Firefox 技術支援討論區

I am trying to sync my desktop Firefox data to my Android phone, a Samsung Galaxy S21+. In every help topic I read, it says to click the three dots on Android, go to settings and click "Sync and save data," then click "Ready to scan" and scan the QR code provided from my desktop account. The issue I am running into is that the "Sync and save data" option does not exist on my Firefox Android app. If I click on my profile on the phone, I can click "Sync" but it doesn't do anything. It does not work if I try to scan the QR code through the phone camera instead. I am at a loss for how to sync my Mozilla account on these two devices. My Firefox app is up to date. If anyone can help me I would appreciate it.

After the latest update (Monday) my Lastpass extension icon disappeared from the extension toolbar. It was still listed in the Add-ons and themes page. How do I get it visible again? I've tried to right click the Lasspass icon but "pin it" does not appear. I've deleted the extension, rebooted and reinstalled with no difference.

Hello,

I've been experiencing a great deal of crashes recently, mostly just with individual tabs, but occasionally the Firefox window itself goes down as well. I've tried reinstalling and refreshing Firefox, and I've been doing checks to see if my RAM or other hardware are faulty with no results so far.

I've mostly experienced the issue when playing videos on YouTube, but I've had crashes just casually browsing other sites as well.

Any insight would be greatly appreciated, and thank you in advance.

I have a PC that cannot access the Internet. Using a thumb drive, I was going to download Firefox then load it onto the PC. Do you think this will work and if so, how do I put Firefox on the thumb drive (be specific - step by step). Thank you

There are some pop-ups I cannot stop.

Naturally, I have clicked “stop pop-ups” in the Privacy and Security section of Firefox Settings. That has worked but not quite. I keep getting some “via l-itineraire.com”. That’s a website I used during a recent holiday in France.

So I installed Block Site.

That has an option called “Block a new host name”. I entered “l-itineraire.com.” and clicked Add. This has had no effect. The pop-ups still arrive from them.

I know there’s an option to open the website and get into the Firefox toolbar, but that’s defeated me. Yes I managed to get to click Menu, but not beyond. Anyway, that should not be necessary – after all I’ve clicked no pop-ups.

Hi, not sure the best place to ask, but it's been an ongoing issue since 2022. I kind of believe a shift in Intel has caused some of these issues, but probably not important (and I've already contacted them and did not get anywhere) at the moment.

Essentially, having Firefox running crashes the Intel UHD Graphics system, typically it is the UHD 620, but I believe I have some systems with a UHD 630. On Windows, I get a blank screen for 1.5 seconds, on macOS it crashes the entire Mac. I...I have a hard time wrapping my head around the fact I'm the only one with the issue and has occurred on multiple computers over a period of 18 months. The systems in question include the following:

Dell Optiplex 5040 MT - Fixed by putting a GTX 1650 in its 16x slot. Dell Optiplex 5060 MFF Dell Latitude 7290 Dell Latitude 7490 MSI GF63 (9th generation revision) MacBook Air 2020 w/ Intel i3 under macOS.

The thing is, with the exception of the MacBook, PCs don't report any issues apart from a "Hardware Failure" within the Reliability Monitor and the aforementioned screen shutoff. With World of Warcraft I'm able to reproduce the issue consistently under both DX11 and DX9, but Firefox not so much. I do see it occurring only on YouTube videos on the MacBook and is more common to occur on PC, but I have also had it happen on normal browsing.

I can turn off hardware acceleration and have done so, but I do wonder how much of an impact it will make on power efficiency on say, battery power. Would be something that should be fixed and I would like to put effort into getting it resolved, but I have no idea where to start. All drivers are up to date, Intel Boost is disabled (and I wonder if having it set as so causes this, though the MSI has no such BIOS setting) and it only occurs on Windows PCs with Windows 11.

Thanks for reading.

After loading the pop-up blocker extension I cannot access many links inmy email. Suggestions?

Tried uninstalling, selected to not include previous settings and reinstalled. Still having a problem.

Possible conflict with my firewall? How do I uninstall pop-up blocker?

Thank you

How do I delete all traces of FireFox. I did the "remove program" but when I reinstall it is remembering that I once had Firefox installed so that tells me it has NOT fully removed all traces of Firefox. So please tell me how to remove everything. I keep getting errors that I don't get when I use other browsers, so there is some sort of issue with Firefox so I absolutely need to remove EVERYTHING. There must be some hidden files that the uninstall program is NOT finding. I need all profiles, files, bookmarks etc GONE!!!!! so I can do a new install. PS The REFRESH did not fix my issues so please don't offer that as a potential solution.

The last Firefox update, 126.0 (64bit), that was installed 2 days ago has caused various website's commentary or forums to not be displayed. For example, Yahoo finance page, attempting to read the "community" section of a particular stock such as Walmart (WMT) nothing is displayed. This happens also on news websites that allow commentary. Google Chrome does display commentary but I don't like using Google.

This is not the first time commentary has not being displayed after an update. Happened a couple of times last year.

The desktop pc is running Windows 11, version 23H2.

Thanks, Frank

I use the Kindle Cloud Reader (https://read.amazon.com/kindle-library) to access and read ebooks in my Amazon Kindle library. Since the latest Firefox update something is preventing my ebooks from opening correctly. The ebooks open, but only a single page appears and none of the navigation controls load.

Amazon support suggested trying a different browser. I loaded the Edge browser and had no problems opening my ebooks. I prefer to use the Firefox browser so I hope you can fix this issue.

I can’t seem to open any Word files in Firefox. Doesn’t matter if it’s a new file or an old one, it just won’t open. What’s weird is that it takes me to a OneDrive page saying the file doesn’t exist or isn’t available. But when I switch to Google Chrome, everything works fine.

So yesterday I downloaded a bunch of files to mod a game. This warning appeared and since then it's been popping up every time I start the browser. I have cleared all cookies related to the relevant sites. I have removed the warning about unwanted and uncommon software. I would rather not clear all my cookies and data to resolve this, so looking for other suggestions first. I don't mind digging through files or code to make it happen.

Hey there. To get straight to the point, whenever I am watching a YouTube video on Firefox in full screen, every so often the screen goes black then slowly fades back in. I have no idea how to fix this issues and it is not my computer that is causing it (doesn't happen on other browsers, my computer was tested for a variety of problems and nothing was wrong, etc). I have also looked through Firefox Reddit help pages and the support articles on the Firefox support website but have found nothing to help. Any suggestions or help would be much appreciated! Thank you :)

This is my Mac Monterey. My Windows 10 is in Safe Mode With Networking. The last update will not download. That version is 125.0.3. What's available under Windows updates does not download either. Now I am running my antivirus on my Windows to see if it runs clean. I do not know why I cannot apply these updates.

When I click on a new tab, I get this black Google Search page, which I want to go to open my homepage. When I click on home, it does open my homepage. The image is attached. Any help on how to get rid of it would be appreciated. I do use New Tab Override, but it doesn't seem to be working.

Since Firefox update to 126.0 yesterday, any video I try to view from the Eurosport website has lost about the top third of the video. Prior to the update, I didn't have this problem with viewing the videos in Firefox, and if I access the website and videos using the MS Edge browser, the videos display correctly. See screen shots below from Firefox and Edge.

Hello,

I recently deleted pwnedpasswords.com from my cookies, as well as blocked this website; however, it keeps reappearing in my list of cookies.

I've never even visited this site (that I'm aware of), and it's a bit concerning to me.

In spite of clearing ALL my cookies (and blocking this website), it keeps appearing in my list!

Please advise :)

On my MacOS 10.15.7 system I upgraded from 125.0.2 to FF 126.0 this afternoon. When I started the new version of FF and acknowledged the "downloaded app OK" dialog all the tabs opened as expected except for WordsWithFriends (on Facebook). WWF draws the full board just fine but then throws a less than descriptive error message: "an error occurred. Please refresh." That is an infinite loop as it will return the same error no matter how many times retry is pressed. I logged out of FB and back in, just in case. No change. FB pages show fine, btw. Closed 126.0 and tried downgrading back to 125.0.2. That version with no longer load (or any of the previous four I had on hand). Consumes 100% of the CPU for about six minutes and then changes to Unresponsive in the Activity Monitor. WWF works fine in Safari and Chrome for what that is worth.
