Insert picture in email text does not work. When attempting to drag/insert picture into email text, the message "The following files couldn't be attached: filename.jpg. Please try again later." appears. Firefox 133.03 64-bit is up to date on Windows 10. I have not been able to find a solution. The dragged/inserted picture always ends up outside the email text box and cannot be moved into it. What is a solution? Is this something new or do I need to reload Firefox?

It worked last Christmas!!! It is not important now that the holiday is over but would like to fix it.

I'm trying to switch firefox dev edition to english

There is no dev-edition version in dnf, snap or flatpack, so i simply installed it by hands (from src i guess). But browser is not in english and i don't know how to switch it back. Everything i found related to "lang" is translations and "preferred language to display pages", there is no "browser lang" or smth

Perhaps i can replace some files somewhere in src?

If I click the cog wheel on a Youtube livestream video in order to change the quality the settings window appears for a second then disappears. It will not stay where it is. It only happens on live streams. Windows 10 Firefox 133.0.3

I recently got a second monitor and I'm experiencing annoying flickering whenever I'm watching a video. It doesn't matter if the video is on my primary or secondary display. They're both the same resolution (1440p), but my main monitor is 165hz while the second is 60hz.

I've read online that disabling hardware acceleration and then re enabling it fixes this. This temporarily works for me and the artifacts disappear. But whenever I restart my PC, the issue returns and I have to disable and re enable hardware acceleration every time. How do I fix this permanently??

Be descriptive. Saying “playing video on YouTube is always choppy” will help us understand the issue better than saying “something is wrong” or “the app is broken”.
