Falkon browser questions (sorry, quite long) (lemmy.kde.social)

Hello. I was directed here by someone who saw a question on this topic I posted at reddit. If there is a more appropriate place to ask these questions, feel free to direct me there. I'm obviously not familiar with policy and protocol here, so if I inadvertently step on any toes, I apologize in advance. I am planning to soon make a long-deferred move from Windows to a *nix OS, probably initially Linux Mint. While there have been abundant incentives to make this switch over the years, the proximate inducment is that recent versions of Firefox (with a few privacy add-ins) have become nearly unusable for me. I thought that it might be prudent to first preview one of the minimalist browsers (I do no MM or other such stuff on-line) that is available for both Linux and Windows on the latter, before switching. So I chose Falkon, based on descriptions of its design and intended use. I successfully installed 64-bit Falkon on WIndows 7 Pro 64-bit on 2 different but similarly set-up computers, but received a run-time error: "missing MSVCR120.dll" (part of Windows C++ Redistributable pkg). Several remedies did not fix, so I installed the 32-bit version on one computer (this still failed with same error on the other, for some reason). This version did execute successfully. I was very happy with the appearance and performance of Falkon, and reasonably happy with the function, in browsing most of my usual daily sites. However, I did encounter errors on a few of those, and I wasn't able to find much Falkon troubleshooting help from web searches, hence this post. I did try various combinations of enabling optional page content, and disabling AdBlocker, to no avail. Here are the domains and errors, in the event that anyone here who has been experimenting with this browser can shed any light. Falkon app details are: Application version 3.1.0; QtWebEngine version 5.12.1

bergerrealty.com & atttheshore.com (web cam hosting sites)- "no compatible source was found for this media"

legacy.com (obituary site) - various page loading and display issues. If I fully enable content permissions, I can get the home page displayed, but no links are functional.

facebook.com - Log-in successful. Home page displays, but is immediately followed by: "Qt Qtwebengineprocess has stopped working" here is the pertinent info from the Windows analysis pop-up:

Problem Event Name: APPCRASH; Application Name: QtWebEngineProcess.exe; Application Version: 5.12.1.0; Fault Module Name: Qt5WebEngineCore.dll; Exception Code: c0000005; Exception Offset: 00b75263

I would very much appreciate any pointers to analyzing and resolving these issues you might be able to provide. Thanks.

recent versions of Firefox (with a few privacy add-ins) have become nearly unusable for me.

Due to performance issues? Mind that Linux is likely a good bit more usable on your hardware and you may very well not need to move away from Firefox after all.

“missing MSVCR120.dll” (part of Windows C++ Redistributable pkg)

Not sure, if you're saying that you already found this out, but yeah, there is an installer from Microsoft for this Windows C++ Redistributable package.

bergerrealty.com & attheshore.com (web cam hosting sites)- “no compatible source was found for this media”

I'm on Linux and these work for me in Falkon. But it could be that your particular hardware + the Chrome browser engine that Falkon uses, results in no source being compatible (e.g. your graphics card only offers acceleration for the H.264 codec, which is what Firefox generally uses, not VP9, which is what Chrome/Falkon prefers). Then it would still not work after the switch, although again, Firefox would probably work...

legacy.com (obituary site) - various page loading and display issues. If I fully enable content permissions, I can get the home page displayed, but no links are functional.

Again, works for me. I didn't have to do anything. I have the built-in ad block enabled, but no other customizations, as far as I remember (I only use Falkon as a backup browser).

facebook.com - Log-in successful. Home page displays, but is immediately followed by: “Qt Qtwebengineprocess has stopped working” here is the pertinent info from the Windows analysis pop-up:

Problem Event Name: APPCRASH; Application Name: QtWebEngineProcess.exe; Application Version: 5.12.1.0; Fault Module Name: Qt5WebEngineCore.dll; Exception Code: c0000005; Exception Offset: 00b75263

I don't use Facebook, so can't test this one. This could be due to using the 32-bit version, but it's really difficult to say. Only real pointer I can give you is that "QtWebEngine" is a thin wrapper around the browser engine of Chrome (which is called "Blink"). It's part of the Qt GUI framework that Falkon uses. So, likely not specific to Falkon.

If you've got a spare USB stick, I would recommend just preparing it as the Linux Mint installation medium. You'll be able to boot off of that into a largely functional Linux Mint system, without actually installing it.

This will be slower than a proper installation, as it will read the data off of the USB stick rather than your hard drive, and lots of these "live" installation medias do not come with all the media codecs, so this will probably not be representative for your webcam sites.
I'm also not entirely sure, if you can just install Falkon into that live system.

But at the very least, you can give Firefox a look (it's the default browser), see how that performs, and just play around with the system.
