Hi, Firefox sync not work with changed useragent. I have changed useragent in (about:config): general.useragent.override Our company identify and block Firefox globaly in proxy servers. Why? I don't know (maybee dificult globaly Firefox updating for non admin user).

I open Firefox sync and try login there, but I see only progress (wheel).

I was watching anime today on some site and my firefox was downloading many files without my knowledge into my download folder. I'm worried that it can be some viruses? This is a screenshoot. Should i be worried? Thank you for help.

I have tried to upload files in several websites and the "upload" button isn't working. I tried in Safari and I'm not having this issue. It's an issue keeping me from working. Does anyone know how to fix it?

I use Last Pass for passwords & it's worked in the past on Firefox. After updating Firefox, the Last Pass extension in by toolbar is black - in the past I would click that, open the Last Pass page to sign in, then the icon turns red and functions. Now when I click the icon a frozen page comes up that never loads. I can sign in to the Last Pass webpage, but that doesn't turn on the extension.

Any advice appreciated - thanks!

Hi, new updates on Version 98.0.1 quite a hassle for me. It auto-download all my files even when I just want to view. Is there any other way to disable this feature? I opened Setting>Download but there is no disable button or checkbox for that. Please help me. Thank you in advance.

I am trying to print shipping labels from Amazon and a third-party web app running Firefox 103.0 64-bit.

Text prints just fine but images (barcodes, etc) that need to be scaled down do not do so causing them to be truncated on the page.

I have cleared print settings and tried two different printers to no avail. The documents/images print correctly from Chrome. I have tried using the system dialog to print but this also does not correct the issue.

Any help is greatly appreciated as I currently cannot use Firefox for the essential daily task of printing packing slip / mailing labels.

After updating to Firefox 103, everything in the browser including web pages, are way too big. Oversized. What the heck happened? Why do they do this? On the tool bar with the address field, on the right, I have a zoom icon, etc., and they're all much bigger!

I could adjust zoom, but this is not right. It's all messed up!

Yes I went into Customize Tool bar - Density - and it was already set to "compact - not supported"

I went into about: config - browser.display.os-zoom-behavior - changed to zero. Nothing happened.

I went into the windows settings - display - set to 125% which it always was. Changing to 100% didn't do anything. Went into display - Make display bigger - and it's 160, where I always had it.

Not happening in Chrome or Windows. So it's Firefox.

I use Mendeley Reference manager in Firefox. It used to work OK. Now I get a message "Firefox blocks extensions running on PDF files". This is just what Mendeley does. How do I get Firefox to allow this to happen again?

Currently @ Ver. 102.0.1 Problem remains. Since the update to 102.0 my Win10 PC has problems with the page update. When the scroll slider gets near the bottom the page, new images begin to load. This reload results in 3-15+ newly loaded Fb posts scrolling past so fast as to be invisible. I have to keep my cursor on the scroll slider and, when the loading begins, start scrolling up if I want to have any chance to easily find the last post I was reading. I have seen this behavior, grossly exaggerated, when I was viewing a video. The reload caused the viewing to pause and upwards of 15 newly loaded posts scrolled past in this rapid manner. My work requires that I am able to view pages of Facebook posts and this is now massively time-consuming and intolerable. I may have to change browsers in spite of my reluctance to do so.

Hi,

When I connect to my desktop via RDP, Firefox is crashing on my desktop. It has began after updating to last versions. Current versions are Firefox 102.0, Windows 10.

Thanks.

Since the most current Firefox update in June 2022, when in Yahoo Mail and downloading an attachment, as the download complete, the Yahoo Mail tab is automatically closing, requiring I to go to 'History', then 'Recently Closed' tabs to re-open it. This happens Every.Single.Time I download photos and scanned docs from email. Again, this has never happened before - only with the recent Firefox update. I have 2021 a MacBook Pro.

Random videos will not load following 100.0.2 install.

These symptoms started @ May 21. (See attached file "Recently installed")

This problem is 100% reproducible at: https://www.reddit.com/r/CatastrophicFailure/

Lenovo Thinkpad x140e Windows 7 (all updates installed) Mozilla 100.2.8174

Scrolling down the Reddit page, videos will auto-play when exposed, and stop when scrolled past.

A video not loading/playing will occur on different posts/videos, but will ALWAYS occur. Once this occurs some previously exposed / played videos, when scrolling up, will play when exposed again, and some will not.

This will also randomly occur on Youtube (also observed on Twitter a few times) when multiple tabs are open. Sometimes closing other open tabs corrects the problem. Other times closing Firefox and relaunching is required and is 100% effective.

I have additional diag data / Inspector log files and page source if needed.

Thank you in advance for your help and consideration. - LudditePro

I have Firefox 100.0.1 on my Mac desktop, and Firefox 100.0 on my MacBook Pro laptop. I can no longer access my Microsoft OneDrive account via the web on my desktop, but I still can do so on my laptop. I have gone through your posted troubleshooting steps for Firefox on my desktop, to no avail. How do I get my desktop back to version 100.0 so it will work again? I can access my OneDrive account via the web on my desktop when I use the Safari browser, so the issue is definitely with Firefox version 100.0.1, and not with my desktop.

I've noticed there is a "verified by Amazon" icon in my address bar next to the FF shield. How did it get there, can, or should, I remove it and how. I don't trust anything Amazon does, so if possible I would like it to be gone.

Starting yesterday, the preview images in GIS has been looking off center in Firefox (see attached). If I switch to protection mode the image looks fine. If I open up in any other browser it looks fine as well. I have already cleared my web cache and cookies, refreshed Firefox and then reinstalled it, changed my screen resolution settings, and nothing seems to be fixing it. There's no apparent settings in Google itself to adjust the image...it just started doing that in Firefox out of nowhere.
