Firefox 技術支援討論區

Only one Browser has problems with HD videos (1080p + above) on youtube: Firefox in the most current version.

I have tested so far only the one current latest version of the ESR branch (78.3.x). But as visible from thousands of articles to this very particular problem (when i search the community help database for "Youtube videos stutter" i get multiple thousands of entries - i read only a handful of them to realize that they are all "closed" and not a single one "solved"), this problem persists since multiple years now.

I have a very old PC by my side with a very old Firefox (benchmark wise slower than my current PC by a factor of at least 3) ESR 52.9, which is able to play the same videos in the same HD resolution without the slightest stutter.

The drivers on that old system are - naturally - outdated by half a decade. THAT OLD OUTDATED system with THAT OLD OUTDATED Firefox is well able to play even multiple HD videos side by side. With-OUT any stutter.

Thus, you can easily deduce by logical reasoning that nighter any outdating of drivers whatsoever nor any outdating of anything else on the system, be it hardware wise or software wise, CAN AT ALL be the culprit of that stuttering.

While the former holds true, what you actually find in the communities help are completely useless and irrational tips of "upgrading the browser to the last version", "upgrading drivers" or "reinstalling any software" or the like.

Let me be clear: Nothing of the latter will ever help in overcoming the stuttering of current firefoxes at all. The only one measure that will help here is to revise the code that is underlying the video pipe.

Since the stuttering regularly only begins after about one to two minutes into the videos, it is strongly suggestive that something in the memory management - probably in the way resources becoming freed after use - is accumulating over time until the stuttering begins. Badly managed garbage collection, perhaps?

***************************** The problem When I start firefox I see a blank page (this was not my starting page before the problem occured)(Image linked).

The overall graphical window is not frozen but I can't open any webpage nor any local file. The option pages don't work either nor any of the about:XXX pages.

*************************** What I tired I cleared my cookie/cache. I tried firefox's safe mode. I refreshed firefox. I deleted my profile and created a new profile. I desactivated all my security software. I ran firefox with root privilege. Updated windows. None of that did solved the problem.

This problem persisted after I haved uninstalled Firefox, deleted my profile, deleted all mozilla directories in ProgramData, AppData, Program, cleaned up my disk with window's 10 utilitary and reinstalled firefox (I also tried a simple install unistall so I don't think I broke firefox by deleting files). When reinstalling firefox I tried both a 64 and a 32 bits install with current and older version none worked.

I scanned my PC for malwares, nothing found. I checked my memory as suggested in a troobleshooting page, (no problem found).

Firefox DOES WORKS in window's safe mode.

************************************ Observations I noticed via my firewall that firefox don't even send any package to the internet if I try to acess a website. Firefox does however acces 127.0.0.1 (at least it asks for permission). Firefox doesn't close if I use top right red cross, it does close if, in task bar I right click/close all windows or if I exit within the "three horizontal bar menu" I precise that my connection is ok and that MS Edge is working fine.

I repeat, Firefox works in window's safe mode.

I would really appreciate your help as I can't find any other thing to try.

After the last Firefox update (83.0) it seems Google hyjacked my browser with asking to comply with their terms. There was no change of avoiding this popup even after trying not to use the "OK with all" button. Trying to suit the compliance with my choices took a great deal of time.

With the update I lost the most used links in my browserbar and when I open a new tab the same thing occured.

What went wrong and why did Mozilla "Let it happen"

My firefox tabs has been crashing, and it has been getting far far worse. Practically none of the tab will open longer than 5 milliseconds. Other browsers works perfectly fine. I tried starting it on safe mode, no good. Tried clean reinstalling firefox, no good.

Can anyone help me why firefox is specifically crashing? About a month ago it worked perfectly fine.

Hi everyone,

I've recently migrated to a new laptop and noticed, after setting up Firefox, that Twitter embeds weren't working on some websites. After some investigation, it seems related to my Enhanced Tracking Settings.

For example, I can get the embeds to appear if I change my Enhanced Tracking Settings to Standard, or if I set them to Custom and disable either of the following:

• Tracking cookie protection
• Tracking content protection

Interestingly, leaving the Enhanced Tracking settings as Strict (or Custom equivalent), and disabling Enhanced Tracking Protection for the particular site, doesn't work ...

Is this a bug? Or have I misunderstood how this (exception) mechanism works?

Here's the page I was looking at: https://www.vice.com/en/article/4ad3qp/donald-trump-tiny-desk-electoral-college

Could someone else try experimenting with their settings and see what renders on that article?

Best regards, Ed

I have noticed that the favicons on a website are not being created when I bookmark a new site or when I use a previous bookmark, they are not updating.

They are showing as a world globe when first created.

They used to always work so I can only assume that one of the Firefox updates has stopped this working so can someone provide any information to help get this fixed?

Thanks.

Hello,

since months I have problem with automatic launch of Firefox on my computer, It's really insupportable. I'm ready to abandon firefox. I'm on windows 10 and I use Firefox 83. There is 3 different sessions on my computer and only one has the problem.... my session. Firefox launch a new windows always and regularely, when the computer start, and all the time during the use of my sessions. If i'm already on Firefox, a new windows open's.... If I close this one, few second after an other open's..... If I put this one on background, about 1 min after again an other open's. Like this always and indefinitevely. Whatever my use of the computer or the site to visit. Even when I don't use internet and use other software to work, Firefox starts up and goes in front of my software. If I let my session opened and I do nothings, after a certain time a lot of firefox windows are open. You can easily understand why I say that It's really insupportable... and this only with Firefox on my session.

My computer is protected with antivirus, and I did a full scan several time, I also tried with an other antivirus software. I used 2 softwares for detect malware... Nothing. I try to uninstall and reinstall Firefox, but the problem still the same after reinstall. I already set the "toolkit.winRegisterApplicationRestart" on "false" but firefox start alone again, again, again...

Does anyone has an idea of what is the problem and what I can do ?

Thanks.

Trying to order takeaway meal via local pub website http://www.volunteertavern.co.uk/ Click on link here takes me to website as Subject above:- https://bristolmenu.com/#/shop/volunteer-tavern/boarding This is just a blank page on Firefox, but works AOK on MS Edge and on my phone (iPhone) I found a bristolmenu cookie, deleted this & tried again - still failed. I'd prefer to keep using Firefox, but considering changing to Edge due this - any help appreciated :-) Thanks, Neil

I'm using Apple notes for every important information but this [https://photos.app.goo.gl/3Bg1rW5UtHptwrbx7] black screen is appearing on the side of the screen.

When a URL no longer exits, I get a 'redirect' and even it it does, sometimes it "steps on' the correct URL and several attempts are needed to get the correct URL to stick. The "net" gives instructions of: Step 1: Click the "Tools" menu tab in your Firefox browser and select "Options." Step 2: Select "Advanced" from the list of options at the top of the window.

But in Firefox release 83.xxx, "ADVANCED" option does not exist or I can not SEE it. Any idea on how to 'BLOCK REDIRECTS' and just get an error instead?

OR SIMPLE BLOCK URLS one just does not like without using the PARENTAL CONTROLS.

I tried three different ways, 10 times, to clear the "Cached Web Content" not matter what I do (6.0KB) remains?

Can someone please help me out here? I cleared and cleared, restarted the machine... I cannot get rid of the (6.0K)?

I'm using a 5 day old new MacBook Pro (16-inch, 2019), running MacOS Big Sur 11.0.1, using FireFox 83.0 (64-bit)

it's frustrating and I don't want anything stuck in my cache that might be tracking me, following me around.

There appears to be a bug in Firefox when I use this website, https://www.ourguide.com.au/tv_guide.php?r=melbourne&w=now

When you scroll down, the headings move right and show above the wrong information, see attached screen shots.

If you use this website on Chrome, you don't get the scroll issue so I think it is either a Firefox bug or something that needs changing in my Firefox settings.

I am running Firefox 77.0.1 (64-bit).

Any help would be appreciated, thanks.

Hi:

I installed a few days ago the latest version of Firefox on my iMac. I am noticing that when I open a new window in Firefox, a tab is opened and it shows Search Pulse. I looked it up and it appears that it is some kind of adware that is dangerous and is hard to remove. I looked up some articles and they all seem to be written by some vendor promoting a product for removal. I am very concerned asking for more problems than what I have as I am not a technical person.

Did anyone encounter this adware and if so what's a trustworthy product to remove it?

I have Norton and the free version of Malwarebytes on my computer. None of these programs caught the installation of this adware.

Any advice would be appreciated. Thanks.

Since about a week Firefox logs me out of all accounts when I close the browser. I checked the many threads here and have done everything including: Made sure it's not private browsing Made sure the history is not set to clear at exit Cookie settings are in default mode Remember history is on This problem started without me changing any settings on the browser. But I did a fresh install too, and that after clearing the Appdata too so that the install is absolutely fresh. It still continues. Facebook, Gmail, Yandex, and all other accounts are autocratically logged off which is absolutely frustrating. Can any Firefox developer please find a solution beyond "make sure the .... " etc. ?

the browser is crashing and its taking too much memory and storage even though I have minimized memory usage through about:memory>minimize memory usage but no use after few days it the logo is not displaying its displaying like in the figure attached and another thing is its taking tooo much time to open browser and also to load the page even though the net speed is good

I am getting sick of the message "A script from the extension...is running on this page" It relates to Adblock Plus which is the extension. I watch a YouTube video and then this message comes up on another YouTube tab I have open and Firefox switches to that tab and ruins my watching the video I was watching.

Is there anyway of disabling the message from ever coming up? I increased the values in dom.max_script_run_time and dom.max_script_run_time_without_important_user_input which was a possible solution I read but that does nothing.

Yahoo.com is my home page. Most times (but not always) I cannot access it unless I go into privacy and security and delete the yahoo cookies. (Just sits at new page with 3 dots moving.) I mean won't open yahoo when firefox starts, if I use the home button, or type yahoo.com in address bar. Am on Windows 10 using Firefox 83.0 64-bit. I don't want to delete all my cookies on exit, so am at a loss.

I am having trouble logging into my bank's website from Firefox. It's worked fine for several years and I have no clue what triggered it all of a sudden. Furthermore, I can log in just fine from various other browsers.

I have Google around on the issue for awhile now, and have troubleshooted several different things based on what I've Googled, such as clearing all site cookies, data, cache, etc. Also I had a pop-up blocker add-on but I removed it and that didn't do anything. Lastly, I tried completely uninstalling Firefox and re-installing it without ANY add-ons, but it still doesn't work.

Details on what happens: I go to the log in page, and I put in my user and password and click to log in, and it does nothing. It just basically refreshes the page, so the page comes back up with blank user and password fields.

Any help/ideas on the matter would be much appreciated. Thanks.
