SUMMARY Firefox provides a tool, that offers automatic tab unloading. Due that, I had 700 tabs open, before I switched to Falkon. All worked fine. In Falkon, my desktop machine freeze at ~ 20 STEPS TO REPRODUCE 1. Implement a mechanism that automatically unloads unused tabs. OBSERVED RESULT Freezing computer EXPECTED RESULT love this one: https://addons.mozilla.org/en-US/firefox/addon/auto-tab-discard/ SOFTWARE/OS VERSIONS KaOS KDE Plasma Version: 5.14.4 KDE Frameworks Version: 5.53.0 Qt Version: 5.12.0
Hello, I put together a simple prototype (Python extension) https://www.pling.com/p/1307514/ To report an issue with it please use GitHub: https://github.com/SGOrava/Unloader
@Juraj I've tried your extension (Unloader) on my bleeding-edge compiled Falkon 3.1.0 (65259cb0), and it crashed my browser. The extension was installed through the Install link with ocs-url. BTW, in general, it would be nice if Falkon respected Ctrl+Tab behaviour for the last tab, but it's the subject for another ticket.
Hello, Thank you for your report. Can you be more precise about the crash? What Falkon version did you use? (Check in Menu > Help > About Falkon > Application version) Was there any message or it just crashed ? It is working fine for me here, no crash what so ever, so I would be grateful for a feedback. The problem can also be caused by broken python support on your side, check if other python extensions can run (Run Action, Hello Python) PS: > on my bleeding-edge compiled Falkon 3.1.0 (65259cb0) Sorry, I am unable to find commit with such id I also use use development version: Application version 3.1.99 (fbf7f956)
Hi, Juraj, Mine was rather the (unhelpful) ID of my local merge commit, sorry. It was shown in 'About'… You reply gives me a hope, that a number of thing might, actually, work. Among which are also non-working 'Actions', and python[3] plugins giving me strange b'b'' -encodings (YouTube and friends). I had very limited time to investigate those. I've compiled Falkon with IntelMKL and -O3 -mtune-native optimization. Running Falkon crash through gdb it gives me only (srry for possibly unhelpful a long listing): ─── Output/messages ─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── libpng warning: iCCP: known incorrect sRGB profile Thread 1 "falkon" received signal SIGSEGV, Segmentation fault.
