Firefox 技術支援討論區

Every few hours, maybe 4 times a day, XULRunner appears and tabs me out of everything. It says "This profile was last used with a newer version of this application. Please create a new profile."

There isn't a 'create new profile' button. I already made a new profile as well, but it did not fix the problem.

I recently changed to the newest ESR, 115.10.0esr, to fix streaming issues.

Out of nowhere, my cursor speed in Firefox has slowed to a truly unusable crawl. I refreshed a page and it was suddenly inching along at worse than a snail's pace. I'm using a USB trackball mouse. This is only affecting Firefox; no other applications have this issue. Using Windows 10.

Here's what I've tried so far:

• Restart Firefox
• Started Firefox in Safe Mode
• Restart computer
• Create a new profile in Firefox
• Check my mouse's firmware
• Try a different mouse

There was another question about this years ago, but the accepted answer about accidentally enabling a Windows accessibility feature doesn't say which feature it is or how to disable it (if that's indeed the case). The link also seems to redirect to a generic accessibility page.

In recent attempts to join a few webinars I am now getting more and more "TLS Errors." I have noticed that many of the solutions to this problem involve actions that do not solve the problem but create larger issues. Do you have a solution that works safely? I am forced to use Windows 7 unfortunately due to work systems and a long story. I think this is my primary problem but I have to keep using it until the bitter end with this PC.

I appreciate your kind help. Thanks, Clay

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

Greetings everyone,

I've had this problem for a while and I don't know what to do.

I had a problem where Firefox kept crashing before it had finished loading up all of my former tabs and windows and so I was given the option of opening Firefox in "Safe mode" which I did, but now Firefox only starts in "Safe mode"...

I'm running the most up to date version of Firefox.

Thank you for any help!

When I run firefox on WSL2, buttons dont work on any pop up windows. Foe example when installing a firefox extention - it will download and pop up a small window at the top right to add the extentionto firefox. The buttons dont work. Another example is when opening up the firefox menu bar (hamburger bar) - it will pup up a small window to allow to open up settings, go to add ons, open bookmarks or history. The buttons dont work. Last example is the pop up window for this Ash your question page for firefox support - When clicking "Which topic best described your question - it will pop up a small window to select what type of question Im gonna ask. The buttons dont work.

I dont know how to fix this. I restarted, deleted my firefox profile, started of safe mode, nothing worked. How do I solve this issue?

1. Web pages load in gibberish, they aren't legible. 2. Web pages load with neon green blocks. 3. Firefox isn't allowing me to download an entirely new download.

I understand the gibberish could be a font problem but when I use right click for inspection options, I can't find any font info anywhere. Even if I could, what would I do then? Green blocks, have no idea. I used to use Firefox and have just now started again but would prefer a brand clean copy. Mozilla isn't giving me that option. Thanks.

Even after numerous Uninstalls and a Reinstalls I keep getting this error notice when trying to open Firefox...

The application was unable to start correctly (0xc0000022)

Hello :) Since one of the 2022 Firefox updates, I am constantly experiencing font rendering issues when the hardware acceleration is enabled. It occurs after a while of browsing on all websites, regardless of font family. See the attached screenshots.

Windows 11 Pro (upgraded from 10 where the problem also occured), GeForce GTX 1070Ti, 2x 4k monitor.

I reinstalled nVidia drivers from scratch, cleared the Firefox data, even experimented a bit with Direct2D settings in about:config; disabling the extensions (ABP, Simple Tab Groups) does not help either. The problem disappears completely when the hardware acceleration is off, but obviously I would like to have it on (for Google Maps, Twitch, hi-res videos, etc.)

I've always loved Firefox and still do. How do I make it love me back? ((-;

Hi there, I have noticed that my Win11 Asus laptop is always short on RAM (16GB available), with Firefox taking up a significant amount even with only a few tabs open.

As you can see by the attached image, when I go to 'about:processes' it shows that GPU processes alone are taking up nearly 1GB of memory, with the only tab running being the 'about' page. I only have 6 extensions (uBlock Origin, Zotero, Containers etc) none of which are meant to be RAM intensive.

What are these GPU processes that are running, and how can I reduce the memory used by them?

Thank you.

looks like a problem with Firefox as no problem when using a different browser e.g. Opera. Also cannot log onto Nextdoor.co.uk using Facebook to log on. Again works fine on Opera

Any links from rcsearch.ru to aliexpress is broken in firefox, but works in another browsers. For example click any aliexpress link here rcsearch.ru/-c48920.

Whenever I go to youtube, it fails to work and leaves an error in the console similar to

Uncaught Error: Constructing ytd-app: [Exception... "File error: Corrupted" nsresult: "0x8052000b (NS_ERROR_FILE_CORRUPTED)" location: "JS frame :: https://www.youtube.com/s/desktop/050e6796/jsbin/desktop_polymer_enable_poly_si.vflset/desktop_polymer_enable_poly_si.js :: kCb :: line 9877" data: no]

I've determined that I can fix the problem by deleting my Firefox profile. I'd prefer to avoid this since there's a lot of useful history there. Is there a more targeted fix the problem I'm seeing?

Hi,

Occasionally when downloading files on Firefox, they'll freeze completely (often at the very end.) There is no way to pause or cancel the downloads, except to restart Firefox.

When I attempt to restart Firefox, it closes the browser window. However, when I try to reopen it, I get an error message stating that Firefox is running but not responding. The 'Close Firefox' option does nothing, except make the box pop back up a moment later.

I can't kill the Firefox process in Task Manager or Process Explorer, because it says access is denied. I can't kill it using taskkill in command prompt because it says there is no running instance of the task.

The ONLY thing that seems to help is completely restarting the computer, which is getting frustrating to do several times a day.

I can confirm Firefox is up-to-date. Any tips are appreciated, thank you!

Running Firefox 125.0.1 on MacOS 14.2.1, all audio input is very quiet for all applications, not just Firefox.

Experiments I ran:

• people can barely hear me in Google Meets
• microphone works great in Quicktime (making a recording) when Firefox is running but not receiving audio input
• microphone is very quiet in Quicktime when running a Google Meet in Firefox
• microphone is very quiet in Quicktime when running a discord voice channel in Firefox
• microphone works great in Quicktime when running Google Meet in Chrome

This started maybe ~3 months ago for me. I'd love to see a fix, since Firefox is my favorite browser in most other ways - otherwise I'll have to give up and switch to Chrome at long last :'(
