Diễn đàn hỗ trợ Firefox

Firefox opens full screen on my main monitor, one of three, but not the last-opened and before resizing to its last-used location and size. This three-stage process happens in a instant, interfering with live activity on my main monitor besides being really annoying. Hasn't always behaved this way. Any suggestions?

Thanks, Mike

Firefox 144.0 64 bit

I've been using what I gather is an "older" profiles system via about:profiles.

Now if I:

1. go to about:profiles and open my second profile in another window, 2. close second window and about:profiles page, 3. open about:profiles again in first window,

I get "Another copy of Firefox has made changes to profiles. You must restart Firefox before making more changes."

This happens every single time, even though I've made zero changes to profiles, and is extremely annoying.

Can/should I migrate my profiles to the new profile manager? How to do this?

I don't know if this is the proper topic, but I'm not sure what to call it. For the longest time I've had an issue with the settings being reset every time I open the browser - all my add-ons are off, all my configurations return to the original state, every single time. I have to manually turn them on all over again every time. Does anybody else has the same issue? Can it be solved somehow? Do I need to redownload Firefox or something?

I had to get a replacement keyboard,and it worked for a while , And then about a week ago, no volume on you tube,google ,but i have audio on mirosoft edge. Checked volume setting's over several times. An advisor told me ,that the logitech keyboard maker,installed optional driver's , that could have caused this? I searched device manager ,to uninstall but didn't find it?

I have a chromebook with linux enabled and installed firefox according to mozilla's instruction - via the sudo get-apt command. The cursor changes from the default to a very small adwaita. I've spent hours googling this issue and everyone I've come across had used some third party repo or was trying to shove in their own custom cursor theme. Literally all I want is my regular cursor back, and I have no clue why mozilla would have a specifically set cursor for their browser instead of just having it default to os. I don't really know what I'm doing here, but I cannot begin to state how tired I am of messing with this dead-end issue.

How can i talk to tech support? unable to share screen on both zoom and ms teams. also, limited function within browswer and zero access to both ms teams and zoom via application outside browser. per endnote tech support, the problem with either apple or firefox. i need to go through the process of elimination where is the problem originating.

I opened my computer several days ago. Firefox updated itself sometime recently while my laptop was closed. Once I opened it, it made me create a profile to continue. Now ALL of my history is deleted. All of my windows and tabs are gone. There is no history beyond the profile it made me create to continue using it. Is there any way to get back the previous history? This is about enough to make me give up on firefox completely.

I am on a Windows 11 machine. Lastpass extension for the Firefox browser does not maintain my vault data. I have to refresh each time I go into the browser. This just started a couple of days ago. Perhaps after installing a new Tmobile gateway? Ideas on how to address/fix?
