messages, and it did finally dislay the messages.
Note: I haven't tried this fix yet on other browser such as Serpent, MyPal, New Moon, etc.But this being fixed on BNavigator is enough for me because it's the browser I use the most often
