Diễn đàn hỗ trợ Firefox

All, most recently I'm having problems with uploading files from my PC to respective internet platforms. It started with file uploads to ChatGPT, whatever I tried, the upload stalled and ultimately failed. Second platform was Vimeo, same problem, file upload stalled and finally failed. Such problems do not occur when using Chrome as browser, or when using Firefox via my Android. Never had such problems before. Firefox runs on latest version 142.0.1, cache is empty and all cookies deleted. System details: Desktop PC, Win 10 Pro, Vers. 22H2, all updates included. Have the same problems on a different Desktop PC. Very much appreciate you feedback and ultimately solution of the problem.

Kind regards, Hanns-Georg Büschelberger

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.

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 using Firefox Developer Edition 143.0b5 (64-bit), running on macOS Big Sur (11.7.10). My bookmarks for Facebook, Instagram, and Threads won't load on the first click. Most of the time I am presented with a blank white page. Sometimes I might get part of the page to show. I have to click on the bookmark a second time and then the page loads completely. This behavior doesn't happen with any other bookmarks I have.

Anyone know why this is happening?

I've just updated my Linux Mint to 22.1 and Firefox to 142 on two computers. Both show the same behaviour. On websites of the Stackexchage family (Stackoverflow, Superuser, Crossvalidated, Academia...) the comment function seems to not work anymore. I am not offered a button to comment, and clicking buttons to see more comments that are already there don't show the comments but rather send me to the top of the page. I can still answer. The problem seems to be with Firefox 142 as it worked well before the update, and it still works well with Firefox 142 on Mac and other browsers on Linux.

This looks like a minor bug, not sure whether it is specific to Stackexchange or other websites are affected, too. Is there any help? If not, where can I file a bug report?

Hello and thank you for the help,

I have tried applying for any college on CCCapply's home page (https://home.cccapply.org/en/) and once I input the college and click it or click enter, I either get stuck at a white page or CCCapply has an error page saying I am using a proxy.

I have tested this on macOS Sequoia, Windows 11, Linux Mint, all on the newest updated Firefox. I also tried this on mobile Android and had the same issue.

I have tried on Campus networks, home networks, and cellular networks, all the same issue. Chrome, Edge, and Opera all work perfectly fine.

After trying normally, I have deleted all browser data/cache, turned off Enhanced Tracking Protection and every security setting I could find in the settings and still run into the same issue.

Thank you for the help, Connor

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!

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

Hello, For some time now, links in Gmail e-mails are not working properly on Firefox (MacOS). If I click on the same link on the e-mail within the Mail app of MacOS, or using Gmail in Safari, it works fine. Even in the Mail app case, the links open in Firefox, so the problem is in Gmail within Firefox. I've had problems with links in e-mails coming from Amazon (I bought an e-gift card who's link did not work) and also in e-mails from Clarivate (Web of Science Alerts, links to the e-mailed records, image attached). Any suggestion on how to fix this problem? Thanks in advance.

Siriusxm won't display fully on my Firefox, the selection buttons don't show. It works fine on Chrome - Sirius says it's about Firefox. file:///C:/Users/Owner/Downloads/Screenshot%202025-08-27%20at%2013-38-08%20SiriusXM%20Streaming%20Music%20Sports%20News%20Podcasts%20&%20Talk.png

I don't understand! I'm able to order merchandise on other websites, including Mary Kay's. Why is this any different? They are May Kay business cards for my Mary Kay business! (I'm also 93 and not very savvy about this.) Please help. Ellie

Hello,

I am facing an "Aw, Snap!" error when I visit this website: [https://littlegames.io/|https://littlegames.io/] in Firefox. However, the same website works fine in Chrome. Other websites also open normally in Firefox without any issues.

Can someone please help me fix this problem?

Thanks.

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.

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
