Is this issue related to my ancient 15-year-old graphics card, my browser, or something else?

Last but not least, since the screenshot shows the subreddit I moderate, c/kickasswomen, and I don’t want anyone to get the wrong idea: everyone whose content is posted on KickassWomen has given me their permission—I don’t steal anyone’s content nor do I post anything without their consent.

To add some more info, I'm using Debian 12 and Firefox 132.0 (Flatpak version). I used Gnome's Screencast to record the clip but for some reason, I couldn't get the mouse/pointer to show up in the video even though I had "Show Pointer" enabled.

Last but not least, since my username appears on the video and I don't want anyone to get the wrong idea: I moderate a community called c/kickasswomen and everyone whose content is posted on that community has given me their permission—I don't steal anyone's content nor do I post anything without their consent.

My Flatpak Firefox v. 132 freezes regularly especially if I'm on a site with lots of images and videos (like YouTube).

I was told by another user that copying everything from the original profile's directory (profile1) to a newly created profile's directory (profile2) stopped the freezing issues for them:

/home/mario/.var/app/org.mozilla.firefox/cache/mozilla/firefox/profile1/

/home/mario/.var/app/org.mozilla.firefox/cache/mozilla/firefox/profile2/

However, after copying data from profile1's directory to profile2's directory, setting profile2 as the default profile in about:profiles, and restarting Flatpak Firefox, profile2 doesn't load up any of my bookmarks, bookmark folders, passwords, or extensions from profile1—Firefox runs as if it was freshly installed (it guides me through the process of importing bookmarks, passwords, etc.).

How do I resolve this issue?

Edit 1: I think that I may have gotten it to work. I transferred files from:

/home/mario/.var/app/org.mozilla.firefox/.mozilla/firefox/profile1/

to

/home/mario/.var/app/org.mozilla.firefox/.mozilla/firefox/profile2/

And everything seems to be working. I'll test this out and update this post to let you guys know if it really worked or not.

I'm going to use this guide to downgrade Firefox to something around version 127 or below because I did not have this issue with earlier versions of FF.

Btw where does Firefox store crash logs? I typed "about:crashes" in the URL bar but it says that "No crash reports have been submitted". I have also used journalctl to find these errors but I'm not sure how relevant they are:

org.mozilla.firefox.desktop[15004]: Exiting due to channel error.

org.mozilla.firefox.desktop[49355]: [Parent 2, Main Thread] WARNING: g_strv_length: assertion 'str_array != NULL' failed: 'glib warning', file /builds/worker/checkouts/gecko/toolkit/xre/nsSigHandlers.cpp:187

firefox-bin[49355]: g_strv_length: assertion 'str_array != NULL' failed

In case people might get the wrong idea, I only post pics/clips of female martial artists who who have given me their permission. I do not steal content from Instagram.

...it has the same amount of upvotes as one of the posts I made today.

What's the issue here? Why won't the last post show up at or near the top of the page?

I'm using Debian 12, Ryzen 7 5700X processor, and Radeon HD 5450 graphics card. I have tried uninstalling and reinstalling VLC but it didn't resolve the issue. Here's an excerpt from the VLC's log file:

glconv_vaapi_x11 error: vaDeriveImage: operation failed

main error: video output creation failed

main error: failed to create video output

avcodec info: Using G3DVL VDPAU Driver Shared Library version 1.0 for hardware decoding
