Works well IF you don't have the other application open before you turn it on. To work around that, close the other application, then reopen it. Then ffx will stay on top of that one.

Ich liebe dieses Add-On und möchte es nicht mehr missen! Es funktioniert ohne Probleme und man kann (so wie ich) sogar die PWA-Web-App Fenster anheften. Danke vielmals an den Entwickler! 5 Sterne! <3

pretty good add

простая, но такая удобная штучка

bad

POS doesznt work

Does not work.

Easy to install and works right away!

Good add but doesn't work on some sites

Полная хрень.

Didn't work. AND asked me to go to an outside website to download an extension to make it work. Are you KIDDING? I wish I had noticed the warning about Mozilla not actively screening it for security, I never would have installed it. Now I have uninstalled it, but am worried about what it might have left behind or if my PC now has some kind of spyware etc. :( I should have read the description page more carefully, so it's my own fault, but I trusted Mozilla to NOT allow anything like this to be added to their platform! :(

Only worked when first got it. Couldn't get it on top unless is was made a separate window>shrunk desired stay on page and on top page>dragged them to attached to sides>then open the desired stay on page to full screen>then click on top page and shrink sides down but must maintain its attachment to the side - so is this really STAY ON TOP? Never works. We want to keep a STAY ON TOP tab on top of WHICH-EVER WINDOW OR TAB WE NAVIGATE TO. That's what the name STAY on top INSINUATES. (btw I'm not yelling I'm using caps for clarity of word importance. I don't know why ppl think it means yelling - it would only if it were angry words - duh. ha Is this just a few ppl saying this that is making it hard for the rest of us? really...so prevalent)
Why not make this FEATURE a FIREFOX FEATURE? It's a MAJOR DESIRE/NEED. I don't get how sizing pages and sticking them to the sides is supposed to accomplish this when they don't stay open whenever switching between them anyway. Thanks for hearing me out. Anybody?

Works 25% of the time. Most of the time it somehow turns into Always on Bottom, i.e. it makes other programs stay on top instead of your browser. Some other times it make other windows of your browser stay on top instead of the window you wanna be on top.

I can't be bothered anymore.
