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.

Hello!

After the latest Firefox Desktop updates (not sure which one exactly, since I didn't notice the issue immediately), I've started experiencing a problem with copy-pasting text — specifically with line break formatting on Windows 10.

Instead of copying line breaks using the Windows-style carriage return + line feed (\r\n), Firefox now copies only line feeds (\n). As a result, the text appears as a single long line when pasted into native Windows applications — which breaks the expected formatting. This behavior mainly affects:

• Text editable fields (e.g., contenteditable or textarea) in modern web applications.
• Code blocks or snippets (such as in Markdown or monospace) copied using "Copy" buttons (e.g., in ChatGPT or GitHub).

At first, I noticed this only when copying code from ChatGPT using the code-snippet copy button. But now it happens in almost all editable text areas — if I enter text with line breaks manually, and then copy it, those breaks do not appear properly in native Windows apps. For example:

• In Google Sheets, I often edit text with line breaks in a cell, but when I copy it back, it's all flattened into one line.

Right now, I have to fix this using scripts that replace \n with \r\n, but that's a very inconvenient workaround.

❗My main question is: What changed in Firefox that caused this behavior? This used to be reliable and feels like a regression. It’s a very basic feature and critically important for my daily workflow!

🔧 Follow-up questions:

1. Can this be fixed in a future Firefox update? Will it be addressed?
2. Is there a way to fix or configure this behavior right now via browser(settings, configs)?
3. Is there an extension or workaround that can restore the \r\n format without manual scripting?

Affected apps:

• ChatGPT
• Google Spreadsheets
• Trello
• ProtonMail (regular text copying)
• (more)

Thanks in advance for any clarification or suggestions!

In the last few days, after some minutes of usage, parts of Firefox become unclickable:

- I can still click on tabs to change tabs. - When hovering over the cross button to close a tab, it changes appearance as it should. Clicking the button does nothing. Ctrl+w still closes the button. - Clicking on the address bar does nothing. - Cannot click on back, forward, refresh buttons. - Cannot click on any add-ons. - Cannot click on preferences. - Can click on the button to open a new tab. There, I can enter an address. Once the page has loaded, address bar becomes unclickable again. - Bookmarks toolbar is still working as expected. - Keyboard shortcuts (ctrl+t, ctrl-w, ctrl-l) still work as expected.

I'm running ``` Mozilla Firefox 138.0 20250428130755 20250428130755 ```

on Manjaro 25.0.1 with GNOME 48

Although I have successfully logged in many times, I get an error message today: An error occurred during a connection to b2clogin.firstenergycorp.com. PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR

Hello,

I created a 1+-minute video on my YouTube channel and then posted it to my GoogleSite. But Firefox will not allow it to play because it is embedded from another site. Can you kindly help me understand how to get around this?

My goal is to create content on YT that only I can embed on my site. Yet it does not seem that there are options allowing for this. My desire is to share some wondrous FREE visual content AND to protect it by funneling it to my site.

Please know that I am not a techie as you most likely are, so your explanation is appreciated. And your assistance! Thank you. MC { yt is @ starbrightone7 } { website is wwwDOTharmoniccoherence.co ... the ABOUT page }

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?

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.

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

https://community.adobe.com/t5/acrobat-discussions/taskbar-phantom-window-when-using-multiple-monitors/td-p/14390169

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 ;-)

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!

When I startup FireFox, it takes ~15 seconds to show me an page. After loading, it works normal and loads pages within a second, until I completely close the browser, and then the first page again takes ~15 seconds. I've been having this issue for the past few months.

- I tried disabling all my addons - Launched FireFox in troubleshoot mode - Deleted everything in DataReporting\Archived folder - Cleaned out History/Cookies and site data/Temporary cached files and pages - Tried both Default and Max protection for DNS over HTTPS - FireFox is allowed in Windows Defender firewall - Tried setting 'browser.cache.disk.enable' to FALSE - Tried changing 'Enable HTTPS-Only Mode in all windows' to 'Don’t enable HTTPS-Only Mode' - Windows and FireFox are up-to-date

None of the above saw any improvement in loading time.

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

Update: Still persists in 136.0.2

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

Win11 Firefox 138.04 It appears some of the shortcuts on the Newtab page are preloading somehow.

Where are these coming from? Sidebar is off. I have all preloading off, all suggestions of every sort off, any predictive anything off.

I am not experiencing this on my win10 machine.

How do I stop this?

I am wondering is this an issue between Firefox and YouTube as I have three other browsers on my computer and YouTube works fine on them. I prefer the picture in picture option on Firefox. There was a browser update like 6 months ago and after that Youtube doesn't work properly. It loads the page itself but not the video and in the rare moment that the video loads it is at the lowest possible resolution and will play for only around 10 seconds before buffering again.

please forgive me for asking again, but I REALLY need my addons to work. Firefox disabled my addons, forcing me to upgrade to a version of firefox that I don't need, since the old one was working just fine. The new version does not seem to appear to have downloaded properly, and neither version is allowing my addons to work or be re-installed. Please explain it to me like I am 5 years old, and help me to get this fixed without losing any of my info that might be stored in the addons.

 Thank you.

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.

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.
