Firefox Community Forum

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?

Apparently Firefox updated overnight and now my New Tab Page, which had a ton of tiles on it that I'd pinned over the years is now completely blank, no tiles, no nothing (except the Firefox logo). If there were at least some blank tiles, I'd have something to work with, but when I say blank, that's exactly what I mean.

Is there any way to get back the tiles I had? Because none of the pages I've opened or searched so far has created a tile on the page.

Thanks.

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

i've recently had problems with not being able to login to certain accounts (others are fine) resulting in hanging. other times i might be writing a message (or other) and the browser crashes. can you help me, please?

Websites, even https website, will not load after update to latest version. Cannot even load https://www.duckduck.com. Your support website will not load. Have to use a difference browser than Firefox. Yikes!

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.

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???

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

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 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

Hello, I recently updated to 15.3.2 on a silicon Mac Mini. This morning, both Firefox and TBird ran slowly. I restarted twice and spoke to a Senior Adviser at Apple. The second restart was at her advice, and it brought TBird back to normal performance. She said she believed that the computer was indexing after the update to 15.3.2, which took place last night.

We thought that Firefox was normalized as well, but it is still working slowly compared to Safari. Any suggestions?

Thank you for your help.

What is up with Firefox..? It is slow loading, if it even loads at all.. It will freeze when switching pages. It takes forever to load after PC restart.. Then it takes forever to load pages.. Seems like the more it updates the worst off it gets..

Man I'm so sick of this now. Youtube videos become unwatchable on firefox, I really hate chromium browsers and dont want to switch but this is so annoying. When will firefox fix this?

For the last several days, Firefox has become nearly unusable. It started using an excessive number of processes. Then I started getting very frequent hanging and "Mozilla Firefox (not responding). It may freeze for several minutes, and often I have to shut down and restart my PC. It then takes much longer than usual to shut down, and after restarting, it takes several tries to get Firefox to open. A couple days ago, I updated Firefox to the new version for Windows 7 Vista, and it may have actually gotten worse.

It took me about 25 minutes to type this short description of the problem because it froze several times.

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
