Diễn đàn hỗ trợ Firefox

For a while now firefox has been unable to enter fullscreen when pressing F11. Instead all it does is move the "Scroll forwards", "Open a new tab", and "List all tabs" button over slightly (The buttons on the top right, next to the minimize and close buttons).

I don't know what's going on with firefox.

Firefox Version 142.0.1 (64-bit)

when I go to icloud.com to view and download photos and all my icloud stuff on my phone, I can no longer sign in using firefox. I turned off the shield security but no help. There used to be a pop-up that let you enter the code apple emailed you so you could access your icloud stuff on the web. Now there is no place to enter the code they send you. I enabled pop-ups too, but that didn't work. Help! I need my photos! And I use that site pretty much constantly-

Have been having an issue for the past month or two where if left in the background firefox will slowly start to eat up my available ram. I was using it like this perfectly fine for years previous to now.

I dont have this issue when I'm actively using it, only when I tab away from it and specifically its not on screen. Once I tab back to firefox the ram usage immediately dips back down to normal. I have tried many things to try and solve this like doing a clean install of firefox, getting rid of extensions, clearing my browser cache, closing all other apps to verify it was just firefox, clearing my history, turning on hardware acceleration. Nothing seems to help, im really at a loss and I don't understand what changed besides it being updated in the past couple of months.

My computer is fairly heavy duty and I have 16gb of ddr4 ram that again was working perfectly fine to run firefox before these past couple of months. As a result of this issue however if left in the background for too long on accident firefox uses up all my idle ram and starts causing other programs to not be able to run and has even crashed my computer previously when trying to run a program like clip studio paint.

I have noticed that while running the firefox task manager there is definitely some difference in memory usage when i tab back in after letting it be in the background so I have attached screenshots of the regular usage while tabbed in and the captured usage when i tab back in.

Any possible solution is welcome because I really enjoy using firefox and i dont want to have to switch browsers unless absolutely necessary.

Windows 11. I have my taskbar behaviour set to ‘Automatically hide the Taskbar’ So usually the Taskbar is not displayed, but when I move my cursor to the bottom of the screen it reappears. With Firefox I cannot make the Taskbar reappear.

I am unable to sign into the iCloud web page on Firefox. I can sign in on Microsoft Edge, or on the Safari browser on my phone, so this is clearly a Firefox specific problem. When I try to sign in, the page skips the option that verifies my identity and goes straight to a message saying "Failed to verify your identity, Try again" without allowing the verification to occur. The verification would occur if the page would allow it to, as it does in the other browsers I mentioned. This was working fine last time I logged in a few days ago, so this is a new problem. I could switch over to Edge, but would prefer to use Firefox, if I can. Please help me. Thank you.

I was on the ESR channel and after the recent updates to 142.01 or 141 the ESR is missing from the about Firefox. I had got the tab groups option a few updates back and liked it. This latest update changed how a tab group collapses, instead of showing only the tab group name and collapsing all the tabs it leaves one open wasting space when I have several other tabs open. At least I don't see any sign of the annoying AI junk getting in the way yet. I thought you had a choice to stay on the ESR channel according to this link and others. https://support.mozilla.org/en-US/kb/firefox-support-windows-10-end-support I'll probably be forced to update to Windows 11 to do my taxes next year but I thought at least I could stay on the ESR channel to avoid new features getting in the way.

Since upgrading to Windows 10, I can only access my Yahoo email using Microsoft Edge. When I try to access in Firefox or Google Chrome, my access is denied. I've tried clearing cookies, browser history, rebooting my router, etc. Any ideas I can try?

For my Canvas courses, where there should be embedded videos, nothing shows up. However, the videos do appear on both chrome and microsoft edge. I have tried disabling UBlock origin on Canvas and it makes no difference. Attached are screenshots of what I see in Firefox (no video) vs Edge (video).

Hello, I am no longer able to sign into my Apple iCloud account and tools (Mail, Calendar, Notes, etc) through my Firefox browser. The problem started this past Friday, and it happening on both my home office and work laptops. When I switch to my Microsoft Edge browser on the same 2 laptops, I am able to sign-in to my iCloud account and tools without any difficulty. So it is not a problem on the Apple iCloud side. I am able to access my iCloud account and tools/apps from my iPhone and my iPad as always. It is only when I try to login from a Firefox browser window that I get a "Failed to Verify Your Identity" error message.

When I use the search engine it will not open and says "Hmm we're having trouble finding that site". My Bookmarks all work and open fine but i cannot search anything?

I can't find the adjustment for my screen size. It's overrunning all the edges of my monitor making it impossible to see my panel on top and bottom. Is it in my computer or is it firefox?

Hello:

I am trying to create a csv file of my passwords to import to Microsoft Edge from FF. I went through these steps in Firefox:

Settings>General>Import>Select Passwords from CSV...

...and then it takes me to browse my computer for a CSV file that I have YET to create. I don't think this is how you create such a file.

I'm not sure how to import my passwords to create a CSV file so I can put them into MS Edge. When I tried importing my password (and all my other data) inside of Edge via Edge, it only brought in 235 passwords from Firefox where I have 422. So I would assume if I used and imported my passwords to Edge via a CSV file instead that all my passwords would populate in Edge not roughly half of them.

Could you please tell me how to create a password CSV file in Firefox to use in Edge?

Many thanks in adabce
