Firefox Community Forum

I've had increasing issues with Firefox performance over the past month or so. I kept hoping an update might fix things but it's getting to the point I need to use Chrome much of the time now. I read the help article for websites not opening with Firefox but opening with another browser and had already done most of the things: clearing data and cache. I don't know what proxy is but I looked at my Chrome settings and changed Firefox to match (automatically detect settings). Nothing has helped. Sometimes a site won't open and sometimes I get into a website and then a random page within the website won't open. I have only a few pages open at a time. It might have started at some point after adding Facebook container to the extensions. Other extensions are: Duck Duck Go, Malwarebytes, Google Analytics opt-out, Read Aloud and U-Block Origin. Any help appreciated. LC

I have an account with Songsterr. It's a music tabs site.

I moved over to Firefox as my primary browser relatively recently & I've noticed that the captions in Songsterr are all messed up. I've been on to Songsterr about it & they cannot solve it but, on a whim, I checked Songsterr in Safari & everything appears normal so I'm going to assume for the moment that this is a firefox related issue.

I've added 4 screenshots. The first two are from Safari & show how the captions should appear. The second two are from Firefox & you can see that it's all messed up.

I found an article on Reddit that may be related but I wanted to check here first & see if any of you could shed any light.

Hi, I have been using Firefox for quite sometimes now, and I've always had problems loading any kind of maps on any website. I frequently need to modify or create GPX files, and I usually do it on my phone because the map never fully loads : by that I mean there is a massive grey square in the middle and the map only loads on the side, like I can see names, routes, etc but not in the middle.

Even if I zoom in or zoom out it's only the middle which is grey. If i move to the side, the previously centered area will be displayed on the side of the map. And it only does that on Firefox, not on Edge or Chrome or Safari etc.

I've tried uninstalling and reinstalling Firefox and deactivating all addons but nothing works. If you have some ideas on how to solve this problem id gladly try them out (sorry for the crappy english)

Latest version of Firefox browser (142.1) recently installed on my laptop and desktop both running Windows 10. The former continues to support Flightradar 24. The latter no longer does. Message reads 'Unfortunately, your current browser does not support WebGL2 . . . most major browsers (including Firefox) do'! Is there a reason for this anomaly, please? Plus a solution?

Using an Android tablet (OnePlus tab 3) I can use the pen to write in the address bar but I cannot use a pen to write in any text fields on websites while browsing in Firefox (on google.com for example, or writing this), which works on other browsers like Chrome or duckduckgo browser. The touch input of the pen is recognized to scroll zoom or select text, but not to write. Is this feature not supported on Firefox or am I missing something

Thanks

I'm on MacOS 15.6, and FFox 142. My company recently rolled out "PSSO" for Mac users, and it works pretty well on non-Microsoft sites. However, when accessing resources behind MS Azure/Entra, such as outlook.com, sharepoint, even github, we get the following error from "login.microsoftonliine.com":

You can't get there from here Your sign-in was successful, but you can't open this resource from this web browser. You might be able to access it from the Safari browser (ask your IT department for a list of approved mobile and desktop applications).

All of these worked fine before PSSO while using Yubikeys (in fact I plan to revert to Yubikey next week).

The IT department says that Mozilla needs to implement this, referencing the "only applies on Windows" statement shown on https://support.mozilla.org/en-US/kb/windows-sso . They (and I) have demonstrated that it also works just as intended on Chrome and Edge browsers.

And yet, we see that "Microsoft SSO" was added in FFox 132: https://bugzilla.mozilla.org/show_bug.cgi?id=1768724

Who needs to do what to make this work on Microsoft web-apps?

Hello again. Re my very recent post about a game on facebook functioning very slowly after the latest update, I now discover a worse problem with a word-game on a different site that I have also played for years on Firefox. Basically, after the new update, I find that I am no longer allowed to complete a move. Given the now 2 problematic situations I have, do I now with great reluctance have to abandon Firefox?

Up until recently Bing Maps in the UK has the option to display Ordnance Suvey Maps and the function to measure distance.

Now, using Firefox, Bing Maps display a Beta version with very limited functionality. Using Microsoft Edge, Bing Maps have all the functionality that I expect.

Has something changed within Firefox that has caused this problem? Is there something that can be done to allow Bing Maps to work correctly from within Firefox?

Hi - After the latest Firefox update on my laptop around 2 days ago, I am now unable to play a game on facebook that i've been playing with no probs on Firefox for years. After this update, this game of all things (nothing else is) is slowing Firefox down. Now the page fully loads very slowly - as do the moves I try to make. Am I correct in thinking that there is basically no option to safely return to the previous version? If so, why at the very least was I not given the option not to update, while acknowledging I may be at greater risk if making such a choice. Looking forward to some help please! Thank you Steve

Running an old Mac mini and Catalina. Firefox 128.14.0esr (64-bit)

As of today I can't log in to PayPal from my desktop using Firefox as my browser, it says I am "blocked" I spoke to Paypal and the account is fine. From the same machine and the same internet connection, I can log in with Safari and do not get the Blocked message. I can log in via Safari and my iPad. I can log in with ethernet or WiFi (different ISPs, one BT, one Spitfire) as long as it isn't Firefox.

All signs point to the old browser. Can/will this be fixed? Cheers,

I cannot get certain videos to play on Firefox. YouTube, Instagram, Tumblr all can play videos. Pretty much everything else doesn't work. Patreon, I get a black screen. On Twitch, I can only see the 'not currently streaming' screen, even if they're currently live, and VODs don't work. My computer specs are below. Operating system is Windows 10, I use Windows Defender for anti-virus. Everything works completely fine in other browsers. Here's everything I've tried to fix this:

• Updating Firefox
• Updating my computer
• Running in Incognito
• Running in troubleshooting mode
• Allowing autoplay
• Disabling hardware acceleration
• Disabling addons
• Clearing cache and data
• Enabling/disabling DRM content
• Installing Windows Media Pack

My specs: Processor Intel(R) Core(TM) i7-10700F CPU @ 2.90GHz 2.90 GHz Installed RAM 32.0 GB (31.8 GB usable) Storage 932 GB HDD TOSHIBA DT01ACA100, 477 GB SSD Micron 2300 NVMe 512GB Graphics Card NVIDIA GeForce RTX 3060 Ti (8 GB) Device ID C6C4BD2F-BD36-40B6-A917-13896770194D Product ID 00325-82058-09721-AAOEM System Type 64-bit operating system, x64-based processor

This has been going on for over a year now. I've gone through all of the above troubleshooting steps multiple times. The only progress I've made is getting YouTube from nonfunctional to working again.

Yesterday (8/19/2025) I updated to Firefox v. 142 from v. 141.0.3. The Firefox update was the last thing I did prior to shutting down my computer. Today, when I booted up with version 142.0 many of my bookmarked websites don't work. I am using a iMac Retina 5k, 27-inch, late 2015 desktop computer using macOS Monterey v. 12.7.6

I called Apple tech department & explained my problem (see above). He had me delete the cookies for Firefox to see if that would correct the problems. It did NOT resolve the problems. He had me switch to Safari browser to see if I could the access the websites with which I was unable to access. I was able to do so. He stated that the problem was with Firefox and that he could NOT help me any further.

I have NOT used Safari for a decade or more and am NOT familiar with it because I found Firefox to be much better and easier to use. Until yesterday, I had NO problems. Now I am desperate to be able to continue to use Firefox but can't access important sites that had been available until the 142 upgrade. HELP, PLEASE

As the title suggest - I am unable to access LI at all.

It's not a profile issue because it loads fine on Edge. It's not an extension issue because it causes the same problems in troubleshooting mode, and it does get me to at least the login page on a private window.

Please help. I'm not sure how to resolve this. It's blocking a lot of my work.

Thanks in advance!

Hello Forum,

I am unable to see the microphone/record audio button in Google chat in Firefox. This problem is NOT existing in Chrome/Edge/Safari.

Firefox version: 128.13.0esr (64-bit) OS: MacOS Tahoe 26 Beta 7

Please see the screenshot

I have downloaded and installed the latest update for Firefox. v142.0 64 bit. It is not playing well with Facebook on my Windows 10 pro 64 bit machine. Slow or no response to mouse clicks. I have closed Firefox and reloaded after a reboot. No problem when using a different browser. I have not discovered issues with the several other platforms I visit.

Hi everyone.

A few websites for the past month don't work for me on Firefox (WIn10), but work on Firefox Focus (iOS), Edge (Win10), Safari (iOS), etc.

I think maybe it's a configuration issue or a corrupted file or something. I don't have strict tracking protection on, and tried the troubleshooting mode. Or are some sites blocking Firefox Desktop in particular?

I also tried using a VPN to make sure it isn't geo-blocking. Example: https://wikidiff.com/assorted/assortment

Attached screenshot. Many thanks.

I have had this problem for many years now. When I complete a customer journey on some sites, usually with a payment involved, the final submit button doesn't work at all, and I have to redo the transaction on Chrome.

This happened yesterday on Ryanair's site and, by the time I gave up and redid the journey on Chrome, certain prices went up. So, now I'm losing money :-(

Firefox has been my default browser for a decade or more, despite my husband's teasing me about this issue, but I might have to give up and make the switch to Chrome or Edge. Please help!

Please note that Firefox clears my cookies every time I close my browser.

Thanks!
