Firefox Support Forum

Hello. I recently moved from windows to Linux Mint, and noticed the behavior of the Picture in Picture window is different when resizing. On windows, the aspect ratio is kept. while on Linux, it is free form, making these black bars around the video, so I have to resize it very carefully to not show any black bars.

How can I make the PiP on Linux behave like on Windows? That means resizing keeping the aspect ratio.

Attached are the comparisons between Windows and Linux Mint.

Thank you very much!

Is it possible to permanently set a different search engine for private browsing? I have Google set as my search engine in my normal browsing mode, but I'd like the private browser search engine to be permanently set to DuckDuckGo.

(I realise I can manually set it each time to DuckDuckGo but this is tedious.)

With thanks.

My firefox installation always run in English with all of its interface elements being in English. One of the recent updates introduced a weird behavior - some of the UI became Russian. I seem to have fixed/bypassed the issue last time it happened https://support.mozilla.org/en-US/questions/1415337 but nothing works this time.

Most of my firefox is in English, but some elements such as tab titles in devtools, browser popups "do you want to leave this page", tooltips in this very text form where I'm typing right now - are in Russian for no apparent reason.

I have another profile on this firefox installation and it's completely in English as intended. I tried to check for what changed in about:config, looking for "language" or "locale" string, and there's nothing that stands out. I've tried clearing startup cache, switching language back and forth, restarting firefox.

Any suggestions?

Any extensions I install suddenly don't show up in my toolbar or the customization menu anymore, so I also can't drag them there manually.

Deleting the extensions and re-installing them didn't work, neither did deleting the extensions folder itself.

Does anyone know how I can fix this? I've attached a screenshot of the customization menu and extensions menu below.

Thanks :)
