Diễn đàn hỗ trợ Firefox

Hello!

I would be very grateful if you could help me figure it out, the browser suddenly stopped working, does not open any tabs, just a blank screen, does not open settings, some buttons simply do not respond at all. I cleaned the SScleaner yesterday, but I did not select anything special there, it was a basic regular cleaning that the program offers.

How do I fix this? reinstalling does not help, the browser still does not work

Hi all,

I would like to know if this color issue is expected behavior or a bug somewhere on my system.

I am using a monitor (Acer ET322QK wmiipx) which displays color at a depth of 10 bits per channel (for a total of 30-bit color depth). When viewing images which have color depth exceeding 8 bits per channel, color banding is visible in Firefox that does not appear in GNOME Image Viewer, indicating that the image is not being displayed at the correct color depth. I've attached an image with 16 bits per channel color depth as an example. This sphere render is deliberately dim to make color banding more obvious. It should look smooth/unbanded on a display with support for colors with greater than 8 bits per channel.

By opening the Firefox console with Ctrl+Shift+K and entering "screen.colorDepth", I have confirmed that the display is identified by Firefox as having 24-bit color depth.

What is going on with firefox, are is it being even more dminished now by microsoft and google? since some update, i cant watch even a youtube video due to the length of time it takes with buffering and loading , and my university LMS pages arent loading and trying to download a pdf from researchgate not even working.

embedded apps like padlet dont seem to be working either

I have flushed out cookies and caches and restarted many times - still the same issues, I went in to troubleshoot mode and still the same issues.

If i try Microsoft Edge it seems things are working fine, and if i access firefox using a VPN (i am in australa, but i set it to a country in europe) then firefox works fine -- what is going on?

please fix this

After letting Firefox idle for a bit (like 5 seconds) and nothing playing on the screen, when I come back, it causes screen stuttering for my whole desktop. Disabling hardware hardware acceleration doesn't help much.

OS: Arch Linux x86_64 Kernel: Linux 6.14.5-arch1-1 Display (CMN1521): 1920x1080 @ 144 Hz in 15" [Built-in] WM: Hyprland 0.49.0 (Wayland) CPU: 12th Gen Intel(R) Core(TM) i7-12700H (20) @ 4.70 GHz GPU: NVIDIA GeForce RTX 3050 Mobile [Discrete]

I have been getting the following message several times: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window. Close Firefox" I check my programs and I am only running the current version on Windows 10 Pro. Why do I get this message?

Firefox was working normal, but the next day the program stopped working. Only changes was a security update from Microsoft Security.

If I click the Firefox icon, nothing happens, If i click to open Firefox as an admin, I get an nearly empty window for Firefox (Image added).

I have totally uninstalled Firefox (with the folder "Old Firefox Data"), and reinstalled Firefox, but to no avail !!!

Any solutions ???

Regards

I have been experiencing a lot of lagging, lockups and closure when browsing. I use Windows Version 10.0.26100 Build 26100. My Firefox version is 138.0.3 (64-bit). While telling you about this issue, my systems has locked up. I had to wait for it to start again. I have had to use other browsers, Google Chrome and Edge to complete tasks. I am able to browse and do everything fluidly, without issue using those browsers.

I have noticed that certain website just do not work well with Firefox. I'm wondering why that is? For instance, Petsmart.Com. That's a popular website. I almost always have to complete my orders using a different browser. Is there anything that I can do about this? I'm really frustrated and getting ready to ditch Firefox.

Thanks for any help you can provide.

Why after the most recent update to version 139.0.4 64bit does any Google search result page on Firefox now use 110% cpu according to about:processes? This isn't the first time a Firefox update has caused this to happen on my computer either. It causes extreme system lag until I'm able to close the Google search result page in Firefox, then everything returns to operating normally. In the past subsequent Firefox updates have resolved the issue but it can sometimes be a while before the next update is released and that one is not always the one that fixes it. Is there something I can do resolve this without having to wait for future updates to be released?

Hi, strange things happening with Firefox of late. Eg, when trying to log in my mail on o2.pl with saved login/password, now the log in page loads and doesn't show the saved login, doesn't allow me to click in any box either (it previously did it flawlessly). When googling images, it only shows some images and when I scroll down it doesn't show more. Some pages won't load properly. "Content failed to load" on chatgpt. And miscellaneous other glitches on other websites. I have some tabs opened, I want to keep them, don't want to reset Firefox. The problems only appeared with recent updates. What to do? Best. W.

firefox 138.0.1 is eating up memory, specifically;

-contentproc -isforbrowser -prefshandle

theres over 20 of them requiring 200mb each

please tell me how to turn this off

thx

You guys do an update. Suddenly I can't open any sites. Top of the tab, a little set of dots go side to side foreverrrrrr. Do not, I repeat, do not ask me, "are you doing this, or are you doing that"......that's not a solution.

It's bad enough I have to use another browser to read FOX NEWS, cause your page refreshes non-stop.....

Oh and I used clear history, and my sites all want me to relog back in. Again, do not tell me to unclick cookies and stuff....

When using the browser, my monitor starts to "blink". To be more precise, it just pops up a black screen for a second or two. I use both monitors and both go off, the cursor remains. There was no such thing before using the browser, but Firefox remains the only sensible browser, so I don't want to change it to something else. I've tried turning off hardware acceleration, but it doesn't help.

I use Pocket on my MacBook Air 2017 MACOS Monterey 12.7.6, and used it daily for years. I cannot access Pocket just now so cannot give you any data about its version. Below is a screenshot of the Firefox version that I just loaded yesterday but which is also refusing to load any link, incl. Pocket. No error message now; yesterday when Firefox refused to load anything, a message saying "Not Secure" showed up atop my screen left of the link I was attempting; it showed up for every link I tried, but is no longer showing up at all, though Firefox continues to be unable to load any link. Second screenshot below is my current attempt to load 2 links plus Pocket, a video of it would show all 3 loading attempts on the screenshot having the little dot moving back and forth side-to-side but never loading. Hope this helps! And thank you kindly for assisting me, Alasdair Coyne

I'm debugging some web sites, and I often need to reload a page to see if a change I made on the server works correctly. On iPads and Android devices, this doesn't seem possible. Yes, there are the circular-arrow buttons, but they only work with Firefox (and Chrome;-) on my MacOS or my linux server, but not on my iPads or Android gadgets. They act like they're doing something, but the page on their screen doesn't change. (With FF or Chrome on the "real" computers, it does change). The only advice I find online is to use CTL-R or something similar but those "devices" don't have CTL buttons. Nothing else I guess at works, either.

When I ask online, I get replies that work for linux, MacOS or Windows, but clearly saying "iPad or Android doesn't help; the answers don't apply to those systems.

Am I missing something? Web developers need ways debug their code or html or whatever they're working on, and this requires checking how it works on the actual users' screens.

Today Firefox crashed twice and a Tab crashed once! What's going on with Firefox? It's especially disurbing to have it crash during a long video and then you have to find where you left off.

Firefox is running too many processes in the background. You have eliminated access to the user settings to be able to reduce that number. It is using so much memory (two tabs, one window, 1400 MB) it is becoming a nuisance rather than an asset. How do I reduce the number of processes. Thanks

I get a message "We Encountered an Error" Please restart your application to try again. It continues to pop up (only when I'm in Firefox) and I click the button "close" and can continue until it pops up again. This just started today. Is there anyway to get this to stop?

When clicking a link in Thunderbird the required page no longer opens. I just get a message window "Close Forefox". See attachment. I have checked my settings and I have "Open links in tabs instead of new windows" checked so I why is Firefox trying to open a new window and why does it have to close the existing window. Time to move to another browser???
