Firefox 技術支援討論區

I have searched the "Knowledge Base" to no avail--no solutions, just others with the same problem. Every day a handful of fresh Trouble Reports pop up on my desktop, even though Firefox is not even running (as verified through the Windows Task Manager). It got so bad, I uninstalled/reinstalled and the problem persists. Otherwise, the browser works fine. My expertise lies outside trying to decipher arcane strings of data buried deep in the bowels of my computer, and frankly I should not have to start hiking up a steep learning curve just to get this to stop. I should add, I have been a fiercely loyal Firefox user since its inception.

I'm not super happy about sharing internal data with the rest of the universe, but have done so anyway in hopes we can get the madness to stop!

Hi, I just replaced my SSD (Samsung 960EVO m.2 250Gb) for a larger/faster SSD (Samsung 980 m.2 1Tb) . I'm on Windows 10 and have 32Mb Ram. Firefox is now very slow on some websites (not all).

This example is typical and has occured on multiple sites. To test and compare, I copied the URL, created a new tab in Firefox, then Paste and Go. I timed this 3 times and each time was 30 seconds. I Pasted the same into Chrome and Edge and each time it was instant. https://savingschampion.co.uk/best-buys/personal/easy-access-accounts

On my previous SSD, there was never an issue of any lag on any site.

BBC.co.uk/news is fine, as are several other sites. Does anyone have any idea what's happening? This is making Firefox unworkable for me, so unless I can fix the issue, I will have to move permanently to Chrome or Edge. That would be a shame after many years with Firefox.

Thank you in advance.

I asked a question to add details after an answer but when I have an error when I click to the "Post a Reply" button.

52.9.0esr is claimed to be the last version for XP. Unfortunately it is not quite true. It is for XP SP2 ONLY. Trying to install on SP3 ends with the message that SP2 is required. IMO the installer is simply too strict on demanding exact version of SP ! https://www.mozilla.org/en-US/firefox/52.9.0/system-requirements/

I went through the list of versions (thanks Mozilla that they all are still available!) and found that the last version I can install is... version... 12.0b6. https://www.mozilla.org/en-US/firefox/12.0/system-requirements/

And indeed I installed 12.0b6 successfully but I would like to install 52.9.

Good morning, Recently I discovered there are two maps called "Andere bladwijzers" in my Firefox browser. I deleted a submap in the second map and noticed this submap had also disappeared in the first map. Is there something I must do or can I leave these two large maps as it is? Thanking you in advance for your reply. With kind regards, Ed Schijf, the Netherlands

I wanted to use sync to transfer my tabs from my previous MacBook to my new MacBook. I reset the previous MacBook and now when I login to the new one, sync does not show any of my previous tabs.

I expect the back button to return to the previous page visited, but too often the button either doesn't respond at all or a right click is required to view the page history. Is there something I need to do get the original function of the back button that I thought was universal in most browsers?

Title. Whenever I open Firefox, the window will appear shortly after, but it will take around a minute for websites to load. This applies to both tabs from older sessions and opening new tabs. It doesn't matter whether I've just booted up, or if I've been running for half an hour. I've tried disabling all extensions, but that hasn't fixed anything. I am running Linux Mint 21.1 Cinnamon on my Gaming Laptop. Specs shouldn't be an issue. ANY HELP WOULD BE MUCH APPRECIATED!

I have run Firefox for years on up to 4 PCs at once, everything has always synced and screens all look the same. Recently one laptop lost the addon extension icons in the Firefox toolbar. They remain on all other installations. I have tried uninstalling Firefox and installing an earlier build, and also the latest Beta build with no luck. All extensions show as installed and activated. I have copied the Profile from another laptop. I have of course done a reset. Any other suggestions?

I have my setting to ask me what to do with files, pdf , whether open or download i have it all set to ask it asks , it opens them in firefox but still downloads them to my computer. i don't want them to download , i'm never sure if they are safe how i stop stop auto download This has only been in the last few updates this began

Hello,

we use firefox in our company and the requirement appeared to turn on the security setting "Delete cookies and sitedata when closing Firefox" due to our security guidelines.

I´ve already checked the "Enterprise Policy Generator" Plugin, but there is no such option. Is there a possibilty to check this option and block it for the user by the about:config page?

Thanks in advance, J.Stempel

In reference to my previous post ( https://support.mozilla.org/en-US/questions/1382198?page=1 ) I have noticed that the "jumping while scrolling" in the Facebook News feed has returned after a couple of months of proper behavior. Ver. 108.0.2 It's not as bad as it was but it seems to be getting worse.

Is the circus back in town?

Am I going to have to move back to Chrome again ?? >:-(

As of today (worked yesterday and previously), I cant access Youtube using Firefox with my ProtonVPN on. Chrome+ProtonVPN=yes Firefox+ProtonVPN=no Firefox withoutVPN=yes Can I fix this in Firefox settings or ProtonVPN settings. I have contacted both.

For the past week Firefox has been opening Youtube in dark when for the last decade I've been using light. Every time I change to light it works for that tab, if I open a new tab and load Youtube it opens in dark appearance. When I change to light and then click my avatar in the top right of Youtube it's still states I'm in dark when it's in light.

Why doesn't the light appearance stay? I've cleared cookies and that doesn't seem to work. It's also specific to Firefox, this doesn't happen in Microsoft Edge.

Alright first of all I already tried all the tipps about Proxy and basically anything network related. It also happened out of nowhere since I was using my computer the night before but when I tried opening Firefox the next day it wouldnt load any site, crashed if I tried too much or got really weird and even if it did load after a long time of trial and error it only lasted for a bit and didnt load fully either. I'm on version 108.0.2 as of the last time checking. Everything else seems to be updated as well especially since other browsers work perfectly fine. I also cant really click on much since as I said if I try too much it crashes or doesnt work as intended. I'll provide some pictures which might help the cash report just in case.

I'd also rather not try reinstalling everything since I have a lot of rather important tabs open and I dont wanna risk losing any of them since im not sure how well the Firefox sync. works in this case.

I've recently switched back to Firefox from Edge and have run into a frustrating issue.

When I try to print documents from Firefox, the "Color Mode" in the print settings is grayed out so I can't select B&W.

This same problem exists both on my MacOS laptop + my Windows 11 desktop. Additionally, they are connected to different printers on different networks. It also occurs whether I'm trying to print a PDF or anything else in Firefox.

Based on this, it appears Firefox is the culprit here.

Any ideas on how to fix this?

Firefox Version: 108.0

I pressed some button that is on the left side of the keyboard, I didn't see what it was, and after that my url bar for some reason has a space that leaves the text on the right after that
