My Browser Builds (Part 5)

... Is that about PR#3024 having been merged in 5f03b88 ? Will your decision be viable in the long run?

So long I understand, you compile your UXP builds on a Win7 SP1 x64 build machine, don't you? There exist CPython-3 forks that have restored support for WinVista+ (so Win7, too), e.g. 

https://github.com/adang1345/PythonVista

, will using such a py3 version during compilation render your browser builds not compatible with XPSP3/VistaSP2 ?

If the need arises, I've also come across some py3 builds (> py3.4) that are XPSP3+ compatible, like: 

https://github.com/R-YaTian/CPython3.6.15WinXP/releases/tag/3.6.15

https://github.com/R-YaTian/CPython3.7.17WinXP/releases/tag/3.7.17_final

https://github.com/R-YaTian/CPython3.8.20WinXP/releases/tag/v3.8.20_final

python3.10+ changeset changes build infra which exists everywhere in the tree. as my tree already very different from upstream and merging it will need extra time on fixing differences.

in windows, mozillabuild package provides almost everything to run UXP's build infra, and bumping to python3 also means newer mozillabuild is needed and it is not tested with my tree.

@roytam1, you may have seen that wuggy has made an other UXP fork.

There may be things that are interesting for your forks, he also worked on performances apparently.

Dactyloidae UXP fork: https://repo.dactyloidae.xyz/Dactyloidae/UXP

Some of those improvements might get merged by mainstream: https://repo.palemoon.org/MoonchildProductions/UXP/issues/3030

had a look, many commits in his repo look messy and 1 commit combines many unrelated changes.

I'll just wait until he cleans-up and put them in MCP's repo/issue tracker.

Same here, on basilisk52

Also, when trying to log in to Paypal, I get a captcha (often a slider) which I can't get past on Basilisk.

... Previously known as "ownedbywuigi", so that probably means 

https://repo.dactyloidae.xyz/Dactyloidae/UXP

is a continuation of recently archived 

https://github.com/OwnedByWuigi/UXP/

PS: Since they've only released 64-bit  binaries, I can't test here whether "Dactyloidae" even supports WinXP SP3/Vista SP2 32-bit ...

Just suffered the Cloudflare issue.

I didn't have problems along the week til now, using the 20th of March version of NewMoon 28. But if you have problems too, is not the version.

I know, it's just another captcha that doesn't work here.

I got two more crashes within a couple hours with the latest IceApe-UXP

Here are the drwatson log file in case it would help.

Notice for my source code users: I'm NOT going to merge upstream's python3 changeset.

Thank You for that decision! If your UXP fork can still compile using Python 2.7 and Mozilla Build 2.2, I would like it to stay that way.

Yes, the Cloudflare just keeps looping with high CPU usage. Maybe my computer is too slow to solve it in time. Cloudflare is on an increasing number of sites now.

Yes, that is almost my thought too, but maybe not the computer, but the JavaScript engine on NewMoon. Unless I have some option missing to enhance its performance.

Because I'm on a Core 2 Duo (we would agree it is slow and old), but with Firefox 115, that runs JavaScript waaaaayyyy smoother, as the tests are completed in a split second, not as NewMoon, that struggles, instantly shows the test is OK at https://browser-compat.turnstile.workers.dev/
