Firefox 技術支援討論區

I am researching memory management in software applications and would like to know how Mozilla.org addresses memory leaks in its products, such as Firefox. Specifically, I am interested in:

Detection Methods: What tools and techniques does Mozilla.org use to detect memory leaks during and after development? Common Sources: What are the typical sources of memory leaks in Mozilla's products? Mitigation Strategies: How does Mozilla.org fix identified memory leaks? Monitoring and Analysis: How does Mozilla.org monitor its software for memory leaks post-release? Performance Impact: What has been the impact of memory leaks on Mozilla's product performance, and are there notable case studies? Community Involvement: How does Mozilla.org involve its open-source community in identifying and fixing memory leaks? Documentation and Training: What resources does Mozilla.org provide to educate developers about preventing and resolving memory leaks? Visit here for further details Detailed insights, references, or examples would be greatly appreciated.

Website loaded without any problems for months until I get this error message out of the blue; see screenshot below.

Did try Java toggle on-off extension but the options button is not displayed on the extension that would have enabled me to enter URL of site in blacklist text box.

When ever I play a game, the video I have playing (yes I need that stimulation) all of a sudden just freezes I can hear the audio but the video just freezes unless I click back onto the browser

Mein Laptop reagiert nicht, wenn ich mich über lockout abmelden will. Mir wird stets die Seite "Fehler: Gesicherte Verbindung Fehlgeschlagen." und nicht wie vormals beim öffnen des Laptops. Wo liegt der Fehler?

I'm a long time FF user, the developer edition is my preferred browser. It suddenly started crashing, a complete removal and new install did not help.I posted a help question a couple of weeks ago but no workable solution surfaced unfortunately. I assume the problem is still the same.

ps. I'm currently using the standard FF verison and it runs smooth as ever....

The most recent crash report:

I am trying to open a website but I keep getting error code 522. I've tried using Chrome and it connects to the website with no problem. I've checked my privacy settings and I do not have that website blocked. What else can I check? I don't think it's an issue from the website side. If you want to check then check here : https://jewelcars.co.uk/

For the last few weeks i've noticed youtube vids buffer but then sometimes stop and when the video reaches that point on the bar it skips about 5-10 seconds, then contines to buffer like normal, so I have to use the arrow keys to go back to see what I missed. It is very annoying. Happens almost 1-2 every day at random times. My wifi speed is good. I've cleared cookies and caches, turned off enhanced tracking protection for youtube, i've even increased perfomance settings for intel graphics in my pc's power manegment plan. Nothing! Can anyone help, thanks.

Keep getting this response from browser or bank log-in site: "You were signed out due to inactivity, but you can log in again whenever you’re ready."

Upgrade my desktop Firefox browser to version 126.0.1 a few days ago.

Since then, I'm having all kinds of probs logging in to social media sites.

The biggest prob is with X. I've tried to inquire about this situation with X support. I'm being told that my account is good and I should not be having log-in probs. When I explain that I'm being given an authentication challenge that is not allowing me in - despite the fact that the challenge is cleared - I'm told that I should consider my browser privacy settings.

Nothing has changed with this since my last log-ins except the upgrade for Firefox.

Please advise regarding this inquiry: is there something new in the privacy issues with this new upgrade? And how can this issue be resolved?

I've attached three screenshots to illustrate the prob.

Thanks.

Every time I attempt to download a file today, no matter what it is or where it's from, it pops up saying that the download failed immediately. I can download through Edge or other browsers, just not Firefox (or any Firefox offshoots like LibreWolf). Not sure what's causing it, I've run a whole gambit of troubleshooting options, including:

• Checking my connection
• Checking my drive's space (plenty)
• Changing the download path
• Reset the download folder in about:config
• Rebooting my computer
• Clearing my downloads
• Trying a new profile
• Run a MalwareBytes scan
• Closed MalwareBytes and turned off my firewall
• Ensured OneDrive is disabled
• Refreshed Firefox
• Did a clean install

Nothing works. The only thing I found that gives me any kind of clue is this error message in my about:support: ""NotAllowedError: Could not create unique file in `C:\Users\[my name redacted]\AppData\Local\Temp' (NS_ERROR_FILE_ACCESS_DENIED"" It seems like Firefox is trying to write to Temp and can't get the permissions, but I'm not sure why that would be or how to fix it. I have tried googling my butt off, but I'm not finding anything helpful - I may just be blind.

If anyone has any idea how to fix this, it'd be much appreciated!

i updated my browser and now everything is gone, my extentions wont open as its in "safe mode", none of my browsing history is saved anymore. should I delete firefox and reinstall it?

When i scroll up and down on a page, it instead provides the back-page instead of scrolling up and down on the website. this is for all websites. the scroll function works oroperly in system settings, it is only with firefox. autoscrolling is enabled in settings.

Dear Firefox support community

Greetings from southern Germany, near Lake Constance :-)

I have issues since a few months that Firefox loads website only when I actively click on the app and put in foreground. Then the tabs start loading. Why is that?

After startup of Windows 10, I usually run a little batch script of mine starting various applications such as Outlook, Notepad++ etc, including Firefox along with my favourite websites, just like this:

start "" "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Firefox.lnk" https://de.wikipedia.org https://www.google.de [and more...]

So Firefox loads and opens all the tabs in the background, while other apps such as Outlook or Notepad++ come in the foreground. I read mails etc. before I decide to check e.g. Wikipedia. So it might take 5 minutes after Firefox got opened before I actively put it in the foreground. THEN I see no websites got loaded, and THEN Firefox starts to load the websites, which then takes the normal amount of time of a few seconds.

I wonder why Firefox does not load all my requested websites directly after start in the background.

An annoying side effect is, when still in Outlook and clicking on a website link in an email, it won't open in Firefox, most likely due to that reason that Firefox still waits for all the other websites to load. I need to put it into foreground, wait for the loading process to complete, and then go back to the email and click on the link again.

Any ideas would be greatly appreciated!

Many thanks in advance for your assistance & Best regards Volker

Hi, I've recently downloaded firefox and trying to add extensions that were similar to the ones I used on chrome. My problem is that all the extensions (Hoverzoom, Short Keys) in the extensions tab in the toolbar and appear to not be working (both in private and normal browsing). However the extensions (Ublock, SponsorBlock) that have their own icon on the toolbar seem to be working fine.

I've attached a reference image,

Any help would be greatly appreciated.

I changed the 'mousewheel.with_shift.action' to a '5' in 'about:config' to be able to use pinch zoom on my desktop with a keyboard and mouse, like I'm able to do on my phone or laptop with a touch screen. This does work properly and I'm able to pinch zoom by holding down the Shift key and scrolling my mouse wheel up and down.

However, there is an issue of sensitivity. The pinch zoom is painfully slow, and I have been unable to adjust its speed. If there exists an option to change the pinch zoom sensitivity, I'd greatly appreciate the help.
