Firefox Community Forum

Hi. According to my observations, only Mozilla Firefox and Adobe Reader have this problem so far.

Windows 11 + Multi-Monitoring Windows 10 have this Bug not !

Open Firefox, drag the window to the second or third monitor, and suddenly there is another hidden Firefox window on the taskbar of that display. If you move Firefox back to the main monitor, it disappears again. Or you can close Firefox and restart it on the desired monitor.

This is an annoying little bug, and I don't understand why Microsoft or Mozilla haven't fixed it yet. It's easy to reproduce and has obviously been around for a while. Since it only affects the two programs mentioned above so far, an MS update will probably not fix it; instead, the developers at Mozilla and Adobe need to address it.

Here the Same Topic in Adobe Forum. No bug fix to date

I hope you release a bug fix soon... but since that hasn't happened yet, I'm afraid it will take a while... I'm surprised, because I'm sure many people are experiencing this annoying problem, and in my opinion it's not a big challenge for your developers.

@Mozilla Please Fix this Bug. I know Windows 11 is not better than Windows 10 but Supports End and many Users and Customers used in Future this OS and if you don't want to lose any more market share, it's important to fix this minor bug for ordinary users too. Thanks ;-)

Several sites I use regularly (for instance, The Guardian) use recaptcha as part of the login process. It fails on Firefox, though I can log in on Chrome. I dislike Chrome, and prefer Firefox for several reasons, including that it is easier on my eyes. I note that there are many complaints describing the same thing that I experience: recaptcha fails to load, or there is simply a blue circle turning in perpetuity with nothing happening. I have removed recent cookies etc, but no change.

There are some sites that use recapcha that I can sign in on using Firefox with no problem. I am wondering if there are different versions of captcha? This started the same week both Microsoft and Firefox updated. Firefox has updated several times since then, but recaptcha is still nonfunctional: FF is not loading it, at least on some critical sites (perhaps the ones that use the most recent recaptcha?

I have reported this frequently for last several months. I notice that this is a continuing problem for many people. Why is it not fixed?

I just installed Mozilla VPN but when it's active my internet connection stops working. Pretty sure whatever protocol it's using is the problem with the WIFI signal, but I can't find how to change the protocol like every other VPN service allows. How do I change the VPN protocol? There is strangely no article already on this site for this common problem.

Firefox on MacOS in full screen mode makes the black offset between the screen edge and the Firefox window after logging in after MacOS is locked. It fixes itself when you exit the full screen and enter it again.

How to reproduce?

• Open Firefox and enter the full screen mode
• Close your MacBook and wait until it prompts you for your password or touch id
• The Firefox window has black offset between screen edge and the Firefox window, that was not present before
• Exit the full screen and get into it again, and the offset is gone

I have a 2023 MacBook Pro and a Synology NAS. Fairly recently, when I have tried to access the web site for the NAS using Firefox, I have received the following error message: "Unable to connect. An error occurred during a connection to [the IP address].” I am able to access the web site using the Safari and Bing browsers, and I also am able to access the web site using Firefox on an iPad. I already have contacted Apple and Synology support personnel, and have been that the issue is not with either Apple or Synology products. Please let me of any potential solutions to this problem that Mozilla may have.

REPEATING IMAGES involving . Macbook Air M4 Tahoe 26.2

When sliding from the primary Mac screen to another on the same computer the Firefox image (and ONLY that image) is duplicated on each additional screen image loaded making the use of multiple screens virtually useless.

When open Google Drive using Firefox, I cannot click on any documents. I can open folders but the documents in these folders I cannot open. I can open Google Docs and then access documents but all documents through Google Drive including in the Shared Folder are greyed out and when I click on any of these I get the pop up "This file cannot be opened because you're offline." I can access Google Drive and its documents using Chrome. I would prefer to use Firefox.

I have updated Firefox, cleared the history, and emptied cache and cookies. I also logged out of and then back into my gmail account.

The image shows what the drive looks like when opened in Firefox.

Hello, I have 3 PCs. One is Windows 10, Firefox 131.0.3 One is Windows 10 firefox 131.0 One is windows 11 firefox 131.0.3

All 3 PCs are running BOINC, using the remaining CPU power up to 100%

On PC W10 + FF 131.0 and PC W11 + FF131.0.3 BOINC and FF share the processor time up to 100% On the PC W10 + FF 131.0.3 when FF is dispatched, no processor time is assigned to BOINC and CPU busy is no more 100%. This situation occurs frequently and can last several minutes.

When File Explorer of Windows 11 25H2 tries to access and open an icon-file in the FF (144-64bit) profile's 'shortcutcache' folder, explorer gets Access Denied. The account running Firefox has admin rights.

Looking to the ACL of the profile folder containing the folder 'shortcutcache' show no reason for the blocking. Trying this with a new profile did not help.

Hello,

I checked the troubleshoot and gave all the necesarry permissions on my Mac for Google Meet to use my screen (allowed audio, video and screen recording). Nevertheless, I cannot manage to share my screen on Google Meet. As shown in the screenshot, it offers the option to share my whole screen (I cannot select a window or a tab...) but for my audience neither this is working.

Could you please help me fix this?

Many thanks in advance!

Hello,

WSJ.com is unusable on this browser. I've cleared cookies/site data, as well as disabled adblocker. Every other website works fine. Every other browser loads WSJ.com with no problem. But on Firefox with WSJ, the website loads very slowly, only ever partially, and sometimes not at all. This has been a perennial issue. Thank you.

Cannot Log on to Costco.com site after update to Firefox 133.0 in Win 10 pro on 2 computers. Both are up-to-date with latest software.

Entering valid account and password cause the Costco logon page to freeze for a minute then returns to log on screen with no messages about failure

Same behavior on two computers. Log on to Costco via Microsoft Edge works perfectly (on 2 computers before any trouble shooting ). Logon with Firefox 133.0 works with every other site that I regularly use - Samsclub, Amazon, Yahoo mail, my own mail servers, NYtimes, WashingtonPost, Google, Walmart, and others

Trouble Shooting Steps taken with no change in the problem logon to Costco + Cleaned cache / cookies + Disabled virus protections + Disabled firewall + Stopped all security services + Rebooted + In settings | Privacy & Security: Added Costco.com as Exception for Enhanced Tracking protection + In settings | Privacy & Security: Added Costco.com as Exception - Cookies and Site Date

I watch Rakuten Viki, and suddenly a recapcha box is popping up on the bottom right, blocking the full screen button.... so annoying,,,, how can i get rid of it/ THANKS

Popup GUI elements if pulled up twice in quick succession spike my CPU usage and crash the program

some examples: -menu bar menus -the menu button -context menus (websites with their own context menus do not do this) -preview tooltips

I've tried disabling extensions, turning hardware acceleration off and on and disabling AI to no avail. Disabling the preview tooltips 'worked' but I'd prefer not to disable everything here. Are there any other settings that might help?

Hiya.

So if I download an attached file on gmail using Firefox... it crashes. If I open up a new tab on Firefox... it crashes. It only started this week.

I'm using 12.7.6 and I really don't want to go back to Chrome, so I hope you can help.

The macbook completely freezes apart from the mouse pointer which moves, but cannot open a thing. Every time I have to turn the macbook off to restart it.

I tried uninstalling and reinstalling the latest version.

Best, Mike
