Firefox Support Forum

Hello everybody!

I have to change the resolution ( xrandr --output HDMI-1 --mode 1920x1080) but FF does not resize, please could you look at the image that I have attached?

Thanks in advance!

I've installed firefox in my laptop, and I want to use it in my PC with same bookmark, settings, cookies.. all same

What I have done is: I copy Firefox (whole folder where firefox.exe exist), then apply the profile. It works well, no trouble until now.

But, I have question: is copying whole installed firefox to another PC (without installation) is okay? From security and privacy perspective..

I have installed Firefox on my android phone now that I have installed Firefox browser on my desktop. Trouble is when I run it (on my phone) it very briefly flashes black & white blocks on screen and then makes my phone reboot. I have a Samsung galaxy S4 with android 9.0 (pie) installed. Is there anything I can do to make it work?

W10 and newest update are not compatible. I seek help using Android, because firefox is no longer usable on Windows 10. It started with the tab toolbar using up a large part of the screen and fonts being huge. When I tried to adjust fonts they became too small too read. Dwngrades threaten my profiles, a real low blow. What do I do?

Tonight I noticed something really weird when I tried to reply to a comment on Youtube. Initially, I tried to reply from the bell button in the notifications and soon I realized that the Spacebar was not working. I thought it might be stuck, but it was not, since it was working fine in both the address bar and the search bar. Asynchronous keys function was disabled. Then, I went to the video and tried to reply from there. Guess what! The video was being resized using the shortcuts depending on what I was typing! For example "t" changes between normal and theater mode and "i" makes it picture-in-picture. What is going on? I am sure no key is locked, i even restarted my pc and the same thing kept happening. Then, I turned it off and on and the problem was persisting. Everything works fine on other applications, just YT seems broken for some reason. I tried to type on YouTube on two other browsers and everything worked fine. I don't think it has anything to do with the windows update, since it only happens on firefox, which I don't intend to change. Is there any setting to lock/toggle the Youtube shortcuts on and off? Sorry for the length of my description and thanks a lot in advance!

I wish to know how to fix this issue (magnet links) ? I've installed bittorrent, but not showing on d.a.s page, after refreshing Firefox.

It is possible to screenshot the whole webpage on my friend's window 7 HP laptop by right clicking and selecting screenshot when using firefox,while right clicking does not display screenshot option on other laptops.What is the problem/solution?

Hello, My internet connection Wi-Fi was suddenly off while I was on this website "www.mangago.me", when the Wi-Fi was back on, Firefox gave me a warning that the site in not secured, although I was using it normally minutes ago, I ignored the warning and choosed to visit site anyway, then happened the problem that the site doesn't load anymore, it doesn't work and just load some basic words and figures but it doesn't work, and the lock sign above says that it's "Insecure connection". Also, next to the link address there are some weird letters that seems to be the problem "http://www.mangago.me/?__cf_chl_jschl_tk__=24df23c83a66024051f96aa918da6e486986fe3b-1598272797-0-AeyqkKqzGGRLalXK6AI_heM28f3XtoICyoi6t9Vghtj5RKRMQwNlcf4OgvldTnz8EIok0TqjXSY259YzVr9woOAOFazEKdse_9qu1QNH9S1iJVJeoqwEG6Gjrs8L4b4aKSKCyRtQC4BEfFEJJY6nz7RBVMexFAtbggJ4nG24q7u9VTmq1XhGr04awWCCZSje5gMA9mxprLZGDoMuf-a_3BlpjgyXCCrQHxpDMb6FOJqEx5rOU6f7_YblvLOXKLN91U5MCSn7aYKk5o_R74fJbdM". Although the website used to load without them with clean address like this "www.mangago.me". I tried using other browsers and it loaded the site perfectly,but Firefox doesn't load this site at all. So can u solve this problem for me?

Hi. I use Firefox from many years. Today I was trying to inspect a my web page which looks strange in my Firefox for Android but I just can't. In my desktop I have Firefox 73.0.1 and in my Android phone I have Firefox 68.5.0. If I try to connect I get a message which tells to update Firefox from 68.5 to 71.0 (minimum supported version) but I can't find this version anywhere. I have installed Firefox Nightly for Developer in my phone but now the problem is that the version is too recent... What should I do?

Hello,

I removed firefox from my old android phone installed it on my new one. Strangely, I can see my old device in "Devices & apps" here https://accounts.firefox.com/settings/clients but I can't see any of my old phone's synced tabs. Are they lost? how to recover them ?

Thank you VERY much for the help

I have files on desktop have sent pictures to Firefox. I'm afraid to hook my PC up to Ethernet because I saw it in the files. Networks 26282d. 26282_5g. Qualcomm Atheros AR8152 PCI-E Fast Ethernet Controller (6.30) is on my desktop files. I can access View all Events. I need someone to get files or show me how. I cannot move my cursor off this because tis is the only file I can access. I was in files and when I click on one it turns white can't get access my cursor picks up folder or file and puts it in another place. What can I do?
