Firefox 技術支援討論區

Your instructions under "help" say to click on "Firefox" and click on "preferences". When I click on Firefox the menu does NOT have "Preferences" in it. What's up with that?? And how do I clear the cache and cookies?

On a couple of websites, but in particular Rogers.com, the captcha just never ends. It asks to click on all the bicycles, I click on them one at a time until no more appear, hit verify, it brings up something else. It will do this dozens of times and just never ever end.

Switch over to Edge, does the same. Switched to chrome and it works fine. Has google done something to captcha to deny it working on other browsers?

I have checked to see firefox is up to date and it is. I have disabled all extensions/addons. I have run malware/virus scans. On the Rogers community forums there are all kinds of people having problems but there are no solutions on how to fix. Oddly (or not) the problems are similar...captcha won't work on Edge, Firefox but will work on Chrome.

I have a Lenovo ThinkPad X1 Yoga Gen 6 (20XY005MGE) with Win11 Pro.

All of a sudden, Firefox does not play any sound. I notice that it does not show up in the volume mixer. I tried:

• this solution: https://support.mozilla.org/de/questions/1278299
• Reboot the PC
• Uninstall and reinstall Firefox
• Deactivate all Extensions
• I worked my way through the manual pages (none of which mentions Firefox missing in the volume mixer)

Youtube does not play sounds, the Spotify page notices that it cannot play sound (the spotify App for Windows works fine, though). News sites (tagesschau.de / video, deutschlandfunk.de / audio) play the video, but no sound.

I had the problem a few months ago already but I cannot recall the solution :(

Thanks for helpful hints!

After updating to version 121, the cursor theme, while having it on the window, changes from the default one (Breeze) to Adwaita while also getting like 2x bigger. How do I change it back to default theme and size?

One of the websites I use now gives me the following error: Please unblock challenges.cloudflare.com to proceed Microsoft edge does not have this problem, but I don't like using edge. I used my search and found many causes. I did the following: Went to my firefox settings and cleared cookies and history I ran two security programs, bitdefender and maleware bytes I still have the problem.

Firefox use 100% of my cpu and drops frames when playing 8k video (gpu acceleration setting is turned on). Chrome instead have no frame drops and does not use 100% of the cpu.

I tried to google it and use some solution, but no effect in my case.

PS: 1st picture firefox, 2nd chrome.

I am trying to block myself from checking on my old employer's website, and I need to block myself from being able to go to their web page. How do I block a specific website? I do not want to access this site, and I find myself checking the site. I sound nuts, I know. But this is for my own good.

With 'Back up your Firefox data' it says it saves all open tabs.

What is meant by 'open' tabs? Is it tabs that I have clicked on during my session?

I have just over 300 tabs, will Firefox save all of those tabs in the cloud or only the tabs I clicked on during a session?

Firefox displays text on the .xml page as html code instead of rendering is as normal text. The layout and images on the page look as they should.

There is nothing wrong with the page, as it is rendered perfectly in Chrome.

In addition, this page doesn't display at all on the phone. When I click on the link it asks me to download it and then asks me which app I want to open it with - instead of simply rendering the page.

I have seen some old threads on this topic, it looks like this issue haven't been resolved for few years.

My question is not just about fixing it in my browser but at the root cause. This page is the RSS feed of my podcast which many people want to access and many use Firefox as their browser. Unless I tell everyone to use Chrome instead.

Can someone help? thanks.

When selecting "Open in Firefox" in the "What do you want to do with this file?" box or on about:preferences and then opening a PDF file on the web, instead of downloading the file to RAM and opening it with its online address, Firefox downloads the PDF to /tmp/mozilla_${USER}0 and opens it from there. This also adds it to the download history. I have set the about:config flag browser.download.start_downloads_in_tmp_dir to true so the files I just open and don't want to permanently download don't clutter my $HOME/Hämtningar (downloads) folder. I tried to first prevent that by selecting the default action to do when tasked to open a PDF, but that didn't fix it, so I set the about:config flag. Unfortunately, setting the default action stopped Firefox from opening a PDF inline without downloading it and I cannot find any option along the lines of "Preview in Firefox" (as described in this support article ).

Hello,

James here. I CAN NOT find the Firefox application file location. There is no option to show file path upon right click of the desktop icon and I can not locate it in File Explorer. I have done an entire (C:) drive search and turned up nothing. C:\Users\(username)\AppData\Local\Mozilla Firefox does not exist in my file system. I am at a loss here and it's driving me bonkers!

I see where other people have posed this question but the procedure offered is not available to me.

I am using Firefox (Flatpak) version 121.0 on an Ubuntu 22.04 laptop.

On installing a new extension I should either see the extension's icon on my toolbar or else have a clear means of adding it. I have neither.

Clicking on the jigsaw icon in the toolbar, I get migrated to the about:addons page. On clicking the Extensions tab, I get the screen listing all installed extensions. Each extension has a ... icon beside it. But when I click on this, there is no "Pin To Toolbar" option.

What is wrong here ?

Hi all,

I feel like this is a problem that must have been experienced and solved a thousand times... however I've tried all the suggested fixes I can find and the problem still persists.

When I load Firefox the pages take ages to load. It doesn't matter what the page is, it takes ages, except that about: pages load fine, no problem. When I say pages take ages to load, I mean that everything about the page takes ages, not only the next, not on the images and other content etc, everything. This only started happening today and I only created a new profile a month or so ago. I don't have many tabs open (maybe 20) of which 9 are pinned. I do have lots of extensions installed.

I've tried troubleshooting/safe mode, that makes no difference.

Private browsing and loading another profile are fine, they don't have this problem.

I've cleared all cache and data, cookies, etc, including startup cache.

I've deleted the content-prefs file, and removed places files.

I've tried disabling and enabling hardware acceleration.

I've tried disabling TRR.

Probably some other things too, but so far nothing has worked.

Suggestions please! :)

Hello

I got a new Asus Vivobook Core i9 16G Ram I did the basic Windows 11 installation for the Laptop and installed TotalAV.

After all Windows 11 updates passed, I wanted to install FireFox anf got this issue: Firefox cannot start correctly (0xc0000022) after version ..

I tried several time to close all Firefox task, uninstall, remove all files from existing profiles (local, roaming, etc...) so as all files under "Programs"". I made sure to get the latest code, but I always get back to this issue.

While opening FireFox, I immediatly get a Crashed Tab reported. Even the Settings are not opening in a Tab.

I even tried to use a older version. Same issue... Never the less I can Update the older version in "About FireFox".

After update I see 122 installed

I used FireFox for many years, and wanted to continue.. In the meantime I installed Opera

Any help is appreciated. Thank you in advance Laurent

No longer able to copy or paste text on Firefox with Windows 10. Copy and Paste are greyed out in the right click menu after selecting text. Using CTRL-C, V or P does nothing at all. Still works fine in other browsers. What has Firefox broken again this time?
