Firefox Community Forum

I use two Firefox windows: one that has the web interface of my music player only, and another window for other internet browsing.

However, sometimes when I open a link from outside Firefox it opens in the window of the music player rather than in my "browsing" window. Moreover, when I switch to Firefox (using Cmd+tab on MacOS), the music window is selected rather than my "browsing" window, even if the last selected window was my browsing one.

Is there a way to make a window exclusive for a tab so that no other tabs are open in that particular window (and perhaps the tab bar is hidden)? Or is there to designate one of the windows as the "main" window?

Mozilla tab keeps crashing (especially at YouTube) I was wondering if someone can help me find out why!

like tell me how to show the log or something to identify what is doing the crash.

Thank you in advance!

An unwanted bookmarks toolbar appears above the URL field, as shown in the image.

After all the bookmark shortcuts it contains are closed, and FF is restarted, the marks reappear.

How can they be purged permanently?

I recently graduated from Seton Hall University earlier this year, and released the laptop they gave me from their system to where I am the sole owner of it. I just converted to Firefox & Thunderbird, but for some reason Firefox automatically opens the Seton Hall website when I open Firefox. Microsoft Edge never did this, but I really don't to switch back to Edge. Does anyone know how I can stop Firefox from automatically opening the home page for my former school?

Pinned tabs disappear from main browser window AFTER using "New private window" browser to test a different site issue. This has happened a few times for me. It is very cumbersome and should not be necessary to do a problem search and see all the steps needed to follow using the sessionstore.jsonlz4 process. Why can't Firefox have simple "restore PINNED tabs" history? I am going to plan on saving each link for each pinned tab in a document of my own simply because it is EXTREMELY annoying and TIME CONSUMING to try to get each of them back. Why does the "New Private Window" use cause this issue in the main browser window?

I have a pinned tab (from Distill Monitoring addon) that always has to be pinned. And thats ok. But the problem is that every few minutes, new duplicate pinned tabs emerge so that around 5 or 8 of them emerge. I only want one pinned tab open, not several duplicate pinned tabs. How do I fix this with CSS or other means?
