Firefox Support Forum

I noticed during a firmware download with the file extension .DAT that Firefox removed the extension. The file was not recognizable during an attempted firmware upgrade afterward. This is a new issue occurring sometime in the past several months, since last firmware update. Firefox preferences are set to download .DAT files. No other settings are listed for that file extension. I verified the issue points toward Firefox by checking the download with another web browser which completed the download with the extension.

I used the same account with two computers. I always keep my account in sync. Actually, they do not. My previous notebook has a series of bookmarks, but the bookmarks in the latter one is exactly different. It seems like two accounts, but I log in with the same account. Miracly, when I log the same account with my phone, the bookmarks in my phone is sync with my previous notebook I don't know how to solve it and appreciate your answer.

我有两台笔记本，登录同一个账户时是不同步的。两个笔记本的书签页完全各顾各，但我登录的是一个账户且一直保持着同步。当我用手机登录同一个账户的时候，手机会有第一个笔记本同步；第二个笔记本就好像完全是新的账户。 我不知道怎么解决这个问题，希望专业的你的回复。

Recently got a new computer with Windows 11, and now whenever I try to play a Youtube video or videos on other sites, Firefox as a whole slows down. There is a delay when starting the video, and at times Firefox stops responding if I try to switch to another tab when this is happening. (Not always, but sometimes).

The delay can be anywhere from 5 to 45 seconds or so, and repeats whenever I pause and unpause a video, or even rewind slightly. This doesn't seem to be buffering, and videos seem to work just fine on Edge. Any idea what could be causing this issue?

Thanks to Robert for a quick reply. The problem is that when using FIREFOX, images that are on my website do not appear. However, when using Chrome or any of the others (including my phone), they do appear.

I also think that Firefox is preventing some of the links I receive from connecting.

In short, I am not very happy with Firefox!

Firefox will not allow me to log into Nest home page with google account. When google account is selected at login it will loop back to select which account to log into with. Never had this issue with previous versions of Firefox Have used the open/option to determine that the issue continues to exist. Version 102 Mac laptop

Cannot open PDF from MS365/Sharepoint site. Error message: "ERROR: URL provided is expired or invalid. Please reinitiate the workflow..." Checked:

1. 1 Other file types open/download correctly.
2. 2 Other browsers open PDFs correctly.

The issue seems restricted to Firefox and PDFs.

My banking website works fine except for 2 tabs which eventually comes back with page not found due to a technical problem. I think started happening with the last update to Firefox. I have no problems using MS Edge. I have contact my Bank's help line and only suggested clearing data cache and cookies, but it made no difference.

unable to use on Firefox: Bank of America, CapOne Visa, CostcoTravel.com, for starters...which setting is preventing this? So I have to use Chrome; pls save me from that. On CostcoTravel.com, the circle just spins...for hours--just trying to sign in, even with Enhanced OFF.

I believe the latest Firefox update has a glitch which prevents me from downloading audiobooks through the library's Overdrive app. After failing several times and talking to a very patient librarian, I finally used a different browser and was successful.

I just bought a new laptop and am trying to sync my firefox account. Whenever I try to sign in from the new computer I keep getting an incorrect password message despite using the correct password. What am I suppose to do here? I don't want to lose all my saved info and everything else.

Hallo,

I have: Firefox 102.0 (dark mode)

OS: - Win10, 64-bit (20H2 up to date)

addons: - Adblock Plus - uBlock Origing - Concent Blocker - Video DownloadHelper

In the last days I couldn't create shortcuts on SOME pages with drag and drop as I did usually. Today I formated the PC to start fresh, the problem remains!

examples: - https://flogarecords.com/store/shop/lp-mlp/sakis-tolis-among-the-fires-of-hell-lp-red-white-haze-exclusive/ When I try to create a shortcut with drag&drop a folder is created named: "SAKIS TOLIS - AMONG THE FIRES OF HELL LP (RED" And the shortcut is included inside.

- https://www.pronews.gr/amyna-asfaleia/politiki-prostasia/kolasi-sto-porto-germeno-ekkenonetai-o-mytikas/ When I try to create a shortcut with drag&drop a white file is created named: "Κόλαση στο Πόρτο Γερμενό" With size "0 byte", without extention.

The above are happening in SOME pages, not in all shortcuts. When I try to create the shortcuts on Opera they are created just fine. Perhaps that has to do with a bug in some update (windows or firfox)

Running Firefox 102.0 in Win 10. When I try to download a PDF file, I get (1) a dialog box saying the download failed, (2) two 0 byte files in the download directory with the name of the PDF file I'm trying to download, and sometimes (3) a PDF file with a filename of 8 random characters that appears to be the file I'm trying to download. How do I fix this?
