Every https page fails with certificate errors in K-Meleon for some reason.

Correction & Note:

TL;DR: K-Melon Goanna engine is the LIGHTEST PWA ABLE WEBBROWSER @ 51mb on USB ready to use


K-Melon Goanna engine UPX'ed single language & default skin only = 51mb (53,566,636 bytes), making it the lightest PWA app able web browser avaible as of 2020-11-15


Gecko engine & Presto engine webbrowsers no longer load youtube, not will D-plus (dillo for windows) QtWeb or Netsuft (very sad)

K-melon (goanna version), then palemoon (current to "many" firefox extensions) & last, seamonkey (heaviest light but current to "almost all" firefox extensions) are lightest non-trident (IE11+, like Avante browser) that load Youtube & web sites with HTTP5; 100% CORRECTLY

Goanna engine version is 100% PWA able, but you need to save "link" manually (no "install to desktop" support).

It is a 51.4mb minimal install to USB drive vs Palemoon's 73.5mb.

Opera@USB is lighter at 18.1mb, but can no longer load youtube, and can not handle PWA apps

Hi All,
I just couldn't resist posting about KM 76 Goanna because I haven't had any problems with it and it's really been fun learning about this browser over the years.

Developers and moderators are so compassionate and concerned about this browser and also about what the users think.
It really makes you feel like getting involved no matter how small or big the remarks or suggestions might be.

It's definitely a community forum effort and they will go out of their way to help you with your technical problems.

It's funny...even though these releases aren't stable, I've never had any qualms about downloading any of the versions.
I don't worry about little mistakes in programming but when things start crashing down around me then it's time to uninstall.
I've never had to uninstall any KM version and if I ever have to,
I'll just go to the next version or the version before, whichever I have to do.
Are any of you developers? Maybe you could give them a hand over at KM Forums:

For what it is worth and from my experience, official and stable regarding K-Meleon can be a rather fuzzy concept... ;)

The versions you mentioned are not yet official stable releases.


Midas 2018-05-15 07:09

Thanks for reporting, Happy.Camper2 -- as an old user, it surely interests me.

Hi Everyone,
It seems like I've been using K-M forever & I still like this browser very much.
Actually, this browser has definitely been getting better & better over the years.
roytam1 has been developing K-Meleon 76 Goanna since 12/15/2017 & every week on Saturday there's a new version. I look forward to the new versions each week...

I really wish KM 76 Goanna was listed here at TPFC.
I think this browser is very enjoyable & I'd like everyone to
enjoy it as much as I do.

Take care all.
