Notice: a 5-yearly electricity equipment check is re-scheduled in 03 June 2026 (10:00-16:00 UTC+8). Download server is unavailable during the period. And just in case machine can't automatically power-up after this outage it may be needed waiting me to go to the site to troubleshoot so the outage ending time may be postponed due to this.

they also checked-in lots of other things, bug parallelized GC and FinalizationRegistry may cause browser strugglish and/or crashy. EDIT: decided to back-out FinalizationRegistry here, GC-on-close-tab was backed out as well.

1. build palemoon27 repo with https://github.com/roytam1/kmeleon/blob/master/goanna-xulrunner-km-adapt.diff applied, and build with mozconfig "ac_add_options --enable-application=xulrunner" 2. copy built xulrunner's objdir/dist/* to xulrunner-sdk inside kmeleon folder 3. apply kmxulr-sdk-goanna-240425.diff 4. open k-meleon/k-meleon10.sln and build 5. after k-meleon.exe is built, copy k-meleon binary files from Release to xulrunner-sdk/bin and run there

Notice: next build will bring you libdav1d instead of libaom for AV1 decoding, not fully tested but looks like working from my limited testings.

maybe someone is mass-downloading in the moment. you may try again to see if problem persists.

Update: electricity company postponed this to early-June, exact date will be notified later.

Notice: a 5-yearly electricity equipment check is scheduled in 21/5/2026 (10:00-16:00 UTC+8). Download server is unavailable during the period. And just in case machine can't automatically power-up after this outage it may be needed waiting me to go to the site to troubleshoot so the outage ending time may be postponed due to this.

mine is already better than upstream. upstream's version will always trying to full load all cpu cores. because not only parse thread goes multithread, upcoming version will also have #3075 implemented which means multithread jit builder. for some systems, multithreading could mean more struggling. I'm thinking if I should undo these in IA32 branch so -ia32 and -sse builds should behave like earlier builds.
